My wireless connection keeps dropping after about 10 minutes. It seems to happen when I'm sshed into the machine, but it could just be coincidence.
Some of the things I've tried are turning off N on the router and adding these and these suggestions to rc.local. Also, I was getting No probe response ... after 500ms, disconnecting previously (like here).
I also tried to install the driver mentioned here, but compiling it failed for me.
Any help would be appreciated!
Here's the output of wireless_script:
