DataToBiz’s Hack:

Enable auto login so that wifi never loses its connectivity on ssh. Here is how to make it happen:

sudo nano /etc/gdm3/custom.conf

In this file, uncomment the following:
I. AutomaticLoginEnable = true
II. AutomaticLogin = user // put your user name here e.g. jetson

After following the above 10 steps, Edimax module will never drop the connection.
