Just had my Router changed to a Hub 3.0 because of a fault on my old router.
Immediately the range of the WiFi is terrible.
Just spoke to an Techy who actually knew his stuff and ordered me a free booster.
He even said to save the delivery charge I can pick up my free wired booster on Tues locally in a little newsagent round the corner.
Think the Wifi Range issue on the Hub 3.0 is a massive one.
I think is a Netgear one but will let you know.
