I've had this same problem since Oct. 2010 I live in Eastgate Woods and I've ran multiple tracert's and this switch is the same one I've had problems with. Cinbell says that that switch prioritizes all traffic over ICMP thats why it looks to be loosing packets and times out during traces. I don't believe it but what can we do. I've had 10 techs to my place and the last one said that if moving me from one circuit to another to just move that would be the only way to fix my problem.
This is a line test I ran back at the end of Jan. but yep nothing wrong here.
