(Sorry if this is in the wrong zone. You could fit what I know about networking and routers on a q-tip).
I think what I'm trying to do is called wireless bridging(?). I've got 2 old linksys routers, a WRT54G and WRT120N and want to know if it's possible to connect the two. In other words, have RouterB tap into RouterA's network/connection to the internet. Is this possible and if so, would I need any additional software/firmware/etc.. to make it work? (Yes, I do know there are simpler ways. But that's not my question right now :-)
Any advice would be greatly appreciated. Just please keep it simple for the network-novice.
