Recent Packet loss CT jan/feb '05
Anyone in the Hartford, CT area experiencing new packet loss in the last several weeks? I've gone from consistent 2500Mbps/100Mbps to 1700Mbps/2Mbps, yes 2Mbps... reset all hardware multiple times. ...

I assume your not using wifi if getting 2Gbps+ speeds. What model modem and router/other do you have? Does the problem go away if you connect direct to the modem? Can you post your modem's signal levels? If a stand alone modem, you can access them at 192.168.100.1. I can give specifics once I know what kind of modem you have. Last, do you know of anyone else in your area having the same issue?
First thing I notice is your downstream power levels are a bit on the high side. Spec is -15 to +15dB but optimal is -5 to +5dB. Are you going through a amp? Next thing I see, or rather what I don't see, is the OFDMA channel in the upstream channel data. Does it show in another part of the diagnostics maybe? That is important because it is needed for the higher 100Mbps upload. Next, I notice 4 T3 time-out errors over the last few days. That is typical of a intermittent ingress issue with the upstream signal. Last, the Event type code 5/24 is the recovery of a QAM/OFDM channel. What I don't see is the usually matching code 2/25 when the channels fail to begin with. See here for more info.
When was the last time you had a technician out? Have you ruled out everything on your side past the demarc(where coaxial connects to your electrical ground)?
I've had this service for over a decade with various modems and aside from occasional outages never had a hardware issue. This has only been since I upgrade to their 2G about 3 months ago, issue started with their issued gateway/router, which wasn't user configurable. I'll try swapping another modem and then have a tech out. Frontier Fiber just went in across the street so they better up their game honestly...
Thank you for the troubleshooting and insight :)
Almost never is the modem. Your main issue is upstream speed failing sometimes right? Well a signal issue causing the upstream OFDMA channel to fail might cause that and would only show after upgrading from a DOCSIS 3.0 device to a DOCSIS 3.1 device. If you have covered your side, hopefully the problem is happening when the technician is there. Good luck.
As happened last time the problem resolved itself magically at 8am the next morning...
Check your signal levels. Did they change? Do you now see a upstream OFDMA channel?
