VERY low upload speeds for past few days
We have had very low upload speeds and intermittent stalling of downloads over the past few days (7/19 - 7/21-23) in the Hampton Roads. VA area (23320 zip). Speed test results have varied from 40-22...

BTW, I read your previous posts and saw you said you had a NIU on the side of your house? Is it still there? If so, get a technician out to remove it and replace it with a demarc enclosure box. See thread here for a simular issue, but it effected download and not upload.
What is an NIU? I have an entrance point box that was used for my prior copper land-line phone service (Verizon) and a smaller Cox cable entry point box, both on the side of my house. Will read through that thread, thanks,
Maybe I read your post wrong. Only glanced through it.
What is an NIU?
NIU is Network Interface Unit. It was for Cox's older circuit switch technology before they changed to eMTA for VOIP. See post here for more info.
a smaller Cox cable entry point box
Is that where your demarc is with your splitters to split the signal to other outlets in your house? Also, any problems with TV service like issues with OnDemand?
Overall I would suggest bypassing the router first and see if your upload speed returns. If not, try bypassing the splitters in your house with a coupler to see if that corrects the issue. If not, you need a technician.
Okay, bypassed the router and got 215/0.40 speed, so better download and no upload improvement. Oddly, downstream power level is now reading +1 (previously +7) at the modem info page (192.168.100.1). The modem info page log tab shows a series of "No Ranging Response received" messages. In the status tab of the modem info page it actually says the cable modem status is "offline" even though it is connected and loads web pages. Also of note is that any access to the modem info page stalls for about 20 seconds (I remember the info popping right up in the past).
Another speed test now shows 188/0.18 down/up speeds.
The cable service enters the house at the Cox box on the side of the house and goes up to the attic. In the attic there is a new +15 db single output amp (added in March due to low signal levels) and after the amp are splitters feeding the internet, TV, and phone devices in the home.
