Why do I need to reconnect after sleep with WEP enabled?

I have a MacBook and an old iMac. I enabled WEP and closed network on my Snow Airport but now every time the iMac goes to sleep and wakes up, I have to reenter the WEP key to connect to the Airport. This does not seem to be a problem on the MacBook. I put the iMac in my 5 year old son's room so he is too little to reenter the password everytime, that means I have to do it. That just doesn't seem right. Shouldn't the password remain active and logged in to the Airport even through sleep? Is there another setting I have to change? For now, I just disabled WEP but I am concerned about the lack of security. Thanks for any help or advice.
Oh, I configured the AirPort on the iMac because I could not get the AirPort Admin Utility to work on my MacBook. I just read a previous post and found the solution to that but have not tried configuring the Airport from the MacBook to see if that makes a difference. Need to go to work now. Thanks for any advice

Try the following on the iMac, if you use Preferred Networks:
1. Delete Preferred Network(s)
o System Preferences > Network > AirPort > Configure
o In the "By default, join:" pull-down menu, select "Preferred networks"
o Delete the network(s) you regularly use from the list
2. Delete AirPort Keychain Entries
o Launch the "Keychain Access" application located in Applications/Utilties.
o Click on the "Kind" filter at the top, and look for any "AirPort network password" entries...and delete them.
o Restart, or log out then back in.
3. Add Preferred Network(s)
o System Preferences > Network > AirPort > Configure
o In the "By default, join:" pull-down menu, select "Preferred networks"
o Add the preferred network(s) using the "+" button.
o Restart or log out then back in.

  • Windows 7 brightness reverts back, wifi takes long to reconnect after sleep

    Hi fellow members,
    My brightness setting keeps reverting to max. I have tried setting via power manager and also from control panel.I can adjust but when the computer restarts, the brightnes reverts to max. It started happeing around a month ago. I didn't have these issues until about 2 months ago. I have had my x301 for over an year without issues.
    Another issue I have been experiencing is that wifi takes a long time to reconnect after sleep. About 5 minutes. This is also a new issue.
    I have the latest BIOS, latest power manager, all drivers are upto date. Here are the specs.

    Check in the Windows power profile for the brightness issue. Windows will apply it's own at boot, then Power Manager will override, which leads to a momentary discrepancy.

  • Why will macbook pro not go to sleep with Lion OS?

    Why will macbook pro not go to sleep with Lion OS?

    Test after each of the following steps that you haven’t already tried:
    Step 1
     ▹ System Preferences ▹ Energy Saver ▹ Power Adapter ▹ Wake for network access: uncheck. You may need to unlock the preference pane by clicking the lock icon in the lower left corner and entering your administrator password.
    Step 2
     ▹ System Preferences ▹ Energy Saver ▹ Schedule… ▹ Start up or wake: uncheck
    Step 3
     ▹ System Preferences ▹ Print & Scan ▹ Open Print Queue...
    Check all printers for unfinished jobs. Deal with any you find.
    Step 4
    Disconnect all wired peripherals except keyboard, mouse or trackball, and monitor, if applicable.
    Step 5
    Launch the Activity Monitor application in any of the following ways:
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
    ☞ If you’re running Mac OS X 10.7 or later, open LaunchPad. Click Utilities, then Activity Monitor in the page that opens.
    Select All Processes from the menu in the toolbar, if not already selected. Enter “powerd” (without the quotes) in the "Filter" text field. Select the powerd process and click the Quit Process button in the toobar (stop-sign icon.) In the sheet that opens, click Force Quit. You’ll be prompted for your administrator password. The process will be relaunched immediately.
    Step 6
    Boot in safe mode and log in. The instructions provided by Apple are as follows:
    Be sure your Mac is shut down.
    Press the power button.
    Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
    Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
    The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
    Note: If FileVault is enabled under Mac OS X 10.7 or later, you can’t boot in safe mode.
    Safe mode is much slower to boot and run than normal. Don’t launch any applications at first. If sleep still doesn’t work properly, back up all data and reinstall the Mac OS. After that, if you still have the issue, make a “Genius” appointment at an Apple Store to have the machine tested.
    If sleep now works as expected, go on to the next step.
    Step 7
    Still in safe mode, launch the usual set of applications that are running when you have the problem, including your login items, one at a time, testing after each one. Some applications may not work; skip them. You might be able to identify the cause of the problem this way.
    Step 8
    If sleep is still working after you’ve launched all the usual applications, reboot as usual (not in safe mode) and test again. If sleep still works, you’re done, at least for the moment.
    If you still have the sleep issue after booting out of safe mode, post again.

