Solved Connecting a printer to two different modem

Specs: Windows 7
Hi,

Currently I have 2 different modem running in my working area which is modem A and modem B. Whenever user from Modem A(192.168.0.1) or Modem B(192.168.0.10) would like to print or scan something using the shared printer, I need to manually plug the cable into either Modem A or Modem B depends on the network the user are currently using.

How I do previously is only set DHCP on Modem A and disable DHCP for modem B so that Modem B will share DHCP assigned by Modem A. Both modems connect to the same Switch with the printer cable so both network user can use it together.

But the problem now is I have to enable DHCP for both modems and causing the previously method can't be use anymore. So is there any other way that I can link both Modem A and Modem B with each assign different DHCP to link with 1 printer?

Please verify, or correct any of what I'm about to say.

From the sounds of it, you have two separate internet connections hooked up each to their own SOHO Router.

You have a network printer you wish shared between the two separate networks and presently have to move the plug from one router to another in order to allow clients on said router to print to the printer.

✔ Best Answer
What you could do, is to connect the two routers physically with a crossover cable from LAN port to LAN port. Both routers have IP's within the same subnet so this will work.

However, if you're going to do so the best way to go about it is to disable DHCP on one of the routers. Two DHCP servers in the same segment is overkill and apt to cause problems.

Since you have to separate internet connections I'm going to assume you need certain clients using one, and the rest the other. If it were me, I'd pick the router with the least number of clients connected to it and give them all static IP addresses pointing at that router as the gateway. The rest, set to DHCP and they will automatically go to the other

Example:

Modem A (DHCP clients)
LAN IP: 192.168.0.1
Subnet Mask: 255.255.255.0
DHCP Enabled = Yes
DHCP Scope = 192.168.0.100 to 192.168.0.199
DHCP Gateway IP (as given to clients) = 192.168.0.1


Modem B (Static clients)
LAN IP: 192.168.0.10
SM: 255.255.255.0

All clients connecting to this device are to be given static IP addresses. Since your DHCP Scope is 192.168.0.100 to .199 you will want to use IP's outside that scope so as to avoid duplicate IP issues. I would recommend using IP's in the 192.168.0.50 to 192.168.0.99 range leaving 192.168.0.1 through 192.168.0.49 for any network devices like routers, printers etc. Ensure when configuring TCP/IP settings on all Router B clients you give them router B's LAN IP (192.168.0.10) as their Default Gateway address. This way all their internet traffic will pass through that connection.

Setup this way, no matter where you plug that printer in, all clients will still be able to print to it and you won't have to move the printer's network connection around ever again.

Alternatively, you could get a dual WAN router, connect both internet connections to it's WAN ports and all clients to it's LAN ports.

My pleasure. For a little more in-depth information I have created a tuturial for connecting a second router to a network. It will apply here and is likely worth your while to read. To see it, click on my name above in this response and read my “how-to” guide titled, “Add a second Router to your LAN

You're going to want to use the single subnet scenario where you interconnect th switches LAN port to LAN port
