The location is west of Charlottesville; the issue is a once extremely reliable service circling the drain. In over ten years I’ve experienced a handful of downtime or sync issues, and always received a full 10M down. Noise levels were good - 15db down and up - and steady, with attenuation running 20-24.
After dropping the landline to save money there were some hiccups, but still good service. However, in the past couple of months the issues have skyrocketed. I also now sync at half my rated speed, and routinely have issues maintaining sync for a day here and there, and then it will clear up and stay solid for awhile before repeating this cycle.
I thought perhaps a line issue as rainy days made it worse, but it rained all last weekend and the service didn’t go down as it did the previous rainy spell. Also, at some point the 911 service I was supposed to have on the line wasn’t there and then returned, so something was going on. I've also pulled a new IP on a different netblock from what I was on for a very long time.
I finally called and because CL no longer supports my modem (660) I get nowhere other than they report no issues in my area.
TS is adamant a new modem is what I need to fix the problem, but I’ve heard that before and when I’ve had perfect service.
When the service acts up, I’ll log-on to the modem and watch the noise go from 0 up to 20 db and back like a yo-yo. It will sync up with a 20db downstream level and then I'll refresh that screen and watch the signal nosedive until it drops.
I’ve synced as low as 2.5M with a 4db downstream noise and stayed online for hours with that noise level. Attenuation usually doubles during the bad spells, up to the high 40s. The attenuation is 37 right now with a 13db downstream noise / 10 upstream, from what used to be mid 20 attenuation. I’m synced just under 5m down and a terrible 200k up but it’s been solid like this all weekend.
The only correlation is that a couple of homes near me hooked up with CL right about the time this all began. I know this from the dishes in the yards and the new drops to the houses. Also, the number of visible access points has gone from none to two.
Before I bail out and call Comcast I was going to take one last shot and buy a modem unless someone can talk me out of it. I should take my modem to the NID but I’ve done that whenever there was a lasting problem and it was never the house line, which is a single line run from the NID around the house and into the room to the 660 modem. I have another 660 but it won't sync. It used to, so I don't know if they're using MAC addresses now or if that modem crapped.
TIA for any replies, and I apologize for the long post.
