I wired the Cat5 in my house seven years ago. The wired ports have worked fine with both my Windows XP laptop and MacBook. My wireless network also works fine, but I like to use wired occasionally.

One of the Cat5 runs wasn't terminated with a jack, so I recently terminated this wire with a port/jack on the wall end and a standard Cat5 plug on the end that plugs into my router. This is the same setup as my other runs.

Unfortunately, the MacBook isn't working well with the new wired port. The OS X Network System Preferences show the IP, Subnet, Router, etc., and everything looks fine. A "netstat -ibd" shows no errors or dropped packets. However, when I open a page in Safari, the status says "Contacting 'www.google.com'" and appears to hang. If I wait for a couple minutes, part of the Google page starts to display, but it is still not the full page load.

When I use a Windows XP laptop on the same wired port, everything works fine. An internet speed test shows good results and all web pages load fine. A "netstat -e" under Windows shows no errors.

I've used a Cat5 tester, and the cable tests fine (wires 1-8 light up in sequence). I've replaced both the port/jack and the connector twice to make sure I wired things correctly.

I'd really like this Cat5 to work with the MacBook (and I'm trying to avoid running a new length of cable). Any ideas what the problem could be?
