Last time when I reported N mode problem i was using archive downloaded from site, just to show i am not lazy :) You can actually see from path of module, anyway, its not the point. N mode didn't work than, doesn't work now either. I have disabled all modes but N, still same issue, i can see Access Point, but I can't connect to it. iwlist wlan0 scan wlan0 Scan completed : Cell 01 - Address: 00:1E:58:B4:F6:83 Channel:11 Frequency:2.462 GHz (Channel 11) Quality=58/70 Signal level=-52 dBm Encryption key:off ESSID:"dlink" Bit Rates:1 Mb/s; 2 Mb/s; 5.5 Mb/s; 11 Mb/s; 6 Mb/s 9 Mb/s; 12 Mb/s; 18 Mb/s Bit Rates:24 Mb/s; 36 Mb/s; 48 Mb/s; 54 Mb/s Mode:Master Extra:tsf=0000000000d13580 Extra: Last beacon: 456ms ago IE: Unknown: 0005646C696E6B IE: Unknown: 010882848B968C129824 IE: Unknown: 03010B IE: Unknown: 2A0100 IE: Unknown: 3204B048606C IE: Unknown: DD1E00904C334C1003FFFF000000000000000000000000000000000000000000 IE: Unknown: 2D1A4C1003FFFF000000000000000000000000000000000000000000 IE: Unknown: DD1A00904C340B080800000000000000000000000000000000000000 IE: Unknown: 3D160B080800000000000000000000000000000000000000 IE: Unknown: DD0900037F01010000FF7F IE: Unknown: DD0A00037F04010001000000 modprobe -l ath9k /lib/modules/2.6.29.2/updates/drivers/net/wireless/ath/ath9k/ath9k.ko Regards Dmitri
