I'll be honest, I've always been a bit dubious as to whether you need to fit these to every phone socket, but have always done so.
A couple of months ago I upgraded to a super fast fibre to the property supply (with BT). At the time nothing was said about microfilters and none were supplied (other suppliers have given you 1 with the router).
However, whilst the connection is fast (around the 76MB advertised) it frequently drops connection. So if I try and play a game such as Clash of Clans or its cousin Cladh Royale that requires a permanent, stable connection I have to rely on 3G.
A thought I had this evening was whether this could be down to needing BT microfilters? At the moment I still have the Sky (previous ISP) ones attached, so could removing those, or buying BT ones potentially solve this kind of unstable connection?
Thanks for any advice...
