Hi Peter
I had a very similar problem at home too.
It has to do with Safari 5.0.1 & later "prefetching" DNS lookups and your router or your ISP's DNS server not handling the number of requests

Two options
- use another DNS server e.g. 8.8.8.8 & 8.8.4.4 (google's open servers) instead of your ISP's.
 - use Terminal to disable Safari's prefetching...

defaults write com.apple.safari WebKitDNSPrefetchingEnabled -boolean false

Apple Support article... <http://support.apple.com/kb/TS3408>

Changing the defaults seemed to work for me.

cheers

Hi all, last night was the last straw to motivate me to write this. The Macbook (Snow Leopard) is connected wirelessly in the house, my wife was using Safari to check news.com.au site last night and it just froze, as it has done many times before over the almost 1 year we’ve had it. My old reliable Windows laptop alongside (2 metres away) I used as a control experiment and was instantly able to get the news.com.au site up on screen. She Quit Safari and started Safari again with no success. Wireless signal was showing “Excellent” on the Windows machine alongside and minutes before, the Macbook was able to web browse without issue. Ultimately a restart of the Macbook got it going again, but what really was the problem?



Any tips on when it recurs how I might diagnose the root cause?



I’d like to download Firefox as a way of removing Safari from the ‘risk register’, but that strategy is a bit archaic to say the least.



Thanks.



Peter.
