I was writing another page on installing OpenWRT and realized that the version I was using was no longer current. To make that page more relevant I thought I should document the steps to update the OpenWRT installation on a TP-LINK TL-WR703N.
- reboot the 703N
- telnet into your 703N as root
- Make sure the 703N can access the internet. My 703N is connected connected via it's Ethernet port (192.168.1.1) to my laptop (192.168.1.2) which is connected to the internet.
- Get the updated firmware
cd /tmp
wget http://downloads.openwrt.org/snapshots/trunk/ar71xx/openwrt-ar71xx-generic-tl-wr703n-v1-squashfs-sysupgrade.bin - Get the MD5 sums to verify the firmware file.
wget http://downloads.openwrt.org/snapshots/trunk/ar71xx/md5sums - Extract the one MD5 checksum we need:
grep openwrt-ar71xx-generic-tl-wr703n-v1-squashfs-sysupgrade.bin md5sums >| onefile.md5 - Verify the firmware file we downloaded
md5sum -c onefile.md5 - Look for: openwrt-ar71xx-generic-tl-wr703n-v1-squashfs-sysupgrade.bin: OK
- Run the upgrade command:
sysupgrade -v /tmp/openwrt-ar71xx-generic-tl-wr703n-v1-squashfs-sysupgrade.bin
