Odd problem on 5GHz & 40MHz, RT-N66U w/ shibby RT-N 112-AIO

    I just installed a new RT-N66U and flashed to shibby's 112-AIO build (not Newdriver one) and am having trouble with 5GHz using 40MHz width. 2.4GHz and 5GHz w/ 20MHz seem OK.

    When I try 5GHz and 40MHz I can connect to the router, but after a minute or two the connection goes dead. I can not browse the 'Net and can not even get back into the router's setup. When I look at Win7's Network and Sharing Center I see the connection to Internet is broken for a while, then is OK for a while. It keeps alternating, but I can not reach the Internet or router.

    I do have an Intel 6230 card and read a little bit about a problem mentioned here but am unclear what exactly it is. Is it the problem I am having or something else?

    Any other help?

    Thanks! :)

    Just re-installed my Intel driver and still having problems and still confused.

    Was the reported problem with Intel cards and 5GHz & 40MHz width happening on the RT, the RT-N, or the RT-N NEWDRIVER builds? I can't seem to find the info anymore...

    Thanks for any help! :)

    Tomato Firmware 1.28.0000 MIPSR1-114 K26 USB AIO
    main router, RT-N56U (ralink chipset).
    Tomato router (ZTE ZXV10 H618B), set up as wireless ethernet bridge, wont connect to main router. I tried "auto & G only".

    Note: For the moment, I remedy this using wired ethernet. Iphone3Gs and Samsung Tab GT-P3113 connects successfully.

    Solved. I notice that my RSSI = 0. Investigate it and turn out that issue is wrong mac address entered in wireless filter.

    I have not yet tried Shibby's new K26RT-AC builds (I will eventually), but found something I thought strange... I changed the channel from the higher numbers, I think 157+161, to 64+60 and am now able to keep a connection on 5GHz (so far). I originally tried the higher numbers because it's my understanding that they use more power...and so provide a stronger signal, is that correct? Could it be that I am too close to the router for those higher channels? I am only a couple of feet away. I am usually wired, but was using 5GHz for testing.

    Anyway, Thanks for reading!

    Higher channels are permitted to use higher power by FCC, intended for outdoor use, but consumer routers operate far below the limits for either band. They probably operate with similar power on our little routers, but we'll never know because Broadcom doesn't share it's driver source code with us.

    There are many more non-WLAN devices that generate interference with the upper band, however. That accounted for the difference in a handful of LANs that I've set up, anyway. The effect of lower frequencies transmitting further is less important because the difference between the upper and lower band is very small.
