WRT600N Network Dropouts on 5Ghz Channel with WPA-2

I've got a WRT600N using WPA-2 Personal on the 5Ghz channel. Whenever I try to upload something from my machine to a NAS attached by ethernet to the device I lose the wireless connection. This doesn't happen if I turn encryption off, or if I'm uploading to something on the Net, only a device connected to the ethernet port. It doesn't matter whether I use zero config or Intel Proset. It doesn't seem to matter whether it's the NAS or any other device connected to ethernet port. The same problem happens with every variation of WPA. It's fine if I connect to the 2.4Ghz channel.
I've upgraded to the lastest firmware for the router (1.01.35 build 5) and NAS as well as the latest driver for the intel wireless card. I'm using all the default settings on all the devices.
Does anyone have any ideas why this might be happening with WPA, other settings I could try, anything that might help.

I just used the download - this is on a Vista 32 machine but drivers are available for Vista 64 - http://www.linksys.com/servlet/Satellite?c=L_CASupport_C2&childpagename=US%2FLayout&cid=117523973773....
It's been running fine for the past few months although the router sometimes loses the 5GHz network and I have to restart it. We were away until yesterday and the WUSB600 has been dropping the wireless connection a few times.

  • Please help with WPA (I know I'm close)

    Man, I am completely stumped here, so here goes.
    My wireless device (which has a rt2870 chip) has so far proven itself perfectly capable of connecting to my wireless network....except with WPA. I know for sure that the device itself supports wpa because wpa works under windows and, well, the driver's source code has wpa implementation.
    I have tried using the network profile configured to use wpa as follows
    CONNECTION="wireless"
    INTERFACE=ra0
    SCAN="no"
    ESSID="aptd"
    SECURITY="wpa"
    Key="mykeythatiwillnottellyou"
    IP="dhcp"
    TIMEOUT=20
    and it times out
    In addition, I have also tried configuring that profile to use wpa_supplicant
    Here is /etc/wpa_supplicant.conf
    ctrl_interface=/var/run/wpa_supplicant
    ap_scan=0
    network={
    mode=0
    ssid="aptd"
    scan_ssid=0
    proto=WPA
    key_mgmt=WPA-PSK
    auth_alg=OPEN
    pairwise=TKIP
    group=TKIP
    #psk="abc"
    psk=abcdefghijklmnopqrstuvwxyz
    priority=0
    and it still times out >_<
    So right now I am hoping I can get some help from fellow arch users.
    Does anyone have any ideas?
    By the way, I have my router set to accept both TKIP and AES so it should allow either encryptions, right? or could that be the root of the problem?

    Well, I tried setting TIMEOUT to two minutes (120 seconds) and that didn't help.
    By the way, here what the wiki asks

    I have a new iPhone 4s.  I have a home wi-fi network using Cisco Linksys2000 router with all settings per this article - phone will not see network if set to 5 GHz channel width - solution??  2.4 works but is not optimal with other devices in home (computers; tivo).  Have others seen this?  Any advice is much appreciated.

    Stephen Spark is right - your best alternative is to use a simultaneous dual band wireless router like the AirPort Extreme. Your Cisco Linksys2000 is not a dual band router, meaning that it will be constrained to operate at the slowest speed of all the devices on your network.
    The AirPort Extreme's dual networks will support all your 802.11n devices as well as all your 802.11b/g devices on both the 2.4 and 5 GHz frequencies simultaneously.

  • Can I extend both a 2.4Ghz and a 5Ghz wireless network at the same time with a second Timecapsule / Extreme ?

    Can I extend both a 2.4Ghz and a 5Ghz wireless network coming from a Timecapsule  with a second Timecapsule / Extreme at the same time?

    I am currently extending my 5Ghz network via an Express without any problems, but the Express can only extend either / or. I just want full coverage for both networks in the whole house.
    If you can extend 5 GHz now with an AirPort Express and get satisfactory results, then the AirPort Extreme will work to extend both the 2.4 GHz and 5 GHz bands in the same location.
    However, your computer is going to connect to the band with the strongest signal, so it may....or may not....connect to 5 GHz given a choice of two signals.

