I know on firmware 126.96.36.1994 I had a problem with my 9700 on WiFi. If I was moving from one AP to another AP (like from home to office) the dns info was cached. Fixed with 188.8.131.521.
A quick check is to reboot the phone. Or goto Connections, WiFi Options, Blackberry button, DNS Lookup, then Blackberry button again and select Clear DNS Cache. Disconnect from WiFi then try again.
