I have an Intel Wireless 7260 Wi-Fi adapter with very bad Wi-Fi reception. So I thought it might be a driver issue. I tried Ndiswrapper and installed a driver I found for Windows. After a reboot, the "Enable WiFi" checkbox under the "Enable Networking" one in the network widget, had disappeared. I did completely remove ndiswrapper in Synaptics. After a reboot, it was not fixed.
lshw -C network, I found that my network interface was listed as
*-network UNCLAIMED. This seems to mean that no driver was installed for the interface.
How to re-enable or reinstall the Linux drivers for my Wi-Fi interface?
This is the output of
$ tail /etc/modprobe.d/blacklist.conf # nice pulseaudio bing (Ubuntu: #77010) blacklist pcspkr # EDAC driver for amd76x clashes with the agp driver preventing the aperture # from being initialised (Ubuntu: #297750). Blacklist so that the driver # continues to build and is installable for the few cases where its # really needed. blacklist amd76x_edac blacklist ndiswrapper
The last line I added myself as suggested by a forum post I found somewhere. It shouldn't cause problems since ndiswrapper is already completely uninstalled.
