    Wifi Signal Through Wall?

    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.

    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.

    I have tried the official Asus software before and I have found that Merlin's is more stable so I have been using it instead.

    I didn't realize that a 802.11ac adaptor would make any difference at all because it would be considered part of my PC's hardware. How does PC hardware affect the wifi signal from the router which is a separate piece of hardware?

    My current network card is the ASUS PCE-N13

    Yes the adaptor makes a difference because your new router is made to work with the new wireless standard 802.11ac, where the adaptor you have now is made for 802.11n, this can be problematic in many cases.

    In fact many people have reported the same problems as you and all of them were with the older wireless n standard NIC's. Upgrading to either a USB or PCI-e NIC that is made to work with 802.11ac solved the problems in every case.

    As I mentioned before there are many wireless N devices that do not work very well with this new standard and I believe this is the problem you are having now. Use either firmware as long as it's updated and yes I was aware of the Merlin firmware although I have no stability problems using the latest Asus firmware.

    You will have better luck with the Asus AC66U PCI-e NIC as this was made to work with your new router using 802.11ac. Or you could try the USB versions.

    Here are the wireless speeds I get using the 5Ghz frequency from 30 feet away outside my house with no walls and a few palm trees in the way from the A/P. 2.4Ghz maxes at about 450Mbps but for either of these you need an 802.11ac dual band NIC.

    I was looking at some of the newegg reviews for your router to see if anyone had the same issue as you and it looks like there are people that have connectivity issues. Asus support recommended to them to update their firmware just as Chev65 suggested. I have provided here the link for your router's firmware download page. Something else I noted was that for a few people upgrading the firmware seemed to "brick" their router or basically stop the Wifi from working at all. If this happens to you I have provided a youtube link on how to do a firmware restore, link was also included in a support reply from Asus on newegg.

    *the video shows the RT-N56U router but the steps are the same on the RT-AC66U.

    I think there has been a misunderstanding unless I'm missing something here.
    I own a ASUS RT-N66U router, not a RT-AC66U router :-(
    My router is a N router right?

    My apologies, I looked up the wrong model of the router, you may disregard my post.

    Thank you got everything. Regardless of the fact, your effort to help was appreciated.
    When I purchased this router a few months ago, I should have bought the AC version. Live and learn I guess...

    Would the extender still be a recommendation or am I'm just screwed?

    You always have the option of upgrading your PCI-E NIC card or a USB variant to what Chev suggested.

    I would say it would do the trick. imho, there is too much emphasis on "going through walls". I am sure your problem is one of range, although I would admit the two can be contributors. What range are you trying for, when you are upstairs?

    I live in an old sprawling farmhouse. This has Rockwool insulated clay walls. Previously I was using an antique Linksys router. This got me a usable signal upstairs, about 20 mtrs. Free courtesy of my ISP, I recently installed a new router and can now get a strong signal in one of my further buildings, about 30 to 40 mtrs.

    But, on reading an article on the web, I hitched up the old Linksys as a repeater and now have full and strong coverage over my whole building(s)

    My point is that, within reason, don't spend too much money on another new router. It doesn't have to be too demanding and a purchase from the s/h market should suffice.

    Thank you for all the suggestions. I have one more question though. What does this indicator mean on the screen shot? The Wifi icon is only half lit.
