I've been looking at bridges and game adapters, like the WET54G. What torques me to no end is that my router with 4 port switch (WRT54GS) is cheaper than these devices....
Going to have to look on e-Bay or something. Spending more on a device dedicated to a single piece of hardware doesn't make a whole lot of sense to me..
If you are willing to do a little work, you may be able to get around that. At this link there is a FW that can be put onto a Linksys router like yours and this firmware has the capability of setting the router up as a client bridge. It might be an answer for you as a cost savings. I have not tried it but I too was looking at a more suitable way of doing this and this looks like it will make all four ports on the Linksys router a bridge device with port forwarding over the wireless portion.
