AC1600 not connecting to 5ghz network

[T_Elderkin]

I am running windows 10 and am having trouble with my wireless wifi adapter not connecting to my 5ghz network. connects to the 2.4ghz just fine.

any else have this problem or know a fix?

"Not connecting" doesn't give us much to go on.

Does it see 5 GHz?

What happens when you try to connect?

Do other things connect OK to 5 GHz?

What does the wifi come from?

What is the adapter plugged into?

I welcome the questions. would love to get it fixed.

It does see the 5ghz

after typing in password it connects for ~10-20 and then says cannot connect to network 

all my other devices connect fine so it is probably the adapter 

Wifi comes from in house router 

would it be a driver problem?

Alternatively, it could be the device that the adapter is connecting to the wifi.

If it really does connect, and then after 20 seconds it throws an error, I would check the network's properties. If this is a Windows thing, then the Network troubleshooter might help.

The adapter may be connecting to the wifi, but the PC (?) is not connecting to the network.
