How come DSL connection work if modem is plugged into one specific phone jack and not another?

I had problems with my DSL connection before. A technician was sent in and he worked on it. He worked on a phone jack in the basement where my previous room used to be and the internet works fine if the DSL modem is plugged into there. However, if I bring the modem upstairs and plug it into another phone jack, the connection does not work. Any suggestions?How come DSL connection work if modem is plugged into one specific phone jack and not another?
Most DSL installations require a ';splitter'; on the phone line. Often, this is just a little ';dongle'; with a short piece of telephone cord on one end and a telephone jack on the other. The other way is to have a technician connect the splitter at the main cable.





You may need to purchase a splitter and install it on your new phone line. Fortunately, these are fairly cheap and can be purchased for under $10.How come DSL connection work if modem is plugged into one specific phone jack and not another?
Its the wire. You can try taking the jack off an and making sure they are all in tight. I had to run a new one to one of my bedrooms. The phone only has to use limited frequencies and the DSL line requires a much higher amount.
Gigagremlins. They are everywhere and cause inexplicable problems. Honestly, sometimes phone plugs closest to the main entry point seem to be more reliable.
