Airport won't connect with WEP active

I have a Netgear router (the one Sky issue that everyone seems to have) and my Mac Mini refuses to connect to it when I enable WEP security, even when I select 'Other' from the Airport menu and input the WEP key.
I have to turn off WEP to be able to go online on my Mac. Is there a way to fix this?

You might try resetting your connection settings using the steps listed in this message:

They're not guaranteed to solve the problem, but they'll only take a minute or so to try.
2. what are the possible consequences of keeping it unsecured?
If there are any neighbors near enough to connect to your network, you could have trouble from them sharing your bandwidth or worse.

    I just installed Airport Extreme. It works as a wireless network on my Macbook. It won't connect with my Windows Visa PC. Message reads: "settings saved on this computer for the network don't match requirements of the network." I seem to need to enter a security key/passphrase to connect to the PC. Where do I find them?
    Thanks for your help.

    I assume that you have Wireless Security enabled on your AirPort's wireless network. The issue maybe that the PC is unable to use the WPA password itself and will require using the Equivalent Network Password instead.
    To get this password, you will use the AirPort Utility from the MacBook:
    Start the AirPort Utility > Select the AirPort base station > Manual Setup
    Now, before doing anything else, go up to the utility's menu bar at the top of the screen, and then, choose "Base Station," and then, Equivalent Network Password from the drop-down menu. You will see two items: 1) WPA Password, which should look familiar to you, and 2) WPA Pre-Shared Key. It should be a long hexidecimal set of numbers and letters. Jot down this second item.
    You will want to use the value you just jotted down when entering the password from the Windows Visa PC.

  • Tried to update to newest version. I got error because i didn't have this recovery program disc that was supposed to come with the purchase but it didn't and now my ipod touch 8gb won't connect with itunes and is stuck on a connection with itunes screen

    I tried to update to newest version via pc. I got error because i didn't have this recovery program disc that was supposed to come with the purchase so it says, but it didn't and now my ipod touch 8gb won't connect with itunes anymore and is stuck on a screen displaying an itunes icon with a usb icon.

    oke i'm not done with the whole thing, but i'm doing that right now. Most of the advice I've already read didn't work and at a certain point it said something about shutting down programs then restart. but i notice that there are some pretty important system things in that list and i don't want to mess up my pc :s i'm not a pc genius... and because i'm dutch and my pc-language is in dutch I often have trouble translating and well... i don't always understand the technical stuff in all the articles -_-

  • I have a toshiba lap top computer with vista and I can not get my iphone to connect all the way .. it says "connected with limited activity"?

    I have a toshiba lap top computer with vista and I can not get my new iphone to connect all the way .... it says "connected with limited activity". which means I don't get on. Any help would be appreciated. Thanks.  

    Hi all,
    Guess I understand what is going on as I'm also experiencing the problem.
    Basically the issue is about the iPhone 4's personal hotspot.
    I'm trying to hook on personal hotspot to my toshiba laptop but it couldnt work as the connection is limited to local only without Internet access.
    The hotspot works well on other laptop and I-devices, but not my toshiba...
    Hope to get assistance here. Thanks

  • After lion 10.7.3 update messed my mac had to restore from time machine now Outlook won't connect with microsoft exchange, any idea?

    after lion 10.7.3 update messed my mac had to restore from time machine now Outlook won't connect with microsoft exchange, any idea?

    I've had a similar problem.  On my first boot up after installing 10.7.4,  Firefox would not open.  Crashed every time.  Safari was not affected.  I have no idea if it was related to the flash plugin, but I did install a the latest version of that a couple of weeks ago. 
    Here's what fixed it: a second boot up.

  • Deskjet Advantage 3540 (Envy 4500): Computer won't connect with printer during software installation

    I just bought this printer and I am trying to install it by using the HP installation CD but I am running into difficulties to complete the process. The problem is that the computer won't connect with the printer (but my printer connects fine with my Wi-Fi network) and installation does not complete.
    The HP software installation process appears to go  normally (at least no error messages are shown) but when it gets to the part where it asks me how I would like to connect to the printer (Wireless or USB cable) I get an error message when I select Wireless Mode. My printer appears listed but as soon as I select it, a dialog is shown stating that "network installation could not be performed".
    Below are the dialogs and what happens (text is in portuguese but you get the idea)
    Dialog 1: selecting wireless connection mode
    Dialog 2: printer appears in list and I select it
    Dialog 3: Error message is shown, no further details
    Here are some more facts:
    (1) Printer connect fines with my Wi-Fi network: the connection details are correctly shown in its display (Wi-Fi SSID and IP 192.168.0.6) ;
    (2) If I go to a web browser in my computer and type in the IP address, I can access the printer's webpage fine;
    (3) I've tried uninstalling and reinstalling HP software;
    (4) I've resetted my router;
    (5) I've executed "HP Print and Scan Doctor" utility and it states my software hasn't been installed (which I don't understand) and it tries to download HP software and install one more time and I get to the error.
    (6) If I go to "Start" menu, I can see the HP group is empty (installation only creates icons on my desktop). See picture below:
    My OS is Windows 7 64 bit Ultimate (Service Pack 1)
    EDIT: I've just discovered the inkjet Advantage 3540 and Envy 4500 appear to be the same printer, each target to a different market.
    Help is much appreciated as I tried a lot of things to make this printer work wirelessly with my computer but without success.
    Thank you,

    Microsoft Exchange won't connect with my iPhone (it's saying the password is incorrect, but it shouldn't be), now I can't delete that inbox on the phone.  Help??

