Here’s quick fix for annoyed users with Realtek RTL8192SU WiFi chipsets wanting some WiFi…

I just bought a new Wi-Fi dongle for my netbook (due to woes with the Broadcom card inside, but that’s a whole other post) and although my no-name budget £10 dongle boasted ‘Linux support’ on the packaging I was a mite miffed to find it incapable of mustering even a faint signal of anything when plugged into my Ubuntu 10.10-running device.

Doubly annoying given it works flawlessly in Natty…

So what’s up?

After Googling around I came up on a bug report titledPlease include firmware for RTL8192SU. The response was illuminating: –

“On 10.04 & 10.10 the firmware is already there but its in the wrong location.”

The solution to is open a terminal and pop in the following command: –

sudo cp -R /lib/firmware/RTL8192SE /lib/firmware/RTL8192SU

Reboot and, fingers crossed, your dongle will be up and receiving – certainly worked for me!

Need to find out what chipset your dongle uses? Plug it in, open a terminal and type ‘lsusb’. All connected USB devices will be listed.
