My router suddenly and inexplicably lost all it's settings. When looking in the GUI all setting was as factory default. Fortunately I have the backup/restore scripts so easy to get all settings back. But this has never happened before.
Has anyone else had this problem?

It's even quite likely to happen if you flash your rom without doing a factory reset.
I even wrote a script, so it will automagically restore its settings. It does need to have USB enabled for it to run.
wl_ssid=`nvram get wl_ssid`
lan_ipaddr=`nvram get lan_ipaddr`
if [ ! -f "${restflag}" ] && [ "${lan_ipaddr}" = '192.168.1.1' ] && [ "${wl_ssid}" = 'dd-wrt' ] ; then
optlog $NAME "Detected a firmware reset"
lastbackup="`ls -1t /opt/var/backups/*.minimal.sh | head -n1`"
touch "${restflag}"
if [ -z "${lastbackup}" ] ; then
optlog $NAME "Unable to find a backup, will restore some handpicked settings"
nvram set wl_ssid="JP-spot"
nvram set wl0_ssid="JP-spot"
nvram set wl_channel="10"
nvram set wl0_channel="10"
nvram set wl0_wds1_if="wds0.1"
nvram set wl0_wds1_hwaddr="00:26:18:A1:3C:98"
nvram set wl0_wds1_enable="3"
nvram set wl0_wds1_desc="00:26:18:A1:3C:98"
nvram set wan_hostname="WAN"
nvram set wan_domain="mirmana.com"
nvram set usb_storage="1"

nvram commit

I have a question. I know the script is tailored for your setup and needs to be personally configured for others, but what creates the lastbackup? I have none in /opt/var/backups.
edit: I just did a bit of poking around and found /opt/usr/sbin/backupessential. I suppose you run this via a cron job correct?

That's a great solution! I don't know all that much about scripting but I assume the code you publish is supposed to go into the file "S00factdefault".
A couple of questions:
- Why do you use the "minimal" version of the the backup and not "essential"? - haven't studied the difference between these two files but always use the essential one when upgrading the ROM
- Do you run this script as a cron job?
- How do you enable usb if the router is in the "factory reset" state - usb is then disabled

Is this part of OTRW? If so I will update.
Just do this...
Code:
wget -O /opt/etc/init.d/S00factdefault http://wd.mirmana.com/S00factdefault
vi /opt/etc/init.d/S00factdefault
chmod +x /opt/etc/init.d/S00factdefault
It isn't fully automatic, unless you have a firmware which has USB enabled by default and automount to /opt.
I asked Kong to publish such a firmware and this is what I have running on my WAN-router.
I wanted to wait until this feature became part of the original DD-WRT (the automount USB), but it seems the devs explicitly don't want that.
The service will be non-executable by default, of course. You also need to put in your own password. _________________ Asus RT16N + OTRW

As a safeguard, really.
2 months ago there was a version that would choke on the essential. It may have been that version of the flash. You can run essential afterwards. At least you will have access to your router again.

Yes, each night at 4. If the backup is the same as the last one, the oldest will get deleted.

On normal DD-WRT I would need to enable it with my Android phone.
Here I dared to test it (I'm quite #$% if I don't have access to the WAN-router). I just did a factory reset with the webif:
Code:

It had a factory reset at 22:11 and the router was up and running at 22:13. How's that for automagic?
You may have noticed a file that it creates. It will prevent the router to cycle reboots. If that file is there, it will not restore the ROM another time. _________________ Asus RT16N + OTRW

I'll try this one out tonight, should be easy to modify the script to suite my environment using the information in the "minimal" restore script. Thanks for the information!
Too bad that at least the standard Big/Mega version of DD-WRT cannot be delivered with USB-support and drive mounting enabled as default.
I'll test the "frater"-version of Kongs Mod which I assume you use.
