C7000v2 Speed Issues
Hello, Recently we were told by our ISP (Spectrum) that our Internet speed has increased from 100MB to 300MB. Not only did this not happen, but our upload speeds are now nonexistent when connected v...

Thanks FurryE38.
Well I have an update! Spectrum came out and replaced the line due to errors they saw, but it didn't resolve my issue. HOWEVER, they tested with the ethernet cables I was using and verified upload speeds worked fine ... so it isolated my upload issue to the PC. After researching extensively further, I discovered that people have been complaining for months about the "Killer" ethernet software that a firmware update caused it to kill upload speeds :). There's literally a single switch in their control panel you can punch to fix it, which I did. So Netgear is off the hook officially on this one :).
On the WiFi side, uploads have always been fine. The download speeds bumped up tonight after the improvements, but still not to 500mb ... its stuck at around 300-350. Well I was told by Spectrum that despite my device being able to handle 1.9GB, Spectrum only supports up to 400mb on that device, so that is tracking with what I'm seeing. I was only aiming for 300 in the first place anyway. Strangely, the PC that's physically connected is still well over 500mb regardless of what they say.
So bottom line the mystery is solved ... partly a line issue, partly a software issue. Thank you for the help in thinking this through FurryE38!

I highly recommend next time, of you do have to get something different, go with separate modem and external wifi router systems. So if something happens to the modem, you still have a router system you can connect up to a new modem should something happen. And you can have more control over the FW upates on the router system as well. C and CM series modems don't allow for user FW updates.
Good Luck.
