I got connection on LAN, but no internet

[Gackt]

Recently I tried playing a game on the DS with the wifi and I couldn't figure out the WEP code so I tried getting into my Netgear WGR614v6 router, but forgot the password for that as well.

So, from the suggestions I read on Google, I did a full reset to factory settings, and I was able to set everything how I wanted, still had DHCP on and all the automatic ip addresses and other shit. But when I tried to get on the internet from my other pc that uses a wireless adapter, I could not surf the internet, I had no internet connection whatsoever. What baffled me was that I had a strong signal from the router, so I tried to repair connection with windows and it told me that I couldn't renew the IP add. I had made sure the WEP code was right and all and tried it without. Tried pinging google too but was told that it couldn't find the server. This is my first problem.

The second problem began today, when the computer that is near the router and uses wired internet, could not surf the internet either. It worked before I went to bed. So I tried resetting and installing new drivers, no change. What pissed me off was that it was sending and receiving packages. But fucking Firefox would just give me the 'server not found' message. The internet works fine without the router, but the router is essential. I had a DNS assigned, and all other IP, subnet mask. I am just so angry that I have a local area connection, but the router is mysteriously fucking it up. Any help would be severely grateful.

In CMD I type ipconfig and there was nothing in the DNS Suffix space, would that have something to do with it?
