Two WRT54G routers to serve one house

[kramca]

Primary WRT54G receives feed from cable modem. Two desktops are hard wired to it. Serves one end of the house with wired and wireless service fine.

The other end of the house has weak wireless service.

I got a second WRT54G. The input of this is fed by a CAT5 wire going under the house from one of the output ports of the Primary WRT54G

Not being savvy in this, I need a step by step configuration instruction.
If I need to first know the firmware of each router, I have the serial numbers but don't know where to first find the firmware....Maybe that is square one.

Any help appreciated

The third answer in this link descibes the setup.

I myself have a tplink router and 2 wrt54gs routers setup at home.
I installed the dd-wrt firmware on both linksys wrt54gs's and set them up as wireless client bridges.
The two wrt54gs connect wirelessly to the main tplink router and then one feeds two laser printers in another room connected via ethernet to the router. The second wrt54gs is setup exactly the same way and sits in the TV room to provide a connection to the xbox so it gets internet access without running 50 feet of ethernet cable through the ceiling.The connection on the xbox also saves me buyingh a wireless adaptor for the xbox canadain an xbox wireless card is $100.00 a wrt54gs bought off ebay was $25.00. I have some lag and was almost blaming the setup but when playing with other buddies on xbox live when i have lag they have lag as well so i assume it is xbox live lagging as usual.

Thanks. I may have actually solved my issue in a different way.

I moved my old WRT54G to the middle of the house....let the line under the house be the feed from the cable modem....and so far my Mac, with airport is online and certainly the laptops will be fine with the centrally located router.

If the PC also picks up the signal, I am good and did not need to buy this second router !

Simple solution:

Second router. Connect to it and disable DHCP. Connect the cable from the "output" (LAN) jack of the main router to one of the LAN jacks of the second router. Everyone thinks you need special firmware to bridge a Linksys - you don't.
