Yeah, doesn't look like its NetworkManager from what I can tell. I don't notice any scanning going on, etc. Thanks for all the help. I guess the code for the channel changes just isn't fast enough ? This is what I get in dmesg: [ 174.026110] wlan1: associated [ 207.799194] wlan1: deauthenticated from 30:46:9a:10:49:f7 (Reason: 7) [ 208.065258] cfg80211: All devices are disconnected, going to restore regulatory settings [ 208.065265] cfg80211: Restoring regulatory settings [ 208.065269] cfg80211: Calling CRDA to update world regulatory domain [ 208.070474] cfg80211: World regulatory domain updated: [ 208.070478] (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp) [ 208.070482] (2402000 KHz - 2472000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) [ 208.070486] (2457000 KHz - 2482000 KHz @ 20000 KHz), (300 mBi, 2000 mBm) [ 208.070489] (2474000 KHz - 2494000 KHz @ 20000 KHz), (300 mBi, 2000 mBm) [ 208.070492] (5170000 KHz - 5250000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) [ 208.070495] (5735000 KHz - 5835000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) [ 213.390525] wlan1: authenticate with 30:46:9a:10:49:f7 (try 1) On Fri, Oct 1, 2010 at 11:19 PM, Christian Lamparter <chunkeey@xxxxxxxxxxxxxx> wrote: > On Saturday 02 October 2010 04:56:35 Saqeb Akhter wrote: >> Nope I already noticed that 1.8.8.3 was available so to that step, I >> am getting frequent disconnects though, it might have to do with >> NetworkManager doing background scanning so going to try and it it to >> stop doing that. > Channel changes (especially with HT) are more expensive with AR9170 > than AR9271 which features "fastcc" (fast channel change). > >> The NetGear driver on windows seems to ignore the WMM requirement >> looks like. > You can actually peek into the Windows' driver logic. > The code is available under drivers/staging/otus/(80211core) > AFAIK, it only checks if the HT IEs are all present. > >> Either way that's what the problem was, going to see if i >> can get this disconnect problem sorted out. > I thought "the new" NetworkManager is more intelligent and > doesn't schedule scans while the device is actively > transmitting/receiving data.
