I have just gotten connected to the local fiber optic Internet line! Fast, fast, fast!
But there’s a problem: I can’t connect to a number of sites. Specifically, I can’t access:
And most of Yahoo’s services. In particular, I can’t access the server that hosts Yahoo’s login system. Which means that I can’t manage my Fantasy Baseball teams, I can’t manage or post to my Yahoo! Groups, I can’t read my Yahoo Mail accounts, etc.
I also seem unable to connect to some server(s) that serves streaming content; some sites load, but when I click on video links, the video won’t load.
Here’s my connection’s hardware setup:
Fiber optic line into the house
Line goes into a D-Link ethernet router, which also serves as a DHCP server
Two lines out of the router - one to my roommate’s PC, the other to my Mac
I first thought the problem with accessing these sites was with my Mac, but it turns out I can’t reach those sites from my roommate’s computer either. So the problem is upstream somewhere.
Somebody suggested to me that this sounds like a DNS cache problem. I assume that the DNS cache would reside on my ISP’s DNS server. However…
When the tech was here hooking us up, he had me trying to configure my PPPoE, saying that was the protocol to use. It didn’t work, though, and he unfortunately couldn’t stay any later to figure it out. I told him that my stepfather and mom have the same fiber optic setup, and Macintosh computers just like me, and that I could call my stepdad for help.
From my stepdad, I found out that I should use my DHCP settings, just like I had done with the DSL connection I had at my previous residence. Sure enough, using DHCP got me up and running.
So is it possible that the DNS cache is stored in the router? That doesn’t seem likely to me, but it would make a certain kind of sense if my early, unsuccessful attempts to reach those sites got logged in the cache as being nonexistent. So now when I attempt to reach those sites, my connection is going to that cache instead of to the proper server…
I can still access these sites if I use the dialup AOL account I was using temporarily while waiting to get the fiber optic connection. I can also reach the sites if I go through a proxy, such as anonymizer.com. So it’s clearly a problem with my connection through my ISP.
I have already sent an e-mail to my ISP’s support address, but I have yet to hear back from them. In the meantime, does anybody have any suggestions for things I might be able to do from here to fix this? It’s absolutely vital that I be able to access www.apple.com , because I need to download software updates.
