I see, the point is that wireless-testing already contains latest iwlwifi driver much newer then 1.2.25. so no need for patching just compile the kernel. > As another data point, it appears the iwl4965 operates at full speed > using a more up-to-date Wireless Access Point such as the > Cisco/Linksys WAP4400N. I'm not so familiar with the Linksys-B AP. Is it B-only AP? I suspect there is a problem in rate scaling and we are going beyond the CCK rates which B-only AP cannot hear. but this is only shutting to darkness, need to reproduce. I'm not sure if you have a sniffer but capture of traffic would be very useful. > Given that input, is there somewhere else we could look? I will > update the bug record with these findings. Can you put exact version of the AP to your bug description, including software/firmware version. Thanks Tomas
