RT-N12 = RT-N or RT Toastman? Random Wireless Dropouts

    Hey Toastman and Community-

    I noticed that Toastman has the Asus RT-N12 listed under the RT-N releases, NOT under the RT releases. Is this only for the newer RT-N12’s with the higher db antennas or do the older N12’s without higher gain antennas also fall under RT-N category too?

    The reason I ask is because every day my wireless drops out randomly for about 30 minutes and then comes back. There is no rhythm or rhyme as to when/why this happens, just totally random. When it does drop out, the wired section of the router is still fully functional. Just the wireless SSID disappears and you can’t connect to the router. If you change from channel 11 to channel 6 or vice versa, it sometimes will come back immediately, sometimes not.

    I always thought that this happened because there is a lot of wireless congestion in the area, but maybe it’s because I have been using the RT releases and not the RT-N releases.

    Can anyone comment on this?

    There are two versions of the RT-N12 - the original V1 with regular antennas use


    Broadcom BCM4716 @ 300 32MB RAM
    4MB Flash

    - this uses the RT release

    while the newer RT-N12 B1 - with higher gain antennas use


    Broadcom BCM5357 @ 300 32MB-RAM 8MB-Flash
    - this uses the RT-N builds

    that's what i thought, but he doesn't have the RT-N12 listed under the RT builds at all, just under the RT-N. if what you say is true, people are loading the wrong firmware on lots of N12's out there.

    also, what could cause the wireless to just completely drop off daily. SSID just disappears...

    RT-N12 = Prefer RT builds but RT-N will work.
    RT-N12B = RT-N only with this unit.

    ok that's exactly what i thought.

    regarding the random daily outages with the wireless, would it be recommended to try the RT-N builds to see if that clears it up? guess i don't really have anything to lose by doing so??

    it seems like i had a lot less wireless drops using the old build 54 tomatousb which has the 5.10.56.46 wireless driver. i see toastman's RT releases use 5.10.147 which i have a lot of wireless drops. i will try the RT-N which uses 5.100.138.9 and see what happens good or bad!

    The only problem with the RT-N builds is that the 5.100.138.9 driver is large and makes the firmware heavy. The RT-N12 has only 4MB of flash so you are really restricted on what version you can use. I have three RT-N12 in operation with no problems. I use toastman's tomato-K26-1.28.7494.3MIPSR2-Toastman-RT-Std with no problems. It uses the 5.10.147.0 driver. Funny thing is when I first set up the RT-N12 I had to use the mini version first and then the upgrade to the standard version otherwise it would not load. If you have tried nvarm erase with no luck you might have bad hardware.

    i will use the mini version and give the 5.100.138.9 a shot. i have tried several different N12's, all with the same results. SSID just randomly disappears still :\

    If the dropouts occur with more than one RT-N12 than something else must be at play. Do you have something in the area that generates RF like a microwave oven, a big CRT monitor, or a cordless phone? I would also use inSSIDer to scan your area to see if there are any interfering routers nearby.

    there are lots of other networks in the area, i have tried 1, 6, 11 and other channels in between. 1 doesn't work at all, where-as 6 and 11 work "most" the time. there are not any microwaves or crt's around the router at my house. i don't own a cordless phone, only a couple cell phones in the house.
