I know there's a couple of networking guys on here. Just upgraded my internet service from old school dsl to att uverse to get a little better speed. My question is can I convert the 40 year old phone wire into the house to cat5? The input on the 2wire modem/router is typical rj11. I've already wall fished and wired up every room in the house with 2 cat 5 jacks apiece into modular wall plates so the tools/materials aren't an issue. I guess my question is can I run 4 pair into an rj11 connector and still get service?
