Hello @Harry02111
Wifi coverage is one of the biggest issues reported across all broadband suppliers, with some routers better than others. The Sky Max (white) router seems particularly prone to poor performance from what i've read on here, although I have no experience of this as we still have the black one.
You have a few options which all come with a cost:-
1. Loan/rent up to three boosters from Sky. Again, I have no experience of this but believe that they will send you the first one for self installation but then if you still have problems you have to contact them and an engineer will visit to optimise your network and add up to 2 more boosters if necessary.
2. Use home plugs on your mains circuit to connect devices to your router by ethernet cable or to link your own wifi hotspot/booster device upstairs. This would require a spare mains socket near the router and in the target room.
3. Invest in some Mesh devices and create your own Mesh wifi network, disabling wifi on the Sky router. You will need at lest two devices and possibly more - one near the router and one (or more) placed somewhere else near enough to wirelessly connect to each other. Again power sockets are required for each device.
We live in a bungalow and struggled with wifi coverage towards the rear of the property as the broadband comes in at the front and I have no easy way of re-locating the router more centrally. So 3 or 4 years ago when we were still with TalkTalk I invested in my own Mesh hardware that supplied strong wifi across all rooms, the back patio/garden and even the car parked out front.
This has worked flawlessly with both TalkTalk and now Sky since we changed supplier over a year ago. The bonus is that it gives you control over your network and makes moving supplier/provider very easy as no need to change your wifi SSID/Name and password.
I went with Amazon Eeros but there are quite a few Mesh suppliers out there which do not need to cost the earth and so that would be my recommendation.
I hope that you find a solution that works for you.
