The socket pictured looks like a fairly modern one, so one suspects changing it would not make any great difference - indeed any "difference" could potentially be worse, ie it's a bit of a gamble and no guarantee of improvement.
In any case, everything up to and including the master socket "belongs" to OpenReach and subscribers are not at liberty to tamper with it. You are supposed to get OpenReach to do it and of course they will charge. Indeed, if contemplating paying OpenReach to "do something," you may as well have them move the master socket to a more convenient location.
5m shouldn't be big deal - think about how far it's already traveled to get as far as the MS - a few meters more shouldn't have that dramatic an effect. However, to facilitate such an extension one should use good quality UTP cable (same as is used for ethernet) not cheap flat "ribbon" cable such as is often sold as "telephone extension" cable (same as is often supplied with the router, albeit at shorter lengths.) The "twists" in UTP (the "T" in UTP) reject a great deal of interference, flat/ribbon cable lacks the twist and thus is more susceptible to interference. I've sent ADSL over 100m from a master socket over UTP with no discernible loss of data rates.
There are guides on the Internet of how to attach RJ11 and/or "BT" type connectors onto UTP if you want to make up your own cables or cannot find any pre-made ones. For the cost of a 5m cable at only a few pounds, you might care to "just try it" and see what difference it makes. |
