Poor Wi-fi since upgrade to Sky Max Full Fibre 150 from Ultrafast1

[MikeBN]

Since I changed from Ultrafast1 to Sky Max Full Fibre150 the Wi-fi signal is poor.  Previously it's range was fine and everything worked ok, but since being 'upsold' in recent contract renewals this is terrible, and sky won't sent an engineer.  I've moved the booster to several different locations, it's too far to sensibily run a cable between the Booster and the Hub.  Any suggestions?

If you have the WiFi Max subscription supplement (which presumably you do if you've been sent an initial Max booster pod) then you can insist Sky sends up to two more pods or an installer to fit them under the terms of the Enhanced Wall to Wall WiFi G.uarantee.
