Hey all, need some advice as something doesn't seem right.
I am on the extreme tier, and was getting an awesome, consistent 90+ Download speed.
Last week we had a lightning strike very close to the house. as fast as you just read that. The only thing damaged in the house was my cable modem (6141) and my wifi router (AirPort Extreme) so I believe the hit came down the cable line. I had a spare router, but the cable modem was completely dark. Dead Jim.
I ordered a new 6141 from Amazon, it arrived, plugged it in, provisioned fine. All eight channels bonded good. Signals looked great (9-10+ and 38 signal to noise), almost identical to the now dead modem. But when I would go to download test, it would barely register ONE Mbps. Usually 0.5 to 0.8, a far cry from my previous 90. The test looked jerky. Uploads OK at 10. I replaced the cable from the drop to the modem with RG6. No splitters, nothing. Straight from the grounding block to the modem. No difference.
Comcast thought I had a fried drop, so a tech came out today. He replaced the entire drop from the street and tested the signal at the ground block and in the house. Everything looked great on his very large docsis test device. Still, super slow speeds. No channels stood out as low or error riddled. It just looked normal, but no speed.
As a last resort he got a modem off the truck (ubee) and provisioned it. Speed then jumped to 35mbps. I see it's a four channel modem. Still, that modem should be able to give me 90 as well, right?
The tech gave me the "well speeds vary and 35 is pretty good" speech. He believes that I simply got a bad 6141 but it doesn't make sense to me. The modems are apples and oranges, one being an 8-channel and one being a 4-channel.
To my skeptic nose, something still stinks. What do you think?
