Wpa2 key works on 1 out of 3 computers

hello. WRT54GC. 1 vista laptop with built in wifi and 2 desktops with USB wi-fi adapters, xp sp2. maybe 3.
went to IP address and entered router setup. changed to wpa2 and put in password. on the laptop, searched for new wi-fi connections, it found the router, entered the password and everything worked. On the desktops, searched for new wi-fi connections, found router. it asks for the wpa2 key and it doesnt accept it.  will not connect. i go back into router set up, make it an open connection, then i can connect with both desktops. any suggestions. thanks.

If you cannot use WPA2 then use WPA instead. Do not use WEP. WEP is almost as good as no security. It is easily cracked.
On the router, select "WPA2 Mixed Mode" or "WPA2 Personal" and then choose AES+TKIP for encryption. (The exact way depends on your firmware on the router). Then enter a good passphrase.
On the computer select WPA-PSK and enter the same passphrase. See if you can connect now.
If not, select "WPA Personal" on the router with a good passphrase. Same settings on the computer. This should work now.
WPA is much better then WEP. Do not use WEP unless absolutely necessary. If you use WEP you have to enter the first key from the router on the computer. However, with WEP be prepared that someone may be able to hack into your network. Do not have any confidential private information on any computer connected to a wireless router protected only by WEP.

  • NON OF THE F KEYS WORK AS ORIGNAL OUT OF THE BOX DEFAULTS

    I have a Mac Pro 3,1 using OSX6.8.  I have recently replaced the original hard drive for one with larger capacity. In the process, I have made this new HD the startup disk too. All the programs I am using are up to date and are working well. I am having a problem with my Key board function keys though. I regularly use them for sound, the optical disk drive, exposé, spaces, etc. It is really weird opening dashboard with the volume key, hit the f12 key again and my optical drive opens; all with the f12 key.  Another weird issue is when I select spaces with my control key and the designated number the handy spaces window on screen stays in view. The only way I can get rid of that is by deactivating spaces entirely. I have gone through the system preferences and tried to restore my defaults to no avail. Your suggestions are much appreciated.

    In System Preferences > Keyboard uncheck Use all F1, F2, etc. keys as standard function keys.

  • WEP Password Only Works on 2 out of 3 Computers

    I'm having trouble with one of three computers connecting wirelessly to the internet.
    The three computers are MacBookAir, iPad and PowerBook G4.  The first two connect fine.  The PB does not.
    The router is a plain vanilla Linksys WRT54G.  I have it set for WEP Password protection.  The wireless network name appears on all three computers.  I have entered the 10-digit password on each.  The PB keeps returning the not-very-helpful "There was an error" when trying to connect.
    I tried trashing network and internet config prefs.  When running the network assistant on this PB, it says the password is incorrect. 
    I have checked the password multiple times, and it is correct.  I have typed it again, and the same error occurs.
    I also checked the MBA to see if I could see the password, but for whatever reason the "show password" box is grayed out.  I have retyped the correct password, however, and connectivity is still good.  I have no idea how to review the password on the iPad; I just typed it in and it works.  There are no network diagnostic tools available that I can find or any visible place where the number may be verified.
    I have turned off and turned on airport.  I have deleted all network choices in the airport networking settings, shut down and restarted with the same result.  (Airport Status in the network pane has a red dot and says, "Airport is turned on but not connected to a network."
    I'm out of ideas.  Does anyone have a suggestion?
    The PB is a 1.5G G4 running 10.4.11

    First, why use WEP? It's next to useless as an encryption techology which can be broken in less than 15 minutes with commonly available tools on the internet. Use WPA or WPA2 Personal.  All 3 of your systems support both of those.
    That aside, did you try using the Powerbook and WRT54G with no encryption, as a starting point? If that doesn't work, then there's a different non-encryption-related issue. If that works, try WPA or WPA2 Personal. 

  • Sync works on 2 out of 3 computers

    I setup DE so that I can keep my reading in sync on some PDF manuals.  The manuals are stored on a file share.  Setup the first computer, added the manuals to a bookshelf.  Setup the second computer, everything showed up just fine.  Setup third computer, it is as if it was using a completely different account. It does not sync at all.  I've tried uninstalling, removing entries from the registry, the Apps folder and still it won't sync.  I've also tried to Authorize Computer, which comes back just fine with the right account.
    If I can't resolve this, I'll delete DE and go look for something else.  Which would be a shame because the software looks to do exactly what I want.

