2 LAN Connections

Hi,
A person attempting to setup a home network called me out today unable to get his LAN to work. See if you can help me with this, because I couldn't figure it out:

 There was a cable internet connection via a wireless router located in the central part of the house (for good coverage). This router handed out addresses with a 192.168.0.xx scheme.

A second non-wireless router was located in the home office at one end of the home. Its only purpose was to provide a network connection for a network copier. This router handed out addresses in a 192.168.1.xx scheme.

Both routers used a subnet of 255.255.255.0. There is no ethernet cable run between the two routers.

Two XP Pro computers were on the network. Both computers had one wireless and one wired connection. The wireless connection connected to the wireless router for internet, and the wired connection was run to the home office for printer access. Problem is, if both connections are active at the same time, any services relying on Internet access fail. If the ethernet connection is disabled, the wireless internet works fine, but the computer is not able to print.

I was looking a the network bridge feature in XP, and enabled it, but that did not resolve the issue. I think perhaps if the routers were setup correctly it might, but I don't know. Is there a way to make this situation work with internet and printer access over both connection simultaneously?

Thanks,
Bill

Maybe this seems like the obvious question.. by why does he not just make it one network?
Use either router .. not both.  IF he is only using the router for a printer, just dont use the WAN port, and disable DHCP. Now its a standard switch.
Or go the otherway and make the wireles just a WAP and not a router.
  Am i missing something/

as a side note:
Have you tried making the default gateway for both networks the wireless routers ip?

The problem is the internet is only available where the wireless router is, and the network cabling comes together in another location, the home office. I suggested to have the cable company move the internet router to the home office. Internet is only available at the wireless, printer is only available at the wired router.

I did not try your gateway suggestion, will try that.

I'm assuming that I would collapse everything into 1 router.  Set up the wired router with the internet connection on it's external port and the PCs and wireless router on its internal ports (assuming that there are enough).  Run the wireless router in "bridged mode", which will keep it from NATing internal addresses, and assign it an IP address on the internal subnet 192.168.1.x/24.  
I can't imagine why it was originally set up this way other than there were some logistics issues with the cabling.  If that is still the case, I'd use a wireless bridge on the hardwired router to address it.

OK,
Given that added tidbit I'd use a wireless bridge or a ethernet over power solution to bridge them (assuming that cabling is too cumbersome or expensive)

The reason the internet shuts off when the wired connection is on, is because both routers are giving out separate ip addresses and the computers are getting confused on which one to use. Since there is not physical cable run from the Wireless Router to the Wired Router you cannot make this a working network. The best bet (without running a physical cable) is to buy a wireless network adapter for the printer. Depending on if it is USB or Parallel, you can pick up an adapter at a local computer shop. Best buy even sells these:

You're looking for a wireless print server.
If that is out of the question, then you'll have to explain to the client that they need to move the cable connection from the center of the house into the office and just hook up the wireless router. If they are unsatisfied with the quality of the wireless connection, they can purchase a wireless access point:

Put it at the center of the house, and that AP will connect to the other one and extend the range.
