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!
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.

Thank 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.
Hi FURRYe38, unfortunately that did not work. Specifically, I powered off the NetGear, shut down a PC and laptop, and turned off two phones. I actually disconnected all cables from the NetGear and waited five minutes. I reconnected all cables to the NetGear and let it fully boot, then turned on phones and laptops. Same results. To summarize again:
- Download speeds top out at just over 100Mbps on all devices, wired and wireless, when it should now be increased to 300Mbps.
- Upload speeds are 10Mbps on all devices (which is correct), except the PC that has a physical connection. For the PC, uploads don't work anymore - speed test shows as 0Mbps. If I disable the physical port and enable Wifi on the PC, uploads are 10Mbps.
I have tried two different physical network cables, and I have tried two different ports on the NetGear with the same results.
Any other recommendations? I'm planning to call Spectrum again as I'm on the latest approved firmware by them.
