Is this Possible?
The reason i want to do this is because i do not know if i will always have a BT Internet and might move to cable in future so i don't need to get 2 different routers.
If i get a N router with DSL modem, then i move to cable Internet then i have to buy a new router, but if i do it the way i described in the pic above.
So if i did get a cable internet next month then i can just remove the DG834GT and use the WRN2000 with the cable like, until then is it possible to use it the way described.
