About 7 months ago I upgraded to TWC Roadrunner 40/5mbps which required me to upgrade to a DOCSIS 3 modem. Unfortunately, at the time all DOCSIS 3 (That weren't super expensive) were only sold to ISPs so I had to rent from TWC. They gave me an Arris Touchstone TG862.
I now have it in bridge mode due to not liking TWC's extreme policing policies on using rental modems/routers if you're not a Signature subscriber and the router portion didn't support dual-channel and I wanted it. So I switched over to my old Linksys EA2700 router.
However, I am having an issue with downstream channel bonding. The modem used to bond to all 4 channels, now it only bonds to 2 channels. My SNR and power levels are all well within acceptable ranges and I bond to all 4 channels upstream. When the modem was new, it was always bonded to 4 channels, and it started only bonding to 2 and occasionally bonding to a 3rd every once in awhile but quickly dropping it a month or two ago (Before I threw it into bridge). I also have a lot of FEC errors on downstream with a pretty high ratio of uncorrectables to correctables. Unfortunately, I'm not at home right now and the only way to access the modem's HSD diagnostics is to directly connect to it (Downside of bridge mode on this modem). The error log has many RCS partial service and lost MMD timeout events. Many every minute.
I've noticed, starting a few days ago, every once in awhile my connection speed would flatline at about 0.75mbps for 5-10 minutes before regaining full 40mbps with upload remaining at the full 5mpbs. Never fully dropping out, just getting very slow.
Is the slow speed due to the channel bonding issue even though I haven't noticed slow speeds that often prior to a few days ago? Tomorrow I'm gonna try to chat with a level 3 TWC tech, find out who's end the problems is on. Just wanted to see what you guys think. Thanks.
