Verizon LTE sled upgrade GC3

I am seeing a lot of successful initialization commands, but near the end the commands started failing. Can you try running another cell test now and let me know what the result is?

ok, testing in progress

sticks on “waiting cs response” then it just goes to “cell module status not detected”

now it went back to the screen where it says test failed

Interestingly it at one point said I have signal strength of 2/6, and now seems to say signal strength is 1/6 (I have verizon cell service and get decent LTE reception in my home)

You may be experiencing a portion of the issue described here. I have noticed many more GC3 related LTE problems during this operations alert, and if this is affected it will require the carrier to fully resolve.

It looks like cell pings are still failing but your panel is communicating normally via wifi.

Yeah, it will intermittently accept commands from the mobile app i am assuming over wifi, but intermittently stops, so we basically don’t have control of the system except from the panel itself

one thing that did seem to help was connecting to my 2.4ghz network rather than the 5ghz (at least in regards to being able to have the system communicate via wifi only)

As of about 15 minutes ago all of the normal initialization commands were processed. The panel shouldn’t have a back log of incoming commands at this time. I would try testing commands again to the system as it should be sending concurrent cell and wifi, and wifi should be as reliable as the local network is.

Yes, you’ll want the panel on 2.4. It does not need the speed of 5Ghz and 5Ghz networks do not have the coverage that 2.4 does generally.

Ok, so what should I do about the cell module? I saw the other thread you referenced. Do you need to un-provision it (or whatever the terminology is) and restart the whole process? Let me know if you have some way to make the system work again.

No, the cellular issue in that thread should be resolved soon without further troubleshooting. The problem referenced there is on the carrier end. Alarm.com is working with Verizon and Verizon is making rolling updates to their network to resolve this from what I’ve been told. Some modules previously affected have had the issue resolved so far.

Click the bell icon on the operation alert thread and watch that thread for notification whenever new updates are posted.

The last troubleshooting step I would try, just in case this is not related, is an extended power down of 10-20 minutes.

Power off the system transformer first, then battery, then wait 20 minutes. Plug in battery, then the transformer. Wait a couple minutes and then try a cell test again.

However I have gotten quite a few GC3 LTE reports lately, which all appear to be affected by this operations alert unfortunately, so it is likely the cause here.

Hey, I still have not been able to resolve this issue. Can we revisit this? Hope to get it working soon.

Hmm, the issue I was referencing above should not be affecting it at this time.

Did you try the extended power down suggested?

Try an extended power-off for at least 10 minutes now. Any luck? Modules that were affected by this issue may need a power cycle to reconnect now that the carrier problem is resolved.

Hey yes I tried the power down

Please try another extended power-off for at least 10 minutes now. Any luck? Modules that were affected by this issue may need a power cycle to reconnect now that the carrier problem is resolved.

If this does not work, you may have a bad module.

It seems to recognize that there is a module, shows 1/6 signal strength, says “not registered”, and fails the radio test , then goes to cell radio module status not detected. I’ve tried re-seating the module.

Also, the battery seems to have failed during the course of this process. It no longer powers the gc3 unit when I cut power.

Hmm. If you pull on the wires to the battery connector one of the wires may have come loose. Double check where it fits on the connector.

Regarding the module, can you send a photo of that module’s IMEI to us as a private message? I want to double check the IMEI against what is in ADC.

I think the last step I would try in this case is open the cell sled and be sure that the internal antenna is secure, unplug and reconnect that antenna, then close it up, plug in the module, power up the panel, wait about 5 minutes, then try a test again.

Yeah I’ve checked the sled. Do you mean actually looking inside the sled itself? Like unscrewing it to make sure the antenna is connected? I don’t think that’s what you mean but wanted to double check. Is it possible the sled is defective? Has this been an issue? I see another thread where someone had a similar problem.

Yes, I do mean open the sled up. There is an antenna inside with a plug connector. That connection may be loose. ADC has suggested this as a possible cause.

That is likely the last troubleshooting, given all the other troubleshooting performed. If removing and reconnecting that antenna does not resolve the issue then I think replacement is the next step. Let me know if you have any success with the above.
