Ok, I have upgraded my kernel to 2.6.39 and it works somewhat better than the old one. But, I'm still having problems with my AP. Many times after power on, I get lots of GTT interrupts and things are not working well. If I say "iw dev wlan0 survey dump" at that point, noise value on channel I use is only -88-90 dBm, so there shouldn't be too much noise on the used channel. Also, even when things seems to be running ok (stations can connect and transfer data), there are lot of errors (phy, underrun, crc). Is that normal? My station is only one meter away from my AP. cat /sys/kernel/debug/ieee80211/phy0/ath9k/recv CRC ERR : 26415 DECRYPT CRC ERR : 1 PHY ERR : 245603 MIC ERR : 0 PRE-DELIM CRC ERR : 0 POST-DELIM CRC ERR : 0 DECRYPT BUSY ERR : 0 UNDERRUN : 245592 TIMING : 0 PARITY : 0 RATE : 0 LENGTH : 11 RADAR : 0 SERVICE : 0 TOR : 0 OFDM-TIMING : 0 OFDM-SIGNAL-PARITY : 0 OFDM-RATE : 0 OFDM-LENGTH : 0 OFDM-POWER-DROP : 0 OFDM-SERVICE : 0 OFDM-RESTART : 0 FALSE-RADAR-EXT : 0 CCK-TIMING : 0 CCK-HEADER-CRC : 0 CCK-RATE : 0 CCK-SERVICE : 0 CCK-RESTART : 0 CCK-LENGTH : 0 CCK-POWER-DROP : 0 HT-CRC : 0 HT-LENGTH : 0 HT-RATE : 0 RX-Pkts-All : 635344 RX-Bytes-All : 39393486 Sami _______________________________________________ ath9k-devel mailing list ath9k-devel@lists.ath9k.org https://lists.ath9k.org/mailman/listinfo/ath9k-devel
