Still can't get past about 30KB download speeds. Access point is Linksys Wireless-B - other machines on same network can get 10-15 times that speed w/ a variety of adapters. I've enabled logging in kernel config, but logs don't reveal anything unusual: $ dmesg | grep iwl4965 [ 14.296000] iwl4965: Intel(R) Wireless WiFi Link 4965AGN driver for Linux, 1.2.25ds ** [ 14.296000] iwl4965: Copyright(c) 2003-2007 Intel Corporation [ 14.296000] iwl4965: Detected Intel Wireless WiFi Link 4965AGN [ 14.700000] iwl4965: Tunable channels: 11 802.11bg, 13 802.11a channels ** (also tried 1.1.0, 1.2.0ds) $ iwconfig wlan0 wlan0 IEEE 802.11g ESSID:"" Mode:Managed Frequency:2.412 GHz Access Point: 00:0C:41:66:A3:F9 Retry min limit:7 RTS thr:off Fragment thr=2346 B Link Quality=55/100 Signal level=-45 dBm Noise level=-70 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:0 Missed beacon:0 $ uname -a Linux brutus2 2.6.22-14-generic #1 SMP Sun Oct 14 23:05:12 GMT 2007 i686 GNU/Linux (Gutsy Gibbons stock kernel) After a couple days of searching (Google, bughost, etc) I've noticed others with similar problems, but never came across a resolution. Bug 1481 is similar, though not exact. Performance is acceptable under WinXP (400KB+) Is this a configuration issue or a genuine bug? Any help would be greatly appreciated. I'll be happy to enter a bug report, and assist in any way I can (testing, etc) to help reach a resolution. -Chris Hallinan -- Life is like Linux - it never stands still.
