I'm facing similar issues and assuming it was a router incompatibility

I believe the powersave option is a no-op with iwn(4) so I am
not surprised it doesn't change anything.

Well, it seems something strange is going on since it works with Linux.

It is not clear whether the problem is with sending or receiving.
I would guess it is more likely that iwn(4) has some problem with
sending data, rather than receiving it. Both have to work to associate
successfully.

You can enable some debug output like this:

  ifconfig iwn0 debug

Look in /var/log/messages. Any beacon received should be mentioned there,
and in case a WPA handshare is attempted you should see this as well.

Perhaps the problem has to do with regdomain settings? iwn(4) does not
do anything about those -- it relies on hardware/firmware defaults.
Does Linux print anything about regulatory domains in its dmesg?

Do you also happen to have this AP on a 5GHz channel or is this
AP on 2GHz only? If iwn(4) is trying to connect on 5GHz instead of 2,
that would explain why it doesn't work well through walls.

Interesting. It seems that on OpenBSD the reception is quite weak.
I've connected, HOWEVER, I have to be in the same room as my router!
On Linux I can be anywhere in my house.

I tried disabling powersave (-powersave), and still I have to be very
close to my router. My phone can connect to it no problem anywhere in
the house. Does anyone have any clue what's going on? Is it possible
that the driver is permanently set on a power save mode?

iwn: Centrino Ultimate-N 6300 scans, doesn't dhcp?

2017-01-25 Thread Austin Bentley
I've got a ThinkPad x220 with a Centrino Ultimate-N 6300, and I'm
trying to get it to connect to a WPA1 WiFi network. Network has a
password.

Steps taken thus far:
Tested WiFi on Linux

Update WiFi drivers with fw_update via ethernet

Verified /etc/firmware/iwn-6000 exists (it does)

dmesg:
 dmesg | grep iwn
 iwn0 at pci2 dev 0 function 0 "Intel Centrino Ultimate-N 6300"
 rev 0x3e: msi, MIM0 3T3R, MoW, address: xx:xx:xx:xx:xx:xx

Scanning networks works:
 ifconfig iwn0 scan
 iwn0: flags=8843 mtu 1500
   lladdr xx:xx:xx:xx:xx:xx
   index 2 priority 4 llprio 3
   groups: wlan
   media: IEEE802.11 autoselect (DS1 mode 11g)
   status: no network
   ieee80211: nwid MYSSID chan 6 bssid yy:yy:yy:yy:yy:yy -58dBm
 wpakey 0x wpaprotos wpa1,wpa2 wpaakms psk wpacipchers
 tkip,ccmp wpagroupcipher tkip
 nwid MYSSID chan 6 bssid yy:yy:yy:yy:yy:yy -58dBm HT-MCS15
 privacy,short_slottime,wpa1
 ... #other networks
 ...

Of course, I attempted `dhclient iwn0` with both /etc/hostname.iwn0,
and `ifconfig iwn0 nwid MYSSID wpa wpakey  up`, and both
achieved this:
 dhclient iwn0
 iwn0: no link ... sleeping

The WiFi light on my laptop is constantly blinking too.
Does this indicate anything?

Thanks,
