rtl8723 wireless card

Hi,

I bought a new computer and the driver for the wifi card is from realtek -> rtl8723.

It is actually not compatible with the actual linux kernel and I have to change some parts of the configuration files to be able to compile it and load it into the kernel. However it seems that the connection is not stable with these tricks.

Does anyone knows if the driver will be added to the linux kernel in the future releases?

Bumping, got a friend with a brand spanking new laptop with rtl8723 & can't find any reference to any linux support?

Re: rtl8723 wireless card

Ok, the kernel doesn't know about this device. Try this as root, no guarantee whatsoever that it'll work:

modprobe rtl8912de
echo "10ec 8723" > /sys/bus/pci/drivers/rtl8192de/new_id

Try also with ce instead of de.

Then there's this: http://askubuntu.com/questions/139632/w … recognized <- There's links to a driver there, compiles up to kernel 3.3, the comments also contain a tweak to get it to compile with 3.4

Thanks guys, that askubuntu link seems to be working nicely.

Re: rtl8723 wireless card

Here is a few links about this matter (already gave before):
    Ask Ubuntu
    Ask Fedora

Drivers can be found here:
    Wifi Driver
    Bluetooth Driver

However it won't compile for kernel higher than the 3.3. Solution to make it work is given in the upper link.

I am experiencing the "wlan0: deauthenticating from MAC by local choice (reason=3)" problem. I don't know if it's linked with the tweak to compile the kernel module.
