[Bug 218908] Missing usbdevs for TP-Link WN-821N v5

--- Comment #10 from Alexander Sherikov  ---
Played a bit more with parameters without any success and also tried it in
Linux where it fails in the same way until I force wext driver when starting
wpa_supplicant. Don't want to waste more time on this, it was a backup option
anyways.

It works for me with wpa-psk on yesterdays 14.0-CURRENT with this in rc.conf:

wlans_rtwn0="wlan0"
ifconfig_wlan0="WPA DHCP"
create_args_wlan0="country DE regdomain ETSI"

and the appropiate entry in wpa_supplicant.conf connecting to an 11g AP.

Good luck,

Kai-Uwe

Hm, is there a regression in HEAD or a catch in configuration? I have WN821N
which is detected in the same way as above and wpa_supplicant also timeouts
during authentication with WPA-PSK.

Sidenote: wpa_supplicant hangs if restarted, device must be unplugged to fix
this.

Seems this was handled in r342156 and r342703 for rtwn_usb_attach.h from what I
can see.

The bug can be closed. Both devices have been added to usbdevs and the WN821N
v5 now works with WPA-PSK.

Thanks,

Kai-Uwe

After some testing it turns out that the WN821 is kind of deaf, especially
after sending. Mabey someone finds a hint in the linux driver from the vendor
at

http://www.tp-link.com/us/download/TL-WN821N.html#Driver

in which I found the device ID and chip set to use:

/*===TPLINK ID===*/
{USB_DEVICE(0x2357, 0x0107),.driver_info = RTL8192E}, /* TP-Link -
Cameo */

Quite possibly there are some calibration hints in the source but I didn't spot
it on a first look. I was unable to compile the driver under Linux kernel 4.9,
so I cannot test there either.

The WN821N behaves really strange. Today ifconfig wlan0 scan showed only three
APs instead of about 30 like yesterday. After repeating it several times with
the same result I shutdown, rebooted and now it shows 30 again but an AP in 3
meters distance is sometimes present and sometimes missing. Turning debugging
on with sysctl -w dev.rtwn.0.debug=1 shows a bunch of messages like this:

Ok, I will look at the frames actually sent with a Linux laptop and kismet, but
it will take a few days. Looks like a good opportunity to learn something new
about the kernel code ;-)

I just found out that the WN821NV5 is unable to connect with WPA-PSK. I only
tested with an unencrypted access point. The WN722N connects without problems
with the same configuration files. I get no error reports in dmesg, ifconfig
shows

ifconfig shows the desired network at S:N -65:-95 but wpa_cli is unable to
connect: Authentication timed out.

I will try to get some debug info and play with hardware crypto, etc.

Looks good to me. Do you have dmesg for the adapter?
