linking BT Voyager 220v to a non BT wireless router

[FLUTTERBY]

I have read that to get BT Broadband Talk with a non BT wireless router you should buy a BT Voyager 10V adapter.

We already have a BT Voyager 220V. Can this be used instead of the BT 10V adapter?

Alternativelty is it possible to have the 200V and the non Bt wireless router working independently? We only have one BT land line coming into the house.

The minimum equipment we want to link into the routers is:

• PC running Windows Vista, Xbox 360 and Ninetendo Wii which are in the same room as each other
• PC running Windows XP in another room which is where the Bt telephone socket is.

My son and I have spent hours trying different combinations of wires. Perhaps a change in configuration would do the trick?

Hope someone can help.
