Enabling wireless causes system to hang

Asked by Cliff

I've installed Hardy Heron and everything is working fine except my wireless connection. The drivers appear to install correctly (Acer Aspire 1502LMi using Broadcom wireless card) but as soon as wireless is enabled the system hangs. After this has occurred the computer will hang during start up. The only way around this is to boot up in recovery mode and disable the wireless connection.

What log files do I need to attach in order for someone to help assess this problem? I don't want to go back to Windows, but need a wireless connection for my laptop otherwise I can only use it in the same room as my desktop, which pretty much defeats the purpose of it.

if you provide some additional information perhaps we can go further into your situation.

http://bcm43xx.berlios.de/ might be a start for information, this is what i get in my network interfaces file you should have similar.
cat /etc/network/interfaces
auto lo
iface lo inet loopback

I had to right clik on the knetwork manager and it displays the Address, statistics,and network information.
Which graphics driver are you using and graphics card ? Nvidia has been known to cause hangs with the solution being to downgrade
to vesa., if you are unsure of which driver use cat /etc/X11/xorg.conf |grep Driver to display drivers being used for your x system.

what if any errors show with the command dmesg you can add |grep error to display just lines with the word error. as dmesg |grep error

I reinstalled Hardy Heron from scratch (which is what I was running before). The only difference is that I did it in expert mode this time (as non-expert mode had a nasty habit of claiming the cpu was too hot, and bailing out on me when I did it before). Went smooth as clockwork, found the driver, automatically extracted the firmware and worked straight away. I'm a little mystified why I had so many problems last time.

I very much appreciate you taking the time to offer your help.
