Airport Authenticating on WPA secured network

I recently upgraded to Leopard, but did a new install and am having problems with my wireless network at my school. We use WPA encryption and download a certificate from an unsecured wireless network and then once we have the certificate we use 802.1x to log on to the secured network. Mine works fine for awhile, and then every like 10 minutes it cuts me off of the network and reconnects assigning itself its own IP, no one else on Leopard is having this problem. I know that in Tiger, we were supposed to put the certificate that we downloaded in x509 in order to make sure it would always connect, but since Leopard doesn't have those I put it in system. Does anyone know how I need to re set this up?

Honestly, I was pleasantly surprised to see how easily 802.1x configured itself and worked in both Tiger and Leopard.
Try going into your keychain access and deleting anything having to do with your 802.1x configuration or a cached authentication ID out of all of the keychains.
If you're using any sort of one-time password, make sure that you don't save it. If I recall, there is a box someplace that says something to the effect of, 'This is a single use password' when you get prompted for auth.
Also, make sure that you have all the correct protocols, such as EAP-FAST/PEAP enabled for your environment. It may be trying to re-key every now and again and you're failing there.

  • Orignal Airport card with WPA security

    I have two machines as follows:
    iMac G5, OS 10.4.6 with Airport Extreme
    iMac G4, OS 10.3.9 with original Airport card.
    Airport Express connected to cable modem (firmware v6.2)
    WEP 128 security.
    When I originally set up my wireless network, the G4 would not connect with other than WEP security. There was nothing in the documentation that indicated that this would be a problem. Even the Apple Care guy was not aware of it. I don't remember how long ago this was.
    Everything works great, but I'd like WPA security. Rather than "break" something that's working, I thought I ask this forum for some wisdom.
    Has something been updated, either on the Mac side or the Express side to eliminate this "problem"?
    Thanks for the help,

    As long as you are using AirPort software version 3.3 or better you shouldn't have a problem connecting to a WPA network. See AirPort Card: When You Can Join a WPA Network.

  • IPod touch won't work with WPA secured network

    I'm trying to put my touch on my home network which has WPA security. I have a problem in that one of the characters in my 50 characters WPA key is not available on my iPod! (The " ` " character. It's not an apostrophe like " ' ". It's the one on the tilde button.) I don't even know if I had that character that it would work. Is there anyway that I can change my WPA key, or have a simpler password? It seems like I shouldn't have to input like 50 characters if I want to access my network. Is there something I configure in my network settings? Any help is appreciated.

    I use WPA2 and have no problems connecting. I must clarify that I have a mixed network of Airport Extreme 802.11n (operating on 5GHz) & 802.11g (operating on 2.4GHz) routers. Only the 802.11g router's network shows on the Touch though.
    You should replace the character that's not on the iPod in your network password. It should work if it's operating on the standard (default?) 2.4GHz. I don't think that 802.11g or n matters. As for entering the password on the Touch every time you want to join your network, that won't be necessary. I just double -checked. The network name and settings are memorized by the Touch.

  • Satellite A300 - won't connect to WPA secured network

    Help please.... new Toshiba Satellite A300 - running XP professional with atheros AR9281 wireless network adapter (driver 7.6.0.200) won't connect to WAP secure networks, but seems to be fine with WEP and unsecured networks?
    I can connect to my WAP secure network using LAN cable and also if I use an external Netgear wireless adapter, so the problem is definitely with this adapter or driver. I have update bios and tried updating driver, but no luck. Current driver is (I think) most up to date?
    Would be grateful for your help.
    Thank you.

    On the Toshiba website is a newer driver version available (7.6.1.149.1)
    So I would try the new driver.
    Check the Toshiba website:

  • Can ibook with built in airport detect a private wpa secure network?

    I have an ibook g4 with built-in airport. My home supports a d-link wirless router on private broadcast and wpa-psk security. The ibook has no problems linking to the router and the network but when the ibook goes to sleep or is shut down, it drops the connection. When I awaken the ibook or turn the ibook back on, I have to enter the SSID and the password every time. Is this normal for airport?
    If not, what would be the problem?
    My airport is set to join prefered networks by default and the only prefered network listed is the private network on the d-link router.
    I also have a wirless laptop PC and it is able to pick-up and join the network without prompting though it sometimes has a hard time obtaining an IP address.
    Any advice would be appreciated.

