With this information, can you figure out how my network is setup?

I live in an apartment w/ 4 bedrooms. Each bedroom has 4 ports. Earlier this year, I setup up a workgroup that all 4 of us joined. Our connection to the net is capped at 256kb/room, but our LAN is 100mbps. I assumed that there must have been a router somewhere in the main office and each building had their own switch. However, a few weeks ago, I purchased a wireless router and when connecting one of it's switch ports to the port in my wall via a crossover cable, I was unable to connect to the router to configure it. I was able to connect to the router if I didn't have it connected to the port at all. I tried turning off DHCP and connecting it again, but was still unable to get to it. Finally as a last ditch effort, I connected the WAN port to the port in my wall via a patch cable after enabling DHCP, and I was able to connect to the router with IE and everything seemed to work fine.

Now I'm trying to add my other roommates who are still connected through the ports in their bedrooms. They can't see me on the workgroup and I can't see them. They also cannot connect to me. Furthermore, when I ping my machine name from their computers, I get this IP: 10.1.0.254, which is the same address that is listed for their default gateway.

So now I'm left wondering if there is a router somewhere in the community and maybe I should NOT be using the WAN port on my router, but if this is the case, why can I not connect to it when I'm using it as a switch only? Does anyone know if it is possible for them to join my workgroup in this current state?
 
If you are connected via the wan port of a router to another network, you will not be able to see those machines, and they will not be able to see you. You are on two different networks now, and NAT is also going to act as a natural "firewall" of sorts, pretevting someone on the other side of your router from seeing your machine.
 
Try setting all the default gateways to the router IP address. Is the ping that you are getting from the other computer to yours the IP of the router? The gateway is how you see a computer on another subnet. You made a subnet when you separated the computers with the router. (If I'm understanding you correctly)
 
When I ping myself from their computer, it brings up the gateway that they connect through (not my router).
 
Here is the post from before when I was trying to use the router only as a switch:

I have a Netgear wireless router MR814 that has been giving me some headaches. This is the structure of the network as far as I can tell. There are about 11 buildings in the apt complex I'm in and each 1 or 2 shares a switch. Every bedroom in each apartment has a port that is ran from the switch. I made a crossover cable and connected it to one of the regular ports on my switch and also plugged my dekstop into the router w/ a patch cable. I booted everything up and was not able to connect to the router 192.168.0.1, but I was able to use the web with my desktop and wireless devices.

I then unplugged the uplink and left my computer as the sole connection to the router and tried again. This time I was able to connect to it via 192.168.0.1. So I changed the following settings:

Network Name
Turned off DHCP server

I thought that turning off DHCP would fix the problem so I plugged the router back into the network and rebooted everything. However, I was still not able to access the router via 192.168.0.1. So I thought I would try to tinker with the settings a little more. I removed the uplink and rebooted everything. However, I lost my ability to connect to the router via 192.168.0.1 when my desktop was the only thing connected to it. I'm assuming something I changed (maybe DHCP?) resulted in me losing this ability.

Also, someone pointed me to a webpage tutorial earlier. I followed all the steps except I didn't know what to do with this one:

- Main Router?s base address is 192.168.1.1, with a DHCP server range of 192.168.1.100 to 192.168.1.150

- Set the Cable/DSL Router to (the one you're using as an Access Point) base address to any IP address between 192.168.1.151 to 192.168.1.250
