NETGEAR R6900 v2
The Netgear R6900v2 is an AC1900 simultaneous dual band N/AC (2.4 & 5 GHz) WiFi router with three removable external antennas. It features four Gbit LAN ports, one Gbit WAN port, dual core (quad thread) MIPS CPU, 128 MB NAND flash ROM, 256 MB RAM, and USB 3.0 port.
It is based on the MT7621AT and MT7615E chips and has several clones of the same FCC ID PY316200344: Nighthawk AC2100 and AC2400, R6700v2, R6800, and R7450
Support for this device and the R7450 were added in 22.03.00 when the AC2400, R6700 v2, and R6800 were already supported. Differences in clones include no USB 2.0 port and a Guest WiFi LED replacing the USB 2.0 LED.
Prior to 22.03, R6800 firmware installed and worked fine. NOTE: R6800 is pictured but identical.

Upgrading OpenWrt
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
If you don't have a GUI (LuCI) available, you can alternatively upgrade via the command line. There are two command line methods for upgrading:
sysupgrademtd
Note: It is important that you put the firmware image into the ramdisk (/tmp) before you start flashing.
sysupgrade
- Login as root via SSH on 192.168.1.1, then enter the following commands:
cd /tmp wget http://downloads.openwrt.org/snapshots/trunk/XXX/xxx.abc sysupgrade /tmp/xxx.abc
mtd
If sysupgrade does not support this router, use mtd.
- Login as root via SSH on 192.168.1.1, then enter the following commands:
cd /tmp wget http://downloads.openwrt.org/snapshots/trunk/XXX/xxx.abc mtd write /tmp/xxx.abc linux && reboot
