Thanks I found a AR9271 on Amazon for $12.00 much better than $50.

Re: USB WiFi Adapter

[John Scott]

I would like to recap some points that've already been shared in this
thread and also give some advice for those who want to use libre USB Wi-
Fi adapters with Debian GNU/Linux.

The best one can do with free software right now is 802.11n. There are
two main families of chipsets for USB wireless adapters, ath9k_htc
(AR7010 & AR9271) and "carl9170" (AR9170). The latter has some issues
with 802.11n setups, so the former should be preferred.

AR9271 is never dual-band capable; it is always 2.4GHz only. Whether an
AR7010 or AR9170 adapter is dual-band capable depends on what wireless
chip it is paired with. In general dual-band capable AR7010 adapters are
somewhat challenging to find, but dual-band AR9170 adapters are easy to
find. 

For those interested in the technical details, ath9k_htc uses a custom
Xtensa CPU and as such requires a custom cross toolchain. Currently we
build this free firmware in Debian completely from source, which is
quite an achievement! I'm the current maintainer of open-ath9k-htc-
firmware in Debian (more on that package later), but much credit goes to
the former maintainer Oleksij Rempel, especially for his encouragement
of me. AR9170 uses an ordinary SuperH-2 CPU, and as such the carl9170
firmware can be built with a standard SuperH cross toolchain. I've
currently packaged gcc-sh-elf and binutils-sh-elf in Debian Unstable, so
that when I get around to it (or when someone I can mentor expresses
interest 😉️) we can build carl9170 from source as well.

The firmware for AR9170 (AKA carl9170) is currently shipped in the
firmware-linux-free package. However, due to complicated historical
reasons, the firmware for ath9k_htc is in a separate firmware-ath9k-htc
package, which tragically is not installed by default like all other
free firmware is. There is a common misconception that because ath9k_htc
adapters don't work out-of-the-box, but because the firmware also
happens to be in the non-free firmware-atheros package, that this is
actually non-free. That's not true; it's a fluke that the ath9k_htc
firmware is in firmware-atheros, and we're working to get it removed
from there.

So here's what I want to emphasize: if there's a chance you'll be using
an ath9k_htc adapter, install the firmware-ath9k-htc package. If you
don't know whether the adapter you have (or will have) has ath9k_htc,
installing that package won't hurt.

In general, for issues such as this, one should consult the Free
Software Foundation's Respects Your Freedom program, which certifies
devices that are guaranteed to be the best one can do with free
software. ThinkPenguin is just one of many vendors that sells USB
wireless adapters that work with free software+firmware.

Also, neither carl9170 nor ath9k_htc work with the Debian Installer
right now, so if one needs to install over Wi-Fi, the Live installer
should be considered.

Disclaimer: I have been compensated by ThinkPenguin, an FSF RYF vendor,
for my Debian wireless packaging work.

Very old Atheros chipsets have some free firmware, I think.

If you can find them, those using Ath9k now have a free firmware and Atheros
 AR9271 

Essentially almost none now - which is why ThinkPenguin are so expensive. Oh
and as someone pointed out, you still need *a* blob to deal with regulatory
stuff, esp. in USA.

See also one of the very valid reasons why we're talking about firmware over
in debian-vote at the moment.

Re: strange problem with usb wifi adapter

[Long Wind]

i've been able to find out why official debian installer needn't non-freeware, 
thanks for David's explanation
  
run linux and set up my adapter with non-free mt7601u.bin
then reboot to start debian installer
this time installer can use my adapter without non-free firmware 
firmware loaded can survive reboot, as David explains

Re: strange problem with usb wifi adapter

[Long Wind]

Curt, i have some good news, i try buster and bullseye *netinst.iso today, both 
ask me for  mt7601u.bin

it's not easy for me to explain why they don't last time

maybe installer find firmware somewhere in my PC
(i have installed linux before)
but why they don't install firmware to my target device?
maybe firmware happen to be in partition where debian 10/11 are to be installed

but installer has other bugs, it can't detect my netgear adapter though kernel 
support it, it can't proceed just because it's on 1st device.

i think i've been very unproductive bothering with these issues

So: if it works - you need firmware-linux-nonfree which pulls in 
firmware-misc-nonfree [For Bullseye]

  * MediaTek MT7601U firmware, version 34 (mt7601u.bin)

is in firmware-misc-nonfree.

