Okay...Well, I just got off the phone with Paetec, the ISP...
In the end (not really), I came up with a few new answers and of course, a few new questions.
1. There is a problem with my router in that it's not sorting out the ISP's IP and so forth...
2. The IP I was getting was wrong and not what I should have been given.
3. He told me the DNS server to use, but said it wasn't really neccesary.
4. He said something about enabling "NAT" on my router.
5. We determined that plugging directly into the wall, I get the right IP and can access the internet. I had tried this several times before but it didn't work....why? See 6.
6. We determined that one of my many cables could indeed be faulty and it just so happened that I used it to connect to.
So I tried working with that info after I hung up the phone and got a few things done but am still puzzled by some...I have 3 ethernet cables. One, which supposedly screwed things up in the first place. One that is too short, and one that is a few inches shorter than that. So it won't reach my desk, but from my router it would. But I can't connect through my router, at least not successfuly and in a way I know how. So I am sitting on my bed, typing this, plugged right into the wall next to me, wondering where in NYC I need to go to get a new ethernet cable.
One thing is bothering me though...The internet is slllooowww. Maybe it's because I AM on a network of tons of people, but it is usually faster during all times of the day. Another thing, upon murdering and resurrecting Safari dozens of times I lost all my bookmarks... iSync with .Mac, right? I thought so too, but can't seem to access it. I keep getting an error. I appreciate all your help in guiding me through this, and unfortunately, I am still accepting suggestions, etc....Thanks!
