I have been having issues for a couple weeks now and have narrowed it down to my airport extreme. Let me start by saying I have done testing from my Linux box wired, PC wired and MBP both wired and wireless and they all have the same issue so I am sure it has nothing to do with the wireless part of the network. I have tried to remedy the issue with lots of restarts and tried to upload the same firmware again but nothing seems to help. The only time it is better is right after a restart, the first few pings/traceroutes are always normal speed but within 10-30 seconds it's back to extreme delays again. Here are the traceroutes that I have done now that I have it narrowed down, done some with airport and some without, definitely something with the airport. Other router/direct connect are always ~10ms ping to the second hop: 1 192.168.0.1 (192.168.0.1) 1.760 ms 1.601 ms 1.765 ms 2 10.118.64.1 (10.118.64.1) 10.330 ms 13.940 ms 10.756 ms 3 ip68-2-6-65.ph.ph.cox.net (188.8.131.52) 11.863 ms 9.250 ms 9.841 ms With Airport times are always 350-800ms: 1 192.168.0.1 (192.168.0.1) 1.795 ms 0.720 ms 0.754 ms 2 10.118.64.1 (10.118.64.1) 641.414 ms 639.033 ms 672.026 ms 3 ip68-2-6-65.ph.ph.cox.net (184.108.40.206) 589.582 ms 679.694 ms 457.916 ms Anyone seen this or have any other ideas to save me a trip to the genius bar?
