    Wifi Signal Through Wall?


    How can I go about improving my wifi signal through walls? My router is located in my living room beside my computer. When I'm upstairs my wifi signal diminishes. This is frustrating and I was wondering how I could go about boosting the signal strength when upstairs.
    By the way, I don't have a cheap router. The ASUS RT-N66U is my router of choice.

    Try disabling the 5 GHz band and just use only 2.4 GHz radio since 2.4 GHz can penetrate walls much better than 5 GHz band.

    Thank you for the recommendation but I'm not sure how to go about disabling the 5GHz band :-(

    If you have a spare wireless router you can set it up as a relay. Put it where it can get signal and it will extend the signal.

    Just figured out how to disable the 5GHz band.
    Question though, how would this help? Would the router use/direct more power into the 2GHz band since the 5GHz band is no longer enabled?

    1. Lower frequencies tend to penetrate solid walls better and gets better range than higher ones. 5GHz frequencies is more easily absorbed by walls while 2,4GHz frequencies is harder to absorb.

    2. I don't think so, if it does so it may cause health issues regarding overpowered wireless radiation etc.

    It won't help at all to turn off the 5Ghz band. The 5Ghz band won't go through walls worth a darn anyway and it doesn't effect the 2.4Ghz frequency which is the one to use if you are going through walls.

    I'm surprised that the 2.4Ghz won't go through your walls, there must be a least three or 4 walls between you and the router because this router has by far the best 2.4Ghz radio on the market. I have the same router myself set up as an access point and it goes through walls like I can't believe.

    It may help to use an 802.11AC dedicated NIC to get the optimal signal from this new wireless standard. Certain wireless devices will have problems connecting to the Asus AC66U so using a dedicated 802.11AC NIC is best.

    The PCI-e versions have antenna's that would help or the USB versions have extension cables to help pick up the signal.

    This would be easier than setting up an access point or wireless repeater and should be tried first. You shouldn't need a repeater with this router because the 2.4Ghz radio is the best on the market, mine goes through 2-3 walls with 5 bars signal strength.

    There are also special antenna's for the AC66U that are supposed to work extremely well.

    And the Asus AC66U PCI-e NIC can help you get the most from your new router.

    You have a few options to increase the range of your wifi signal. One, like escentric stated, you can use an old or buy a cheap wifi router and set that up as a wifi repeater. You could buy a pre-built repeater to match the brand of your wifi router, but those are pricey. You could get some power line wifi adapters, which uses the power lines of your home to create/extend your wired/wireless network.

    You could try and move your current wireless router to a more central location so the signal is spread more evenly. Since this is a multilevel home, that could prove to be difficult. My personal suggestion would be to purchase a reapeater, it's the easiest to setup...plug and go type of deal.

    There are only 2 walls that the signal has to travel through to reach the particular spot in the upstairs level in my house in which my Apple TV and/or iPad are used.
    I actually have one of those Asus WL-ANT-157 Antenna's and I usually have full wireless signal strength at least 95% of the time. With that said, I run into way too much buffering when watching videos on my Apple TV or iPad/iPhone so I assumed it was related to the signal strength. With such a good router I should be running into very little to no buffering and/or slow web page loading. I have a ATV downstairs as well but it's connected via Ethernet to my router and it rarely ever buffers.
    I may just have to go through the hassle of running another Ethernet cable (through and behind walls) to the upstairs ATV to in order to significantly reduced the buffering.
    Running the cable behind walls will be a pain though. I wish there was a alternate method?
    Would purchasing 2 more Asus WL-ANT-157 Antenna at least help at all with the wireless signal when using my iPad/iPhone?

    In that case signal strength isn't the problem.

    If you haven't yet updated the firmware on your Asus AC66U now would be a good time to do so. It may even have something to do with the wireless NIC being used. Some don't work very well with the AC66U, it's best to upgrade to a dedicated 802.11ac adaptor, either USB or PCI-e in order to get the best performance from this router.

    There are countless compatibility updates which requires a firmware update so the latest firmware may help with this problem and should be tried first.
