Router not allowing connection to devices on local network

No joy.As I say I can see my devices listed under “not connected”.

I wish there was a “connect” option,but sadly there isn’t.

Try temporarily turning off the 5Ghz wireless and see if everything connects then.

I wouldn't put to much faith in the "My Network" part of the hub manager, it's flaky to say the least. 

Try pinging the devices and see if they answer