    This started to happen to me just recently as well. The iBook was having no problem maintaining the connection with the wireless network. Over the past few days, the connection drops whenever the iBook sleeps or I restart. I have to reenter all the information.
    I don't recall any sort of updates being installed, but it's very confusing.

  • Ibook G4 having  problem with airport connection when using secure network

    Hi,
    I am currently using a brand new Macbook. I am connected wirelessly to a Comcast network through my Netgear Wireless-N 150 router model WNR 1000. The problem I am having is with the 4 year old ibook when I go to use the airport and connect to my existing network it says the password is incorrect. I spent time troubleshooting this with Netgear and basically we found out that the ibook does connect with the network when there is no security at all.
    I erased the hard drive on this ibook to prepare it for sale and it is back to the factory settings. Is there some kind of firmware or drivers I am missing to use the airport as described?? I want to be able to show the buyer that the internet works etc. I also may want to install a few things on the ibook before the sale.
    Thanks a mil

    Did you reset the wireless router to see if by default, it has a different
    wireless security then, than however it presently is set up?
    The question you pose appears to be marked "answered or solved."
    When you reinstall an OS X, the setup asks if you have an existing
    wireless connection, or if you will be getting a new one; by default,
    the setup will make the existing one the automatic one for OS X.
    You should not have to add passwords or other, unless there has
    been one set in KeyChain or for the specific wireless base in question.
    Tiger 10.4.x does not require you to have a set password for wi-fi,
    but you will find several levels of secure options available in OS X.
    Not sure why your setup and configuration is problematic. Usually,
    a totally new OS X installation is without issue. Sometimes, you
    may have to administer a base station via Ethernet cable before
    some configurations can use it, but an existing network should be
    easy, unless it already has a password security in place.
    The Mac will work without a password-protected wi-fi internet source;
    often it will 'just work' even when moved to a new environment and
    a neighbor's network, if not password protected, will appear among
    other options in your vicinity and it will be automatically available.
    Not sure if any newer OS X update parts, from the Combo update
    files to take Tiger 10.4 to 10.4.11, plus others, would help the Mac
    connect better to whatever wireless source of internet available.
    I've not had that issue, as you state, except for when someone has
    a protected network or passwords in place. Mine has passwords to
    keep unauthorized neighbors from easy access; just in case.
    In remote locations where few neighbors exist who could access wi-fi
    from a lone source, no wireless security settings at all, work just fine.
    I've done that; and found a little greater range was gained in signals.
    And in the city (largest town in state) a computer I'd set up for use in
    a password protected wi-fi network - later worked fine and found the
    new owner's own wi-fi network without issues; and I had let the OSX
    setup assistant do its job. If a local network is protected by WEP or
    WPA2, etc with a password, one would be needed to access it. If not,
    then the connection should be automatic.
    Good luck & happy computing!

  • I have a netgear n300 router broadcasting my wpa secured wireless network and bought an airport express to extend the network.  I did an Ethernet setup from a MacBook, got the green checkmark but no extension.  help.

    I have a net gear n300 router transmitting my WPA secured network, and I bought an airport express to use as a network extender.  I configured it  via an Ethernet cable from a MacBook using manual setup in airport utility.  I got the green checkmark at the end, but it is not extending my signal.  Can you help me?

    Unfortunately, most non-AirPort routers are not compatible with Apple's implementation of Wireless Distribution System (WDS)...so it very unlikely that your Netgear router can be extended wirelessly with the AirPort Express Base Station (AX).
    The few non-AirPort routers that are known to work are:
    Linksys WRT54G or WRT54GS (not v5)
    Belkin F5D7230-4 and F5D7231
    BT Voyager 2091
    Netgear WGR614 v6

  • Cannot access my own secure network with G4 iBook

    I set up a WPA secure network with a AirPort Extreme Base Station. No problem using it with my G4 iMac. However, when I try to access it with a second computer, a G4 iBook laptop, using the same WPA password I use to access it with my iMac, I get an error message.
    Using the Setup Assistant with the iBook gives me an "invalid password" message. I know it is the correct password. I set it up and I use it with the iMac!
    When the network is unsecured (no password needed) the iBook can access it, no problem.
    Please tell me what I need to do to be able to access my own secure network with my iBook. TIA!