If you use the unofficial non-free installer, that would be found on
boot, I think. If you then install a desktop environment, you would get
the ability to configure it with network-manager or whatever other utility.

Hope this helps, all the very best, as ever,

No problem; I was thinking later my remark was actually pretty stupid
(ruining my stellar reputation here), but I'd seen this (believing if
there was a kernel driver that meant it was open source or something)

 https://cateee.net/lkddb/web-lkddb/MT7601U.html

i think official buster debian-10.11.0-i386-netinst.iso has non-free firmware,

That sounds plausible. What I miss in the comparison is the complaint
that it couldn't load the firmware, like in my case:

 [   54.996555] iwlwifi :03:00.0: firmware: failed to load 
iwl-debug-yoyo.bin (-2)

But perhaps this driver is silent? I don't know.

The fact here, though, is the OP's wireless card was "configured" during
the installation process and worked perfectly. What we're trying to
discover is how and why his wireless worked with the official Debian
installer if it requires non-free firmware to function after a hard
reboot.

These days an exception to this is when the installation is done over a
wireless link and a DE is not selected. See the bug reports for netcfg.

As another hint to debugging, you may look into dmesg's output (do, e.g.
"sudo dmesg | less") for clues. An idea to clear the above question
would be to compare dmesg's output while the installer is running with
the one after the installed system boots.

Here's "my" kernel's output to dmesg while it's trying to feed "my" WiFi
hardware its firmware, to give you a rough idea on what to look for.
Searching for "wifi", or for your wifi's kernel module's name seem to be
good approaches:

  [   54.906353] Intel(R) Wireless WiFi driver for Linux
  [   54.906565] iwlwifi :03:00.0: can't disable ASPM; OS doesn't have ASPM 
control
  [   54.996363] iwlwifi :03:00.0: firmware: direct-loading firmware 
iwlwifi-6000g2a-6.ucode
  [   54.996531] iwlwifi :03:00.0: loaded firmware version 18.168.6.1 
6000g2a-6.ucode op_mode iwldvm
  [   54.996555] iwlwifi :03:00.0: firmware: failed to load 
iwl-debug-yoyo.bin (-2)
  [   54.996617] firmware_class: See https://wiki.debian.org/Firmware for 
information about missing firmware

So it seems to load some iwlwifi-6000g2a-6.ucode, which seems to work
But that one "...-yoyo.bin". What that "-2" means is anyone's guess, but
my gues would be "No such file or directory" (keeping with the good old
ERRNO tradition, why should the kernel folks break that?).

Happy digging :)

If it's a particular Mediatek chipset, then the firmware for it may be
in the firmware-linux-nonfree metapackage - which also pulls in 
firmware-misc-nonfree which is the package where the actual driver is. 
99% of current wireless chips need additional firmware to operate correctly.
https://packages.debian.org/bullseye/firmware-linux-nonfree 

The fact of having trouble installing via wifi is one of the reasons why
I've started suggesting that people should use the unofficial installer which
includes non-free firmware for wifi chipsets. If anyone wants to use the 
official image to install - it will generally work for wired connection 
over Ethernet - which would also allow you then to add the non-free firmware
for the wifi card. [For a virtual machine, the official image is ideal because 
that then  depends on the host machine anyway.] 

If your card needs firmware, then it's quite possible that the official 
installer doesn't configure it - though you do get a prompt saying something 
close to "Your device may need nno-free firmware. Use non-free or load 
firmware now"

Hope this helps, with every good wish, as ever

The configuration used during the installation is passed on to the final 
system. It has been like this since at least sarge.

It's not a theory, it's a hypothesis based on what you have told us.
Each new fact that you reveal can be used to refine or reject it.
You can of course do this more easily than I can, as I don't have
access to a device like that.

