Dear List, For the past 7-10 days I been experiencing a persistent problem with wifi connections on my Lenovo T440s after using F22 for 12 months in the machine without problem. The wifi connection is made just fine with my router and I initially have connectivity. After a few minutes though the connection will become dead (eventually the gnome status area icon will show a ? but only if I leave it long enough). When I try to visit a new website in Chrome it displays "Resolving Host" in the status pop-up. I was just starting to run a dfn upgrade and I saw: Error: Failed to synchronize cache for repo 'updates' from 'https://mirrors.fedoraproject.org/metalink?repo=updates-released-f22&arch=x86_64': Cannot prepare internal mirrorlist: Curl error (6): Couldn't resolve host name for https://mirrors.fedoraproject.org/metalink?repo=updates-released-f22&arch=x86_64 [Could not resolve host: mirrors.fedoraproject.org] If I turn the wifi of and back on again (either via the physical key on the keyboad Fn-F8, or via the gnome3 wifi/status tool in the top right of the desktop) the connection comes up fine and I have connectivity again for a few minutes and then the cycle repeats again I've tried changing DNS servers to say Googles servers to rule out an issue with my router/ISP DNS but to no avail. I have numerous other devices (all Android) in the house connecting to the same wifi router and they are not experiencing any connection problems at all. I'm running currently Linux 4.4.11-200.fc22.x86_64, but see the same problem on 4.4.10 and 4.4.9. I also have: NetworkManager.x86_64 1:1.0.10-3.fc22 @updates installed. I'm not really sure how to troubleshoot this problem or what to try to resolve it short of installing F24 and risking using the beta for a couple of weeks. I'd appreciate greatly any insights you might have or suggestions as to what to look at to track down the source of the problem or provide more information that you might require to diagnose what is going on.