  • Time Machine doesn't work for one out of four computers

    I have Time Machine running on my Time Capsule and three out of my four computers are backing up reliably. My MacBook Air was away from home for six weeks and on my return TM refused to start. I have deleted the old backup file and set up TM again. I get the usual "Preparing for Backup" message but this persists for ever (at least for 48 hours). A backup file sized at about 250MB is created on the Time Capsule but that is all. During this time there is no evidence of activity and I have finally had to cancel the backup and turn off TM. I've tried everything I can think of but to no avail. Any help would be appreciated.

    I have solved this and thought others might be interested. Last evening I was at the London Mac User Group monthly meeting and raised this problem during the Q&A session. One member asked if I had anti-virus protection installed on the MacBook Air. Indeed I did. I had installed iAntiVirus during my absence from home. So I first tried disabling iAntiVirus and this did not work. I then uninstalled the package and rebooted. Time Machine then sprang into life and is working as advertised. It seems that some (if not all) anti-virus systems can prevent TM from working, but I am not sure why.

    Use the trackpad to scroll, thats what it was designed for. The scroll bars automatically disappear when not being used and will appear if you scroll up or down using the trackpad.
    This is a user-to-user forum and most people will post on here if they have problems. You very rarely get people posting to say there update went smooth. The fact is the vast majority of Mountain Lion users will not be experiencing any major problems with the OS, or maybe with apps which are not compatible, but thats hardly Apple's fault if developers don't update their apps.

  • WRVS4400n & WPA2 not working on Xbox?

    So got an Xbox 360 slim and if I try to connect to route with WPA2 if fails. If I change to WPA or set up a second SSID with WPA it connects and works fine.
    If I connect Xbox to another router with WPA2 it works fine.
    Same results picking AES or TKIP for security type.
    Anyone else have this issue or is this a known problem and can it be fixed?
    The xbox is used in a break room and really don't like the fact that I need to have another ssid and it be less secure, esp as WPA2 has been out long enough this shouldn't be an issue. I test 4 other routers and WPA2 and xbox all work fine but not this one but this is the one I have to use due to feature needs.

    Hi Frank,
    I can confirm this issue as well.  My router is only a few feet from the Xbox, so there's definitely no signal problem.  When I try to connect it prompts me for the key and recognizes that the encryption scheme is WPA2 and says as much on the screen.  I have tried changing the channels (just to be thorough) and changed the key to abcdefghi just to make sure it's not an issue with symbols.  I have rebooted both devices several times and changed every relevant setting I could think of.  It will not associate with the AP.
    It connects fine if I switch to WPA but refuses to connect using WPA2.  I took it to a friend's house and it connected fine to his WPA2 network.  What gives?
    WRVS4400N firmware: 2.0.2.1 (although I tried with 2.0.1.3 first)

  • How to push a WPA2 key to 1600 MB Airs?

    The school system I work with is trying to add the WPA2 key to the Macs without having to go to each computer and manually type it in. We've tried pushing the key with the Default Preferences in the Casper Suite, but so far we've been unsuccessful. Any ideas or suggestions are greatly appreciated.

  • WPA2 key change question

    Hey guys, I am trying to change wpa2 key on an Aironet 1231g access point. Once I change they key, clients cannot authenticate to the access point unless they either change the password or forget and re add the network on the client device. Is there any way to make the client ask for a new key if the key doesn't match when authenticating?

    I believe that GPO will not push out the pre-shared key. It will push out the other settings just not the key. What we have done in the past is use the netsh wlan export command and then create a batch file to perform the netsh wlan import. The batch file and the profile XML can be on a network drive and you can have a login script execute that or have users execute it manually. Of course, I've only done this with windows machines.
    Thanks,

  • When trying to attach my key, the 'Attach My Public Key' option is blanked out so I can't use it.

    This is referring to 'Digitally Signing and Encrypting Messages'. When trying to send my key by email, the 'Attach My Public Key' option is blanked out so I can't use it. I have a work around but it is a bit of a nuisance.
    Any ideas?

  • No key working except cancel key in my Nokia 5200

    sometimes it works nice. but suddenly it goes bad. when except cancel key no other key works. at that time i can only reject calls from other or switch off or on. what should i do? but after some time may be some hours it will act ok. whats the problem?

    If the phone isn't responding to anything, I don't think you have much choice other than taking the battery out.  I've had to do that on previous phones (not on my E72 yet, knock wood), and it has never caused problems.

  • Foreing keys works only when created as CAPITAL?

    Hello,
    When working with HTML DB tutorial, I have noticed that foreign keys works only when I do create them as CAPITAL. I did create some foreign keys manually, and when I was trying "query by example" it did not work correctly unles I did re-create the foreign keys using all captials in their name. Why is it that?
    Thank you,
    DanielD

    I let it dry out more and it started working. It still has a quirk or two but I can live with it.
