There are a couple of things I'll throw your way.

Ted and I have been having cable weirdness too.

Our cable supplier is hooking up with Yahoo, and they've been installing spam filters. So, now any e-mail that arrives with any adult content in the subject line gets tagged as [Bulk]. You might want to check with your cable supplier to see if these filters are going wonky, or if it even applies to you.

We have three machines hooked up through a router. Ted accidentally shared the entire c drive of one of them, and ever since then, the second computer has been weird. It has no resources to load anything, it says it doesn't have enough memory, but it does. There's a bunch of crap loading, but we can't figure out what it is.

Today, we couldn't get on the Internet at all. Ted eventually hooked the cable direct to the main computer, the Internet's working fine now.

I don't know if any of this helps.
