2 quick simple questions (I hope!) :
1) I have a (post 2007) NTE master OR socket downstairs and an extension upstairs wired into the front faceplate of the NTE. If I plug my router (ADSL) into the extension, providing my internal wiring is of a good standard (within last 12 months so should be v.v.v. good!) will it work and will I have any significant (>20%) drop in connection speed?
2) If I upgrade to FTTC and end up with a modem + router, can this also be plugged into the extension or will it have to be at the master socket?
