Gulf Coast: Possible Signal Issues?

They've re-provisioned it multiple times, no changes. I also manually logged into the modem myself and did a factory reset on it, same thing. No changes... same splitter, location, power outlet, UPS, etc. All of our TV's have been pixelating a lot more than normal lately, so much so that a channel will "lock up" and we'll have to change stations and change back to get the picture to come back. We've always had pixelating issues and have got used to it, but never to the degree it is now. 

The only "issue" on my side is that the side of the house the modem is on has reversed polarity (meaning the hot and neutral's are backwards) which isn't anything new and was this way even when I was getting 940+ Mbps download and the levels were better. It's a very old house. I'm in the newer addition of it which was built back in the very late 80's (or very early 90's) which has all 3 prong outlets. There are sections of the house that only have two prong outlets. We had an electrical company come out and give us an estimate, but they wanted to shortcut and simply install GFCI outlets (which is legal, I get it) where the 2 prongs are instead of running a actual ground. In the paperwork it also said that our neutral and grounds are connected at the panel (which was typical back when this house was built) as the main cloth feeder line from the outside panel/electric meter to the inside panel is only 3 lines (two hots and a neutral, no ground) So the outside panel itself is grounded (so I believe) but there is no ground wire running from it to the breaker box inside the house. 

Rewiring the house is on the to-do list for sure, but with everything going on in the world right now, it isn't exactly top priority, especially since this wiring has been this way for the past 60 years without issues. 

I was referring to the voltage of your signal on the coax from Cox...not your household electrical.

I thought you could only do factory resets via the recessed button on the chassis of the modem.  Is there an option within the menu of the modem?  There are 4 different "nudges" you could do with a modem:  reboot (unplug), software reset, factory reset and re-provision.

You could look for the recessed button.  However, if your cable boxes are also effected, it may be just the signal getting to your house.  How far can Cox get to your house to test your signal?

Hi CelticDubstep. Do you have an amp or booster in your house? If your TVs are pixelating, it sounds like a signal issue and we will need to schedule a service call. To do this, please reach out to us on Twitter at @CoxHelp via DM, visit us on Facebook via private message, or email us at cox.help@cox.com. Provide us the name on the account with the complete service address with a link to this thread so we can get started. - Lisa, Cox Support Forums Moderator

We used to have an amp/booster many years ago before new cables were ran (cox eventually ran a new drop, replaced the box on the side of the house, and did all new "wrap arounds" to all the TV's and Cable Modem". I still have the amp.booster but misplaced the power cord for it so I'm unable to try that for "grins and giggles" so to speak.

Thanks. I tried calling to setup an appointment but the person on the phone was extremely rude and acted if he didn't want to provide assistance and could hear screaming babies in the background (I understand people are working at home during these times, but he should have let the call roll and went into ACD status instead of acting as he did)

Anyway, I did an online chat with support and they setup an on-site appointment for tomorrow between 5-7 PM CST. 

Is it true they cannot enter the house? This is OK by us as long as they can fix the issue from the outside, but at the same time we need to have working internet as well. We've had a plumber come into the house to fix a water leak and they kept 6 feet away and we along with them had masks, etc on. We also had to have an appliance repair person enter the house to fix an appliance and same thing, they kept 6 feet away and both of us wore masks, etc. 

I have a Netgear DM1000 Modem (only, no Wi-Fi or anything) and it has a web GUI you can log into, change your password, set/change the starting frequency range, but there are also other options such as reboot, factory reset (which resets the login password back to default and the starting frequency range back to default). Doing a factory reset takes about 3 times as long as a normal reboot. There is no recessed button on the back of this modem. The only "button" is a power switch which physically "clicks" on and off. 

My router has the recessed "reset" button on the back of it that you use a paperclip and it will factory reset the device, but that is a different piece of equipment. 

I'm using my own modem that I purchased. This isn't any type of Cox Owned Equipment and I don't believe in those "all in one" units. In fact, we never could even get the Cox Panoramic modem to work when we tried to install it, nor could we get any Arris modem to work. This Netgear was the only modem that would actually sync and lock on to a signal.
