I have been having problems with my WiFi connection on my DELL using Ubuntu as OS. I am new to the OS and trying to fix the issues I ended up un-installing the driver for the Network Controller.
description: Network controller product: Wireless 7260 vendor: Intel Corporation physical id: 0 bus info: pci@0000:08:00.0 version: 73 width: 64 bits clock: 33MHz
Above the details of the controller. Could you please tell me how to re-install the drivers and what to do after so it will work properly (it was constantly disconnecting)?
