I'm on my college network and the internet stops working after some time even though the WiFi remains connected. To make it work again, I have to disconnect and reconnect, after which it works for a while before the problem reoccurs. This problem does not happen on Windows 10.

I have several suggestions that may help connectivity.

First, in your scan results, we see no fewer than six access points with the same name. In your wireless info, we see that your wireless device drops one instance and roams to another, looking for a better signal:

[ 8158.059001] wlp2s0: disconnect from AP <MAC 'ION@17th-Block' [AC1]> for new auth to <MAC 'ION@17th-Block' [AC8]>
[ 8158.064564] wlp2s0: authenticate with <MAC 'ION@17th-Block' [AC8]>
[ 8158.067518] wlp2s0: send auth to <MAC 'ION@17th-Block' [AC8]> (try 1/3)
[ 8158.070584] wlp2s0: authenticated

I suggest that you bind your wireless connection to the strongest of the nearby instances in Network Manager using the method I describe here: Ubuntu connect drops. Worked for a while then started dropping again

Next, I recommend that you turn off power saving in Network Manager; from the terminal:

sudo sed -i 's/3/2/' /etc/NetworkManager/conf.d/*

Finally, set your regulatory domain explicitly. Check yours:

sudo iw reg get

If you get 00, that is a one-size-maybe-fits-all setting. Find yours here: http://en.wikipedia.org/wiki/ISO_3166-1_alpha-2 Then set it temporarily:

sudo iw reg set IS

Of course, substitute your country code if not Iceland. Set it permanently:

sudo nano /etc/default/crda

Change the last line to read:

REGDOMAIN=IS

Proofread carefully, save (Ctrl+o followed by Enter) and close (Ctrl+x) the text editor.

Reboot and tell us if there is any improvement.
