Comcast upload speeds very slow, but download is good
Have a netgear C7000v2 modem. Purchased in May 2020 (8 months ago) and have noticed really slow upload speeds lately. Comcast is my ISP, and their speed test reports ~650mb download on average, but u...
Dealing with that now any Solutions with that problem
No, multiple tries with Comcast have not resolved the issue, and nobody else has replied here with anything to try. I think Comcast is dancing around it and doesn't want to solve it because it's a DOCSIS 3.0 modem even though it will support 140mb upload speed. Have done regular reboot, factory restore, tried all kinds of solutions but none work. It has to be a problem on the Comcast side but I have no other choice in ISP with 25+mb download that aren't garbage (satellite).
Ended up buying a new modem with DOCSIS 3.1 and getting normal full speeds as expected. The tech that came out also checked the lines, said they would support full speed, confirmed that my modem had the "default" boot files for it, which means it was throttled intentionally by Comcast despite the modem being capable of higher bandwidth speeds. Ridiculous, but that's what they can get away with; no other providers in the state have service over 100mb speeds and they know we don't have any alternatives.
