I claim absolutely no credit for this, and I apologise if this is a duplicate of instructions contained within other posts on this forum, but hopefully this will save someone from despair at some point. Instructions are on a blog post here - Captcha
This blog looks pretty decent, worth a lunchtime read
Ahh, nice … larry finger to the rescue again … dude deserves a Linux Wireless Knighthood
We need to get this info to donwatson … I think his onboard card was one of those … and that’s certainly his symptoms.
IIRC, we tried the driver config settings but we didn’t try compiling the driver from larry finger
The instructions for compiling the Larry Finger (lwfinger) driver on that link are no longer valid … he’s moved all the realtek drivers to a central git repo.
they’d now need to read
sudo apt-get install linux-headers-generic build-essential git
git clone http://github.com/lwfinger/rtlwifi_new
sudo make install
which builds and installs the drivers for
rtl8192ce, rtl8192se, rtl8192de, rtl8188ee, rtl8192ee, rtl8723ae, rtl8723be, and rtl8821ae
all in one go
