Setup a network behind another network

Hello,

I would like to ask for some help understanding how best to set up a network.

I have just moved into rented accommodation. The landlords live next door and have a wireless router (DLink DIR-635, Firmware: 2.23EU, Hardware: B1) which reaches nicely into our new home. They have said we may use this as our Internet connection.

I have a Belkin N1 F5D8231-4 Ver. 5000yy wireless router driving my own LAN.

I'd like to have my Belkin pick up the signal from the landlord's DLink and use that as its WAN. I thought it would surely be possible, but I can't find anything that looks like it would work in my Belkin's admin panel.

It's important that I keep my network separate from the landlord's. I just want to route my Internet (WAN) traffic via his router, that's all. I'm sure this should be possible, but is it? Do I perhaps need some extra hardware? (A wireless bridge, is it called?)

Many thanks for any help you may be able to provide.
