Slow Upload Speed All Of A Sudden
I have a Netgear 1900 c7000v2 modem/router (installed in April 2019) ethernetted to my PC (new in March 2019). I have the Cox Internet Preferred 250 plan (250 download and 10 upload) and normally get about 280-290 mbps download and 10-11 mbps upload. Only Cox can update the firmware, current version is 1.03.01. Recently, I noticed I am only getting 0.6 mbps on the upload. I have reset the modem, changed the port and cable, checked for updates, etc. I have good channel locking on 24 of 24 download channels and 4 of 8 upload channels. I switched to wifi and got 230 on the download and 10.8 on the upload, ie pretty normal for wifi with the other PCs/Laptops in the house that operate on wifi. So, what is wrong? Any idea if I have a mechanical problem with the modem/router, or the PC?
Not sure what specs might be useful, but:
Dell XPS 8930 (Apr 2019)
Intel i7-8700 @ 3.2 ghz
16 RAM
Win 10 22H2
Killer E2400 gb Ethernet Controller
Qualcomm QCA 9377 802.11ac Wireless Adapter
Nvidia GEforce GTX 1050 Ti
Baseboard Dell, ODF425, A00
Thanks
Seems to be a problem with Killer and Windows updates. I uninstalled the Killer Intelligence Center from the Start/Programs list, and uninstalled the Killer E2400 GB Ethernet Controller from Control Panel-Programs-Programs and Features. Restarted the PC and Speedtest has me getting my expected 8 ping, 286 download and 10.46 upload. Some folks on the Dell Forum have said Windows will keep reinstalling it. You can try and disable it in Services or Task Manager, but stopping Windows automatic updates may turn out to be the only solution in the long run. Seems Dell/Windows need to get their act together.

do you have a different wired device you could test?

Some suggestions:
Make sure your Ethernet cable between the gateway and the PC is good. Cat 6 is recommended.
Make sure you have the most recent Ethernet port drivers installed on your PC.
On the PC, check the classification of your network. It should be private and not public.
In Windows control panel, you could try the Network Troubleshooter script.
None of those suggestions have worked.

If you depend on Microsoft (Windows) to keep the Ethernet port driver up to date, recommend you go to Dell and update to their most recent driver. Make sure you download the correct driver for your operating system (Windows 10 - 32 bit or 64 bit). See attached.
So far, all indications point to an issue with your computer or Ethernet cable. Dell has some excellent troubleshooting tools available. They are the Dell Command Update and the Dell Support Assist for home PC's. As an owner of a Dell computer, you should be making full use of these tools. If you are not the owner, it is not required for you to be registered to use the tools.
