yeah, a lot of the edimax - Hawking usb wlifi's are opensouorce. Question - do you have non-free enabled in your /etc/apt/sources .list ?
What is your network-manager? wicd, nm-cl,i network-manager-blah connman, direct configuration of the systemd files? I use connman myself/
What flavour of sparky are you using.
connman and ofono for the cell phone. and a bluetooh daemon should be sufficient IF you choose to go connman. Gui's are available. Network-manager-foo should have all you need and in a gui - BUT I have no idea how NM is doing at this time with the libstdc++6 transition.
Note - if you are using the kde flavour of sparky, you have entered one of the most chaotic transitions in history, KF5 transition was started just prior to the libstdc++6 transition.
sudo journalctl -b -0 will give you some good logs. You can pipe via grep for searches - i.e. sudo journalctl -b -0 | grep network
If asking for help on any debian-irc don't mention sparky. If you are not sure about your /etc/apt/sources.list - post it here.
I am leaving on holidays, see mum dad. Peace out
