If you have a Toshiba laptop, there’s a good chance it has a Realtek RTL8191SE Wireless LAN 802.11n PCI-E NIC or some minor variation of same. Realtek apparently doesn’t make it very easy to find drivers for linux for this card – the person who posted the driver said he got it from Realtek, and I don’t have any real reason to doubt that. It works for me, in any case. Here are the steps I took to be able to use WiFi on my Toshiba Satellite P505. YMMV, so feel free to give a thorough read of the problem and solutions available at the Ubuntu help/bug forums. The driver tarball is available to download from that thread. rtl8192se_linux_2.6.0010.1012.2009.tar.gz (1.3 MiB, application/x-tar)
only load the driver module to kernel and start up nic.
1. Build up the drivers from the source code
make
2. Copy firmware to /lib/firmware/ or /lib/firmware/(KERNEL_VERSION)/
cp -rf firmware/RTL8192SE /lib/firmware
or
cp -rf firmware/RTL8192SE /lib/firmware/(KERNEL_VERSION)
Note: This depends on whether (KERNEL_VERSION) subdirectory exists under /lib/firmware3. Load driver module to kernel and start up nic.
./wlan0up
And now back to writing.