    The only thing I can think of is the firmware for the AirPort card in the iBook, which is version 9.52. I could not find anywhere in Apple's website how to upgrade this. Does anybody know how to upgrade this firmware?
    If there is any firmware update to the card it is done automagically whenever the corresponding AirPort software update is applied. There is no user notification and no way for the user to make updates diretly.

  • Connecting my Sony BD player to my MacBook Pro wireless network.  It sees the network but it then asks for a WPA security key.  Where do I find this key?

    Connecting my Sony BD player to my MacBook Pro wireless network.  It sees the network but it then asks for a WPA security key.  Where do I find this key?

    Hi Michael,
    It sounds like your router's authentication is set to WPA and thus where the key is established. Does your MacBook Pro connect to a wireless router? If so, that's where you'd need to get the key from via a web-based control panel for the router or if it's an AEBS via AirPort Utility.

  • Setting WPA security on an Airport Extreme Card

    Hi all I’m a newbie to the wonderful world of MACs having just purchased a dual 2.3 G5 incorporating an Airport Extreme card.
    Now, in my simplistic world I figured that I could use the G5 connected to the internet via an ethernet router to act as a base station and allow 2 PC laptops to have wireless internet access too. Also, it would be good to allow these laptops to share the printer connected to the G5 and, absolutely ideally, share files too.
    The internet sharing part of this all this works fine up to a point – that point being until I try to secure the wireless network! I’ve tried using the WEP solution (in both 64 and 128 bit modes) but the laptops just won’t connect, even though they can both actually see the network. I also understand that WPA is more secure than WEP anyway so I thought I might try that instead. Trouble is, I can't find where I can set this up for the AE Card.
    So basically – could anyone tell me, in simple terms, whether I can use just an Airport Extreme CARD (rather than a full Base Station) to give me WPA security in the setup that I’m trying to create?
    It seems that the card itself DOES support WPA if it’s connecting to an already-enabled network, but all I can find in the configuration options for the card is the WEP security (which I can’t get to work AT ALL!) I tried using the Airport Admin Utility to set WPA-Personal mode (which I understand is equivalent to WPA-PSK mode?) but that only seems to be for the Base Station.
    I have spent the last 2 days trawling through as much information as I can find (including on these discussion pages) and still cannot find an answer.
    If anyone’s still reading this rather long post and could offer any help at all, I’d be very grateful indeed.
    Many thanks in advance,
    Andy
    PS I LOVE the MAC!!!

    I need to set the network id to 10.10.1.1 will a new airport extreme do this?
    Sorry, but no.
    The AirPort can only be set to 10.0.x.x, 192.168.x.x or 172.16.x.x

  • IMac G5 Airport Extreme Card WEP/WPA Security connection Problem

    I have an iMac G5 (non Intel) and a wireless Belkin 801.g MIMO router. When I have no security setup on the router (ie straight out of the box)then the Airport Express card connects to the network without problems. As soon as I set either WEP or WPA or WPA2 security on the router and input the correct settings in the Airport configuration in system preferences the card sees the Network but will not connect. I simply get the message "error connecting to network". I have a Windows based laptop with built in wireless card and this has no problems at all connecting to the secured network, whether it is WEP or WPA or WPA2. Does anyone have any thoughts or ideas please?

    I have the same problem with my new black MacBook and a Netgear router. I can connect to the 'free' networks all around me, my Airport Extreme card sees the wi-fi network in my home that I want to connect to, and my old iBook with its lowly Airport card connected (and still does) with no problem using the '40-bit hex' option when entering the password. But now all of a sudden there are just 'errors' when I try to connect (having tried all the various options, and two different types of passwords or keys as provided by the network administrator). Oh yeah, and of course Apple Support won't help because they don't want to know about problems relating to third-party technology... We can't be the only ones with this problem!

  • WPA security with both time capsule and airport express not working together

    I want to set WPA security on my time capsule so that my teenager can not access wireless with out permission but when I add a security key my airport express disappears from list.
    I have tried setting a password then the time capsule restarts and when it does the aiport express is gone from list and can not be found when rescanned.
    Do I need to set time capsule and then reset airport express by pluggin it directly into desktop and resetting its software?
    Thanks

    I would suggest, reconnecting the Express to the TC again. Use the AirPort Utility to make ALL configuration changes including the network extending settings. Then restart both base stations and check that the settings are still good. Then disconnect the Express and give it a few minutes to initialize. It should connect. If not, then the issue may be either the distance or obstructions (like walls, ceilings, floors, etc.) that is preventing the Express from getting a signal from the TC that is adequate enough to extend.

