Networkmanager takes a long time to connect to wifi after wake from suspend

[Corbin]

Networkmanager takes 10-15 seconds to connect to wifi after wake, as opposed to the normal 3-5 seconds.

This bug has already been fixed by the upstream maintainers of networkmanager- I hope to see the fix included in 21.04 before it's release. The fix can be found here
