2 routers on the same line?

Question

I have 2 pcs, 1 upstairs and 1 down. I don't want to use wireless internet! Can I use 2 routers, one for each pc without them cutting each other off?

Answer 1

the most convenient way to connect both the PC's will be wireless only but if you don't want to use wireless, I suggest you to invest in a small 4 port switch and use single router and connect it.

If you can tell me the exact scenario, like what you mean by two router, whether you are planning to take two Internet connection or something else.

Answer 2

You can set up multiple routers on the same network, certainly.  Depending on how you do this it can cause some limitations for you.  The machines connected to each router will have different subnets, for instance.  Here at home I have one wired router and one wireless router nested.

If your concern is radio frequency, there will probably be more powerful sources of interference than your routers against one another.

Given what you have described, my first reaction is to merely get one wireless router and connect wireless to that one router from both machines.  Many wireless routers will have some physical ports on them so you could connect one or both machines via wire should you choose to do so (also).

With two machines I can't imagine why you would need more than one router.

---------------------------------

Your provider was probably saying that you could not connect two routers directly to the modem.  You should be able to nest the routers (attach the output of one to the input of the other) as long as you set the gateway address and subnet range accordingly.  Nonetheless, I agree that connecting them by cable is probably your best bet--wireless is always less secure.

Answer 3

You can daisy chain them with a cable from the first device connector to the second internet or WAN connector.  I wouls suggest you go into the second one and change the output OP address to something from standard.  Since you will be coming in with a 192.168.1.X and doing a NAT to the output of 192.168.1.X,  it may get confused.  Set the output to 192.168.20.X.  Less likely to get confused that way in translation.
