Low Quality Wifi with TL-WDN3200(N600)

Question

Recently I needed to install Ubuntu on my machine. The problem is that I'm getting a low-quality Wi-fi signal.

I'm using a "plug and play" wi-fi connector from TP-LINK: TL-WDN3200(N600).

How can I improve this?

Answer 1

Miraculously, a user from omgubuntu.co.uk had written a comment in one of their articles announcing the release of 17.04 that fixed this issue. The comment is as follows:

wifi and networkmanager

The new NetworkManager release 1.4.0 adds new features to change the current MAC address of your Ethernet or Wi-Fi card (spoofing/cloning). As a debian "sid" user i understand that being on bleeding edge, sometimes new features and configs can be Incompatible with my machine hardware!!! Now being a ubuntu user i can see that Ubuntu is losing his "user friendly" name and no more care for desktop users! This was an unacceptable default config on Ubuntu's best days! Ubuntu haters and criticists must be happy now!

Edit the /etc/NetworkManager/NetworkManager.conf file

And add:

[device]
wifi.scan-rand-mac-address=no

Restart the networkmanager service and use your wireless connection :)"

This worked for me.

Open a Terminal and enter:

sudo dpkg-reconfigure resolvconf
echo "options rt2800usb nohwcrypt=y" | sudo tee /etc/modprobe.d/rt2800usb.conf 
sudo modprobe -rfv rt2800usb
sudo modprobe -v rt2800usb
sudo service network-manager restart
