On my Buffalo WZR-HP-AG300H I thought it was time to upgrade from Attitude Adjustment to Barrier Breaker. (See below for upgrading to 14.07-rc3).
So I downloaded image openwrt-ar71xx-generic-wzr-hp-ag300h-squashfs-sysupgrade.bin and uploaded that to the router using the LuCI web interface on the router (System -> Backup/Flash Firmware -> Flash new firmware image).
Well the router rebooted. But there was a problem. No web server. No LuCI web configuration application. The latest OpenWRT firmware wiki page states that:
Prebuilt trunk images do not come with any web interface or GUI. You will need to be comfortable using a command line and remote shell to install one yourself: LuCI Essentials
Fortunately the Ethernet networking was still functioning. So I had to install LuCI. But it wasn’t so simple.

BARRIER BREAKER (14.07-rc2, r41815)
* 1/2 oz Galliano Pour all ingredients into
* 4 oz cold Coffee an irish coffee mug filled
* 1 1/2 oz Dark Rum with crushed ice. Stir.
* 2 tsp. Creme de Cacao
root@myrouter:~# opkg update
Updated list of available packages in /var/opkg-lists/barrier_breaker.
root@myrouter:~# opkg install luci-ssl # should but doesn't get all we need
root@myrouter:~# opkg install luci-base
root@myrouter:~# opkg install luci-i18n-english
root@myrouter:~# opkg install luci-lib-httpclient # needed for CGI to work
root@myrouter:~# opkg install luci-lib-proto-ppp # needed for PPPoE to my ISP in LuCI
root@myrouter:~# opkg install luci-app-firewall # needed for port forwards in LuCI
root@myrouter:~# /etc/init.d/uhttpd enable # needed to auto-start webserver on boot
root@myrouter:~# reboot # restart router to take new packages
Now if I haven’t skipped any steps you should be able to use your web browser to configure the router.
If you want to know what packages are available from the command line type:
opkg update; opkg list
If you want to know what packages are installed on the router type:
It seems that, at the moment, Barrier Breaker comes with a limited set of packages on default install.
Ethernet Switch Disabled by Default
Ticket #11143 documents a very real problem when upgrading to Barrier Breaker. The 4-port Gigabit Ethernet switch on the back of the router will pass traffic between router and ports, but not between ports.
The fix is to edit your /etc/config/network file and ensure the switch and switch_vlan sections are as follows:
option name 'switch0'
option enable_vlan '1'
option reset '1'
option vlan '3'
option device 'switch0'
option ports '0 1 2 3 4'
You can set vlan to any number from 1 to 15 (not zero). If you specify the ports string wrong the switch will silently fail (I was mistakenly trying to set it to 0 1 2 3 4 5 but that was one too many digits and the switch simply didn’t configure.
What this does: is turn on VLAN functionality in the switch. However we specify each port to be untagged (i.e. normal) and all the ports share the same VLAN (in this case I chose number 3 but any number except zero would do).
You can confirm that the switch is named switch0 by ssh’ing into the router and typing:
root@myrouter:~# swconfig list
Found: switch0 - ag71xx-mdio.0
Warning: if you can only access your router via wired Ethernet (and not radio) then you may disable access to your router – and have to TFTP flash it all over from scratch. So back up your configuration first!
When you are confident enter the command /etc/init.d/network restart – disconnect from the router and re-connect (or just reboot the router).
The LuCI GUI has a helpful page on the switch that lets you see which switch ports have been connected to (and what link speeds):

Upgrading to Release Candidate 3
2014-08-17: I upgraded my router to rc3 by downloading the firmware image openwrt-ar71xx-generic-wzr-hp-ag300h-squashfs-sysupgrade.bin.
I had to install LuCI again:

First observation: the LuCI GUI has a completely different style. Not sure if I like it, yet; the layout is less compact than previously.
