Help: Strange Airport behaviour

[pope24]

I am having a problem with my mac and I was wondering if you guys could help.

When I am connected via Airport there are some sites that just won't load. Noticable examples are www.co.za and www.thetimes.co.za.

If I am connected via Ethernet it all works fine.

Any ideas why this might be the case and how to fix it, because it is really annoying.

Thanks

Check that the DNS settings in "advanced" network settings for each type of network adaptor in System Preferences are identical.
