[Pkg-utopia-maintainers] Bug#933930: network-manager: WiFi signal excellent, but won't connect to internet

[Dean Chia]

Package: network-manager
Version: 1.20.0-1
Followup-For: Bug #933930

Dear Maintainer,

AFAIK, after upgrading to Linux 5 and/or when I upgraded to 1.20.0-1 network-manager, my wifi becomes spotty.

The signal itself is fine (and my smartphone's wifi is just fine), but suddenly all my web pages hang, and 
I cannot connect to the internet. I can usually regain internet functionality by going to WiFi settings and
reselecting the same SSID to refresh or reconnect. This leads me to another few minutes of perfectly good
WiFi until it chooses to break again. I am using 5GHz Wireless AC. Previous to this, everything was working
fine perfectly 100% of the time. On occasion, turning off WiFi and turning it on would get things working,
but not 100% of the time. I have tried multiple times to "aptitude reinstall network-manager network-manager-gnome".

Thank you! I have a ThinkPad X1 Carbon 3rd Gen, with (from lspci:)
Network controller: Intel Corporation Wireless 7265 (rev 59)
