DSL Filter or not
I have just recently been having problems with the speed that certain websites come onto the screen. Having had a word with my Broadband supplier(Talk Talk), I was given a 24 hour "line test".I was asked before the test was set up -which phone socket was I using as the test had to be carried out using the nearest point to the incoming wire from the road.As I had been using a socket in my hallway(which had required metres of cable before it reached my Modem),I bought a small length to go from the "first socket" to my modem and the test was started. There was a vast improvement with this set up; and then I realised that I hadn't put a line filter in the wiring.I told the support chap at Talk Talk about this but he wasn't sure whether the improvement was due to using the nearest socket to the road or not having a line filter! I then went on to a web site called Hubris which stated (and I quote) DO NOT PLACE A DSL FILTER ON THE PHONE CORD THAT CONNECTS FROM THE WALL OUTLET TO THE BACK OF YOUR DSL MODEM. If you do put a filter on this line, your DSL will not work because the filter strips out the DSL signal your modem needs to connect to the internet!!!
Can anyone chip in with their views??

I think you've misunderstood.
You modem/router needs to be run from the DSL socket on a filter, so if you use an extension lead you plug the lead direct into the phone socket and then the filter into the end of the extension and then your modem/router into the DSL socket on the filter.
What they are talking about (and the mistake a lot of people make) is to plug the filter straight into the main phone socket, then run the extension lead from the phone socket on the filter and then plug the modem/router into the end of the extension, this will not work as you are connecting the modem/router to the side of the filter that has filtered out the DSL signal.
DSL will work without a filter at all, but iif your phone rings, or anyone tried to use the phone it will cut your DSL off.

Chuck is correct about the misunderstanding.
However, as you found, it is best to connect the DSL modem directly to the line rather than through the modem port on a filter. The phone ringing or making a call has no effect on the DSL. I have run my system this way for many years after being advised by our provider.
However the phone must be connected to the line the phone port on a filter otherwise the telephone will shunt the high frequency DSL signal.
