Description Krzysztof Jurewicz 2015-05-21 08:49:09 UTC 
When connecting to ZTE MF28D router through WiFi on Thinkpad X1 Carbon (3rd generation) and Fedora 22, connection doesn’t seem to be fast and hangs after a while. Turning WiFi off and on resets the symptoms, so it helps only for a while. ZTE MF28D works well with an Android phone; the laptop works well with other WiFi routers.
