How to stop “reloading firewall due to ifup of modem”

This happens throughout the day and makes me lose connection to the internet which isn’t really usable as I need to be on zoom meetings throughout the day. There is no loss in connection to the tower. Please help or point me in the direction of help. I am willing to pay someone to figure out my setup as this is my only internet option besides satellite.

I’m using a GLiNet Spitz GLX750 Cellular modem for use as rural home internet. I’ve factory reset numerous times. It’s connected to a tplink archer a5 as an access point where all my devices connect. I’ve gotten one lead that says it’s an ISP problem which could be possible as I just buy an ATT “unlimited” plan from a random online reseller so it could be an issue with their method.

The firewall service reload should not cause connection reset.
Moreover, OpenWrt firewall depends on that reload to assign the zone properly.
Your issue is most likely due to the modem dropping connections by itself.
Unstable power, or too heavy load, or crappy firmware/hardware, etc.

Any suggestions on how to troubleshoot besides trying a new PoE injector and splitter? Could it also be an ISP issue? And how is it that the exact time internet is dropped this message appears? I’ve checked dozens of times immediately when it goes down and it seems to match up perfectly.

The ifup event means the interface was down.
If not you put it down, then only the modem by itself.

Isolate the problem by connecting the modem to the PC directly and test it for some time.
Try to simulate heavy load scenarios with something like torrents and/or streaming.

I appreciate your help in narrowing this down! I think I may have found the problem. I paid zero attention to the volts and Amps of the poe injector and splitter when I bought them. The modem says it’s power input is 12V/1.5A yet my injector is 48V/0.5A and my splitter is 12V/1A. Please lord almighty tell me that this could be the issue...

It could be. The injector will inject 24 watts but the "splitter" whatever that is will only supply 12 watts and the device needs 18.

Make sure you can supply the full 18 watts and see if it helps

The splitter removes that power from the ethernet into a barrel connector to power the modem (its in a tree with antennas). I just ordered new PoE adapters, but before I get my hopes up, could it be possible the ISP is causing the modem to go down?

sure it's definitely possible. It's even possible it's both. I imagine the modem modulates its power usage based on signal quality. So something the ISP does could make it try to up its power output and then fail to get enough power from the adapter.

I replaced the poe injector and splitter and can confidently say it’s getting enough power. Modem requires 12v 1.5 amp and the splitter can supply 12v 2 amp.
I’m still getting the firewall reload and internet going down at the same time.
Is ISP or hardware the more likely cause?

EDIT: Btw sometimes when it’s snowy it can only connect to 3G. When it does that this issue does not occur at all.

Hmmm sounds like radio/signal/access management, etc. Like maybe your modem is booted off the cell site when there is a lot of demand or poor signal. Maybe when you access with 3G the signal is more robust. Usually higher speeds = more easily interfered with

You must be exactly right. I switch from band 2 to 4 and haven’t had the issue for days.
