Updating Driver for Wifi Adapter in Ubuntu

These code blocks are obtained from Stackoverflow; this particular blog post is to emphasize a little more about the issues related to that.

Since the time I started using an external Wi-Fi Adapter, the Wi-Fi connections were lost even though the symbol said connected. I looked into several suggestions, but they didn’t work because I failed to figure out my exact mistake; it was only yesterday that I figured out the mistake. Back when I installed Ubuntu 16.04, I thought it may have been due to some issues related to the particular version, but when I tried through Try Ubuntu it was the same, and finally, when I tried with Ubuntu 14.04, I figured out that the issue was with updating the device driver :smile:.

Check this code (note this will work for a Realtek based Wi-Fi Adapter since in the third line we can see the phrase rtl8192cu-dkms). So don’t try this for other cases :smile:.

Ubuntu 14.04

sudo add-apt-repository ppa:hanipouspilot/rtlwifi
sudo apt-get update
sudo apt-get install rtl8192cu-dkms linux-firmware

Ubuntu 16.04

sudo add-apt-repository ppa:hanipouspilot/rtlwifi
sudo apt-get update
sudo apt-get install rtl8192eu-dkms
