Which p54 firmware do you use? (It "must" be 2.7.0.0 for pci/cardbus) 2. What's your "average" txrate and Link Signal Level / Link Quality with and without the patches. (see iwconfig) 3. what brand/type of AP do you have? -> what does the beacon frame look like? (or: if you don't have a wlan sniffer / monitor, just run: iwlist wlanX scan ) 4. Can you recompile the mac80211 layer with debug options and look for something like ethX: STA XX:YY:ZZ:AA:BB:CC Average rate: VVV ... in your syslogs? 5. are they any suspicious dmesg outputs when the "network" stops/dies?
