Poor performance with ath9k after use wireless-testing 2011-02-25

[anonymous]

two Atheros PB44, One of them works at AP mode, the other works at STA mode, with wireless-testing 2011-02-07, the max speed between them up to 6.x MB/s, I test with vsftpd server and flashfxp ftp client, but with wireless-testing 2011-02-25 and wireless-testing 2011-03-11, the max speed is only poor 80 KB/s!

BTW: the trunk version with kernel 2.6.37 crash on Atherson PB44, it tells:

Why do you mix multiple *different* problems in the same ticket? That makes no sense at all.

About your wireless issue: What kind of cards are you using, and did you test the different compat-wireless version with the *same* OpenWrt version?

I use Atheros AR9160 cards, I tried compile backfire r25965(the last version with wireless-test-2011-02-07), and get the same problem, so, I guess it must be some other problem, not the wireless driver.

After pathed gpiolib.c, I compiled trunk version r26244 for Atheros PB44, works fine, and still very poor wireless transfer speed!

[anonymous]

I tried trunk r26301 with wireless-testing 2011-03-24, and now the wireless transfer speed is normal!

[anonymous]

BTW, I tried r26291 too, still have wireless transfer speed problem.
