Hi John
I appreciate your advice, but I work in IT and understand WiFi and the steps to take.
We have a hub 5, it's been in the same spot for the last 4 years (approx), it's no where near any water, we don't have a fish tank, we don't have cordless phones, it's no where near a TV as it's in an upstairs hallway where it's always been.
I did mention that I can be sat right next to the hub and get speeds as as low as 30 - 40 Mbps.
I've already got and been using the virgin connect app, as long as the speeds are higher than 30Mbps it's says "all looks great"
I've used the virgin speed tool via accessing the router settings using an iPad pro which in the post got decent WiFi speeds before the upgrade and I'm sat next to the hub and it tells me to move closer to the hub as the connection strength is low. I can't get any closer.
There have been times if I'm within sight of the hub a couple of meters away that I get WiFi speeds of 500, but only a few times.
