Ok, ive been in contact with my ISP...We tried everything, connecting with all three routers, and with the modem, isolating the line, so there would be no conflicts, Even removing the front panel of our phone line wall socket to use the hidden mysterious phone line connection type thing.
Nothing. Squat. He was completly dumfounded.
Basicaly, when you put a DSL cable into a router, it automaticaly tries to syncrinaise with the remote server, which then (on pretty much all routers) Switches on the ADSL light, accepting the fact that there is a connection, and you are ready to connect with the internet.
when i connect my modem, he could see that the Sync was attempted, accepted, then the internet connection "hand shake" occured when i was asked to conect...letting me on the internet. But, with all three routers, not a single sync was attempted, nothing was coming out of my phone line and attempting to connect to the server.
It's simply come down to trying a new ADSL line splitter...which even he said is simply absurd, since it allready accepts this connection type with the modem, but we should try everything.
People...What the hell is going on?
