I am not using Ubuntu (Gentoo, vanilla sources, kernel 2.6.27), however I'm having the same problem, so hopefully this information will help.
I do not use NetworkManager (it didn't handle my wireless properly), so that is not the problem. I searched the driver source for the phrase, but could not find it anywhere - does anyone know where this error message originates? grep -rl "ProbeResp" ./ I used the above command to locate any strings within all files in the source directory and found nothing of use. However, using the above command to search for "No ProbeResp" in the kernel source directory (2.6.27) produced the following file, in which I found the error message: /usr/src/linux/net/mac80211/mlme.c (line 1059) Above, the following link was referenced: http://rt2x00.serialmonkey.com/phpBB/viewtopic.php?f=5&t=2081&p=30312&hilit=No+ProbeResp+from+current+AP#p30312 However, the file it references does not appear to exist within kernel 2.6.27. The file you are looking for to modify IEEE80211_MONITORING_INTERVAL is the above file (mlme.c). This is the constant that is referenced when a timeout is determined. I'll set it to a higher value (default seems to be "2 * HZ"), recompile, and post back with any success. Either way, it'll only be a temporary fix - we'll need to take it up with serialmonkey to figure out the real problem. Hope this helps. I use the driver rt61pci ======= dmesg | tail [41884.647257] wlan0: authenticate with AP 00:15:e9:76:1a:ee [41884.658208] wlan0: authenticated [41884.658208] wlan0: associate with AP 00:15:e9:76:1a:ee [41884.668257] wlan0: RX ReassocResp from 00:15:e9:76:1a:ee (capab=0x431 status=0 aid=5) [41884.668257] wlan0: associated [41892.844239] wlan0: no IPv6 routers present [68822.729255] wlan0: No ProbeResp from current AP 00:15:e9:76:1a:ee - assume out of range ======= ======= lspci | grep RT 01:07.0 Network controller: RaLink RT2561/RT61 802.11g PCI ======= ======= uname -a Linux mikegerwitz-pc 2.6.27-rc4-mikegerwitz #1 SMP Sat Aug 30 20:39:45 EDT 2008 x86_64 AMD Athlon(tm) 64 X2 Dual Core Processor 5400+ AuthenticAMD GNU/Linux ======= Wireless works fine until this error occurs, seemingly randomly.
