Well, the difference between Corrected and Uncorrected tells the story. It's now 0.
SNR (Signal to Noise Ratio)
This is how clear the downstream signal at your modem.
For 256 QAM
Minimum: 30 dB
Recommended: 33+ dB
Before/After
• Before, you had averaged almost Minimum at 36 dB
• After, you had averaged better than Recommended at 44 dB
• You gained an average of + 7.34 dB
Downstream Power
This is the amount of signal from Cox to your modem.
Recommended: - 7 to + 7 dBmV
Acceptable but out of spec: +/- 8 to +/-10 dBmV
Maximum but out of spec: +/- 11 to +/- 15 dBmV
Before/After
• Before, your Power appeared to be within spec
• After, your Power still appears to be within spec but gain an average of 3.60 dBmV
If anything, your signal got clearer.
Ingress is just a perceptive. If you're testing on the Cox network (outside your house), ingress would be noise coming from your house onto the Cox network. As a Cox tech, I'm sure the tech would call it ingress.
If you were testing inside your house, ingress would be noise coming from the Cox network onto your house. The tech said your house is creating noise. Just to be clear, the previous tech(s) did not detect or report ingress?
Was this ingress before or after your husband bypassed the splitters? Meaning, what was connected inside your house...just the modem and speed-testing laptop or everything? I think the tech tested before your husband tested.
This appears you have faulty splitters. Others are much smarter at this than I, so let's see what they conclude.

Lol, once again, I had a whole reply and I keep losing internet. Once, right as I hit send, so I am having to retype everything lol. This might take a while to get posted lol.
You were correct in that the previous tech said that everything looked good when he tested.
The modem logs that I posted were after hubby bypassed the splitter but before the tech got here and we only used 1 computer.
Now, hubby did bypass splitters BEFORE the tech came out today and we left them like that for the duration of the testing when the tech was here (which he reported ingress).
After the tech left, hubby had to get back to working so I hooked the router back up. I should have made a copy of the modem logs before I hooked up the router, but the uncorrectables were starting to show up prior to hooking up router, but in low digits and they weren't in every channel yet like they are now.
Now here we are a little over 4 hours since a modem reboot and the uncorrectables are climbing again. I don't know if that's normal.
For the record, we are still bypassing splitters at the moment.

Ok...4 hours later your signal still looks in specs.
Correctable and Uncorrectable identify packet loss. You will always have some errors unless you live next door to Cox. Correctable is the number of packets corrected. Uncorrectable is the number of packets so corrupt your modem had to request a resend from Cox.
Uncorrectable are your most concerning. You'll typically see 1 or 2 channels with high Uncorrectables due to interference from specific frequencies.
You, however, have Uncorrectables on all frequencies, so something is causing interference.
Since a couple months ago, did you install new electronic devices in your home? Hammer any nails into a wall? Has anybody inspected the 4-foot segment of coax flapping in the breeze outside your house for wear, tear, chaffing?
When you or your husband were in the attic and aside from the 4 segments of coaxial cable and 2 splitters, did you notice any other electronic components, such as an amplifier, filter or tap?
- JillPill3 years agoNew Contributor
Ok. Hubby says he did not see any electrical components in the attic. There's really no new devices in the home either. Only a smart plug that I only use during Christmas for the tree, but I did a whole device elimination test even prior to the plug since I was already having issues. I actually did some wifi device moving the other week because the tech that was out here said maybe I had too many devices on one channel. (I laughed because I had a total of 9 devices spread across 3 channels at the time, but I removed them and added 1 at a time anyway to be sure)
I believe the tech today took a quick look at the 4 ft section of cable outside but I know hubby did as well and he didn't see anything that stood out.
Hubby is going to try and make a run to home depot tonight or tomorrow to get the high performance splitter like Mouth suggested cuz it looks like from Amazon it wouldn't get here until next week. Hopefully that will fix one of my issues.
I am trying not to get too frustrated with all this. It's just crazy to think everything just blew up all at once, when everything was working all good a couple months ago.
I really appreciate all the time yall have taken trying to help me, so please let me know when I have worn out my welcome lol.
