FS#649 - WDS not working on ath9k-htc

Supply the following if possible:
- Device problem occurs on: Any device with an wifi USB adapter with the chipset AR9271 (TPLink WN722N in my case).
- Software versions of LEDE release, packages, etc: Latest trunk LEDE versions.
- Steps to reproduce

 

Configure the USB AR9271 adapter as WDS AP, try to associate any other router as WDS Client (in my case the WDS Client is a TPLink WR741ND router, also compiled with latest trunk).
They both associate correctly, but there is no connection between them.

Here is a hostapd log on the WDS AP:

I think the error Mon Mar 20 14:05:03 2017 daemon.err hostapd: nl80211: EAPOL TX: No message of desired type has something to do with WDS not working?.

If there is any other info, tests etc you require feel free to ask.

I just did a test with OpenWRT 15.05... WDS still not working and there is no EAPOL TX: No message of desired type error message so it has nothing to do with WDS not working...

I guess the problem is on the ath9k-htc firmware ?

Miguel commented on 22.03.2017 11:39

More tests... and i found a workaround!

I had to add nohwcrypt=1 to /etc/modules.d/ath9k-htc

root@MainRouter:~# cat /etc/modules.d/ath9k-htc
ath9k_htc nohwcrypt=1

But the performance is not optimal, speeds between WDS wifi link are around 10Mbps~~ ...

After doing more tests;

  1. Compiled my own ath9k-htc firmware from here https://github.com/qca/open-ath9k-htc-firmware .
  2. Replaced htc_9271-1.4.0.fw on /lib/firmware/ath9k_htc , then rmmod ath9k_htc and modprobe ath9k_htc , restarted wifi, removed nohwcrypt=1
  3. Still disabled WMM Mode on the interface with the USB adapter.

The performance now is better, up to 15Mbps~~ speeds, still HT20 with WMM Mode disabled, even with the compiled firmware WDS doesn't work if i have WMM Mode enabled.
