 +Known problems:
 +
 +  * WLAN0 defaults to 5G after a fresh installation, to enable 2.4G network, you need to config it manually in LUCI.
 +  * If you see jffs2 related warnings/errors after updating from the stock web interface, you need to do a reset in LUCI. The error will be gone after a cold reboot.

-<WRAP BOX> +Both LuCI web upgrade and terminal upgrade works.
- +
-FIXME These are generic instructions. Update with your router's specifics. +
- +
-==== LuCI Web Upgrade Process ==== +
- +
-  * Browse to ''<nowiki>http://192.168.1.1/cgi-bin/luci/mini/system/upgrade/</nowiki>'' 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: +
- +
-  * ''sysupgrade'' +
-  * ''mtd'' +
- +
-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: +
- +
-<code> +
-cd /tmp +
-wget http://downloads.openwrt.org/snapshots/trunk/XXX/xxx.abc +
-sysupgrade /tmp/xxx.abc +
-</code> +
- +
-=== 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: +
- +
-<code> +
-cd /tmp +
-wget http://downloads.openwrt.org/snapshots/trunk/XXX/xxx.abc +
-mtd write /tmp/xxx.abc linux && reboot +

 +There is an unpopulated USB 2.0 port on the PCB. To use it, you need to short circuit R31, LB15, R35, R38, and R37 on the PCB: 
 + 
 +{{media:dlink:dir-853_a1:usb_mod.jpg}}

 +  - D- 
 +  - D+ 
 +  - GND

 +This port should work on the official OpenWrt firmware, as ''mt7621.dtsi'' suggests that it is enabled by default.
