Q: Slow ping times to WAN

I have been having long ping times for a number of months.

The ping times have been over 1000 at times:

64 bytes from 8.8.8.8: icmp_seq=5 ttl=43 time=1841.476 ms

 

Setup:

     Airport Extreme 7.7.3

     MacBookPro 10.10.1

     iMac 10.10.1

     iphone, iPad, Apple TV, Roku, etc.

 

The slow ping times are both on the wired and wireless networks. Even with the wireless turned off on the Airport, the long ping times continued. The slow ping times are on all machines. I had TimeWarner out here for two weeks making sure the problem was not on their side. It wasn't.

 

When I reboot the Airport, the ping times start out at 15-20ms for the first few minutes, then the ping times start climbing up to around 500ms.

 

Any ideas, suggestions?

MacBook Pro (13-inch Early 2011), OS X Yosemite (10.10.1), Airport Extreme
