Virgina have moved us from a Hub 3 to a Hub 4 which is a self install. Its now up and running and I split the 2.4 and 5 ghz so Sky Q can connect to 2.4 only (this is what the vigin installer recommended when he put the Hub 3 in)

The Deco P9 is showing as connect but no internet. Does anyone know what I need to get this reolved as I cant find anything on the internet.

The Hub 4 is in Enable Route Mode

Smart Channel Optimization is enabled 

Wireless MAC Filtering is disabled

DCHPv4 Server is enabled

UpnP is enables

Any ideas?
