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)?

Please do:

sudo modprobe iwlwifi

did it turn back on? if so do:

echo "options iwlwifi 11n_disable=1" | sudo tee /etc/modprobe.d/iwlwifi.conf
sudo modprobe -rfv iwldvm
sudo modprobe -rfv iwlwifi
sudo modprobe -v iwldvm
sudo modprobe -v iwlwifi

if not tell us how you uninstalled the driver.
