Upgrading Toastman firmware on my Asus N-16

    I have configured the hell out of my N16 with portforwards, static IP's etc etc..

    My current version is:
    1.28.7501 MIPSR2Toastman-RT K26 USB VPN

    I want to upgrade to:
    tomato-K26USB-1.28.0503.6MIPSR2Toastman-RT-N-VLAN-VPN-NOCAT.trx
    (or if someone could suggest a better more recent stable firmware)

    Will the later firmware be compatible with my settings backup? or can I just use the firmware upgrade feature & retain all my settings??

    Thankyou

    It looks like you're going from RT to RT-N. Nothing wrong with that, just keep that in mind if you run into wireless driver issues (you shouldn't on the RT-N16). I recommend you not bother with the VLAN firmware unless you really do plan on using VLANs, by the way.

    With any firmware upgrade, if you want to play it safe, then follow the below method. Toastman also has a post somewhere explaining his methodology (which is more or less the same I think, just better-phrased).

    You should maintain a list (in a text file, etc.) of all the settings you change from stock defaults. When upgrading, first back-up your bandwidth usage data (if you use/care about that feature) ditto with Web Traffic or IP Traffic or whatever it's called. In the Upgrade menu, be sure to check the "After flashing, erase all data in NVRAM memory" box. After the router upgrades, it'll be back to stock defaults. You should then go back and manually adjust all the settings (manually) by following what's in the text file.

    The firmware maintainers try hard to retain compatibility of NVRAM variables/syntax when changing things, but that effort is not always guaranteed, so it's best for you to track what you change on your own. Attached is an example of the text file I maintain for my own router.

    You could have problems if backup is from RT and you are upgrading to RT-N, my backup wasn't recognised as from the same router!

    If we're talking of just upgrading from one to another:
    I've done this numerous times, usually, things just work, I've only experienced some hit'n miss with wireless network names, but a quick fix if something doesn't work is just go to the respective gui part and save the right settings... It usually fixes it.
    You can try just upgrading and see if everything works, but, the RECOMMENDED WAY is to reconfigure everything by hand, even if you're upgrading the same release!
    Don't come and say this or that doesn't work if you did't done a NVRAM erase, because usually that is the problem!
    Have the router conected trough Cat5 wire, as wireless networks usually have problems between versions...


    NVRAM variables rarely change (it's the same kernel)... and it should work, but be prepared to face problems or instability if you take the lazy way!

    My bullet proof method is: Save everything with Offline Explorer, it retains all settings :) then configure everything by hand using the saved webpage as a template... it's so simple and fast, and all variables are perfect!
    Offline Explorer saves all pages from the router interface so you end up with a perfect copy!
