802.11ac

Hello dear community,
I just wanted to share a quick insight with you. I have purchased two of the new Airport Extreme 802.11ac stations yesterday, and have now finished the setup. My layout looks like this :
[FritzBox ADSL router] <---- cable ----> Airport Extreme 1          {wireless}          Airport Extreme 2 <---- cable ----> MacMini
[QNAP TS-291Pro] <---- cable -------------^
The two airports are roughly 6 meters from each other (around 20 feet) and don't have direct line of sight. The #2 is configured to 'extend' the first's network.
I get constant 30 MB/sec transferring files from the QNAP over to the MacMini, which makes me a very happy camper!
At first I didn't get that kind of bandwidth because I made the mistake to configure the 2nd airport (the one connected to the MacMini) to be a client on the first's 2.4 GHz wifi network which only gave me access to the b/g/n network. After I changed this to be a client of the 5 GHz (ac) network, I achieved the speeds I was hoping for.
I also do have almost full coverage throughout our house (3 stories, armed concrete walls and floors).
A very nice looking, and very well working product they have built there!

Hi @Fred-x ,
Thank you for visiting the HP Support Forums and Welcome. I have looked into your issue about your HP Pavilion 17-f002na Notebook and not connecting to the 5Ghz channel
I have searched Microsoft for a fix for this and they indicate on the forums that if you change the router channel to 36, this will resolve the 5 GHz connection issue.
 You could turn off IPV6 for the notebook. Some say this helps. Some also indicate to turn off the 5GHz all together.
 Fix this problem Microsoft Fix it 50413
Hope this is helpful.
Thanks.

  • Can my mid 2011 macbook air be upgraded to wifi 802.11ac?

    Can my mid 2011 macbook air be upgraded to wifi 802.11ac? I am considering replacing my 802.11n router with the 802.11ac time capsule. Will this effect my download speed on my 802.11n macbook air (mid 2011)? can it be upgraded?

    No, you cannot change the Wi-Fi hardware in your Mac. The Time Capsule is still worth it due to its ability to make backups of your Mac via Time Machine.

  • Trying to Port Forward Airport Extreme 802.11ac using Airpot Utility 6.3.2

    Hello kind experts. I am finally getting around to replacing my old BEFSR81 Cisco Router with an old Time Capsule attached with the Airport Extreme 802.11ac.  The BEFSR81 also had 8 ports, so I have 8 hardwired locations throughout the house.  I have a couple of IP cameras for which it was easy to port forward on the Cisco (just click on the port range forwarding tab, type the start/end ranges (which are identical) and the assigned IP address).  Everything has been working well for years.  Here's what I wish to do with the new setup: Cable Modem -> Airport Extreme -> Dumb gigaport switch with the hardwires connected to it.
    When I go to Airport Utility (6.3.2) -> Network Tab -> Port Settings -> "+", the following comes up:
    Firewall Entry Type (Defaulted to IPv4 Port Mapping)
    Description (5 pull down choices)
    Public UDP Ports : _________
    Public TCP Ports: __________
    Private IP Address (I take it that is where I enter the IP address for each camera, e.g. 192.168.1.xxx)?
    Private UDP Ports: __________
    Private TCP Ports: __________
    I am obviously not a technophile, especially when it comes to networking, but was able to create my old setup.
    Any advice on whether or not my configuration is appropriate and what exactly I need to put in the port fields would be greatly appreciated!
    Thanks in advance!

    To successfully access an IP camera on the local network from the Internet, the following basics need to be taken care of:
    Install the camera(s) and verify that you can access them from the local network.
    Configure port mapping/forwarding on your router. Typically, IP cameras require at least two ports: 1) A web port for administering the camera; Usually TCP port 80, and 2) A streaming port to broadcast the camera video feed; Usually UDP port 9000. Note: You should check with your camera's documentation for the exact ports required.
    If the camera is attached to a computer, you will need to configure the computer's firewall to open the same ports as in step 2 above.
    Verify that your modem is in bridge mode, i.e., if the modem provides NAT & DHCP services, turn them off.
    Test your network. Use CheckIP to determine your router's current WAN-side (public) IP address. Then, from a remote location (not from a computer on the local network), use the DynDNS Open Port Tool to verify that the required ports are open. Success is an "Open" response from the Tool.

  • Airport Extreme 802.11AC + 5th Gen and guest network access

    I have the current gen Airport Extreme 802.11AC with a 5th Gen extending the network. With this setup, I am unable to login using our guest network setup. I have tried using guest network with a password and one without but its the same results. When a guest logins, it stuck attempting to login with no error messages.
    So is it possible to have this configuration and still have guest network access?

