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.
Thanks FurryE38.

Glad ISP helped on there side.
Ya Killer adapters have been historically one cause of posters issues for those use them. Killer has there own QoS features that seems to either not work as intended or not work with other router systems that already have QoS features running. Usually disabling the Killer QoS features fixes it or getting into a non Killer adapter resolves.
Ya, depending on wifi device design and support and this model modem, you'll not see much over 300-500Mbps on 5Ghz AC. Just nature of the beast and limiation of working with 2x2 MIMO and 80Mhz channel width.
Glad you got it working. Please mark your thread as solved so others will know. Be sure to save off a back up configuration to file for safe keeping. Saves time if a reset is needed.

Enjoy. 📡Thanks again Furrye38, and thanks again for this (and the earlier) helpful links!

Tim and Marilyn: What is the "single switch in my control panel to fix slow speeds for a NetGear AC1900 C7000V2 Modem-Router? Thanks

Hi swingtime! It is the "Prioritization Engine" - literally just turn it off and the issue is resolved. Well, sort of. Apparently the option turns itself back on after a reboot, so I've still got to figure that out. I've read that some people are just uninstalling the Killer dashboard and just using the base driver.
