Weird problem with Android tv box -- looking for clues?

[Jingthing]

OK I had a well used Android box just fritz out on me the other day. There was something on the screen about HDMI and then it went kaput. No reponse at all to powering up anymore so decided it was game over on that one.

 

So ordered a new box and found it impossible to set up. 

It won't accept internet by LAN or wireless but I know they work as they did for the old box and the wireless works directly to the TV.

I then tried connecting from a mobile hotspot -- just the same the Android box could not be connected to the internet.

It does see the wireless sources so can choose and enter correct pwd but just always fails to connect.

So I'm thinking either the box is defective or there is something very weird with my setup.

I'm sending the box back and it will be either fixed or replaced, but I'm kind of expecting to get a new box that they say will work and find the same problem.

I had considered it might be about my router settings which I haven't looked at but again the router does work for the tv and did work for years on the old box.

I've tried all the usual troubleshooting things to no avail but I did buy a new lan cable which I haven't tried yet.

Any ideas?

If you specify the box you have and its supposed features someone may be able to offer some suggestions. 

 

Do you have the same issues with both 2.5GHz and 5GHz?

Has the unit been paired through Bluetooth. Sometimes I can't connect without pairing first