Every step matters in your research: power changes, booting,
un/plugging, choice of socket, etc, and their precise sequence,
if you want to get past just posting anecdotes.

I'm not even certain whather your OP was actually
a strange problem, or just a strange phenomenon.

Firmware isn't like most software, where it's read from the
filesystem whenever it's needed. It's not even like heavily
used software, where it's kept in cache in memory to avoid
having to read the filesystem so frequently.

What you appear to be describing is a case where the kernel
module loads some firmware into the chips inside the device,
making it work correctly. And until the power is removed
from those chips, the firmware remains in the chips.

In days of yore, many people had to initialise some internal
devices in PCs using DOS, and then perform what was termed
a warm/soft reboot to load linux without losing the effects
of the initialisation.

Cheers,
David.

I don't know whether the problem is firmware, or a regression in the

This kind of problem is fairly normal with installers: they often use
features within their own code which they do not necessarily install in
the target system. The installer will have loaded the necessary firmware
for its own use, but will not assume that the installed system also
needs it, especially if you don't ask for non-free software.

I did my first netinstall without asking for expert mode (I assumed it
would do a decent job by itself, and I did not consider myself an
expert) and this was when I had only a couple of computers and used
hosts files and static addressing. Under those conditions, the
installer did not install Ethernet networking in the installed system,
despite having used it itself in order to make the installation. 

I reported this behaviour as a bug and was rather tersely told that it
was a feature. No expert + no DHCP = no Ethernet. OK, I could have been
building an isolated certificate authority machine, but surely then I'd
have used expert mode...

I don't know if installers still do that, it's many years since I ran a
network without DHCP, and I *always* use expert mode, even for routine
throwaway installations.

Hi Long Wind,

1. Which Wifi adapter? - lusb may tell you. This is important: because
one works without firmware, it doesn't mean they all will. Firmware is
specific to chipset from the manufacturer.

2. How are you bringing up the interface for the Wifi adapter to connect?

3. Is the Wifi adapter permanently plugged in or are you removing it and 
replugging it.

If you can give clear answers - it is especially helpful if you can
show approaches you have tried / commands you have run / logs - we 
can help you better.

With every good wish, as ever,

Actually, just a trivial technical problem: while upgrading my server,
Debian's mailer got too many bounces and (rightfully) kicked me out.
Combined with the hot mess I'm currently in, I didn't notice at first.
Now I'm resubscribed.

> i wonder if my wifi adapter really needs nonfreeware

If it doesn't work without, you have at least some evidence towards
that. I'm currently too distracted to look deeper, but there is sure a
way to see what the kernel is doing while pushing the firmware to your
WiFi adapter. I'd expect to get a hint in the logs.

That's what I was wondering. What's it using to successfully function
before you have to install the nonfree package after the next boot up?
Would comparing something like lsmod before and after provide any
insight?

That's correct: many (most?) wifi hardware these days needs non-free
firmware. If you want to avoid that, having a look at [1] *before buying

I briefly though of that but when it was working the internal one used 
proprietary drivers/firmware to work with Linux. Also, if I change 
laptops the new one have a new radio built-in and I wanted it to be able

It doesn't matter what distribution of GNU/Linux you use- if there is no free
firmware available for the device, there is no free firmware available for the
device. wpa_supplicant is just a program used to authenticate with
WPA-encrypted networks over a wireless LAN interface. It still requires
underlying firmware for the operating system to be able to control the device.

The reason it worked out of the box in Arch is because the Arch kernel is
mainline Linux, which has proprietary blobs, unlike Debian's de-blobbed kernel
or Linux-libre.

That was more or less true back in the 11n days.  Nowadays we're back to
having trouble: most chipset have some kind of support, but many of them
have support that's not integrated in the kernel, i.e. you need to
compile the kernel module separately, and it only works for some
versions of the kernel and there's no guarantee that it'll still work
5 years from now.

If you search the web for comments about using those Asus 11ac dongles
it seems they don't "just work".

