No Dual Band on ASUS N66U?

    I feel like I'm missing a tiny, stupid setting, but I've only got the one wireless band (2.4ghz) on my newly installed TomatoUSB Shibby 112 on an ASUS RT-N66U.

    The build I installed was tomato-k26USB-1.28.RT-N5x-MIPSR2-112-Mega-VPN-64K. Anyone have any ideas?

    No clue.. erase nvram and reboot again.

    I just reflashed to the AIO build for the same model AND cleared the NVRAM for the fourth time, and still I have no 5ghz wireless band. Did I get a defective router or what?

    How are you checking for the second band? Is the problem that you cannot see the 5 GHz SSID with your client devices (in which case, make sure they actually support 5 GHz) or are you missing the options to configure it on the router's webui?

    I'm missing the options to configure it in the WebUI, and I've got no light for 5Ghz on the front of the router.

    So yesterday I tried flashing some Toastman builds, and all 3 of them wouldn't boot after flashing, they all got stuck in a boot cycle. Shibby's build works fine but like I said, pretty much the reason I bought this router was for 5Ghz. Should I just bite the bullet and go back to stock firmware?

    When I flashed Shibby's 112 for the AC66U to my router, I had to reboot Tomato before the 5GHz configuration section would show up in the GUI.

    What were the 3 that you tried?

    I would try erasing nvram after flashing (if you haven't done so yet), then rebooting to see if you get the missing options back. Also make sure it's not your browser caching older webui pages - try either clearing the browser cache or a different browser.

    Toastman: I tried the ext and the vpn of the nvram64k k26usb, and then i was reading about how it may not work, so I also tried the k26usb standard vpn build. All of them seem to reboot every 15 seconds or so, after the flash.

    I've tried another browser, and I've tried rebooting Tomato multiple times, with NVRAM clears. I think today I might give the standard ASUS firmware a shot to see if it shows up there. If not, I'll probably need to RMA it.

    What hardware revision do you have in your device B1 or B2?... give a try to TomatoRAF, version here is the link http://victek.is-a-geek.com/9013.html , use the Asus recovery tool.

    I've got a B1. Sure, I'll give that version a shot and see if I get the 5Ghz range.

    RAF build, still no 5Ghz. Trying the stock firmware.

    Just got the original firmware running. I have options for the 5Ghz SSID, but the light on the unit is not lit, and none of my 5Ghz capable devices can see that SSID. I'm starting to think it's a defective router.

    Those won't work on a 66U ... stick with Shibby, and I think Victek may also have it included in his release.

    EDIT - I just saw Vic's reply, he has it too.

    Question: Do you see MAC address in 5GHz band ?

    Nope, it's blank on any page that references it.

    Ok, one solution .. ask somebody of kind guys to paste in the forum the nvram dump text file for a default configuration, then, compare your router nvram dump text with the one pasted and add the values (hopefully I think all values related to wl2 are not in your nvram dump text), enter in command window and add these values with nvram set ..... in front of each value and the problem will be solved.
    My thoughts... you tried a 32KB dd-wrt version before and these values was erased... then you need to enter it by hand, it's the only way.. but your router will run again 5GHz.
    For wl2 MAC enter wl1 value + 1.

    sickfallout, did you ever get this to work? I have the EXACT same issue was you, from what i can tell.

    I got my N66U router today, installed tomato, and I do not have the 5GHz light. I don't see the 5GHZ configuration at all, all I see is 2.4GHz. I put multiple versions of tomato, still can't get the 5GHz light to come on or recognize it.

    I then installed merlin's latest firmware. It shows configuration for the 5GHz, but the light is not on, and my wireless clients can not see it (they are connected to an e3000 5GHz, so they do support it)

    sickfallout, I see you haven't posted in over 2 months...you didn't happen to return it to Amazon, did you?

    Have you tried installing Tomato and then rebooting the router? I had to do that on my AC66U to get the 5GHz config to show up; it seems to be a pretty common issue.
