@Jolene3 gaming overceven goid wifi is not a good idea if youbare struggling to connect to the hub you definitely need some extra kit to get the data into thosecrooms. For most uses an extender or boister can work but for anything other than casual gaming they are pretty useless.
Assuming running ethernet cables is impossible your choices are to use powerline networking adapters which you buy in kits they usecyour home's mains wiring to carrybtge dats from the hub to the bedrooms or a proper whole home mesh wifi setup which are not cheap. Sky sell their own as Wifi Max which costs £7.50 a month which can havecupmto 3 extender pods if they an engineer agrees they are needed.
