I can ping but not browse -- not a DNS problem

This only happens after I restart my MBP. The problem reliably lasts for several hours, then it clears up.

I can ping anything (using either the URL or the IP address).

However, if I browse or telnet the connection only works 1 out of every 20 or so attempts. When browsing for instance I can click reload reload reload reload .... until ... eventually a page might load (with or without pictures or css).

This started after I upgraded to Snow Leopard.

Can anyone give advice or help me isolate the problem?

Try opening your Application Firewall temporarily and see if that allows access.

My Application Firewall was turned off. (I have Little Snitch installed). I turned Little Snitch off and AF on, but it didn't have an affect.

Would this be the kind of thing covered by warranty?

hi humberaquino

so yours starts to work properly after several hours like mine, or never works?

Actually, I did all tests in about an hour. After that I turned off my Mac.
I´ll leave it on all day tomorrow and let you know if it behaves the same way.

Best regards

hi islandgrldotnet

Is the problem also intermittent on yours? My browser connects about 1 in 10 reloads (while pings are 100%0.

Cheers, Adam