  • Problem with wpa and hidden ssid

    hi,
    I have a powerbook g4 (1,67ghz). i am having trouble connecting to a netgear router mr814 v3 if i use wpa and hidden ssid, i get a message, that the router would not support wpa!
    there is no problem with wep and hidden ssid or wpa with no hidden ssid.
    is also have no problems with wpa and hidden ssid with an ibook.
    the problems occur only with the powerbook with os x 10.3.9 as well as 10.4.2. even after the recent airport update, no change.
    thanks for the help,
    ben

    I would use WPA and broadcast your SSID.
    It use to be useful, but closing your Airport or wireless network (sometimes referred to as not broadcasting your SSID) is really no longer a real option when it comes to wireless security.
    Unfortunately "Closed" networks, MAC access control lists, and reduction in transmission power are all more "feel good" security rather than real security. All these various approaches are dated and mistakenly lead to overconfidence.
    WPA is your friend if you value wireless security.
    My recommendation is not to worry about broadcasting your SSID but use WPA. This will be more secure than a closed WEP encrypted network. Closing your network makes it very difficult for neighbouring networks to see which channels are free thus causing potential interference problems.
    Another thing to consider is that a closed network is still broadcasting and therefore is detectable (regardless of whether it is broadcasting a SSID). If someone was determined to hack into your network, then not broadcasting your SSID and MAC address access control is not going to stop them.
    WPA is virtually uncrackable (only really vunerable to a dictionary attack if a real word is used as a password) and therefore will stop the casual user and the determined hacker.

  • 5GHz channels no longer available after upgrading to 10.7.3

    I'm currently using Late-2009 iMac and for some reason after upgrade to 10.7.3 I couldn't connect to any 5GHz network at all. In the System Profiles, Wi-Fi menu now says:
      Interfaces:
    en1:
      Card Type:          AirPort Extreme  (0x168C, 0x8F)
      Firmware Version:          Atheros 9280: 4.0.61.4-P2P
      MAC Address:          04:1e:64:ec:f6:e2
      Supported Channels:          1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13
    which now lacks the upper channels previously supported (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 34, 36, 38, 40, 42, 44, 46, 48, 52, 56, 60, 64, 100, 104, 108, 112, 116, 120, 124, 128, 132, 136, 140, 149, 153, 157, 161, 165); I wonder if this is intentional, if so, for whatever reason did Apple decided to disable 5GHz support for this particular build (which previously worked flawlessly)

    Interesting. If you can still connect via wired (or 2.4GHz wireless), I would download the 10.7.3 combo update from apple support and reapply it. It appears the driver and family did not fully install with the update.
    You can get the update here:
    http://support.apple.com/kb/DL1484
    If you re-install the combo update and you still do not have 5GHz channels, please open the System Information tool and post all of the text you see on the right for WiFi. E.g.:
      Software Versions:
      CoreWLAN:          2.1.2 (212.1)

  • Airport Extreme 5GHz Channel not available

    Hi All
    My Airport Extreme 5th Gen is now up and running.
    The issue I have is that unless I give the 5GHz channel it's own name, my MacBook Pro will not pick it up - instead opting for the 2.4GHz channel. I know that distance and obstacles are a factor but in a test situation the MacBook is only a metre away from the Airport. If I give the 5GHz channel it's own name then I can select the 5GHz network and confirm the connection rate - this also works with Windows 7 machine in the same position with the signal strength being 'excellent'. So why when I have the same name for both channels will my machines only pick up the 2.4GHz signal?
    Using two names would be okay exept that when I do this the 2.4GHz network slows completely and is unusable.
    Last week I had a pretty good setup with an old Airport Extreme and now with the new 5th Gen unit I can either connect two machines at 5GHz or four machines at 2.4GHz - not a mixture of both. So basically I'm no better off than with my eight year old Airport Extreme.
    I'm beginning to think that there is a defect with the new Airport Extreme unit - is there any simple checks I can do on the unit to confirm that it is operating correctly?
    I'd really appreciate any help with this.
    Phil

    Update: Solved. I reset the Airport Extreme a number of times in succession and finally it just worked - not sure what the problem was.

