Well, this one did not solve the problem but it certainly did help! It took me some effort to make it bug again... I worked fine for 5 minutes, I was able to browse the web and such. I was also removed/inserted the module a few times. It finally crashed when I tried to transfert a file of several MB. Maybe the 200ms delay should be less (or more?) I think I will try to change it for some arbitrary number, just to see if it helps. - William [ 393.039477] b43-phy1: Broadcom 4312 WLAN found (core revision 15) [ 393.130317] b43-phy1 debug: Found PHY: Analog 6, Type 5, Revision 1 [ 393.130385] b43-phy1 debug: Found Radio: Manuf 0x17F, Version 0x2062, Revision 2 [ 393.192506] phy1: Selected rate control algorithm 'minstrel' [ 393.193173] Registered led device: b43-phy1::tx [ 393.193241] Registered led device: b43-phy1::rx [ 393.193309] Registered led device: b43-phy1::radio [ 393.193674] Broadcom 43xx driver loaded [ Features: PLS, Firmware-ID: FW13 ] [ 421.362952] b43 ssb0:0: firmware: requesting b43/ucode15.fw [ 421.381454] b43 ssb0:0: firmware: requesting b43/lp0initvals15.fw [ 421.392366] b43 ssb0:0: firmware: requesting b43/lp0bsinitvals15.fw [ 421.540362] b43-phy1: Loading firmware version 410.2160 (2007-05-26 15:32:10) [ 421.542820] b43-phy1 debug: b2062: Using crystal tab entry 19200 kHz.
