I have installed Ubuntu 17.04 on my Lenovo Thinkpad. I can connect to most Wifi networks except for one particular from a Netgear router. I tried the fix mentioned here but it did not help.

When I try to connect to said WiFi with my phone, it works...

Print from sudo lshw -class network:

*-network

    If you can connect to all but one then the linked answer isn't applicable. First of all, you need to check that router's wireless encryption settings and make sure it's WPA2-AES only and, quoting from @chili555, not any WPA/WPA2 mixed mode and certainly not TKIP. –  Aug 01 '17 at 19:43
  • Encryption is WPA2-AES, that is not the problem. The router btw is a NetGear ProSafe 802.11 G, if that helps... – laerbich Aug 02 '17 at 19:34
  • Indeed it helps. I suspect that router is too old. Usually I would suggest looking for firmware updates but not sure you'll find any. –  Aug 02 '17 at 20:20
  • Sorry @MichaelBay i forgot to answer. You were correct, I use another router now and everything works fine. – laerbich Aug 09 '17 at 09:39