  • Connect MacbookPro and AirPort Extreme via 5Ghz channel

    Hi.
    I have three Apple devices:
    - Macbook Pro 13" 2012 year (802.11n wi-fi standart)
    - iPad mini with Retina 2013 year (802.11n wi-fi standart)
    - Airport Extreme 2013 year (with support 802.11ac wi-fi standart)
    By default, a macbook device connected to the channel 2.4Ghz. Connection speed is set 217 Mbit/sec. If you divide the channels 5Ghz and 2.4Ghz, then the connection speed to 450 Mbit/sec on channel 5Ghz.
    How to configure AirPort Extreme when macbook and iPad was connected to the AirPort using 5Ghz channel by default?

  • Turn off 5Ghz channel?

    Have the latest TC but downloading files and viewing videos much slower on 5Ghz than 2.4.  Is there a way to turn off the 5Ghz channel?  if not, my MBP automatically connects to the 5Ghz channel. Is there a way to make the 2.4Ghz the default channel the laptop connects to?.

    Open Macintosh HD > Applications > Utilties > AirPort Utility 6.0
    Click Edit
    Click on the Wireless tab
    Click Wireless Options
    Enter a check mark next to 5 GHz Name and this will automatically add "5 GHz" to the current wireless network name that you use.
    Click Save and the Airport will restart with the new settings in place
    Your devices will now connect to the 2.4 GHz band
    If you want to connect to the 5 GHz band in the future, you will need to "point" your computer at that network

  • Problem with WPA and ipw3945

    Oi, it is me again ...
    I have a problem when trying to connect to my wireless router using WPA. The wireless works as long as I leave WPA of, and when I try the same configuration with WPA on an other notebook it does work. I have loaded ipw3945 and started ipw3945d. Without WPA the following woks correct:
    iwconfig eth1 essid network

  • I have a 3rd generation iPod Touch and just did the update to IOS 5. Now I can't connect to my Netgear wifi router. My iPhone connects fine along with all of my other laptops etc. I have the router set with WPA-PSK [TKIP] security and an access list.

    I have a 3rd generation iPod Touch and just did the update to IOS 5. Now I can't connect to my Netgear wifi router. My iPhone connects fine along with all of my other laptops etc. I have the router set with WPA-PSK [TKIP] security and an access list. I've confirmed the mac address is included on that list and that the password is correct. Under choses netwrok I select the network and it just goes into a spin. I have tried removing the password and the access list settings and it still will not complete the connection to the router thus no internet access. The routers firmware is also up to date. This thing worked fine before this update and I've already tried to restore from backup. Any ideas or is the wifi nic bad in this thing with the new apple firmware update? Any fix?

    Thanks Bob, I don't know why but it all of a sudden worked a few days later. It's a mystery but at least problem solved.

  • Can't connect to Netgear router with WPA enabled (MBP)

    I just received a Macbook pro today, everything is wonderful except wireless networking. When it first started up, it detected my wireless network, showed me the SSID, and asked for a password. I entered the password, and it failed to connect. I decided to try later and did the rest of the install.
    I connected via cabled ethernet and downloaded all of the updates. For a machine that shipped from the Apple store (custom config) a few days ago, I was surprised at having 13 LARGE updates to download. Grabbed them all, including a Firmware update which required two reboots. One for everything else, and another for the firmware.
    I tried again from sysprefs, and asked for the diagnostics. It asks me for my WEP key, and there is no option for WPA. I tried entered the WPA key anyway, despite only three WEP options showing up, and it still fails.
    Going through the Airport 'tab' and editing the connection, I get an option for WPA Personal, Enterprise, WPA 2 Personal, and WPA2 Enterprise as well.
    I tried using WPA Personal and WPA 2 Personal and entering the key which works on other notebooks, still no joy.

