Hi,
I've been with Virgin just over a month and am experiencing frequent drop offs in wifi to the point I where I can no longer take work calls unless I am in the same room as the router. I purchased a Netgear EX7700 extender but this did not help. Have now switched to an Eero Mesh network so the Hub (3.0) is in Modem route. This has improved things as I can now get wifi in all parts of my building (only 90sqm) but when I am in my office the wifi does continue to drop out for about 20 seconds at a time every 5-10 minutes. I have checked the RSSI for my laptop and it ranges between 30-50, I checked for any local issues and am not seeing anything pop up which has led me to believe its something to do with the line coming into my router/modem. Having looked at the forum I can see that my Dbmv Downstream is low and wonder whether that has something to do with it?

Your power levels look fine, and there's no indication of any interference.
Can you post the network log too? Maybe that will say something.
Is it possible to also create a BQM so that we can check the internet side of the router?

If the VM Hub is in Modem mode then it's not the source of the wifi issue. The power levels are within spec in any case.
You should get a wifi analyser app and check the wifi environment in the house. You may have to set the wifi bands and channels manually, as some band steering kit can cause small interruptions to wifi during the channel/band moves.

Thanks, I’m still getting continued drop offs in one room. The broadband analyser would suggest packet loss but I’m completely out of my depth here. If you have A look at the graph is it something I can resolve or Virgin?
