Wifi only working in one room

[HelenStanley]

We have super fast broadband 500, which has been working fine , but WiFi has suddenly stopped working unless you are right by the router. A couple of phones working in the kitchen, one room away but with slow speed, sky glass in that room seems fine.

Have tried rebooting everything,  sky test says everything fine in main room but does say problems with WiFi in rest of the house.

And of course the sky boot is totally useless. 

We have sky boost but Internet fine coming into the house , problem seems to be the router.

@HelenStanley  If you have Sky boost you can ask Sky to send you out a booster, just give them a call on your landline by dialiing 150 on your handset and listen through the voice prompts.

Thanks I will have to ring them , thing is up until this week we were getting strong signal though out the house, even yesterday morning I was get plenty of WiFi signal in the kitchen., I think it must be the router playing up.

Many for your reply
