3. No other boosters or mesh 

4. software. Q270.000.08.00L (5u193c0)

5. No noise. But my connection to the hub lasts a few minutes at most and then Says not connected and there is a problem. 

6. I do not have the fan whirring issue. I just have no internet connection. I have tried all the fixes in this thread. 

7. Just the there is a problem with your network screen.