    Which Netgear router do you have? I use the Netgear
    RangeMax WPN824 and works well with WPA enabled but I
    think it may have failed to work the first time.
    WGT624 v2. Works fine with other wireless devices from a number of vendors, and is detected by the Mac, but I can't connect. I don't want to disable WPA if I can help it, I have a number of other systems configured for it as is, plus guests that come to visit.
    but some how I had to delete the connection,
    let airport find it again and re-enter the password
    to get it to work. One of those things I kind of did
    in the process of troubleshooting and can't remember
    exactly how it was I did it
    I'll try that and see if it helps. Thanks for following up.
    UPDATE: Sure enough, I deleted the network and added it back in by manually specifying the SSID and password, and it works now. No idea why, but there it is... thank you very much.

  • AX will not work with WPA

    My AX worked successfully with WPA security for several months, then stopped. I reset it, hard and soft, used factory default, but it would not work with WPA. Changed the security to WEP 128 and it worked fine. But now my Macbook Pro won't connect automatically. I have to run diagnostics to reconnect every time I started the computer.
    Went back to WPA, now my Macbook Pro connects fine again, but the AX won't won't connect. Airport utility recognizes it when I reset it, but when I go thru the configuring process with Airport Utility, AX always fails on the last step, saying it could not join the network after it restarted.
    Does this make any sense to anyone?

    Henry,
    Thank you for explaining Duane's approach. Immensely helpful! And, of course, in retrospect, makes complete sense. I'm sure there is a kb article on this somewhere....... ?
    Which brings me to something in your post:
    "do a hard reset of the Airport Express and use the Airport Setup Assistant to reconfigure it from scratch"
    Am I missing something here because after installing Leopard, Airport Utility is the only Airport app I have in my Utilities Folder? I do remember Airport Setup Assistant being part of Tiger (but that disappeared as did the functionality of several other Airport apps (Airport Admin, etc.) after upgrading to Leopard.
    So, IS there an equivalent in Leopard of the Airport Setup Assistant? Or do I use the Network app in Sys Prefs to Join an already existing network (going the route of a hard reset of AX)?
    Usually, David Pogue's MM book on OS X is helpful in filling in the gaps, but his new Leopard book seems a bit sketchy this time on setting up a wireless network. I think this subject (setting up a wireless network, etc.) could almost get a MM of it's own!
    If I may, can I address a related issue? Previously, in setting up the AEBS and AX to work together you do end up with what LOOKS like TWO networks (both have their own Apple network numbers and letters) even though they are working in tandem as 1 network, right?
    I bought the AX to extend the range of my network because it seemed the signal from the AEBS was not quite strong enough. I set it up to be a "remote" to the AEBS's "main." I also use the AX to stream iTunes to my living room's sound system.
    Again, many thanks for your help.

  • Wmp 11 pci card work with WPA encription?

    I just purchased a new 54G wireless access point since my new laptop (with Vista) doesn't seem to want to give "full connectivity" when using WEP security activated.
    I now use WPA and the laptop hooks up fine to the new access point.  My problem now, is all my other wireless computers have the older wmp 11 pci cards, and I don't see anywhere in the setup where I can select "WPA" security so they can see the new access point.
    Is there a way that they can work with this new access point with WPA?

    I have a WMP 11 2.7 - I know for a fact it supports WPA2 because I am connected to the net using it and WPA2 right now.
    I knew it had to work cos I got it working under Ubuntu linux using this
    http://ubuntuforums.org/showthread.php?p=1071920&mode=linear
    very helpful guide.
    Could not however get the damned thing to work on windows using any of the drivers from this site. So I went back and had a look at the linux guide and found a simple solution. Download this driver
    http://sidulus.textdrive.com/bcmwl5sys.zip
    Go to C:\windows\system32\drivers\bcmwl5.sys rename the driver there to bcmwl5.old.sys and unzip the new driver to that location. Restart. Hey-presto you should now be able to connect to WPA and WPA2 networks.
    I think this will probably only work for the 2.7 version as that is a Broadcom chipset.
    You know what really bugs me tho? I shouldn't have to be telling you to do all this, I shouldn't have to do it myself either. Why the hell does this card not connect to WPA with the drivers supplied on this site?!?!?
