So I've recently upgraded my broadband to Fibre 2 and the connection speed is fine in most places and does work usually, but within my room I feel as if the network is slower or something, so I've been looking to buy a wifi-disc but I don't see any option to unless I get a whole new bundle. Is it possible to buy one seperately and pay it for monthly or do I have to start a whole new package and purchase the Complete wifi deal? Please let me know, thanks.
Or you could consider powerline adapters such as this one, about £65 at Amazon

Welcome to this user forum for BT Residential phone and broadband customers.
An individual disc is very expensive to buy, £100 and only works with the BT Smart Hub 2.
If its just an issue in one room, then a wireless hotspot is a much cheaper option.
As @licquorice has said.
