hi there so i ran a 30metre ethernet cable from my sky router to an xbox 360, then realised that it wont reach where i need it, so i moved the router hoping to plug the ethernet into the adsl slot but the cable is slightly too large i think the hole on router is rj11 the wire is rj12 i think, bassically i need to use this wire, on one end its to big 4 the router and the other end is too big to go into the filter box thing that also has my fone socket, could i use 2 adapters one on each end and will it work, please help me!! thanks
