When my instructor app shares, my connectivity status changes to poor and her voice becomes sporadic

I learned last night that the firewall I have loaded -- McAfee Secuirity Suite --  may be causing my issue.  None of the other 30 participants in the class are using McAfee and none of the participants are not experiencing my problem.  I've uploaded Windows Essentials and turned off McAfee for tonight's training.  I'll re-post this evening to let y'all know if this fixed the problem. If this doesn't work, I'm out of ideas.

I am having the same problem as the person above.  I have been working with my DSL provider for 2 weeks and have been unable to find anything that is causing the latency problems (although my DSL service has improved overall with the changes that were made).  When I connect via my Verizon aircard, everything works great, but I will rapidly start getting charged for data overages in a week.

Because the aircard worked great, this led me to believe it was a problem with my DSL connection.  I have done trace routes and there is no consistent issue with slower ping times or packet loss.  Yes, I get the occasional 200-250ms ping times on one hop, but that is not unusual due to the reduced priority on ping traffic (ICMP, I think).  Anyway, then I learned that routes are not always symetrical and that the return path may be different than the outgoing or request path.  And the return path seems to be where the issue is.

How can I work with someone to troubleshoot my return path from adobeconnect.com?  Can someone do a traceroute to 68.22.72.67?  That is the hop just before my router.

FYI, here is what else I have done to try to narrow down the problem:

- use aircard and it works perfect, but that uses a different path which leads me to believe the path is the issue

- turn off all other devices connected to the router

- trace routes, endless ping tests, pathping, speedtest.net, pingtest.net, all tested good

- bridge tap was removed lessening my distance to the CO from 9000 ft to 8000 ft

- replaced corroded connectors

- reprovisioned line to the red back (ATT's term)

- changed pair from the CO

- attempted adobe connect sessions on multiple computers with both Windows 7 and XP

- instructor reduced connection speed from LAN to DSL and reduced frame rate at my request with no change

- she records the classes and the recordings are perfect except for the times when the class pauses.

The latency I am experiencing is when she shares a screen and then it can go as high as 8s, but mostly it is between 2 and 4s.  That is enough to make the audio completely drop out or it is just uninteligible with the short bursts that come out.

Please help.  If you can help identify where the problem is in the return path, I will attempt to take it from there.  Scott
