Re: Latency and Packet Loss Problems - Over 2 months

kelfa See Profile, please do not "append" to the thread. I'm not picking on ya (honest), but it's very important people remember:

Every single issue/ordeal needs to be handled individually/separately, at least initially.

When a thread/issue of a single customer begins to result in "me too" posts, it becomes difficult (bordering impossible) for an ISP or any technician/engineer to get concise details. Literally one engineer could spend 2-3 hours of his time every day just trying to sort out who said what and what means what. The official Comcast forums are *filled* with this sort of thing, which is almost certainly why it seems like nothing there ever gets responded to + fixed.

I would strongly suggest starting a separate thread here on the forum for your issue, and if you want it's cool to say "It's very similar to {this thread here}" but please keep it separate. You will need to post signal levels and do the exact same sort of analysis as what was done here. Don't post "summaries", post actual hard data/evidence.

In TimHaag See Profile's case, at this point it looks like something very close to the CMTS, and I would be surprised if people multiple hours apart were using the same CMTS. If this was a "Comcast backbone" (IP network) problem of some kind, it would be showing up starting at hops further away (i.e. hops #3 or #4), but it happens very close to home. My first inclination is an oversubscribed CMTS, but that is purely speculative and it is impossible for me to get evidence proving that at this time. We need to wait for jlivingood See Profile or other actual engineers to get involved -- and if they do not get involved, there are other options available, but as I told Tim privately, I don't' want to jump the gun.

Any update on this situation ?

I am very curious to know the resolution ( yes, I am and have had for over 6 months this same issue -yes..the same exact issue...we could swap usernames and the details would be 100 percent the same...except im in pt charlotte, fl)

and no, that wasnt a "me too" ...just a heads up that comcast has this same problem in another area of florida

It seems almost systemic and more than just any given geographic service territory -- chronic and/or intermittent troubles are very difficult if not impossible to have addressed or followed up upon. Why? I think its because there's no real "ownership" of such problems. Just keep closing out the tickets & sweep 'em under the rug hoping it'll go away or maybe the customer will bail and go bother some other broadband provider (assuming they even have that as an option).

My own experiences -- nearly identical to what you guys enumerated -- have been posted here on DSLR. ~3 months later the problem still exists and we're on the 11th or 12th dispatch now.

Just know you're not alone and in good company guys... Be persistent and don't give up.

Sorry I didn't update sooner. The problem still exists. I had about a 2 week reprieve during the holidays, but am back to daily packet loss for 4 to 8 hours each day.
