-===== Getting started with a new Device Page ===== +
-  - This is an empty template that suggests the information that should be present on a well-constructed Device Page. This means, that **you have to fill it with life and information.** +
-  There are several "fixme" tags with text on a light background (like this text) throughout this template. As you fill in the pageremove those tags so that people can judge its completeness. +
-  - When there are no more "fixme" tags left, delete this one too, along with the ''<nowiki><WRAP></nowiki>'' that encloses it. +

-    - filters are not set correctly. Most common reason for "Nothing found": The dataentry does not contain a Version, but we are filtering here for version -> Please **edit this section and adjust the filters with the proper Brand, Model and Version.** In case the dataentry does not contain version, delete the line ''filter  : Versions~''.

 ==== OEM installation using the TFTP method ==== ==== OEM installation using the TFTP method ====
 +To consistently get the LBR20 into TFTP recovery mode, such as when you want to flash back to Netgear/Voxel from an active Openwrt image, pull power from the connector on the back, press and hold the RESET button with a SIM tool, and push the power connector back in. Wait 30 seconds before releasing the RESET button. The LBR20's white tower light should be regularly turning on and off, and the power LED indicator near the power port, should be blinking RED.

-==== LuCI Web Upgrade Process ====+===== Basic configuration ===== 
 +Use the LAN2 port as the wired connection to your laptop when flashing/configuring the ORBI LBR20, not the WAN/LAN1 port.
  
-  * Browse to ''<nowiki>http://192.168.1.1/cgi-bin/luci/mini/system/upgrade/</nowiki>'' LuCI Upgrade URL +Openwrt does not enable IPv6 on the cell connection by default. Only IPv4. That's a problem, because downloads.openwrt.org does not fully support IPv4, so you will get errors when trying to run 'opkg updatethen e.g'opkg install luci-ssl' (so you can have web access, as SNAPSHOT does not contain Luci)There are kludgy work-arounds for the underlying wget, but the best thing is to use an SCP app (such as WinSCP) to connect into the LBR20, and edit the file /etc/config/network, changing the 'pdptypevalue to be 'ipv4v6' instead of 'ipv4', and then save and restart the router. You should have basic cell connectivity now, particularly if the Orbi LBR20 was working previously on the Netgear/Voxel firmware, as the Quectel modem will pull configuration information from the SIM card. 
-  * Upload image file for sysupgrade to LuCI +  * The only text editor included with SNAPSHOT, is VI. Not nano or anything reasonably easier and intuitive. So you are in a Catch-22 if you want to ssh into the LBR20 and edit the network config. Unless you want to learn VI. That is why the suggestion to use SCP.
-  * Wait for reboot+
  
-==== Terminal Upgrade Process ====+===== Specific Configuration & Gotchas ===== 
 +Quectel modems in general have an earned reputation for having firmware stability issues and design flaws. If you run into frustrating issues specifically with regards to the cell connection/modem, it is not likely to be Openwrt. ''The modem runs its own closed-source firmware'', like a router within a router, and unless it's in QMI mode (''AT+QCFG="usbnet",0''), which is the default [where the IP assignment from the cell provider is directly assigned to the wwan interface] the modem also does its own routing inside the modem, which means you will get a double-NAT situation [if you use MBIM and NDIS instead]: 
  
-If you don't have a GUI (LuCIavailable, you can alternatively upgrade via the command line. +  * **DO NOT**, under any circumstances, tell the ORBI LBR20 tower LED lights (referred to as 'backlights' in the LED Configuration page in Luci) to blink in coordination with wwan0 (cell modemreceive/transmit. That causes some kind of hardware signal interferencewhich will cause a crash of your cellular connection/modem. If you notice, the Netgear and Voxel firmware do not use the tower light for that indicator, and in those, that light is completely off when the LBR20 is connected and running properly. A solid LED when the link status is ''ON'', such as a purple light by using both the red and blue LEDs, does not interfere.
-There are two command line methods for upgrading:+
  
-  * ''sysupgrade'' +  * NETGEAR provided only 2 firmware revisions for the LBR20 (NA models), that could only be flashed through the stock firmware; an A05, and A06 01.002. Both have issues causing disconnects, or the modem to become unresponsive, sometimes requiring a reboot. The latest (05/2024) firmware, A06 01.008, seems very stable [A12 for EG18-EA (EU) models], but is only available on the [[https://forums.quectel.com/|Quectel Support Forum]]. See also [[https://forums.quectel.com/t/latest-eg18napar01xxxm4g-firmware/39727/2|EG18NAPAR01xxxM4G Firmware Request]]; Quectel staff will email modem firmware to you on request - they do not at present have a download site. It can take a week for them to response. It may be faster to register to the forum and email another member who has already received it!
-  * ''mtd''+
  
-Note: It is important that you put the firmware image into the ramdisk (/tmpbefore you start flashing.+  * If you run the stock A05/A06, and do not have a wan watchdog script running in cron (Scheduled Tasksto try to compensate for the issues, the 4G LTE connection will just 'die', and you will have no internet.
  
-=== sysupgrade ===+  * **Qfirehose Quectel Modem Upgrade-Flashing Procedure**: Once you have acquired [[https://forums.quectel.com/t/firmware-for-eg18-ea/23995/56|the ''qfirehose'' binary]], put it in /root and mark it as executable. Unzip the Quectel-provided firmware to your computer, and upload the contents [//update// folder, //contents.xml//, and //md5.txt//] to the /tmp folder. There isn't enough user-storage space partitioned on the Orbi LBR20 to put it in /root. Disable your wan-watchdog.sh script. From a terminal (laptop) with a wired connection to the router, run 'qfirehose -f /tmp'. Allow the flash procedure to finish to 100% and confirm completion:<code> 
 +      * [083.292]: Upgrade module successfully.</code> 
 +      * The modem (not the entire router) will reboot 10 seconds later, and reconnect to the cell provider. 
 +      * Using ''picocom /dev/ttyUSB2'', send the modem an ''AT+QGMR'', to display the current firmware revision.\\ 
 +        * The latest A06 01.008 modem firmware, does not display a 01.008 revision code after the ...A06M4G response. 
 +        * The Netgear-provided A05 firmware, also does not display a revision code after the A05M4G response. 
 +        * The ''/dev/ttyUSB2'' may disappear after flashing, and be replaced with /dev/ttyUSB3 (0,1,2&3 -> 0,1,3&4). That is a temporary artifact of flashing the modem. You might try ''/dev/ttyUSB3'', or reboot the ORBI LBR20, and the assignments will revert to 0,1,2&3. 
 +==== QMI / wwan0 / 4G LTE Monitoring Script ==== 
 +Here is a wan_watchdog.sh script that tests the connection, and if it receives no response from several well-known DNS providers, it will: 
 +  - Tell the modem to soft-off. 
 +  - Wait 
 +  - Tell the modem to soft-on (boot up). 
 +  - Wait 
 +  - Restart the interface.
  
-  * Login as root via SSH on 192.168.1.1, then enter the following commands:+  * You will need to add the packages 'socat' and 'fping'
 +  * Save this as 'wan-watchdog.sh' in your /root/Make it executable (''chmod +x wan-watchdog.sh''
