Anyone know a thing or two about networking?

[Xer0]

Long story short my NIC appears to be on its way out and rather than spend $20 on another POS that's going to crap out on me I thought I'd give setting up a network access point of sorts up.

The problem I am having however, is that my intention is to pick up Router B's broadcast and allow my computer to connect to it with an ethernet cable connected to Router B.

I only assume that this is possible considering there are a dozen ways to do it wirelessly, but I frankly cannot find a guide for this procedure in particular-- all I can find are wireless access point instructions and even after following those I cannot get an internet connection.

The instructions I followed so far were basically

putting Router B within the same subnet mask, but changing the IP so that is was not within range of the primary router (basically change the last digit of the second router from .1 to .2)

DIsabling DHCP on Router B

edit- seem to have fixed it. router b didn't seem to take too kindly to having it's IP reassigned so I just switched the two and all seems to be well.

Ensuring wireless security options were identicla, and that the SSID was also identical.

Basically every guide I've found so far seems to be dependent on having the two routers hardwired to one another.. anyone know if this is possible without such accommodation?
