Over the weekend I noticed that browsing in Safari and in Firefox was significantly slower than normal and since I had upgraded my Powerbook to Mac OS X Tiger, I figured it was probably a bug and Apple would fix it in 10.4.2 or some other update. However I started to look at it and see if I could fix it myself.
Apparantly some OS X Tiger users have been recommending that you disable IP6 in your Network Preferences, which does seem to work, but I’m not sure how long this lasts or if it is the actual fix or not.
I decided to spend some time tightening up my Netgear wireless router and noticed that the router setup did not have my ISP DNS server ip addresses. I corrected that and then in OS X Network Preferences I put the ip address for my router and that seemed to fix things and now browsing is back to normal.
The bug must be with the DNS settings, it must some how not be sending them through the router correctly, like it use to on Mac OS 10.3. Hopefully Apple will fix it soon.
