Transfer back-up configuration from one WRT54GL to another

    Recently, I flashed one of my WRT54GL routers with stock Tomato firmware, then upgraded to Victek's mod (For the bandwidth limiting feature, since stock Tomato's QoS wasn't exactly what I needed). I changed the settings, and saved a back-up configuration with the intention of cloning those settings onto my other WRT54GL router. I flashed this second router with Tomato, upgraded to Victek's mod (and of course cleared the NVRAM), and then attempted to "restore" the back-up configuration, but received the error: "Cannot restore on a different router".

    Is there some other way I'm supposed to transfer the settings I've made on router to another?

    Note: I'm running Tomato Firmware RAF 1.28.121006 on both WRT54GL routers.
    On another note, I find that I am unable to input a range of IP addresses in the bandwidth limiter (e.g. (the total range of wireless IP addresses that I have allowed) gives me the error "Invalid IP", and the limiter doesn't function) Once I go back to specifying individual IP addresses, the limiter works like a charm. I don't want to have to list all of the possible IP addresses, and then to have to change the upload and download limits individually! I received a kind message from benny.shen with a firewall script, but couldn't get that working.

    Sorry to say but your safest bet is to manually re-key all the info. I know its a PITA but you will save yourself some potential stability issues in the long run.

    Thank you both for your input :) I'll go read those forum posts right now!!!

    Been there done that...yes you can make it work. Upgraded my WRT54GL to an e3000 and was able to import the settings. Would work for a week or two then ended with the router locking up with all the lights flashing. Couldn't even reboot it and restart, had to hard reset and reinstall the firmware.

    After the third time of reinstalling the firmware and doing full nvram erase i thought i was having a hardware problem. I manually re-entered all the settings and have not had any problems now for over 3 months. Maybe if you upgrade using the identical firmware versions between devices you might get lucky.

    Using the configuration backup and restore in the GUI is, IMHO, pretty much only to back and restore a single router.

    I did use Toastmans method linked to above to transfer quite a few settings recently to a new primary router. This would have been painful to manually re-enter such as static IP info and it worked like a charm.

    You have to be very careful about what you move over. Anything hardware, or firmware if you're switching builds, specific will cause trouble.

    Way back in the day before I knew better, I tried to write a script to dump and restore NVRAM in that same fashion and killed a router by restoring a dump of it's own NVRAM, that's how picky some hardware NVRAM settings are and how bad the trouble can be. If you follow Toastmans guidance and are selective it works fine and can save a lot of effort.

    Nice script shibby20. So the backups get stored in /tmp and restores require a commit to, uh, be committed, :tongue:.

    I've been using Tomato for a few months now, on several routers, but just ran into this restore-to-a-different-router issue a few weeks ago. This is a huge problem for me -- in some locations, I can't just plug in a new router, change 3 settings and be up and running. In addition to the usual settings, I'd still need to set up static IP's, up & down min & max speeds, and priorities for, potentially, up to 20 or so different users, and that's without even using the real complicated QoS settings. I simply cannot imagine why on earth someone could think it's a good idea to not let me restore a configuration to a different router. But I digress...

    So, I have 2 questions:

    1. Who would one ask about getting this changed, either in all of Tomato, or maybe getting a Tomato mod made without this problem? (I'd do it myself if I had the programming skills.)

    2. Can anyone point me to a firmware without this problem? Either a Tomato mod, or some other firmware? (DD-WRT won't work, as its ACK timing is broken for Broadcom devices, so I can't use it for links of more than roughly a mile or so, because of low throughput.)

    I really like a number of things about Tomato, but I may have to switch away from it on some routers because of this problem.
