    I am planning on buying a an Asus RT-N12 router for my old uncle who will only use it for streaming movies and browsing on internet.

    I want to install tomato on it. I understand that this one has only 4mb of flash on it.
    1. Any suggestion on which build to install?
    2. Is this MIPSR1 or MIPSR2?

    Any suggestion would help.

    My RT-N12 B1 reports 8 MB of flash, not 4MB.

    It's been extremely stable with Tomato Firmware v1.28.0500.2 MIPSR2Toastman-RT-N K26 Std.
    Attempting to flash with a RT build resulted in failure. Apparently it needs RT-N.
    In light of today's updates, you may want to try 0500.3. I'll be doing the same.

    This is stated quite clearly in the description of the RT and RT-N directories on Toastman:

    • RT (MIPSR2 - newer routers like RT-N16, E3000,WNR3500Lv1 etc) - NORMAL BRANCH
    • RT-N (MIPSR2 - E4200, RT-N10U, RT-N12B1, RT-N66U, WNR3500Lv2, RT-N15U (NEW MODELS)
    Note that the RT-N12E (note the "E" on the end!) is also different and isn't supported.

    Supposedly the original Asus RT-N12 (i.e. "hardware rev 1") has to run RT (not RT-N), according to Shibby's list:


    Also check out this guys' page, where he itemises all the different Asus RT-Nxxxx models and how keeping track of this nonsense is basically a serious pain in the ass:

    RT-N12 has 4 mb of flash. The B1 has 8 mb.
    I looked everywhere to figure out which build I needed before I posted here because I could not figure out.
    Is this MIPSR1 or MIPSR2?

    Did you not look at Shibby's list? It's listed quite clearly there.

    For the RT-N12, the router is MIPSR2, and you should use the RT (not RT-N) firmware with it.

    I see it in Shibby's list. I was not sure if it was MIPRS 1 or 2.

    CPU R2 means MIPS R2.

    Yeah, RT-N12 is MIPSR2 and RT, while RT-N12B1 is MIPSR2 and RT-N.

    I believe so long as the CPU type is correct the router will boot and be reachable over ethernet, the wireless interface just won't go up. Or maybe I just got really lucky the couple times I've put the wrong RT/RT-N version on my N12s/N12B1s.
