Hi, I have a new PC running ubuntu 9.10 and ath9k:
# lspci -nn | grep Atheros 04:00.0 Network controller [0280]: Atheros Communications Inc. AR928X Wireless Network Adapter (PCI-Express) [168c:002a] (rev 01) # modinfo ath9k filename: /lib/modules/2.6.31-17-generic/updates/cw/ath9k.ko license: Dual BSD/GPL description: Support for Atheros 802.11n wireless LAN cards. author: Atheros Communications srcversion: 918698AEA3CBE61D0E996E6 alias: pci:v0000168Cd0000002Esv*sd*bc*sc*i* alias: pci:v0000168Cd0000002Dsv*sd*bc*sc*i* alias: pci:v0000168Cd0000002Bsv*sd*bc*sc*i* alias: pci:v0000168Cd0000002Asv*sd*bc*sc*i* alias: pci:v0000168Cd00000029sv*sd*bc*sc*i* alias: pci:v0000168Cd00000027sv*sd*bc*sc*i* alias: pci:v0000168Cd00000024sv*sd*bc*sc*i* alias: pci:v0000168Cd00000023sv*sd*bc*sc*i* depends: mac80211,led-class,ath,cfg80211 vermagic: 2.6.31-17-generic SMP mod_unload modversions parm: debug:uint parm: nohwcrypt:Disable hardware encryption (int) It's performing quite badly, giving ping-times in the area of 100ms (when pinging from host x, but around 1ms when pinging to host x), and frequent delays/pauses in TCP connections. I tried to run the module with debug=1, and there was something that looks suspicious to me: Jan 16 01:21:09 tv kernel: [ 4432.020973] ath9k: NETWORK SLEEP -> AWAKE Jan 16 01:21:09 tv kernel: [ 4432.026534] ath9k: AWAKE -> NETWORK SLEEP Jan 16 01:21:09 tv kernel: [ 4432.123358] ath9k: NETWORK SLEEP -> AWAKE etc etc.. in other words, it seems to oscillate like this at a steady rate of about 10-20Hz. Is it supposed to be like this, or does it indicate a problem? Also, once in a while (every couple of minutes or so), there are bursts of these: Jan 16 01:18:09 tv kernel: [ 4252.157169] ath9k: ah->misc_mode 0x4 I'd appreciate any advice on this. Thanks, -- Frode V. Fjeld _______________________________________________ ath9k-devel mailing list ath9k-devel@lists.ath9k.org https://lists.ath9k.org/mailman/listinfo/ath9k-devel
