PC disconnects from internet (Yes me too) Hub 3.0

As with the other posts here my PC is being constantly disconnected from the internet. Pings fail, webpages cannot be resolved (ERR_NAME_NOT_RESOLVED), WIFI equipment cannot connect..  Hub test shows (a brief  example)

9The device has low signal strength, please move it closer to Chromecast.
10The device has low signal strength, please move it closer to Google-Home-Mini.
11The device has low signal strength, please move it closer to ...

The list goes on.......

13Your broadband connection is down.

These items are within 6 feet of the router.

This has being going on for months, I have checked cables reset and reset and reset..So sick of it.

Looks like lowering the power levels won't fix the same problem for me.

Does a yellow triangle symbol pop up when it disconnects?

On the PC?, Occasionally, depends on how long it goes off for.

Re: PC disconnects from internet (Yes me too) Hub 3.0

Hi  steveterry,

Your connection looks okay from this end, with both Hub stats and local circuit reporting back in good shape.

Are the drop outs happening just on wireless or are wired connections affected too, is there any change in the Hub lights when connectivity is lost and does this affect all connected devices simultaneously?

Drop us a few more details and we'll be able to assist further.

Kind rgds

Re: PC disconnects from internet (Yes me too) Hub 3.0

The drop outs happen on both wireless and cabled. I have now connected in modem mode and this has stopped the WIFI disconnects so clearly it is a problem with the Hub 3 router. The wired connection still drops.
