Modem/Router Issues

[haffey]

So there I was, just surfin da webz when the internet craps out.

I powercycle both the router and modem, and still no dice. If I connect a computer directly to the modem, it can connect to the internet and all's good (after power-cycling the modem). But if I run that wire into the router, and a wire from there to my computer, I can't. I'm almost convinced the router's fine. It's a WRT-54G, flashed with DD-WRT, that's been solid for at least 2 years. I can connect to the rest of my network as well using it - just not the internet.

I swapped out the WRT-54G with a working DI-524 (at least, I think it's working). It had the same issues as the WRT-54G.

I'm convinced it's the modem, and that there's something wrong with it, because the Optimum Online guy said that I would have to powercycle the modem to recognize either a router or computer. Ok, sounds fine to me...but it only wants to recognize a computer. It's not recognizing a router at all.

What the FUCK is going on here?

the modem is a motorola SBV5120 @ 192.168.100.1 - should i reset it?

1. Power cycle modem
2. Power cycle router
3. Start>Run>"cmd">ipconfig - What IP address do you have?
4. ping 192.168.100.1 - Results?
5. ping 4.2.2.2 - Results?
6. ping www.cisco.com - Results?

fixed it. it may sound stupid, but all i had to do was hold the physical reset button on the router itself.

and here i had the illusion powercycling + web interface resetting was good enough...Thank you for the help though sir.
