<div class="IPBDescription">Help!?</div>My network at home currently goes like this..
Modem goes to Wireless Router and I have two PCs that connect to that router with wireless adapters to get Internet access that way.
What I would like to do is take another router and hook it up between my two PCs with Ethernet cables so that I can share files way faster.
The problem is, when I hook up the second router and the two PCs to that router, everything just completely stops working.
I've tried to Google a solution but I haven't been able to find anyone trying to do this so I've gone by some other tips but to no avail.
Any help would be appreciated. =)

what kind of routers are they
why can't you just build a rollover or whatever cable is for pc2pc connections and just do that?
Check the configuration of the second router, make sure it does nothing routerish, DHCP, firewall, routing tables etc.
@ TAK: I don't have the two routers connected to each other, I want them to work separately. Which now will be just the switch all on its own between the two computers with two straight through cables going to each.
Is there something special I have to do to get the switch to work?

Let me show you my excellent mspaint skills:

Step 1: try to ping a PC
Step 2: wrap your head around Windows file sharing
Step 3: curse at Windows file sharing and set up a FTP server (filezilla?)
I do this myself between my old and new computers, because I only have one cable running to this room from the router. The router (and the rest of the LAN) are on 192.168.2.X as well as the motherboard NIC in my new machine. The secondary NIC and the old computer are set to 192.168.3.X and are directly linked with a cable. Windows sees what's up and knows what to do and sharing is all fine and dandy. (between the two, that is. other machines on the LAN can't see my old one, but they don't need to, and I assume that's the case for you too.)
-By default, wired connections (normally) take priority over wireless, when detected as connected.
-Unless you set up IP addresses manually for the wired connections, they're trying to request a DHCP lease. If you're using a switch, there will be no DHCP server available on the wired interface, and will not be able to connect.
-If you're using a 'home router' (which aren't actually ROUTERS, but usually just embedded NAT devices), it will provide a DHCP return setting your default gateway to itself, in a default configuration. As it has no WAN connection, packets just die there.
What you need to do:
-Use a switch or crossover cable to connect the systems. MANUALLY set up IP addresses on the wired interfaces on a different non-routable addressing scheme from the ones your wireless router provides. (ie: If your wireless IP is a 192.168.x.x, use 10.x.x.x for the wired, and vice-versa. Usually 10.0.0.1 and 10.0.0.2, or 192.168.1.1 and 192.168.1.2 with a netmask of 255.255.255.0 for either of them)
-REMOVE the default gateway entry/ies from the IP range on the wired connection.
-Set the wired interface to take higher priority on your adapter list (with the gateway entry removed, it should only route traffic for THAT network schema over the interface)
-<b>RUN WIRES.</b> Seriously, stop being a lazy-***. It's faster, and wifi was never meant to replace an ACTUAL network, just to provide connectivity to mobile devices. The fact that it's easier means people will pull half-***ed crap like this, making more headaches for themselves and anyone in the vicinity of their RF bubble. This isn't 'strange'. It's something to be slapped for doing. ****.

I'll hook up the switch when I get home, and use 10.x.x.x since that's probably what messed me up in the first place..
My wireless router is 192.168.10.1 so I was setting the switch manually to be 192.168.20.1

Sadly, the prevalence of wireless means that people are increasingly willing to smugly slap down any request for some goddamn cable to be laid in, because yeah we're totally going to be satisfied with an inferior, ###### solution just because the stuff that works reliably would require a smidgen of effort of them. And then they go "well everyone else is connected, you must have screwed up your settings" when their ###### doesn't work. I feel your pain Anarki.
Oh wait, now I went and ranted anyway.
You see you can get these rather cool things that plug into your wall sockets and run a wired signal through your electricity wires. They're basically a box you plug into your wall and it has an ethernet port on it. You plug one end into the router, one end into your PC, and you magically get an ethernet connection between two electrical sockets.
You could use that for your two PCs, they are however quite expensive, I think mine was £100 plus.
It's handy for me given that my PC is in the back bedroom while the man from virgin decided the best place to put the router connection was behind the sofa in the living room, as my mum isn't the best computer expert she didn't think to tell him to put it somewhere intelligent.
That is ALWAYS an option. If it truly isn't (which means three feet of concrete and NO conduits, anything else is just lazy-*** excuses), look into a DEDICATED wireless ethernet bridge.

If your netmask is 255.255.255.0, then changing the third triplet should work just as well; you just need to create a new higher-priority route ONLY for that subnet

Yes, those are 'powerline' adapters. As noted, hate those quite a bit; induce RF interference on the power lines of your home. Anything without a filter setup is then subjected to the additional line noise in what SHOULD be a nice, smooth sine wave. Can cause erratic behaviours in all KINDS of electronics; some more sensitive gear can outright FAIL if one of those pieces of <b>****</b> is installed.
