I just switched a PC to Ubuntu 16.04 and I'm getting some odd wireless network behaviour.
When I try to connect to my wireless, I have a brief connection followed by a disconnect. The thing is that every other device on my network also gets booted off (XBox360, Windows 10 laptop, 2 android phones). I can still see the network as available, but it won't establish a steady connection and my other devices won't connect at all.
I've tried to ping my IP address and I get one connection, followed by an endless series of messages saying the network could not be found, or that it could not connect.
Here are the results of my "lshw -c network"

And here's the info on my "lspci -nnk | grep -iA2 -net"

This may also be of interest:
- I'm connecting via a TP-Link (Model: TL-WN822N) Adapter;
- When I disconnect my wi-fi on my PC, my other devices re-connect to the network almost instantly (confirming for me that the problem is with Ubuntu);
- I can't connect via Ethernet because the only phone jack in my apartment is in another room and I don't have a cord long enough to reach the PC. My Ethernet cable is currently connected to my XBox, and there is no change in behaviour if my XBox is turned off);
- I tried using this wireless script, but nothing happens when I run it (regardless of whether the wireless is connected or not).
I apologize if this question has already been asked and answered, but I didn't see a similar situation where other household devices get booted off.
