Turn off the computer with a connection. Reset Your modem. Then only turn on the computer that's NOT connecting. Does it connect?

This will help determine if your modem really doesn't have DHCP.
If the computer does connect then it means your ISP "has" changed recently and doesn't give out multiple IPs.

EDIT: if your ISP has changed and only gives one IP you should be able to connect with the PC that has connection issues. Maybe your PC is introverted and dislikes connections to the outside world ;P

Hopefully this will completely eliminate the problem. Feels like i'm on rehab, not having been able to game for nearly 6 weeks

Thanks alot so far everyone,
Been a great help to me and I learned a few new things now to!
Don't buy from a local PC shop. If you're in the US, just pick one up off newegg.

I've personally used:
Asus RT-N10+ ($24.99 - $10 MIR)
Asus RT-N16 ($86.99 - $10 MIR)

The RT-N16 is definitely a far superior router if you need it. Gigabit switch, great physical hardware, NAS via USB, FTP Server, torrent box.....I mean its a GREAT router.

The RT-N10+ is considerably more basic, but its still an absolutely solid router, and worked very VERY well for its price.

If you just need something cheap, that works, and even has wireless, grab the Asus RT-N10+ while they've got that $10 MIR offer (even without its only $25).

Please do. It's great to check everything before you go buy something you might not need (Although I do agree with everyone who says you'll probably need to go buy a router).

Nice to see spoony trying to help but it's odd not to see beers, two_cables, or duckie_ho in here posting... WeIrD.

DHCP Discovery are done by broadcast in both directions. The PC broadcasts (to IP address 255.255.255.255) a request for any DHCP server to reply, with a random number in the request. In a cable network, this broadcast is picked up by the UBR at the cable ISP's head-end. The UBR is not itself a DHCP server, but acts as a DHCP Agent. The DHCP Agent passes the PC's request to the real DHCP server elsewhere in the ISP's network. The DHCP server constructs a reply packet, including the same random number as in the request, and sends it back to the DHCP Agent in the UBR. The UBR then broadcasts the reply into the local cable network downstream so that every connected PC receives it!.

So, I had little time yesterday but I managed to try my rig directly on the modem.
Even then it was unable to make a connection, I even restarted the modem to make sure.

I guess the problem might be located somewhere else then?

I go try a full reinstall later tonight and see what happens then.

Make sure that IP v4 is set to auto. Find your network adapter, right click, properties, double click IPv4, make sure its all set to auto.

Next, make sure that the rig in question is hooked up. Then power cycle the modem (unhook for 30 seconds to 1 minute). My modem breaks connection if I switch between my rig and my router. I have to plug the device into the modem first, and THEN turn on the modem.

You should not boot up your PC until after the cable modem has finished its start-up sequence.
With modem connections, most firewalls do not work correctly using their default configuration. Configure the following combinations of hosts and protocols to be trusted with access to the appropriate client applications or processes on your PC or LAN.

the modem itself (usually 192.168.100.1) for any protocol;
your local UBR's private IP address, for broadcast DHCP (UDP local destination port 68);
your ISP's DHCP server(s) for your area, for DHCP (UDP local destination port 68) and ICMP;
your ISP's DNS servers, for UDP from remote source port 53 to any local destination port.

Urgh, I had time to install windows 7 again. To bad it fixed nothing...
I'm starting to get verry irritated now. I'm thinking of just buying a PCI ethernet adapter and see what happens, its only 10 bucks anyway.

I did so, I even unplugged my modem for half an hour and nothing changed.
