Hey guys (and gals)... long time, no talk. Not sure if anyone remembers me going to bonded DSL a few years back, but other than the past few months, it's been perfect. Very, very few problems, each pair is (10/1)*2, through a load-balancer, for a total of 40/4 for most connections (multipacket-aware).
A few months ago, I noticed lagginess on anything streaming. When I logged into each modem, the 1st line on the 2nd modem had dropped from 10mbs down to 3-4mbs. I rebooted it and it went back to 10. Since that day, that one line has been dropping to 3-4mbs every day, typically within a 24 hour period. I finally got sick of it and called CTL. They sent a technician out, who said he didn't see any problems (I wasn't home) and left a C2100T to replace the 1 of 2 C2000As I have. I got home later that night, listened to his voicemail, and set up the new modem. It didn't help.
So I called again, a few days ago, and the guy who originally set me up came out, vs the younger guy who wasn't familiar with my setup. He's been awesome, but he's been skeptical of the viability connection from day 1, despite it running for over 2 years without any major issues. He says my loop length is just too long. Of course, I came back with "Why has it worked for 2 years without issue?". He said he would keep an eye on it over the next few days.
I saw him a few days later in the neighborhood. Turns out the night I talked to him on the phone, he "bounced the port" (that is the actual term shown on his DSLAM mgmt GUI). After that, the lines were fine for about 5 days... something that hadn't happened in the past few months, as I've needed to reboot once a day. He said I could call him and he'd bounce it again. If it kept up, he'd replace the port.
My question is, can ports in the DSLAM just go bad, or could it be something else? I've gone over my lines in the house, and I'm pretty certain there are no issues on my end. I've yet to be able get ahold of him since seeing him at the DSLAM, so this may simply be conjecture, but I'm curious.
Additionally, I'm seeing some disparate readings in the two different modems in regards to loop length. I believe he's told me I'm at around 5000ft. The weirdness is the two lines on the first modem say 4910 and 5080 for the "estimated loop length", while the same stat on the 2nd modem (same physical distance) say 9456 and 9096. If it were only a few percent off, I'd chalk it up to a margin-of-error, but the 2nd modem actually shows nearly TWICE the loop length. How is that possible?
Also, when I first set this whole thing up, I ran the following commands, which as I understand, raise the tolerance threshold of the modem... though I'm not 100% sure how that works, being as though the ASSIA software seems to be the culprit in regards to my speed dropping.
Here are some stats from my lines, a few minutes after a fresh reboot of the 2nd modem:
**EDIT**
There are a ton of stats for four lines... I'll put then in the following posts