    Turn off wifi.  Use wireless signal. reenter password at settings.  This should work.  Turn wifi back on if you wish.  Wait for next occurrence within hours or days.  Have not found a permanent preventive solution.  Thinking of replacing my four year old wireless router.

  • My iPhone won't connect with my computer or charge. How can I fix this?

    My iPhone won't connect with my computer. It also will not charge. I changed the white charging cord, but I have the same problem. I connected other devices to the USB and they work. It's strictly the iPhone.
    How can I correct this?

    I forgot to mention, the iPhone does charge via wall plug.

  • IMac 10.5.8 ... Time machine died. Bought new Time Capsule2TB. Ordered 10.6 ... Not recommended to install 10.6 w/o prebackup ... Current utility for airport won't do with the new Time Capsule. ... What to do?

    You are in the typical catch22.. you cannot use the TC without setting it up.. you cannot set it up without Lion.. so you can install the latest utility.
    Do you have any reasonably current iOS devices.. they can run the iOS version of the utility.. that will allow you to set up the TC.
    Or invite a friend with a laptop running at least Lion
    Or take the TC back and get a plain USB hard drive and backup to that.

  • WEP Connection iBook Won't Connect if Password Active

    Just got a new iBook today.
    Currently running a Linksys Router (802.11b) with WEP. My G5 is direct connected to it.
    When I activate my WEP password my iBook will not connect.
    I've tried creating/entering a variety of passwords. (Exactly 13 character) As demonstrated in this document:
    http://docs.info.apple.com/article.html?artnum=108058
    If I disable the WEP I connect without a problem. I'd like to have some password protection.
    Does anyone have any suggestions what the problem could be?
    thanks.
    --Kevin

    ]I just moved into a household w/ a linksys WEP router. Everyone in the house uses PC except for me. I have an ibook. My airport can detect the network. However, when I tried to join the network by using the WEP key as the password, it didn't work. Is a WEP key different from a WEP password? I talked to the linksys tech support people but they knew nothing about apple so they told me to ask the apple people.
    One of the problems with WEP is that the actual standard relies on a 10 character HEX key for 40bit WEP and a 26 character HEX key for 128bit WEP.
    In order to make things easier for people, vendors use certain algorithms to convert simple alphanumeric passwords (or passphrases) into HEX keys, thus enabling people to use simple memorable WEP password rather than lengthy HEX keys.
    The problem is that different vendors use different algorithms to generate the HEX key and therefore a ASCII password on an AEBS will be hashed differently on a Netgear client and vice versa.
    One thing is a 13 character 128 bit WEP password will be hashed by all vendors in the same way (if you use 40bit WEP then a 5 character password is required).
    Though sometimes not even that works and the HEX key must be used regardless.

  • Regaining Airport connection with WEP and Siemens Gigaset

    After loosing connection with MBP and Macbook and latest security- and Airport updates, reinstalling of IO80211Family.kext vers.1.5.1 helped.
    It's included in Airport Extreme Update 2007 001.
    Extracted it with Pacifist and copied it the Extensions folder.(as root)
    Important!!
    Repairing permissions and reboot.
    Took me two days to find out.
    Maybe it helps for other third party routers too.
    Intel MacMini works with all latest updated. (so far)

    Can anyone talk me though what to do since I know very little about wireless networking. I am quite prepared to buy a new wireless adaptor for the PC, but don't want to buy something that isn't going to work.
    Unfortunately, you didn't provide much information about your PC or the current external wireless adapter to be of much help. WPA was first supported with WinXP w/SP1; which OS is your PC running? Likewise, early versions of wireless adapters only supported WEP. What is the make/model of yours? Does your PC support PC cards, PCI cards (internal), and/or USB devices?

  • Airport Extreme won't connect with my cable modem (Time Warner)

    OK, I'm tired of staring at a blinking amber light. I'm reaching out to anyone out there who's had this problem. I've got everything connected right, the software loaded, the connections set on my laptop (Macbok Pro). But still my Airport Extreme won't connect to the Internet. I've tried different cables, rebooting both my modem and my Airport. For the record, I've had a Mac IT guy from my advertising agency come by my house and make sure that everything's installed and hooked up right. But it still keeps saying that my IP address is invalid, even though I can connect (wired) using the modem.
    I suspect I'll just have to take it to the Genius Bar or something. But anybody got any ideas? I really want to join the 'n' generation....

    atotheb, Welcome to the discussion area!
    Did you power off the cable modem when switching the Ethernet connection from laptop to AirPort Extreme base station (AEBS)? This is usually required.

  • "Incompatible Security" when trying to connect with WEP password

    I just bought my MacBook and so far AirPort has been working with all wireless connections I've used. I recently moved into a new apartment with wireless internet. The gals here are using a Motorola router connected to a Windows XP desktop.
    Why is it that everytime I connect using the correct WEP password/configuration, it says "Incompatible Security"? I've tried everything with network preferences and the like. Why is it that the Macbook won't connect to this wireless router but will connect to others...?
