Intermittent issues (help please)

Hi - please forgive me newbie status if I am posting in the wrong place.
I have recently moved house (3 doors down) and taken my talktalk broadband with me. Since moving, the quality of my connection is patchy at best. So far i've had a new router (apparently more tolerant to dodgy lines) from TalkTalk, Openreach out who've replaced my master socket. It still drops my data. Any help? Thanks

Christmas lights on whilst testing (including neighbours) ? These can problems.

How are things setup?

Is everything in the master socket?

Hi. Thanks for your reply. Everything is in the master socket with it�s own power supply. I�ve also checked the purity of the mains power for noise and can�t find any.
Have got on order a twisted pair rj11 cable and will be checking for sources of RF noise in the next couple of days. The thing that�s currently annoying me (apart from the dropouts) is 5at TalkTalk seem fixated on it being a wireless problem when my wired connection also drops data.....

Ok, master - filter - telephone and router. Note the master before everything, I've seen some people connect splitters before the filter.

Nothing connected before the filter?

Nothing connected to an extension socket e.g. sky tv, fax machine etc?

Any extensions in use like this?
