I have had a bit of a tidy up with my wiring this afternoon. After I had fusion installed I moved my router/modem etc to the basement and used a patch panel to distribute the adsl/phone service around the house using cat5e.
The area where my router was placed wasn't near the old jackpoint so I had a couple of extension cables set up.
This afternoon I have moved the telecom cable coming into my house and now have it set up to feed my modem directly. I cut the plug off the end of a modem cable so I could conect the two telecom wires directly to my modem. In fact I haven't even put the cables in any connectors or anything at the moment I just twisted them together using my fingers and left them. (I wil tidy them up later).
My adsl speed using speedtest.net used to average about 2400kbps. It is now averaging around 4000kbps. Upload is about the same, 550kbps.
Cutting out all of the other plugs/extension cables etc seems to have increased my adsl speed by about a third!
If you have fusion and have no use for telecom jackpoints etc I would recommend this as a possible option for getting the most out of your connection.
