Very slow "contacting / looking up" websites in firefox & safari - help!

Hi, I have the latest rev 12" ibook that works like a charm. At my apartment, I have cable internet and use a 54G router, and airport works flawlessly, pages load fast, etc.

Whenever I use my ibook at my parent's house (also has cable) it takes several seconds in the "looking up / contacting" stage (in either firefox or safari) whenever I try to go to a new page. These are big pages like cnn, google, nytimes, etc.

It's fine once I'm on a page and browsing (as long as I stay in that domain) but if I let it sit for a while and then try to reload, it has to do it's contact / lookup again.

The connection is super fast on all the wired computers, and on PC wireless laptops.

Does anyone have any idea what could cause this slowdown? Could it be whatever type of encryption is being used?

Thanks - I'm at a loss! :(
 
I know it's fine on the other PC laptops, but have you tried resetting your router? Unplug it and leave it for half a minute, plug it back in again and see if that helps. It's worth a try. :)
 
After various resets in the past I haven't noticed an improvement in the speed, unfortunately.
 
Sounds to me like the DNS records on your Mac are corrupt somehow. Bad DNS = long delay before it figures out those DNS servers don't exist and finds the right ones.

To fix this, check one of the working machines DNS server settings and change yours to match.

Yes that makes sense - I was thinking it had to do with the DNS stuff - but how do I fix that on my mac? I thought everything was automatic? Is there a setting somewhere?

Forgive me, this is my first mac and i'm not very familiar with the network settings.

Go to System Preferences, then Network, pull down the Show menu and choose AirPort, click the TCP/IP tab, look at DNS Servers text box. That's the one.
 
Ok, I checked that textbox and it is blank. Should there be something there?
 
I fixed it!

I entered the primary, secondary, and tertiary DNS servers listed for my ISP in the DNS field and that fixed it. Now everything is fast!

I guess I just thought you could get that information from the router when you use dhcp to get your IP address, but I guess not?
