I can confirm the regression: my card is 02:00.0 Network controller: Broadcom Corporation BCM4306 802.11b/g Wireless LAN Controller (rev 02) and I'm running the kernel 2.6.22-11-386 on Gutsy I can confirm poor performance, I can reach only ~40KB traffic from a cople meters away from the AP. I cannot confirm the crash in restricted-manager, Infact i can download succesfully the firmware from the internet with restricted-manager (source http://xeve.de/down/wl_apsta.o) and the lights of my pcmcia card do light on, but restricted manager still ask for a firmware after a reboot, and I have to start over the process of enable firmware --> download the firmware from internet. I have filled a bug (Bug #139086) about this. Also I confirm a bug in restricted manager that prevents me from load a firmware using a local file either typing the path-to-file manually in the input box and trying to push the browse button. when launching restricted manager from a terminal and downloading the file from internet I receive this output from the terminal: filename : wl_apsta.o version : 3.130.20.0 MD5 : e08665c5c5b66beb9c3b2dd54aa80cb3 microcodes : 2 4 5 11 pcms : 4 5 microcode : 2 revision : 0x0127 patchlevel : 0x000e date : 2005-04-18 time : 02:36:27 microcode : 4 revision : 0x0127 patchlevel : 0x000e date : 2005-04-18 time : 02:36:27 microcode : 5 revision : 0x0127 patchlevel : 0x000e date : 2005-04-18 time : 02:36:27 microcode : 11 revision : 0x0127 patchlevel : 0x000e date : 2005-04-18 time : 02:36:27 Cannot open input file http://xeve.de/down/wl_apsta.o ===== this is DMESG output: [ 780.096000] ieee80211_crypt: registered algorithm 'NULL' [ 780.104000] ieee80211: 802.11 data/management/control stack, git-1.1.13 [ 780.104000] ieee80211: Copyright (C) 2004-2005 Intel Corporation
