@TS: netgear dg834g is a modem /wireless router .y do you still need the belkin wireless router? dont make your network complicated. netgear is already a wireless router. what do you realy want to achieve?

anyway, belkin is only a router not a modem/router thats why it doesnt have telephone port or rj11. let me guess,i think ,you want to extend your wireless signal. better you buy wireless repeater or extender / or wireless AP.

note: check that your ip address will not conflict on both routers. you must use different subnet.

if you can make a diagram of your network connection.post it here so that we can help you better.
