Internet is super-slow, restart fixes->why?

Hi!

For at least 24 hours now the internet has been incredibly slow on my Alubook. By super-slow I mean 10-15 minutes to load MacRumors. I was sure it was my connection, until I today tried it on my iPhone on the same WiFi network. Took a couple of seconds to load.

So I then thought Safari might be the problem, but I found it was equally slow in Opera and Firefox.

The only thing that worked was a restart of OS X! So much for my uptime

What can this be caused by? Anyone else experienced the same issue? I would like to avoid this happening again, I don't like restarting to fix a problem. One of the reasons I got a mac

Thanks, iPeter! Though I was already running with openDNS.

I find it interesting that a restart fixed it...

 

iPeter: Thanks for your suggestion! I will try changing channels.

IntelliUser: I'm on 10.5.8.

It's never happened before, so if it doesn't happen again I guess I don't need to worry too much...
