Ok the first one is not the working connection, no default gateway and the IP is just default when there isn't one assigned, and the second connection is working.

Does this modem have more than one LAN port?

With most modems using more than one machine you need a router or you need to use ICS "internet connection sharing".

Most modems only have a single LAN port, maybe yours is different or maybe it's one wireless connection and one wired?

My modem has 4 LAN ports. I've had 3 computers connected to the modem before when it was working and all went perfectly. But today it just didnt work anymore on my computer.

So it's a combo modem-router all in one, ok that helps.

Seems like a more complete reset of the modem is required because DHCP isn't working from what I can see. If it use to work and now isn't working that would normally fix it unless something went wrong with this modem-router.

The other possiblity is that the one machine with a problem is showing .0.0.0.0 for default gateway which is a common problem.

You can try manually typing in the default gateway into the Ipv4 properties window if need be.

This link relates to that particular problem and shows how to fix it.

I tried the guides on there and got away the unidentified network to "Network 6" Home network. but still no connection at all.

Network 6 ok, that usually means that there are lots of extra entries in device manager for this connection. This happens after messing with the network but not delating extra adaptors or drivers.

You might try going into device manager then choose the "View" setting at the top then choose "Show hidden Devices" at that point you should see a bunch of extra networks on the list under Network Adaptors. You might try delating or uninstalling them all and rebooting which should allow Windows to reinstall just the ones you need. I can't see any of this from here so I have to guess at this a bit.