  • HP Deskjet 3050 - Unable to connect to WPA secured wireless network

    Hello,
    My first post here so please excuse any faux pas on my part.  I bought this HP Deskjet 3050 a week ago and have been waging war with it ever since.  I'd be really grateful if someone could possibly advise on how I can resolve this.
    I am unable to connect the printer to my secured wireless network, even though other computers, cell phones, etc. are connected without issue.  I have tried WPA, WPA2 and WPA2-Mixed security modes with the same failure. Specifically, the connection wizard reaches 66% and then displays the error that the wizard is unable to find network/printer.  If I disable the security, the printer connects fine.
    I'm using a Linksys WRVS4400N router with firewall and associated firewall settings disabled.  The router is broadcasting on 802.11G/N mixed mode.
    I'm installing the software supplied on the setup CD on a Windows XP SP3 system.  I have confirmed that the network the PC and printer are connected to are the same.
    A question as well, if I may:  I haven't tried these drivers yet but I see there are updated drivers for the printer dated 14/12/2010.  The release notes indicate improved networking, but don't elaborate beyond this.  Does anyone know if there was a known problem with connecting to secured networks that has now been fixed?
    Finally, just a note that I'm partially sighted and am using a screen reader on all systems.  I'll try my best to be as helpful as I can but please do excuse me if I occasionally can't find settings, etc. on screen and need a bit more detailed help.
    Thanks in advance for your help, which I really will appreciated.
    Have a pleasant day,
    All the best for now and take care,
    Hussein.

    HI,
    firstly, apologies for the delay getting back to you.  Poor health has meant I've had little time nor inclination to do much on the computer side of htings.
    Anyway, I'm please to say the problem with the HP 3050 failing to connect to my network is now solved.  It seems to be a bug with the setup software, and that seems to include the latest version posted Dec 2010.
    To resolve the problem, I did the following:
    1. Disable all security options for the network, so it's just an open network.
    2. Connect the HP 3050 to the network using the setup wizard. This time it connected OK for me.
    3. Locate the printer's IP address.  I used the client list table accessed through my router's interface. You may be able to get this through the printer's on-screen menu, but as I'm partially sighted, this wasn't an option for me.
    4. Log into the printer's control panel at http://ip.address.of.printer e.g. http://192.168.2.108
    5. Under the advanced options, configure the settings for the network, including security protocol and passphrase.  Remember to enter the SSID of the network exactly as configured on the router.
    6. Apply the settings and log out of the printer's control panel.
    7. Log back into the router's control panel and re-apply the security options.  Be sure that they match those match those entered for the printer.
    Hopefully this will be of use to others in the same position.
    Thanks again for your time.
    Best,

  • Airport shows I am connected to a secure network, but Safari will not connect nor will any other internet software.

    I cannot connect via Safari to a live Internet connection.  System preferences show Airport is on and connected to a secure network.  I am able to connect using my iPad and other devices.

    Thanks. Turns out that I had to re list the router and update its password along with resetting the DHCP.  Once that was accomplished all seemed to work fine again.  Just can't figure out why the connection was disrupted.

  • Airport not showing "lock" on wifi after being connected to a secured network

    Our power went down and I had to set-up our router once again....
    I created the secure wifi SSID on the Linksys router....my MacBoo Pro sees the network "with the lock icon" indicating it has been secured properly, I am prompted for the WEP password and upon entering it connect fine to the secured network.
    What is stange is when I look under my wifi connections its shows the SSID that I am connected to but does "NOT" show the lock icon.
    Has anyone else seen this....I have never had this happen before.
    Thanks,
    Derek

    I have had similar problems. I had a time machine malfunction. Went back to Airport Extreme and creted a new network. It works for fine for a while. Then I come back the next day its not working.  Asking for a Apple 80211 Agent. Entered password and won't work. I then started from scratch restting the airport. It works fine. I then create a password WPA2 and it accepts it but I can't lock changes. I also click the need a password to change networks, but it is automatically going to another network. I have deleted that network form my list. Still can't lock the changes.
