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 via a physical cable (upload speeds are fine via wifi, including on the same PC).
For context, we bought this in 2019 specifically to be future proofed for speed upgrades like this. The C7000v2 can handle well above even Spectrum's increase, yet it's not working. We are on firmware V1.02.09, the one supported by Spectrum (according to this: https://kb.netgear.com/000036375/What-is-the-latest-firmware-version-of-my-NETGEAR-cable-modem-or-modem-router?article=000036375).
We've done the whole router / PC reboot thing a few times to no effect. I called Spectrum and after some testing they show the correct speed being pushed out. They say it's a Netgear issue. Any recommendations?
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!

Has a power off for 1 minute then back ON with the ISP modem been performed?
Be sure to restart your network in this sequence:
Turn off and unplug modem.
Turn off router and computers.
Plug in and turn on modem. Wait 2 minutes for it to connect.
Turn on computers and rest of network.Please post a copy and paste of the modems connection status and event log page.

https://kb.netgear.com/30008/How-do-I-view-or-clear-the-event-logs-on-my-NETGEAR-cable-modem-or-modem-routerThank you very much for replying! I have not tried it in quite that exact sequence before so I will give that a shot to see what happens. To clarify, this is a gateway device so there isn't a separate cable modem, this is an all-in-one device. I may have to wait a day to do it but I'll reply here when I do with the results.
Yes. There is a built in modem though.
What "single switch in the control panel did you punch? Thx.

- Hi swingtime! I actually answered your question- see the reply right above your most recent post.
I do not see a "Prioritization Engine" switch of any sort on my netgear http://192.168.0.1/ dashboard page. Is the switch in my computer control panel? I have continued erratic and SLOW speeds via my C7000 modem-router the past few weeks.
I need level 101 help! Thanks