And certainly not with debian since debian hasn't got netctl.  I forgot

Re: Suitable USB WiFi Adapter

It may have, but the proprietary software is unnecessary if you use 
archlinux to install it and get it up and running.  You need 
wpa_supplicant; iw, dialog and netctl packages installed.  Now I have an 
rt2780 usb wifi adapter and have this working.  Once those packages are 
installed, you run netctl list and the first string that returns will be 
at least one wifi possibility.  The next thing to do is type netctl 
enable network string from netctl list.  Then reboot the computer and 
watch your wifi network come up.  What I just described I have no idea 
how to do with any form of debian.  Earlier I documented what happened 
with the firmware debian disk on an acer 5003 notebook which is an amd 
clone and my real amd k8 athelon machines.

Just check if the driver is in the mainline kernel, and it should be
supported on any Linux, unless the distribution for some reason decides
to strip it out.

In this case it seems to be covered by the ath9k_htc driver:

I don't know why you'd spend anything extra for USB3--your old Dell doesn't 
support that, and if you get a new laptop, the wifi will be built-in and 
working. The little $6 adapter that I mentioned
earlier worked fine with PCLinuxOS for the short distance that it worked over. It 
"just worked."

I said, "commonly used."  Either "surveillance" or "controllable by
wireless" places the device in a very different category.

I have something similar, quite like the possibility to use an external
antenna. 

But it's Ralink, so it has proprietary firmware right?

The laptop is a Dell Latitude D620. Because of its age I'm not inclined

it if I recall there was a message with the name of the missing driver. 
I did an Internet search and although the driver is proprietary I was 
able to download it at no cost.


A couple people suggested off-list I replace the older laptop. The Dell 
only supports 32-bit Linux but since my portable work is mostly email 
and web that's not a limitation. I have a 120GB solid state drive in it 
so what it may lack in processor speed it makes up for with quick I/O.


I like the idea of fixing my problem with an external adapter that is 
supported by free software. Also, the attraction of getting an adapter 
that supports USB 3.0 and the newer WiFi specifications/modes is 
attractive. I'm not opposed to spending the money, I just like to be 
frugal and get the most value for what I spend.

The antennas on WiFi routers typicaly are about six inches long; so a
physically compact dongle must compromise the antenna system.

A USB 2.0 cable can be up to ten feet long; use that and duct tape to
position the dongle for best reception; or put the dongle on a bookshelf
or over a curtain rod; or use a loop of twine and a thumbtack to position
the dongle on a wall.

With high frequencies, even a few inches difference in location can made a
significant difference in reception, so experiment.

Some ASUS adapters come with a six-inch semi-rigid gooseneck USB cable so
you can adjust the position of the dongle while keeping it close to the
computer.

If you just want to use it in the house, it will probably be OK, but to work 
with Hotspots out in the open a couple of blocks away, or whatever, it would 
not work. I don't remember the name of it, but obviously

it did not have sufficient antenna in such a small package. You should look for

Just a tip, get a model that has a connector for an external antenna,
unless you know you will always be in a place with great reception.

This seems to be a Realtek RTL8188CUS device. So should be supported by
the rtl8192cu driver. 

You need the realtek-firmware package from non-free.

I don't know much about Yocto, but www.yoctoproject.org/downloads 
doesn't show anything that looks like 3.8.7.  So I think that number 
must refer to the linux kernel and you should make sure you're trying 
out the dongle on your Galileo when it's running the latest (3.12) 
image.

There are usually two drivers for Ralink devices: one from the 
manufacturer, and one from the rt2x00 project.  The driver you showed 
working in Ubuntu was from the manufacturer, which is not part of the 
mainline linux releases.  I think your device is also supported 
by the rt2x00 project (see below) but maybe not by the kernel you're 
using.  From my experience, if it were just a missing firmware issue, 
you might see something more in dmesg output, trying to load the 
correctly identified driver but complaining about missing firmware files.

