-The Netgear R6220 is a simultaneous dual band WIFI router with AC1200 WiFi - 300+867 Mbps (2.4 & 5 GHz) speeds. It contains non-removable external antennas. The router features 4 Gbit LAN and one Gbit WAN port. It comes with a large 128 MB NAND ROM with space for many packages and a single core (dual thread) MIPS CPU powered by 128 MB RAM.+The Netgear R6220 is a simultaneous dual band WIFI router with AC1200 WiFi - 300+867 Mbps (2.4 & 5 GHz) speeds. External antennas are non-removable.

 The R6230 is most likely internally identical to the R6220. OpenWrt installation has been achieved by treating the device as an R6220. Although success has been achieved on two units, the R6230 is not officially supported. The R6230 is most likely internally identical to the R6220.

-Simply apply a ''factory'' OpenWrt image via OEM web-gui. +For security reasonit is recommanded to install the latest stable version, but you can also install snapshot in the same way
- +In Netgear OEM GUIgo to  ADVANCED > Administration > Firmware Update
-After installation on 19.07you'll noticed : +Select the ''factory'' OpenWrt image you have previously downloadedthan click on Upload. You will have a warning message, don't mindAt reboot, proceed to setupYou may have to refresh your browser cache.
-  * The wireless networks are disabled (normal default behavior of OpenWrt) nevertheless the wireless LED is still on. A reboot, or use of the wireless handswitch, restores the right LED status. +
-  * There is no default LED rules configurated, add some if you wish. +
-These tiny bugs ares fixed in 21.02. It is recommanded to run the latest version (23.03.4) anyway. +
-==== Installation through telnet (OpenWrt 18.06)==== +
- +
-**This is only for vintage technical purposeuse newer version of OpenWrt for obvious security reasons.** +
- +
-**Note**: OEM firmware 1.0.xxx will not work (mtd will not unlock for write). Version 1.1.0.50_1.0.1 will not work anywaybut versions 1.1.0.62_1.0.1, 1.1.0.80_1.0.1 and 1.1.0.86_1.0.1 are confirmed working. +
- +
-  - Copy kernel.bin and rootfs.bin to a USB flash disk, plug to usb port on the router +
-  - Call the link: ''%%http://192.168.1.1/setup.cgi?todo=debug%%'' (login if requireddefault: admin - password); if the above IP address does not work, try with 10.0.0.1. +
-  - You will see "Debug Enabled!" +
-  - telnet IP-address and login with "root" (default: admin - password) +
-  - ''ls /mnt/shares/'' to find out path of your USB disk - ''myUdisk'' for example +
-  - ''cd /mnt/shares/myUdisk'' +
-  - ''cat /proc/mtd > r6220.mtd.layout'' +
-  - ''cat /dev/mtd10ro > r6220.mtd10ro.factory.bin'' +
-  - ''mtd_write write rootfs.bin Rootfs'' +
-  - ''mtd_write write kernel.bin Kernel'' +
-  - ''reboot'' +
- +
-// Replace ''rootfs.bin'' and ''kernel.bin'' with the names of the images downloaded //+
  
 +If you choose to install 19.07 (not recommanded for security reason), you'll noticed these tiny bugs:
 +  * the wireless LED is still on while wireless networks are disabled (default behavior of OpenWrt). A reboot, or use of the wireless handswitch, restores the right LED status.
 +  * There is no default LED rules configurated.

-<WRAP BOX>+Upgrading can be done using LuCI or sysupgrade (in SSH) in the usual way. 
 +Upgrading from 19.07 to an higher version requires a complete new setup due to DSA syntax. So don't keep settings and reconfigure from scratch. Upgrading from 21.02 to a higher version can be done while keeping settings. Refer to the release note of each version for general purpose compatibility.
  
-FIXME These are generic instructions. Update with your router's specifics. 
  
-==== LuCI Web Upgrade Process ==== 
  
-  * Browse to ''%http://192.168.1.1/cgi-bin/luci/mini/system/upgrade/%'' LuCI Upgrade URL 
-  * Upload image file for sysupgrade to LuCI 
-  * Wait for reboot 
  
-==== Terminal Upgrade Process ====+===== Debricking / back to stock firmware ===== 
 +-> [[docs:guide-user:troubleshooting:generic.debrick]]
  
-If you don't have GUI (LuCI) availableyou can alternatively upgrade via the command line. +Debricking of the R6220 can be done by using the **nmrpflash** program. It is somehow ''tftp'' method to upload fileand so the stock firmwareSee details over here[[https://github.com/jclehner/nmrpflash]]. You will also need [[https://npcap.com/dist/|npcap]] tool. Versions 1.60 and 1.79 are working.
-There are two command line methods for upgrading:+
  
-  * ''sysupgrade'' +While the doc states to launch the progran THAN power on the router, it has been found that you must power on the router THAN launch the program for the R6220. After uploading the file, the message ''Received keep-alive request'' may take a while to complete (up to 4 min), so be patientIn the example below, notice **253s**. Reboot when told to by using the power button.
-  * ''mtd'' +
- +
-<WRAP center round important 60%> +
-It is important that you put the firmware image into the ramdisk (/tmpbefore you start flashing. +

-Debricking of the R6220 can be done by using the tool nmrpflash. See details over here: https://github.com/jclehner/nmrpflash +
-This tool can flash the stock firmwareyou can later install again OpenWrt. While the doc states to launch the progran THAN power on the router, it has been found that you must power on the router THAN launch the program for the R6220. The last message is to reboot the device. It may take a while since this message appears (>4 min), so be patient.+