    Please review what I said originally.......that the guest network function on the AirPort Extreme is designed to work with a simple modem......so the AirPort acts as the main router for the network..
    Another way of saying the same thing is that the AirPort needs to be "in charge" of your network for the guest feature to work correctly. The AirPort cannot be in charge if it is connected to another device that is already configured to be the main router on your network.....your Actiontec modem/router.
    The Actiontec device combines the functions of a separate modem and a separate router in one package. This type of device is known as a modem/router, or also known as a gateway.
    Some folks call a modem/router or a gateway......a modem. So, things can get confusing.
    I do not know if it is possible for the Actiontec device that you have to be configured to act as a simple modem.....so the routing functions of the device are completely turned off. (Turning off the wireless on the Actiotec does not turn off the routing function).
    If you turn off the wireless on the Actionec, it becomes a modem and a wired router. And that wired router is still in charge of your network.
    The guest network feature will not work correctly unless the AirPort is in charge of your network.
    My suggestion was for you to ask your Internet Service Provider (ISP), if they could supply you with a simple modem.  That is all that you need. You don't need two routers....and the Actiontec that you have now is not allowing the guest feature to work correctly.

  • Issue with new Airport Extreme Base Station 802.11ac

    I just purchased an AEBS (new model with 802.11ac).  I'm using it with Comcast internet service using a Motorola Surfboard SB6121.
    I have a very odd and frustrating issue.  The internet simply blips in and out.  I have it set up with WiFi and have connected devices such as my iPhone, iPad, Mac Pro, and a Chromebook to it.  I have the issue on all devices so I know it's not device specific.
    The network itself never goes away.  When I look at the WiFi area on my Mac even when the internet isn't working it shows it's connected to the WiFi network.  Also, when the internet is not working the green light is on and staying lit (not blinking) on the AEBS so it appears the WiFi Network part of it works fine.
    As mentioned it's the internet service itself that blips in and out.  What I mean by this is it may come on for 40 secs, go off for 20 secs, back on again, and off, just like that. I have not timed it and that would be hard but it seems to be very regular, something like 40 on, 20 off, and it may not even vary at all.  It's a very bizarre issue.  I have also direct connected the modem via ethernet to my Mac Pro. I used it for several problems with no problem so I know it's not the modem.
    The only thing I can think of is I received a defective AEBS.  I purchased it through Amazon and I almost contacted them to do a replacement and send this one back.  Yet I'm hoping it's something simple with the settings.  Now I have already done a factory reset of the AEBS and that did not help.  Yet I'm hoping it's simply a setting that I need to modify or wipe out.  Any idea of what's causing this or is it simply a defective base station?
    Thanks for your help.

    There is a bug with the modem where the ethernet is not syncing properly.. The bug is particularly bad with SB6121 and SB6141.. so you got it right.. welcome to the bug farm..
    https://discussions.apple.com/search?q=sb6121
    https://discussions.apple.com/search?q=sb6141
    There is no solution.. a new one could do the same. It is not 100% consistent.. I have recommended people use a small 10/100 switch between the modem and the AEBS.. or use a cross over cable. It works for some but not everyone.
    Some modems seem to work better.. but IMHO it is not your problem it is apple's.. and they are keeping quiet as they do.
    Send the AEBS back either for replacement.. and hope for a better one.. or just get a refund and buy something better.. eg Netgear R7000 or Asus RT-AC68U.

  • Setup Problem New Airport Express 802.11ac

    Current setup is: 
    Cable Modem to Linksys Router to Ethernet Switch to Airport Express 802.11n (in bridge mode).
    Airport Express is plugged into the ethernet switch and set to a fixed LAN address.
    Everything works fine and reliable.
    Just bought a new Airport Express 802.11ac
    Plugged it into another ethernet switch port and tried to set it up the same way (bridge mode), but used a different fixed LAN address and different wireless network name.
    I get a warning message that it cannot get a DNS.
    I go ahead anyway and it doesn't work.  Router hangs and has to be rebooted.
    When I set the new AEX to "extend existing network", it works ok.  But I assume that in this mode I'm still limited by the speed of the old 802.11n device, which is between me and the router and modem.
    What is the reason that I can't have two AExpress units both in bridge mode tied to the same router?

