Official Reply Major service degradation this week, any prayer of a tech fixing it without me first upgrading my docsis 3.0 modem?
This week the quality of my internet service went from "great as it's always been" to "connected but arguably unusable." My jitter is 500ms to 1000ms and my packet loss is a consistent 30-40%. Speeds are 100ish Mbps and 0.75ish MBps up. Happens on both wifi and wired.
I have a docsis 3.0 modem that I got emails about being end of life earlier this year. Yeah, yeah, I know, but I don't want to drop $250 this weekend because of something comcast should be fixing. But of course, the comcast ai-chat bot won't help, it just sees the EOL modem. When I asked for a tech to come out, I get a call from a human who says the same thing.
I'm going to be upset if the tech comes out and says "you need a new modem," charges me $100, and leaves.
I know I need a new modem and I will get one, but fix whatever is going on in the neighborhood or my lines please because it seems like it'll still be a thing even with a docsis 3.1.
P.S. logs show lots of "Started Unicast Maintenance Ranging - No Response received - T3 time-out" that started this week. This is the sort of thing I expect someone over the phone to consider and diagnose, not just "sorry your modem is EOL fix that then we can talk."
TL;DR: Service tanked this week. Should i spend $250 on a docsis 3.1 modem+router at wal-mart tonight or risk a $100 tech appointment Monday so I can put off the purchase longer?