    Why is atv slow to buffer after connecting with cat5 cable

    As I am not sure the cause, I have been reading and trying different things, last thing was to set the interfaces to Duplex Full

  • How much time ipod needs to restore after plugging with external power?

    how much time ipod needs to restore after plugging with external power?

    Restore? Do you mean power on after it's been drained for awhile? It depends how long it's been dead. Sometimes it can take awhile (10-20 minutes maybe more) in some cases.

  • Why do you need an f after a float initializtion?

    When you make a declaration and initialization of a float, you have to put an f after the number, correct?
    Like
    float productPrice1 = 285.00f;
    why do you need to do this and do you need to do it in an assignment operation to?
    productPrice1 = 285.00f;
    What about for doubles? Would I need to use a d in place of the f?
    thanks

    What about for doubles? Would I need to use a d inplace of the f?
    No, you need to do that to tell the compiler it is a
    float, not a double. When assign to a double, you
    don't need to tell the compiler it is a double. :)although nothing bad will happen if you do use a 'd' or 'D'.
    Good luck in learning Java.

  • Slow reconnect after sleep

    My early 2006 iMac takes a long time to reconnect to my wireless network after sleeping. It finds the network no problem just takes up to a minute to "wake up" and find and join the network. Is there any way to speed up this process? My Macbook connects about ten times faster after coming out of sleep so it has to be something with the iMac and not the network.
    Thanks for any help.

  • Solution for 'my mac will not reconnect after sleep'

    After lots of trial and errors I found the way around the problem of dropped or very poor wireless connection after you put your mac to sleep.
    I have no idea what the problem really is but this procedure has stopped me from throwing my brand new MacBook through the window.
    1) Go to System Preferences -> Network -> Advanced
    2) Remove any network you have there memorized
    3) uncheck option 'Remember any network this computer has joined' (leave the other options also unchecked)
    4) press ok and switch AirPort off ... then on (make sure you have 'Show AirPort status in menu bar' checked)
    Now the only real change we've made is to stop Mac memorizing our network - but here lies the solution.
    Put your MacBook to sleep and than wake it up. It will not connect to the network (none are memorized) but all you have to do is choose your network name from the list on the menu bar. It might ask you for the key but in my case it simply asks for permission to use my KeyChain (memorized WPA2 password).
    Once I press 'Allow' .... it works as it should! eureka!
    Do not check 'Remember this network' when asked for password.
    As long as Mac does not store your network details it reconnects without problems, once you allow it to store these details, re-connection after sleep goes pear-shape.... figure it out Apple!
    I hope this might help you (as it most certainly works for me)
    best regards
    ffar

    I've run Keychain utility. I also removed (as suggested in various places) any entries referring to my wireless password in KeyChain and allowed them to be memorized again. It doesn't change a thing.
    Please understand me correctly. My Airport does re-establish connection automatically (if network details are stored) but connection is extremely flaky, slow and with frequent dropouts. So the Keychain is not to blame here (I think).
    If I establish connection 'semi-manually', as described in my previous post, it is perfect, just as it should be. This would indicate to me that the problem lies not with the Keychain, but in the way OS stores network details.
    If I do not allow OS to keep network details - re-connection works.

  • Wireless network does not automatically reconnect after sleep

    I have a Belkin wireless G+ mimo modem router network. When I wake the mac from sleep it does not automatically reconnect to my wireless network and i have to manually select the network from the airport icon in the menu bar and then it connects without having to reenter my secure password. How do i set the mac to auto connect to the network after sleep? There are about 6 other wireless networks in range which may be effecting this reconnection.

    In may case the network was already at the top of the preferred networks list.
    Based of of a hint over at MacOSXhints.com, here's how I fixed this problem:
    1. In the Network references pane, delete the Airport connection that does not like to reconnect.
    2. Click Apply and Quit the System Prefs app.
    3. Put the computer to sleep.
    4. Wake the computer.
    5. Go back in to the Network pref pane and re-add the Airport connection. Do not try to connect to the network at this time.
    6. Click Apply and Quit the System Prefs app.
    7. Use the Airport menubar app to connect to your network.
    8. Verify connectivity
    9. Put the computer to sleep.
    10. Wake the computer.
    11. Verify connectivity
    My machine now consistently reconnects when coming out of sleep or restarting.
    God luck!