    ... But I assume that in this mode I'm still limited by the speed of the old 802.11n device, which is between me and the router and modem.
    Correct. Also, you won't be able to use 802.11ac anyway unless you are using a new MacBook Air or other device capable of  802.11ac.
    Make sure that the AirPort Utility setup screen did not say "Setting up this AirPort Express to wirelessly extend (your network name)".
    The words you must see are "Setting up ... using Ethernet".
    If necessary, set it up again beginning with a "hard reset" and verify that is the result. Leave it connected as you described when you do. Your proposed configuration should work.

  • How to Setup Airport Time Capsule 802.11AC on Verizon fios

    I just got an Airport Time Capsule 802.11AC and i would like to set it up on to my existing verizon fios router as you can't change their router as the cable box works with it does anyone know how to do such a thing?

    Setup is amazingly quick and easy, assuming that you connect a permanently installed Ethernet cable from one of the LAN <--> ports on the Fios router to the WAN "O" port on the Time Capsule, and then use AirPort Utility on your Mac or iPhone/iPad for the setup.
    We need to know what operating system you are using on your Mac to provide any specific setup details. Or, let us know if you are going to use an iPhone or iPad for the setup.
    The Time Capsule will set up another wireless network, so if  you do not need two networks, you can turn off the wireless on either the FIos or Time Capsule. If you decide to have two networks, be sure to separate the Fios router and Time Capsule by 5-6 feet or a few meters.....to minimize the chances of wireless interference occurring between the two devices.

  • I have airport extreme 802.11AC as a base that connect to Cable modem. How can I connect D-link DIR-655 to AE to utilize as an extender or repeat?

    Hello-
    I have wireless router Airport Extreme 802.11AC that connect direct to Cable modem...how can I setup the D-Link DIR-655 wireless router to AE and act as extender or repeater?. Thanks in advance.

    Apple has done their best to install proprietary software in their wireless routers that is designed to only allow other Apple routers to repeat or extend the network wirelessly.
    So, the chances are extremely small that a D-Link....or another other router for that matter.....could be configured to do what you ask.
    There are no settings on an AirPort Extreme that would allow a D-Link device to extend the network, so all that you can do is experiment with different settings on the D-Link device to see if it might be possible for it to extend the network.
    A post on a D-Link support forum might be a good idea to see if any D-Link specialists have some ideas on this topic.
    Good luck.

  • Macbook Pro 15" (late 2013) - Cant get proper 802.11ac WiFi-speed. Mac or router issue?

    Hey
    Im from Norway and just bought the 2013 Macbook Pro Retina 15 inch. My router is an Asus RT-AC66U, which should be capable of 1.3 Gbps connection speeds. When i connect my mac to this router on a 5 GHz network with N+AC only mode, i only get a link speed of about 200Mbps, often lower aswell. I was under the impression that you should get the theoretical maximum speed of the 802.11x youre using, as link speed. When i go to "about this mac"-"system report"-WiFi" it clearly says that im connected with 802.11ac. Why do i get such a low transmission rate? Its a problem with bootcamp aswell (Windows 8.1), which leads me to belive that the router mighth be the issue?

    It seems that i have found a solution to the problem, but at the same time encountered a new one. The router was the problem. I live in an apartment building with many other students, and there are tons of other WiFi signals from other apartments. The router was in N+AC (there doesnt seem to be an AC only mode as of now?), and the signal strenght was around -40dB (Macbook placed three meters from router with no obstacles in the way). I downloaded a program called inSSIDer for Office and scanned all the network and associated channels and it turned out the router hadn't exactly choosen the optimal channel. When I changed the channel to a less populated one (44), the link-speed suddenly jumped from around 200 to a little over 1000 Mbps. I really didnt know just how sensitive to interferrence WiFi truly is.
    The strange thing in windows though is that even though the linkspeed is great (i get much lower link-speeds in Windows, 400-600 (seems to be stuck at 802.11n in windows) compared to 800-1300 in OSX) i max out at 30 Mbps download (speedtest.net), while upload speeds remains unaffected at 94 Mbps (100/100 Mbps subscription). And when I turn on automatic channel selection on the router the link speed goes down to about 200 again (because of the interference issue), but the download speeds go up to 94 Mbps. This is not an issue in OSX, so maybe its an Windows Boradcom driver issue or something?

  • 802.11ac not recognized on Windows 8.1 Pro under Boot Camp.

    I just installed Windows 8.1 Pro under Boot Camp. The issue I am having is that the 802.11ac network is not recognized in Windows. Windows only recohnizes the 802.11n network. When I boot up OSX Yosemite, It works as usual. Anyone else have this problem?

