EG18NAPAR01A06M4G Reset

It’s no longer registering with the provider. I have read your entire 317-page manual, and it’s not of much use.

AT+CREG?
+CREG: 0,3

This is the second quectel device we’ve had die for no particular reason.

There must be a way to actually reset these devices. It would be stupid not to have it/share it, but I don’t see it anywhere in your manual. I’m going to try this EG18NAPAR01A06M4G_01.005.01.005 flash, as one of your Support persons seemed to indicate it resets certain values in the modem, and there is no other way provided by Quectel to reset their devices. :frowning:

Set the modem to QMI mode and it’s working again.

Aannnnd. It just quit again.

This Quectel stuff is not reliable. At all!

I think I found the issue.

I remember a thread, where someone said, they had turned on a connectivity indicator LED, in the Quectel AT commands. And that this inextricably, in their mind, had caused connection problems. And the issue went away when they turned it off. And the Quectel staff advised them to turn it off, due to some design issue in the chip/board, even though the feature was technically available.

I installed the Voxel firmware for the Orbi LBR20, over the Openwrt SNAPSHOT it had been running (power off, press and hold RESET, push in the power connector, wait ~30 seconds, tftp in the Voxel image), and deliberately downgraded the EG18-NA firmware to A05. Then the Voxel had no issue connecting. And it stayed connected over 24 hrs. No interruptions. [There is clear line-of-sight to the cell tower, so there should be no connectivity issues, and there are no issues with any of the other devices on the same tower.]

After proving that the hardware fundamentally works, I flashed Openwrt and loaded my settings. The wwan0 (quectel EG18-NA) crashed again, within a few minutes. Realizing that the Voxel firmware did not have an activity indicator tied to the light ring on the top of the Orbi LBR20 - it had been off the whole time running Voxel, except on startup, which is the default behaviour - I had configured Openwrt to trigger red on transmit/link on, and blue on receive/link on, making a nice pretty flashing purple color - I deleted the two LED instructions.

It’s now been steady for 30+ minutes. That is a long time - previously, the wwan0 connection would crash in some way, every few minutes.
