All facets of problem recreated with 8.10 Intrepid release: - Native driver for bcm4306 rev 2 wifi (ssb/b43legacy) is _severely_ crippled. It averages 75k bytes per second with many stalls as tested with scp. - Ndiswrapper/bcmwl5 (built in Broadcom 4306 rev 2 hardware) will not connect to a WIfi with WPA2 encrytion (this works in 7.10 Gutsy) - Ndiswrapper/bcmwl5 will connect to an open WIfi with no encryption (with excellent 2.7 mbytes/second transfer speed) - Ndiswrapper/rt2860 (Rtlink 2860 in an Airlink AWLC6080 pccard) will connect to a Wifi with WPA2 encryption (with excellent 2.7 mbytes/second transfer speed)
