Had the wireless working on my Dell Studio 15 for months now (Ubuntu 10.04 64bit, now 10.10 64bit). But I shut the lid this morning, which put the machine to sleep; when I openend it again the wireless would no longer connect to anything :'(

I rebooted the machine, but that didn't help. I then did ifconfig eth1 {down,up}, but that didn't help, then I did iwconfig eth1 power {down,on}, but that didn't work.

So I uninstalled the wireless driver (Broadcom STA) from additional drivers (reboot in the middle), but it still won't work anymore!!

This is the trace from daemon.log, looks like it is a driver issue?

Anyone seen this, or know how I can get around this issue? It had been working fine up until now?! Even ran update-manager, but there wasn't any changes to the wireless drivers (or any related networking areas). Running the most up-to-date version of 10.10 x64.

My android phone and other devices are still working on the wireless.
