    Buffering Issues with ASUS RT-N66U


    I own a ASUS RT-N66U and I have consistent buffering issues (pretty major one at that) and this has gotten worst over time. I can't stream a single 30 minute video without the connection buffering 3-4 times and I'm talking about 30-60 seconds a pop. It's rather annoying. I am also running the latest firmware with my router.
    I have one PC in which my router is connected too. I also have the following devices on my network.

    Apple TV x2
    iPad
    iPhone x3
    IPod

    Has anyone else had this problem? Any help would be appreciated.
    Thank y

    Are all these devices connected wirelessly. If so, that might be the problem, a bandwidth limitation of some sort...eg too many devices sharing the connection will show some lag. In your case the lag shows up while streaming. What is your ISP's connection speed? You might want to see if you can increase it, if at all possible.

    All if the devices are connected wirelessly except 1 of the Apple TV's and the PC that the router is linked to.

    My ISP speed is 5 upload and 35 download. It's the fastest that my ISP offers and they are the only ISP that services the small town that I live in.

    If you disconnect all the other devices from your router (wired, wireless) does it improve?

    When you say " the PC that the router is linked to" are you talking about modem - pc - router or modem - router - pc?

    I mean that the PC is hard wired to the router. I never tried disconnecting any if the devices because I have always felt that since my connection was so fast that buffering should never be a issue.
    I actually just watch a hour long show without any buffering at all. It seems to come and go at will. With that said, I don't know if it is the router or if it's my ISP that is spotty.

    I'm running the same router as an A/P for my garage machine which is using the Asus PCE-AC66 dual band PCI-E adaptor, running the 5Ghz band at 80Mhz bandwidth getting 1.1Gbps very stable.

    Apparently the connection stability between some standard 2.4Ghz devices is not good using the AC66U, even when using the latest Asus firmware.

    There is Tomato and DD-WRT firmware's for this router and there is also the Merlin firmware which is supposed to be much more stable than the Asus firmware. One of those firmware's should be stable for you, I'll post a link to the Merlin firmware which I've heard was stable.

    I will test it out the Merlin's firmware when I get home from work. Thanks for the input.

    Damn fine idea...wouldn't mind doing that myself. Except if your garage is anything like mine, it's a sweat box...how do you keep it cool in the garage?

    I live 1/2 mile from the beach with an endless stream of cool air coming off the ocean it never really gets hot here. It does get into the 80's during summer but I have a big fan in there.

    Here is the wireless speed I get 35 feet from the AC66U which is mounted outside my house under the eves.

    Yet stable firmware remains a problem with this router on the 2.4Ghz band but only with certain 2.4Ghz clients, the Merlin firmware is supposed to make it stable at 2.4Ghz. I personally have no stability problems using the Asus firmware version: 3.0.0.4.354 as I'm using the 5Ghz band

    Would you guys suggest that I stick with just a single band? I utilize both bands. Could that be contributing to my problem?
