In older posts here<\/a>\u00a0and here<\/a> I described my experiences with setting up the official Buffalo DD-WRT build on the Buffalo WZR-HP-G300NH router. It’s been a while and I’ve been wanting to update the DD-WRT version to the latest available build for this router – 22118. Why? Because being a geek, I just can’t stop tinkering – that’s why.<\/p>\n

The upgrade itself went fine – I just downloaded the build from here<\/a> and upgraded using the web UI. Everything went seemingly fine and the router booted back up without issues. I did not do a full reset. Network connectivity (both LAN and WAN) was fine and wireless seemed to be working fine too. However, I noticed that the USB stick that I had provisioned for optware and other data wasn’t mounted properly. The web UI seemed to indicate that it was mounted as expected, but when I looked at the output of mount in a PuTTY console it clearly indicated that none of the partitions other than swap was mounted correctly. dmesg didn’t indicate any issues either – no errors. After scratching my head for a while, I first tried to mount the partitions in the USB stick manually. My first attempt didn’t specify the file system type and failed, but once I specified that the file system type as ext2, it mounted fine.<\/p>\n

Still at a loss for why automount wasn’t working, I went back to the web UI and carefully looked at the output and finally figured it out – this build has a bug where automount mounts ext2 partitions as ext4!! To add insult to injury, the mount fails silently.<\/p>\n

Now that I had figured out why things weren’t working as expected, now it was time to figure out how to fix it. After a bit of trial and error, this is how I fixed the problem – manually load required modules (mbcache and ext2), manually mount the partitions in my startup script. Note that you still want to leave the option for automount on – this loads a bunch of modules that are required for USB support. Here’s my modified startup script that seems to work:<\/p>\n

#!\/bin\/sh \r\n\r\ninsmod mbcache\r\ninsmod ext2\r\nsleep 2\r\nmount \/dev\/sda1 \/mnt -t ext2\r\nsleep 5 \r\nif [ -f \/mnt\/optware.enable ]; then \r\nmount -o bind \/mnt\/etc \/etc \r\nmount -o bind \/mnt\/root \/tmp\/root \r\nmount -o bind \/mnt\/opt \/opt\r\nfor f in \/opt\/etc\/init.d\/S*; do\r\n    [ -x $f ] && $f start\r\ndone \r\nelse \r\nexit \r\nfi<\/pre>\n
I haven’t tried the built-in privoxy in this build, but I suspect it will have the same high CPU usage and slow response issues I saw with the optware version when used with fanboy\/easylist block lists. My suggestion for anyone thinking of upgrading to this build would be to wait if you can – I’ll post an update after 1 or 2 weeks of use about WiFi stability and any issues.<\/p>\n
Update 1\/31\/2014 – I’ve had the router running this version of the firmware stably for roughly 3 months. Haven’t seen any issues with WiFi connectivity or speed. Looks like it is safe to use this version once you work around the automount bugs.<\/p>\n
Update 2\/19\/2014 – Fixed link to the version of dd-wrt I’m running on this router.<\/p>\n","protected":false},"excerpt":{"rendered":"