I think the rt2x00 driver supports your dongle, based on messages on 
their mailing list:

- It looks like your devices usb id got added in July 2013
  
http://rt2x00.serialmonkey.com/pipermail/users_rt2x00.serialmonkey.com/2013-July/006283.html

- Some people report using very similar (one maybe the same?) devices 
  recently (November and February), though with problems using hostapd
  
http://rt2x00.serialmonkey.com/pipermail/users_rt2x00.serialmonkey.com/2013-November/006525.html
  
http://rt2x00.serialmonkey.com/pipermail/users_rt2x00.serialmonkey.com/2014-February/006553.html
  
http://rt2x00.serialmonkey.com/pipermail/users_rt2x00.serialmonkey.com/2014-February/006555.html

Anyway, you might get better help writing to the rt2x00 list, or maybe 
try e-mailing the specific people who wrote the messages above what they 
did to get their devices working.  (It's not a very active list.)

As you found by trial and error, you can't just copy kernel modules
between kernel versions.
As you also found out, your Debian installation on the Intel Galileo

support for the Ralink chip in your wifi dongle.
As I can see it (but I'm by a long way no kernel expert), you've got few
options:

Anyhow, with ralink there are two ways to get your hardware to work. You
can use the kernel driver (rt2800usb) or build the staging driver
(ralink's version) with the source code from the website.

 From having scanned through a few links, the "sta" part of the module on
your Ubuntu machine say it's a "staging" driver, i.e. something that
hasn't made it into the main kernel code yet. Whether or nor that
indicates it was compiled from the Ralink source or whether it came with
the kernel (where its source would have been in the staging tree) I
cannot tell.

Anybody more knowledgeable here able to chip in?



More knowledgeable? No.
But my google-fu feels strong ;)

That is an interesting possibility. However, part of our problem is that 
we really don't want to have to rely on a compiled driver because we're 
deploying remotely and we need to be able to depend on the device 
surviving updates.

Thanks!



Kind regards

As you found by trial and error, you can't just copy kernel modules 
between kernel versions.
As you also found out, your Debian installation on the Intel Galileo 
board (did I guess this right?) 
Bang on. Galileo is an amazing little platform that does *nearly* 
everything we need. :)
runs a kernel version that has no support for the Ralink chip in your 
wifi dongle.
As I can see it (but I'm by a long way no kernel expert), you've got 
few options:


-- upgrade to a newer kernel (probably 3.12 or newer). Is there 
anything available for your board?

No. 3.12 is the latest (and, I believe, only) Yocto image available.
I'm still digging, but no ringing bells yet.
Thanks!

Now, in your non-working system, do you have the matching firmware

Have you searched for "linux firmware ralink rt3573"? Have you seen 
for example this forum report which looks like Ralink doesn't know all

The trouble might be in vermagic (the Debian Galileo is running only

we need a system that will survive system updates and upgrades (these 
devices will be operating remotely and we can't afford to lose them if

almost sure it just loaded on its own. Either way, that route won't help 
for our Debian system. And that's the problem with the

USB WiFi adapter doesn't work with Wheezy (but does work with Ubuntu)

[dclinton]

Hi,
I've been having all kinds of trouble finding a dual band USB WiFi 
adapter that will work with Debian Wheezy and I hope someone here can 
help. Our best (and pretty much last) hope is the TP-Link N900 
TL-WDN4200. Using it successfully on Ubuntu 13.10, lsusb identifies the 
chipset as


   RT3573 Wireless Adapter (Ralink)

and iwconfig assigns it:

   ra0 Ralink STA

lsmod reports that the adapter is using the rt5572sta driver.

However, when I insert it into a Debian machine - whether its my Intel 
Galileo running a full Debian image or my own Ubuntu PC running a Debian 
live USB session - I'm having no luck. Dmesg identifies it with only:


   usb 1-1: new high-speed USB device number 3 using ehci-pci

lsusb correctly sees it as:

   ID 148f:3573 Ralink Technology, Corp. RT3573 Wireless Adapter

but that's where the fun stops. Here's iwconfig:

   lono wireless extensions.
   eth0  no wireless extensions.

iw list gives me this rather cryptic message:

   nl80211 not found

and the only remotely relevant reference in lsmod is

   ehci-pci

I've installed firmware-ralink and searched for an appropriate rt5572sta 
package. I found an rpm for OpenSuse here:


   
http://www.filewatcher.com/m/rt5572sta-common-2.6.1.3-6.3.noarch.rpm.15942-0.html

converted it to deb using alien and installed it, but there was no 
change. (It was a long shot in any case.)