    8/8.1 will install fine but there's some stuff you need to do before starting to ensure no issues
    purchase a retail 8/8.1 license
    use only a USB2 flash drive
    get a clean 8 or 8.1 ISO
    newer machines are more selective with the ISO for some reason (ISOs that worked to install Windows on many different older Macs would not work)
    if you've made lots of changes, hacks and adjustments trying to get this work on your own, you should clean install OSX first, do not restore from time machine and start at step 3 to get Windows installed, you can go back later and copy files back to OSX
    if you want to try without clean installing OSX, here goes
    open boot camp assistant (bca) and choose option 3 ONLY if it reads 'remove/delete' Windows
    open disk utility (du) and confirm that your HD now only has 1 single partition ('macintosh HD' unless you've renamed it)
    restart machine and do a PRAM reset
    open du and repair permissions TWICE
    open bca and choose all 3 options (create, download, install)
    from here, the process follows the standard boot camp instructions (http://manuals.info.apple.com/MANUALS/1000/MA1636/en_US/boot_camp_install-setup_ 10.8.pdf) but pay attention to step 3 where you do have to manually reformat the boot camp partition
    clean ISOs

  • What network adaptors support 802.11ac?

    I want to purchase the new airport/time capsule mainly for it's 802.11ac capabilities. I have a mid-2009 macbook pro.
    Wondering what network adaptors are out there that I can plug into my usb that can support 802.11ac? I found some but they only support Windows.

    Newer AC wireless would need to support USB 3 standard but of course that is not available.
    I want to purchase the new airport/time capsule mainly for it's 802.11ac capabilities. I have a mid-2009 macbook pro.
    You only have one port that is near capable (actually more than capable if real numbers are used) and that is ethernet. So the best device for you is a second Airport Extreme working as bridge or extend wireless in apple terminology.. really it is not such a bad option since the cost of AC usb 3.0 will be over $100 anyway.

  • New late 2013 MBP Retina not using 802.11ac

    Hi, I recently started to use a late 2013 15" Macbook Pro Retina with the newest Time Capsule.  However, it's not connecting with 802.11ac.  Rather it's using 802.11n.  Is there a setting that I need to change to "force" it to use 802.11ac?  Of note, I'm using 10.9; I haven't upgraded to 10.9.1 yet.

  • Linksys WUMC710 bridge crashes Airport Extreme (802.11ac) network

    I have just bought the Linksys/Cisco WUMC710 802.11ac bridge to use with my Apple Airport Extreme (the 802.11ac). After resolving some channel related issues getting the Linksys to see the network, I now find that after about 30 seconds of having the Linksys on the wireless network, it causes the Airport to go into an error mode (orange flashing light) and the whole wireless and wired network (running through the Airport) fluctuates or disappears entirely. Powering down the Linksys restores everything back to normal.
    I am on latest Airport firmware, and v1.0.1 for the Linksys. The Linksys is about 5m away from the Airport at the moment. Security is WPA2 personal.
    Any thoughts on what might be causing this?

    Hello
    I tried to set the WUMC710 (Firmware 1.00.18) and Airport time Capsule 2TB (Firmware 7.7.3) and I could not in any of the ways ...
    Any solution??

  • Late 2013 rMBP 13" 802.11ac problem

    I've got a brand new 13" Retina MacBook Pro 13" (the 512GB i5 model)...and after a rather strong showing at first, it falls absolutely flat when attempting to connect to the 5GHz side of my wireless router.
    Specifically, this:
      Current Network Information:
    yannnet 5G:
      PHY Mode:          802.11ac
      BSSID:          10:fe:ed:xx:xx:xx
      Channel:          149
      Country Code:          US
      Network Type:          Infrastructure
      Security:          WPA2 Personal
      Signal / Noise:          -56 dBm / -92 dBm
      Transmit Rate:          27
      MCS Index:          1
    As you can see, this isn't a weak signal problem. In fact, I've got multiple other devices (mid-2009 MacBook, 27" 2011 iMac, Nexus 5, iPad third-gen) that connect to that network just fine, whether at 11ac speeds (the Nexus 5, at a full 433 Mbps since it only has one antenna) or at 11n speeds (for all other devices).
    2.4GHz appears to have sporadic issues as well, but it's better than 5GHz. Ethernet via a USB 3.0 adapter seems to work fine.
    I've got Mac OS X 10.9.2 installed. Any idea what's going on here? I've cleared preference plist files etc., and that only seems to help for a minute or two.

    Go ahead an exchange it for a different machine - 95% health is just not acceptable for a new machine.
