In my house of 6 roommates (3 upstairs, 3 downstairs) we have an outbound connection to DSL Internet. Our network is fairly simple for a dual router configuration. Our main router (call it wired) has the following properties:

* Connects to Internet
* Internal address of 192.168.1.1
* 3 Computers, 1 Router connected to it

Our secondary router (call it wireless) has these properties:

* Connects to Wired
* Internal address of 192.168.3.1
* 2 Computers, 2 Wireless Computers, 1 Xbox connected to it





My minds a bit rusty on how we connected the 2 routers, I believe we used normal CAT5 cable, not a crossover. I'm also trying to visualize whether Wired had a special port for hooking up a router to it. I don't believe it does, I think the connection sent to Wireless is coming out of a regular "Port 1" connection, into Wireless's WAN port.

Anyways, Wireless can see Wired - the router admin page, the router, all its computers, etc... this is obvious because thats the logical path to the Internet. The problem is that Wired - and all the computers on it, cannot see "down the chain" so to speak... they cant see any computers hooked up to Wireless. I'm wondering what the easiest way to change this is (preferably a software solution). I'm pretty sure a simple crossover cable would do it, but I don't really want to buy more cable (its about 50+ feet worth to run it upstairs).

Thanks.

The reason wired cannot see wireless is because the router has a firewall built-in, it is not letting itself be known to the network, they will be dropping any packets of data that are thrown at them from wired side, this is the purpose of a firewall, even though it is a sub-network of the main network.

If you want all computers to see each other, the only thing you could do is change wireless from a router to a switch, and then have them all on the same network ID, unless the router has a bridging feature then you can put it into bridging mode and let them receive IP addresses from wired.

Yes CAT5 cable is all you need, routers will do the crossover for you so you don't need to worry about the crossover cable. Only need crossover cable for network cards, they are unable to crossover the data, so you need to install the crossover cable.
