I was previously on ADSL with a modem (Motorola Netopia 2210-02) and a router (Rosewill RNX-N150RT). The modem acted as the DHCP server
and was plugged into one of the non-WAN ports of the router along with all the other computers.
The only reason that makes sense, since you mentioned this, is that you can reach the modem and router admin pages but it doesn't make much sense why would you want to read the modem admin page.
I could access the router on 192.168.1.1 (its default page), the computers on 192.168.1.2-6 and the modem on 192.168.1.254. I could access both router and modem admin pages with a web browser at these addresses.
Well, im interested why you don't plug it into the WAN port like a normal human being
Now we changed services and are now with a cable modem. I first tried pluggin the cable modem directly into a PC to check if it was working, I could access its admin page at 192.168.100.1 (it's a Motorola SB5101). After I verified it was connecting to the internet fine, I put the router between the two like I was doing before (both plugged into non-WAN ports) and rebooted the devices. I can access the internet just fine with all PCs now, but I can't access the admin pages anymore! 192.168.1.1 doesn't answer a ping (it says delay exceeded), 192.168.100.1 answers a ping but gives 324 (net::ERR_EMPTY_RESPONSE) when I try to access it through a web browser.
The default gateway for the PCs is still 192.168.1.1.

I suspect one of the routers has the same IP address to access the control panel as the modem.
See if you can change the base address of the router from 192.168.1.1 to 192.168.2.1
I might be off on this...
Or the modem is acting like a network, and the router is acting like a second router and going through the second router, it can't reach the specific IP of the modem.
I think the problem is similar to what I had when I had two routers and devices could not see other device on the opposite router.
I essentially disabled DHCP on the 2nd router and pointed DHCP server control to the 1st one.
This made the 2nd router an extension of existing network vs standalone.
This allows all the devices on either router to see each other.

The issue can't be multiple DHCP servers when I connect the modem directly to a PC, I can access the config page for the first 10 seconds and then after I get the same error 324.
The issue is multiple DHCP servers
It's a new modem and it doesn't seem to have any reset button. I factory resetted the router multiple times now (only way to get the connection back up when it goes down apparently).
when you change services it's always a good idea to reset BOTH devices (modem and router) to resolve any conflicts that both may have....

What does that mean? The default address is 192.168.1.1.
does your router have a domain setup for accessing the config?
I have no idea. It's a motorola SB5101U.
also does your modem have a backup battery?

Yeah, I did exactly that yesterday and it finally worked.
So shutdown everything - since your modem will cache last mac connected to it. Then boot the modem, give it time to get online. Then connect your routers WAN port to the modem, and your pcs to one of the lan ports and you will be good to go.
