Broadband microfilters

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...

A TalkTalk engineer who came round recently to fix my super-slow B/Band found 1 missing filter and 2 dodgy ones - they can become faulty. He said to always have the filter on every phone line......surprised BT hasn't supplied them as T/T always has

Seem to recall whenever I've had the upgraded BT routers they've always come with them and the books always state that every phone port needs one fitted.

Is there a difference between microfilters - ie do you need BT ones for a BT connection, Sky for Sky, etc or should they be interchangeable?

Thanks

No they are interchangeable
