The first reboot of the local installed, WLAN was turned on automatically again. On my Acer TravalMate 4650 in live environment, the internal blue-tooth suddenly worked for the first time ever(Windows XP was not working with the internal bluetooth so I used a USB-extension instead), but WLAN not, even with the driver installed and started. Had that as well on the live environment, but a little different!!! Sudo modprobe -r rtl8188ee & sudo modprobe rtl8188ee If the message logs say you need firmware: dmesg | grep rtl When Update Manager installs a later linux-image, after reboot, re-compile: cd ~/Desktop/backports-3.11-rc3-1/ You will have compiled the driver for your currently running kernel only. I suggest you download this to your desktop: Right-click it and select 'Extract Here.' Now open a terminal and do: cd ~/Desktop/backports-3.11-rc3-1/ Please get a temporary wired ethernet connection and do: sudo apt-get install linux-headers-generic build-essential

If so, you can compile this driver in 13.04. Verify your device with the terminal command: lspci -nn

Crappy quality control, but the problem was fixed for ten bucks which was cheaper than shipping it back and less hassle than doing a factory reset (which wouldn't have fixed the problem anyway) The little Edimax USB wireless adapter runs about $10 on Amazon and it fixed my problem.If this is your device, it is covered by the very new driver rtl8188ee: Network controller : Realtek Semiconductor Co., Ltd. I suspect that some of the Satellite models have a defective built-in wifi chip and sometimes ethernet chip too. As soon as I went to the USB adapter, my download speed jumped to 45mbps, which for a wireless connection through a concrete wall is respectable. My download speed prior to doing this was around 3mbps. I already had an inexpensive little USB adapter, (part of a workaround on that old dog VISTA) so in a last ditch effort, I went in and disabled the network adapter and popped in the usb adapter. Like you, I assumed it wasn't the adapter, because wired or wireless made no difference, however, in my case it WAS the adapter. I did EVERYTHING I could think of or read in forums to try to fix it, and nothing worked. I had the same problem with my new Toshiba Satellite.
