The info:

Two buildings - a two-story house and a 3-room shop, approximately 150 ft
apart.
We need internet in the shop.
There is cable modem and a Belkin wireless router in the house (not sure of
model or firmware, but can get it tonight if needed)
The cable modem and Belkin are on the opposite side of the house from the
shop, about 4 rooms and 4-5 walls deep
At this time laptops will not pick up the Belkin's signal in the shop.

I would like to create a wireless bridge. There are two additional wireless
routers available to us, a Buffalo and Linksys WRT54GL, both running DD-WRT
v24 beta, with the Repeater mode option. The Belkin supports "bridging"
mode, where it will allow other APs to connect to it. Not sure if this
includes something like the Buffalo in repeater mode.

I was considering putting the Buffalo near a window facing the shop on the
second floor of the house, as a repeater off the Belkin, then using the
Linksys in the shop, bridged back to the repeater.

With the info I've provided does that sound like a viable option? Secondly,
if so, could someone help with the network settings involved? I'd like to
achieve a "client bridge" arrangement, where the Linksys in the shop is a
wireless client on the same subnet.

I've done this several times with WAP54Gs bridged (not including the Bufalo
repeater wildcard), but not with disparate routers.

Please let me know what other info I need to provide.

thank you,
