I started on Elementary OS, then moved to Ubuntu 16 LTS and now I am on Ubuntu 17.04. Using a Belkin Wifi USB dongle, the connection drops regularly on all OSs with my hardware. The only solution is either to remove and re-insert the dongle or to disconnect and reconnect to the network. I already tried a few other answers here on Ask Ubuntu but none of them worked. Like disabling mac address randomisation and updating to the latest version.

Here is some system info.

  • Have you tried disabling power management? Check if it's enabled with iwconfig. Also, to avoid endless back and forth soliciting more info, check out askubuntu.com/questions/425155/…. – mikewhatever Nov 3 '17 at 9:37
  • I updated the answer with the Wifi data. Power management seems to be off: Power Management:off – wout Nov 3 '17 at 10:08
  • At your router change the wireless encryption settings to WPA2-AES. Always avoid mixed modes and especially TKIP. Also be realistic about your hardware capabilities: You're using an old b/g only router. – user692175 Nov 3 '17 at 10:17
  • And your wireless script results show that you're using 17.04, not 17.10. support for 17.04 will end in a few months. – user692175 Nov 3 '17 at 10:19
  • Unfortunately I don't have access to the router. Also, none of my other devices (MacBook, iMac, iPad, iPhones) are experiencing any issues. – wout Nov 3 '17 at 10:21

Upgrading to Ubuntu 17.10 solved the Wifi problem as well as a lot of other issues. Now I no longer need the dongle as the built-in Wifi is working as it should. Both the dongle and the built-in Wifi work flawlessly.
