Re: NM drops WPA connection

[Marcello Musso <musso physics utexas edu>]

Thanks Larry,

I do the regular Ubuntu updates and distro upgrades, therefore much 
software is changed. I cannot tell when the issue started because I have 
WPA at work and I don't bring my laptop often.
Also, being at work, I cannot do anything to the access point. But how 
could this stop my connection after a few minutes? Other people use it 
without problems.

As for using the Windows driver, although I dislike MS too, I always had a 
better experience with ndiswrapper over bcm43xx.
I also have seen a few threads on the Ubuntu forums about this or similar 
problems.
