Modem To Patch Panel

[Lane Stefano]

ModemPanel Comm Error indicates that your security panel is unable to properly communicate and may not receive signals from your devices and may not trigger an alarm or signal for help in an emergency.

Thanks. I ran a manual cell test and it passed before I saw your post. Now the sensors appear to be communicating, and the bypass I set has cleared. Strange glitch for sure. Should I still power cycle the panel?

Older panel, I believe. Nothing under the emergency button. I did pull the power on the ADT panel, but it and the Take-345 are on battery backup. So seems to have resolved spontaneously. As a pilot friend of mine said flying a Grumman Goose over an Alaskan Glacier, I worry about problems that fix them self.

I first tried the Manual Cell Modem test, it failed. Then as Jason mentioned I powered down the panel & unplugged the battery. 2 minutes later I powered up and ran the manual cell test (passed). The problem seems resolved.

There are a great many possible causes. From the description of what you did however it was likely an issue with a tower connection. Powering down for 2 full minutes forces the module to re-register. Signal Strength looks otherwise very solid. Let us know if you do notice it again though.

So my setup before I changed it had a Arris Cable modem from Suddenlink, a AC1900 Router for wifi (Wifi was turned off on the Arris Modem) I connected a cat5 from the port of the modem to the "internet" port of the AC1900. I was able to connect wirelessly to the AC1900 and be able to access both the router and the modem (192.168.1.1 and 192.168.0.1) I recently changed from wireless to hardwired on my gaming tower, Which I ran directly to the modem. Now I cannot access the AC1900 either between 192.168.1.1 or routerlogin.net. I have the router set at 192.168.1.1 due to some devices needing to be in that ip range. I cannot change the settings of the modem as it's locked from the provider.

Try a factory reset on the router. Reset the modem also. Then disconnect the wired connection between the router and your gamer and see if it still connects the old way. It should work the way you have it but sounds like something wierd is going on.

I changed the IP of the R7000 to match the range of the modem (192.168.0.X) I just have to get the wallpanels and security system's IP's changed which is a pain in the butt as they like the 192.168.1.X range

But to be fair to people who have not learned how to use the Quote button, and where to find the HTML toggle, the forum software does some funky stuff when it comes to word wrapping. I see too many messages that break the margins. I don't think that is user error.

Was it setting the IP address that made things work for you? You could help later victims by flagging your explanation as Solved. That makes it easier for people to home in on solutions,

Initially I hooked up the coax cable directly to my cable modem (Motorola MB8600) as straight down as possible (to avoid bends) to the left of the circuit panel (see picture below) but the cable was close to several thick power cables just to the left of the circuit panel.

So I tried to bend the coax cable and putting the modem as far away from the circuit breaker and got a VERY DIFFERENT result. After 24 hours, my modem shows 0 errors except the 732MHz OFDM PLC band which still has a lot of corrected errors, but only 0.00006% of them uncorrected. See screenshot below:

I noticed that in the new location, the power level and the SNR is a lot better, which may explain the improvement in errors. And in between the two locations, I have disconnected the cable from the modem to perform some other experiments, but I think I screwed on the cable to the modem with equal tightness.

Addendum. Before I moved the modem to the basement, the original location of the cable is marked by the red line, and the cable from the outside terminates in a splitter that is also grounded. See picture below (red line traces where the outside cable used to go):

A short cable from the splitter extends it upstairs, through a coupler (second red box above), terminating in a wall jack in a room directly above the current location of the modem (so it is a short cable). Another cable connects the wall jack to the modem inside that room. With this set up, the errors in most channels were better, but still significant. See screenshot below:

I thought the splitter and/or the multiple cable segments was the culprit, so I bypassed the splitter by moving the modem to the basement and connecting the outside black cable directly into the modem. But several users commented that it's the modem's proximity to the power panel that is the culprit, so what I'm going to do next is to move the modem back upstairs and connect the outside cable directly to the coupler as far away from the power panel as possible.

From one of your pictures, you say that your modem was very close to the power panel. The power panel emits the largest amount of EMF than most items in your home. Too much EMF too close to your modem definitely causes interference resulting in a large number of errors.

In my case, I had two routers next to each other and that was enough to cause many errors. Moving the routers apart by about 1 meter was sufficient to fix the issue (EMF levels drop quickly with distance).

The coaxial cable emits a really very small amount of EMF. First it does not use 110V at 15A, but it is also built in a way that reduces outward emissions and it also protects the signals by blocking incoming EMF, to some level. That is, if the EMF level are really high, it will still disturb the signal. However, many coaxial cables running next to each other, should have no issue since their signals are self contained.

One problem, for coaxial cables, is that everything has to be as symmetrical as possible. The build and the current used within the cables. I would think that your cable company would have a lot of problems with they did not probably pretty good cables and signals. But it could be somewhat lower standard and if the cables are not that great, placing them close to a large EMF source (i.e. your power panel) will also affect the cable. For the power levels within the coaxial cable to not be equal would sound really strange. It should be really easy to keep it the same for the small distances we run those cables to a house. So I would not worry about that part.

The total power draw from the connected devices, including the 0.5 amperes used by the inverter equals 1.65 amperes. If my math is right, the 75 amp/hr battery should power the modem and router for 45 hours if the battery were allowed to drain completely.

The panel itself is not in an optimal position. It probably misses 3 hours of morning sunlight, then maybe another hour or two of late afternoon sun due to its location on the ground. It's also not properly angled.

Solar panels connected to a battery pack can be a great system, but the current cost for solar panels really puts a robust system out of reach for a lot of people. The solar industry says $1.00 per watt is were these systems need to be in terms of cost. I'd like to see half that. A 3,000 watt non-battery system that ties directly into your home grid for around $3,000 with an inverter (not including labor costs) would be fantastic.

As for my little system, it's a lot of fun to have even a tiny portion of my home being powered off the grid, even though I'll never see a difference in my electric bill. I don't know enough about batteries, so I worry about having one inside the house. I monitor its level constantly, never letting the battery get below 50%. I need to get a battery box, but with the gases that the battery gives off, I just don't know how much of a concern that is with the inverter being so close-by.

To resolve this perform a power cycle of the panel by first disconnecting AC power, then disconnecting the battery. From there wait 10 seconds then reconnect the battery first, then reconnect AC power.

Once thing you can try is to power down the panel completely, transformer first then internal battery, and wait two full minutes. While waiting you will want to remove the GC3 cell Sled and re seat it. Then power up the panel battery first then transformer and run a cell test, any change?

The LTEV1-A-GC3 would be the newest version of the Verizon LTE Sled, this would require the panel to be at Firmware version 3.1.3 or newer. As a reminder, equipment does not have to be purchased through us in order to be utilized.

If you are still seeing daily failures after troubleshooting it would be good to try switching carriers, yes. Based on coverage reports you would likely see improvement if the issue is coverage and not environment based.

I want to take to wireless router out of the closet and relocate to another room that is more centrally located. How would I do that using the ports in that room and what would be the wiring config at the switch and patch panel and wall port?

Connecting a modem to a patch panel is a process that requires some knowledge about the devices themselves and their basic functionalities. In this article, we will guide you through the steps involved in connecting a modem to a patch panel.

A modem is a device that is used to connect your computer or other devices to the internet. It is also called a network modem as it is used to connect to a network that provides internet access. It receives data signals from the internet service provider (ISP) and converts them into digital signals that can be understood by computers and other devices.

On the other hand, a patch panel is a device that is used to organize and connect network cables. It is a hardware component that helps in managing network connections. Patch panels are commonly used in data centers, server rooms, and in large businesses to help with network management and organization.
