Set Sky broadband up yesterday, using lan cable to macbook ok. Set up wireless, seemed fine can access bbc.co.uk, and others, but some websites seem to be blocked, ie this one, cnn, disney. All ok when airport switched off and connecting via lan cable. Logged inti router, status ok. Running ping to router interface, via wireless, no delays seen when accessing problem sites. Tried loading firefox browser instead of safari, same problem. Any ideas ?

Check you haven't got any DNS servers set up under Network preferences. If you have remove those or try the OpenDNS servers. Are you using 10.5.x?

Yes I am running 10.5. There were DNS IP's on the mac's network preferences. Unfortunately I'm away for the weekend, but I connected up to another wireless network, using a Belkin wireless G+ MIMO router, with no problems at all.
This setup also needed DNS entries on the mac to get the browser to work. Without DNS entries, could ping web IP's, but browser found no sites. This is weird because the Belkin also has DNS IP's in its config.
