I had this problem and unfortunately my router has no support for IPv6 and no newer firmware. Thus I had to bypass my router for DNS queries. Once I did this all my slow internet with OS X Leopard problems were solved. To state it simply you bypass the router’s DNS by specifying a DNS server other than your DHCP router in network preferences > (interface) > advanced > DNS.

Detailed instructions are available here: http://installingcats.com/2008/06/05/slow-internet-with-leopard/#direct_dns_better_dns

Actually I would recommend reading that entire webpage. It helped me fully understand the problem and the multiple possible solutions.

Anybody notice that 10.5.3 no longer has this problem? I have been unable to find any info in the release notes or developer notes, but it appears that they reverted back to making DNS-A requests by default.

I’m having a similar problem – Leopard is generating invalid SRV queries, and grinding to a halt. Your article helped me discover that it was a DNS issue.

Yeah it appears that if you have flaky internet, leopard will cache your ‘failed’ dns entries, which means that unless you are constantly flushing your dns, your internet will be only half functional. Switching to opendns seems to help.

Thanks for this post… I eventually figured out that by configuring my Macs at home to use opendns.com’s DNS servers, my problems has gone away. Actually, my router was configured to use it (netgear router MR814v2 with latest firmware 5.3_05 ) and at first it seemed to not be sufficient but it seems fine now. I’m on Mac OS X 10.5.1
