Hi everyone, fairly new to Linux. I've installed Ubuntu 12.04 on my Asus N76VZ, and I'm having issues with the wireless connection dropping every few minutes. I can disconnect and reconnect and it will then work again.

I've already tried disabling IPV6, but that doesn't seem to do anything for me.
