Network Manager not allowing to connect to 5 Ghz Network

I upgraded my system recently and found that network manager is not allowing me to connect to 5 Ghz network. If i connect my 2.5 Ghz adapter it connects automatically.

Here is the relevant aoutput

Does the previous solution no longer work?

No, its not working. It is just asking for password

Which package is this driver from? If it's a DKMS driver, have you rebuilt it? Have you tried with a different kernel, e.g. linux-lts?

Please also think about what you could try rather than relying on someone to provide a copy-paste solution. Then, you can feed back and say what you have tried and what does - or doesn't - work.

Ok Jonathon

I'm kind of with Jonathon in that you haven't provided any background info on this. You never even mentioned your prior related thread on this issue (big time waster).

That said I would try only allowing 5 GHz connections through your routers setup and also through Network Manager to see if you can force a 5GHz connection.

Oh, also, remove and re-add the connection.
