Installation
OpenWrt should be installed with TFTP.
OEM installation using the TFTP method
Upload the openwrt-wrt610n_v1-squashfs.bin image with TFTP.
Upgrading OpenWrt
If you have already installed OpenWrt and like to reflash for e.g. upgrading to a new OpenWrt version you can upgrade using the mtd command line tool. It is important that you put the firmware image into the ramdisk (/tmp) before you start flashing.
LuCI Web Upgrade Process
- Browse to http://192.168.1.1/cgi-bin/luci/mini/system/upgrade/ LuCI Upgrade URL
- Upload TRX file to LuCI
- Wait for reboot
Terminal Upgrade Process
- Login as root via SSH on 192.168.1.1
- Use the following commands to upgrade.
cd /tmp/ wget http://downloads.openwrt.org/latest/brcm-2.4/openwrt-brcm-2.4-squashfs.trx sysupgrade /tmp/openwrt-brcm-2.4-squashfs.trx
- If sysupgrade does not support this router, use the following commands.
cd /tmp/ wget http://downloads.openwrt.org/latest/brcm-2.4/openwrt-brcm-2.4-squashfs.trx mtd write /tmp/openwrt-brcm-2.4-squashfs.trx linux && reboot

Failsafe mode
If you forgot your password, broken one of the startup scripts, firewalled yourself or corrupted the JFFS2 partition, you can get back in by using OpenWrt's failsafe mode.
Boot into failsafe mode
- Unplug the router's power cord.
- Connect the router's LAN1 port directly to your PC.
- Configure your PC with a static IP address between 192.168.1.2 and 192.168.1.254. E. g. 192.168.1.2 (gateway and DNS is not required).
- Plug the power on and wait for the DMZ LED to light up.
- While the DMZ LED is on immediately press any button (Reset and Secure Easy Setup will work) a few times .
- If done right the DMZ LED will quickly flash 3 times every second.
- You should be able to telnet to the router at 192.168.1.1 now (no username and password)
