OK, sorry for the confusion, iwl4965 was not enabled by default, and I assumed it was not there. I've completed the test, wireless-testing kernel from two days ago does not resolve the slow wireless connection. I will update the bug report with this data. > > > > 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.

It's an old Wireless-B unit, so I can only guess it's 'B' only. It is a Linksys WAP11 Ver. 2.0 Firmware: v2.05, Aug. 04, 2003. Unfortunately, the hotels and coffee shops around the country are filled with these units, and I travel for a living, so I'm holding out hopes for a solution, and stand ready to help in any way I can. Again, I will update the bug report with this data. Regards, Chris
