Comment 19 for bug 708712

This problem is affecting my N150 too.

Rather than rebooting, I can get the wireless working by removing and reinserting the driver until it can connect. Run the following as root:

modprobe -r r8192e_pci; modprobe r8192e_pci

If it doesn't connect, check the network status in the bar at the top of the screen. If it says "device not connected", re-run the commands. Repeat until it connects. It seems to take 2-3 times on average for me.
