Upload speed Issues

Question

I've been having issues for a couple months with my upload speed dropping. I had a tech out today and he resolved an issue in the line and fixed the power levels on the modem, but the upload issue still persists. After he left, everything worked perfectly for an hour before the upload speed dropped back down to under 1mb/s. I enjoy streaming online games and an upload speed that slow is unacceptable! Before today the power levels on the downstream bonded channels were -22 -&nbsp; -23 with high codewords on certain channels. Now I'm curious about the Downstream OFDM. I don't know the range it's supposed to be operating in or what effects it and don't know how to fix my issue. I think I might have the wrong firmware on my modem as well. On my end it's&nbsp;Firmware Version&nbsp;V6.01.07, and from what I understand it's supposed to be 3.01.04? Should I factory reset my modem? I have Gigablast with a Netgear cm1000 modem.

Could the issue be old wiring coming into the house? I'm running out of patience and if I have to deal with customer service one more time I might lose my sanity.

We can attempt to push a firmware update to see if this will help, though V6.01.07 is approved by Cox. If issues arise after attempting a firmware push, then you may need to perform a factory reset to your Cable Modem. Do you have a signal amplifier attached to the coaxial cable or is there a splitter or barrel attached to the cable?

The modem is connected directly to the wall. I had a tech out here yesterday and he bypassed the amplifier coming into the house (recently canceled TV service and the amp was causing noise in the line) which seemed to fix the issue for about an hour. I called NETGEAR a few days ago and they said the firmware for Cox should be v3.01.04.
If I do a factory reset on the modem, will it update automatically when I reconnect it or do I have to get ahold of Cox to get it updated?

whosta · Answer

I went ahead and did a factory reset on the modem and it did update automatically to v6.01.07 firmware.

This is the event log on my modem

@whosta

Are you hardwired directly to the modem, router, or VPN?  If not hardwired directly to the modem please bypass, reset and check the logs.

whosta · Answer

I have the same issue regardless of connection (hardwired, or router) and I do not have a VPN. I'm convinced the issue is on Cox's end. Something in the neighborhood needs to be replaced or updated, or somebody connecting to the same node is using up all the bandwidth. I don't want to go through the hassle of having a tech come out constantly to say everything is "running perfect" when it's clearly not and they are aware of it. I'm not a tech wizard, but I'm at least smart enough to know how to troubleshoot my own equipment to see if it's faulty.