  • How to make trackpad automatically reconnect after sleep?

    I have a magic trackpad and an MB Pro.
    When I return to the computer after it has been sleeping overnight, the magic trackpad will not reconnect automatically.  If the computer sleeps briefly, the connection is restored automatically.  If the trackpad is powered off after sleep, it will reconnect when powered on.  But after a long sleep, or perhaps when I have disconnected the laptop for a while I cannot easily make it reconnect.
    It will not reconnect if: I click the power button, click the trackpad, select the trackpad by name and connect from the bluetooth menubar item, connect manually through bluetooth preferences, or turn off the trackpad entirely then turn it on again (force into discovery mode). 
    The only somewhat reliable way I have found to reconnect is: 1) turn off trackpad power, 2) go to trackpad preferences, 3) set up bluetooth device, 4) power on trackpad, 5) select continue when device is found.
    When disconnected, in bluetooth preferences, the device is shown as being paired.  I added it to Favorites.  It is discoverable.  Battery power is good.
    I can reproduce the same symptoms with these steps: 1) put the computer to sleep, 2) manually turn off the trackpad, 3) turn on the trackpad again (it blinks, indicating attempt to discover), 4) wake the computer.
    Can anyone help me find a less time-consuming way to re-establish a connection when the computer wakes from sleep?
    Thanks,
    Tom

    Hi Jeff,
    Thanks for the suggestion. I tried the 'root bridge' in Access Point mode but the remote devices did not try to reconnect. I also tried 'non-root bridge', 'root bridge with network clients', 'automatic' etc. I let it sit for a few minutes after each change to see if it helped.
    I've going to change it to 'Access Point' again and leave it overnight to see if one of the three remote Workgroup Bridges that are currently unavailable will re-connect.
    I know if I ask the site electricians to power the remote Workgroupd Bridges off and on they will connect for a while - its quite frustrating!
    Thanks again

  • No display after sleep with macmini using DVI - S-video/composite under XP

    Hi guys, I have installed XP on my mini. I have CRT TV so I'm using
    DVI -> S-video/composite to output to my TV.
    The problem is after sleep - there is no display (it's woking only after reset).
    I installed the latest drivers from the mac os 10.5 DVD & updated the graphics driver from Intel.
    Please help

    Unfortunately, no answer, as I'm having the similar problem with a Samsung SyncMaster 215tw and a G4 Mini. It works with the DVI-VGA adapter and the VGA cable into the montor's VGA port. However, connecting with the G$ Mini's DVI port with the monitor's DVI port using a DVI cable doesn't work. I cannot figure out why this doesn't work.
    The DVI cable is good and the monitor's DVI port is good, as the connection does work using my friend's Intel Mini's DVI port connected to the monitor's DVI port using the DVI cable.
    The monitor is new, too, and otherwise works fine with my other Macs connected with the VGA port. (I've not tried the additional ports as yet.)
    Although the monitor is supposed to synchroize automatically, I also tried manually presetting the G4 Mini to different resolutions, but that didn't make any difference. The screen remains black when it should be showing the booting Apple icon.
    Any idea what is going wrong here, please, as it sounds as if this same thing occurs with various monitors?

  • Why did my MBP just "awake from sleep" with a greyed-out beach picture????

    My MacBook Pro just awoke from sleep with a greyed-out image of a beach scene while a status bar at the bottom of page appeared to show some form of check-up or update.
    Any idea what this was?

    I think that's what the MBP does after the sudden motion sensor detects alot of movement. I'm not 100% sure, though.

  • WiFi must manually reconnect after sleep (since updating to 10.9.4)

    My MacBook Air (Mid 2011) just updated to 10.9.4 and now the WiFi doesn't reconnect to my home network when I resume from sleep (open the lid). I need to click the WiFi icon and re-choose the home network each time.
    This is new since I updated. Ironically, when I read the update notes, it was supposedly to fix this type of issue from occurring in the first place, and yet I never had the problem until after I updated.
