Updating Driver for Wifi Adapter in Ubuntu

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

Since the time I started using external Wi-Fi Adapter, the Wi-Fi connections lost even though the symbol says connected, I have looked into several suggestions but that doesn’t work because I failed to figure out my exact mistake; Yesterday only I figured out mistake, those days when I installed Ubuntu 16.04 I thought it may be due to some issues related to particular version, but when I tried through try Ubuntu it is same, and Finally when I tried with Ubuntu 14.04; Thereafter I figured out the Issue is with Updating device driver :smile:.

Check this code (Note this will work for 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
