    Hi people,

    I need some help on a puzzling problem. My ISP TPG has said that my net keeps disconnecting due to a high capacitence in the line. I recently joined them as well and it is adsl2+. They said it means a device is unfiltered, but I already made sure they are all plugged in and have re-plugged them.

    I called them up and they said it could be that my adsl line to the phone socket is too long (15m approx.) they said it affects the inteference or something and it could be causing the disconnections. I was told to get the adsl line to 3metres max but I would have to get a long ethernet cable.

    I then decided to check if their was a problem with the filters. I tried them both on each socket but I still had disconnections. There is hardly a chance both are faulty. However, when i tried the adsl line with no device connected it did not disconnect at all but I do need a phone. However the other phone socket had a disconnection when tested.

    My adsl2+ modem/router is TP Link 8840 and the filters being TP Link as well S102A or something.

    So really my first question is if the length of the adsl cable to the phone socket actually matters, some of my friends say it doesn't but I really don't know whether to waste money on an ethernet cable.

    Another is whether anyone has ideas of what could be wrong?

    Thanks

    PS. I'm sorry it is a super long post

    Well, they seem to have narrowed down the issue to your interior wiring. If you're using flat cable to connect to your modem from the phone jack to your modem, that IS a problem, and can create the very issue you are talking about.

    Here's my fix for interior wiring for DSL/ADSL installations.

    Purchase a DSL splitter and install it at the telco NID (Network Interface Device). This is the place the telephone lines come into your home wiring, usually either in the basement or outside near the other utilitiy connections. Run a direct line from the DSL port on the splitter directly to the DSL modem. Connect all of the other phone instruments to the telephone output of the DSL splitter. All of the DSL analog side wiring should be CAT3 or better twisted pair from the telco service entrance to the DSL/ADSL modem. You can use one of the twisted pairs in CAT5 cable if you have that on hand. The splitter I've used in the past is the Wilcom PS-36, it's good for any DSL/ADSL service worldwide.

    This is as good as it gets for DSL installations, and will usually solve in-house wiring issues.

    Here's a good detailed description of the process: DSL Wiring Upgrade Tutorial

    So if I get a long ethernet cable and have a short adsl phone line it should hopefully fix all my problems?

    The dsl wiring is impossible for me to do and it is not just because I would be very puzzled, but I live in a unit.

    You want a twisted pair phone cable to connect the modem, probably a short one would be best. The Ethernet cable can be as long as required, up to 100 meters.
