In Leopard it appears you have to click on the Advanced button first to get to the TCP/IP tab, as illustrated on this University of North Carolina help page.
I also noticed on G5 Center's Internet page this tidbit:
Pro-Tip: Tobias, key developer of Leopard-Webkit, recommends disabling IPv6 in the Network system preferences for your internet connection/port on your Mac if you experience hangs when loading webpages. I can confirm that this leads to a night and day performance change for my G5. WebKit is smooth as silk now.
So disabling system-wide sounds like a good option to experiment with. Just be aware, things like Bonjour or other system services could break, but re-enabling IPv6 is quick and easy.
Que the network IT people saying, "Don't disable IPv6. Fix your @#%^&$ing network!"
Most home networks are not ready for ipv6. Heck most of the internet is not ready for it either.ReplyDelete
Disabling ipv6 is the only way to avoid freezes in connecting to the internet via the internal airport card (and possibly external cards). Use the same procedure outlined in the article.ReplyDelete