There is supposed to be a driver here:

   http://www.mediatek.com/en/downloads/

but there's something wrong with their page and it doesn't actually 
download (I've sent them an email for help).

Does anyone have any ideas?
Thanks so much!

Things don't just stop working, most likely there was some change in 
your setup. You should thoroughly investigate any changes that may have 
influenced this, not excluding hardware.

As I said in my mail, it was working with wpasupplicant and wicd. Then
it stopped working. Now I downloaded latest drivers from their site
and installed it and blacklisted original kernel drivers. Now it is
working. It needs to observed further.

But the very next line reads:

"For the specifics about how much of your card is supported, please
refer to the driver page listed for your card."

IIUC, the driver docs will generally tell you what has been
implemented.

A bit puzzled about the disclaimer, though:

‘This list doesn't specify anything about how much of your card is
supported. So a card that only works without encryption is listed the
same as one that also has support for WEP/WPA.’

Not sure I want to donate my bandwidth to any TDH that might sniff my
available presence the minute I cruise along in their neighborhood...

What's worse, the vendors themselves do not care about the chipset,  
often releasing new models with different chipsets but keeping the  
same model number.

HCL lists are aimed to enumerate devices and their modules that work out-
of-the-box, have problems for setting up or that don't work at all. With 
that information you can go then to the store and buy the device with a 
little more confidence (not 100% but is better than nothing). So if your 
device uses "intersil/prism" or "realtek" chipset and that chipset is 
listed there and marked as "works/detected", then there are many chances 
that it works fine.

True, that information is not always easy to find (not present even in 
technical specs) but Google helps a lot here.

Anyway, I thought you were asking for a place where to put that your USB 
dongle works fine so others users can benefit form that information :-)

Had you bothered to ask in advance on this list -- and had I seen your  
post -- I could have told you that I have a v3 card and that the v3  
model works in Squeeze. I could have told you also that it does *not*  
work in stock Lenny (although it does in newer, backported Lenny  
kernels). I think that the v2 model works in stock Lenny, but have no  
means of checking that.


Anyhow, all's well that ends well.

Debian has a wiki, maybe you can get an account to edit/add this  
useful

data:

http://wiki.debian.org/WiFi#USBDevices

Also, mentioning it here is a good way to broadcast the good news ;-)



You should probably add your lsusb output too. That's because not all  
WG111 are created equal: IIRC, the WG111 has switched chipsets -- and  
consequently, drivers -- when going from .v2 to .v3. A good resource on  
Linux-compatible wireless adapters is the Backtrack website  
http://www.backtrack-linux.org/ because they also gather information on  
the "monitor" mode of various cards.

Netgear WG111 USB wifi adapter works with squeeze / gnome

[Peter Tenenbaum]

I recently had to add wifi to my squeeze / gnome desktop.  Based on some
reviews I bought a Netgear WG111 USB wifi adapter, and I found that when I
plugged it into a USB port on my desktop it worked instantly -- no
configuration or package installation necessary.

Is there a repository where these sorts of success stories are tracked?

Heh no worries. Thats the whole reason excellent man pages and /usr/share/doc/ 
exist ;-)

Have fun.

Thanks for the pointer. I had been a bit puzzled about that, because of
being able to supposedly configure wifi via /etc/network/interfaces, but
I've installed the wpasupplicant package now and - after a lengthy bout with
the READMEs, it's working fine :)

Thank you!

You need wpa_supplicant -

everest:~# aptitude search wpasupplicant
p   wpasupplicant- Client support for 
WPA and WPA2 (IEEE
802.11i)


Hth.
