Wireless Connection Lost in Sleep Mode

I connect to the Internet via an Airport Extreme Base Station and a Toshiba cable modem. It worked fine since I bought it in February, but in the past couple of days, my Powerbook loses the connection with the Airport whenever it goes into Sleep Mode and I have to go back into System Preferences and reselect the Base Station to regain it.
I've tried resetting the Airport preferences and turning off the computer to reboot. I've also reset the Base Station itself.
Any suggestions?

Let's see. So you bought 250mb data and ran thru it, then purchased unlimited.
People seem to not understand a few things. First, 250mb of data is nothing. If you are not a "techie type" perhaps you should have researched exactly what you can do with 250mb. Ten images from my Nikon are OVER 250mb. Second, you paid 15 bucks for 250mb data and as I said, ran thru it. You got your 15$ worth of data. What do you want refunded??
Third, then instead of waiting until your month was up and you got another allotment of 250mb you didn't want to wait and chose to go on the unlimited plan. That plan started that day and will last for 30 days. What exactly do you feel should be refunded? The 250 you used, or the unlimited which you plan to use?
So to recap:
1. You have no idea how much data you can stream for 250mb.
2. You paid for 250mb data and used 250mb data.
3. You then paid for unlimited data, which is your current situation.
4. You then called Apple (which has nothing to do with AT&T billing) and are now mad because no other cell phone provider has the micro sim AND come here to trash the "techie type" who honestly answered your question.

Wi-Fi Connection lost in sleep mode

After upgrading to 3.0, my Wi-Fi connection is lost as soon the iPhone gets into sleeping mode. After unlocking the connection doesn't wake up. New Bug?

there's now an option to Auto-Join each specific network. It might default to no for your wifi network. Just clock on the blue arrow next to the network name and tell it to Auto-Join.

Connection lost after sleep mode

When my computer comes out of sleep mode, it's not connecting to the Airport wireless connection. Waiting doesn't seeme to matter...the icon on my iMac (upper right on screen) shows no connection. I have to manually turn off Airport and turn it back on to get it to connect (turning it off and on using the icon).
I have made zero changes to my system, other than that we moved to a new home. No equipment changes...no settings changes. What the heck is going on to cause it to no longer connect when coming out of sleep mode? And more importantly, how do I fix that? Thanks very much!

Try the following, in order, until (hopefully) resolved:
1a. Delete Preferred Network(s)
System Preferences > Network > AirPort > Advanced > AirPort tab
Under "Preferred Networks," delete the network(s) you regularly use from the list.
1b. Delete AirPort Keychain Entries
Launch the "Keychain Access" application located in Applications/Utilties.
Click on the "Kind" filter at the top, and look for any "AirPort network password" entries...and delete them.
1c. Add Preferred Network(s)
System Preferences > Network > AirPort > Advanced > AirPort tab
Add the preferred network(s) using the "+" button.
Restart or log out then back in.
2. Move System Configuration Files
(Note: You will have to reestablish your network connections settings.)
Go to /Library/Preferences
Move the SystemConfiguration folder to the desktop.
Restart your Mac. (Note: OS X will rebuild the files that are now sitting on your desktop. If this doesn't resolve the issue, you can move the folder back to it's original location.)

Wireless Connection lost after sleep: iMac 27-inch

When my iMac goes into sleep mode, or logs off after pre-determined time, it loses the wireless connection to the router. I then have to go to the upper right of the screen, select my router from the list of available routers, and force a connection.
Has anybody else experienced the inability to maintain persistent wireless connections?
Thanks!

I had the same problem for weeks with my new 27" iMac. I tried resetting p-ram, adjusting network settings, throwing out preferences for network settings - - - everything! Nothing worked. I final called Apple support and they told me to unplug EVERYTHING from the Mac, including power, wait 30 seconds, and reboot.
Works fine now.
Hope that helps!

Internet connection lost in sleep mode

My internet connection dies when going into sleep mode. What can i do to fix this?

+My internet connection dies when going into sleep mode. What can i do to fix this?+
It's not broken. Don't put your computer to sleep manually and do change your Sleep settings on the Energy Saver pane of System Preferences. Your entire system can operate without interuption when "Put the display to sleep" is activated, so that time can be shortened while you lengthen the amount of time the computer will be awake to something more convenient - or set it to "never."

Bluetooth connection lost after sleep mode

I'm using a bluetooth keyboard with my iPhone. It works great. However, if the phone goes into sleep mode, it does not keep the connection and I have to re-establish the connection through settings each time. Is there a way to keep the connection or have it automaticaly reconnect?

I use the Apple bluetooth. When I sleep my iPad it actually puts the keyboard to sleep. Probably to save the batteries. When I wake the iPad, I still have to go to the Bluetooth and reconnect via the iPad. The keyboard automatically turns back on so I don't have to power it on. I think that is the best you could hope for.

Airport connection lost after sleep mode

Hello everbody,
Each time I send my PowerMac G4 MDD Dual 867 to sleep it won't to connect to my (or rather to any) Airport network anymore after waking up, it just seems as if Airport is completely defunct after waking up.
My iBook G4 works without any problems on the same network, by the way.
I know the workaround with restarting IPv4 networking (described here: http://discussions.apple.com/thread.jspa?messageID=1122310&#1122310) and I have also created an AppleScript for automatising this process, however I am still wondering, if this issue will ever be addressed by Apple, since it is still present for me in 10.4.6.
Best regards,
Björn Wilmsmann
PowerMac G4 MDD Dual 867 with standard Airport card Mac OS X (10.4.6)

Okay, this might not solve your problem, but I had a similar problem when I switched from WPA2 to WEP on my Airport, therefore also changing the password which again somehow got my Powerbook confused.
I went into System Preferences > Network > Airport and looked at my "Preferred Networks" list (Not "By default, join..." > "Automatic"). Then I edited my airport network in that list (the small "Edit" button) and I saw that the password somehow was corrupted. When I corrected this error my Powerbook began joining automatically after sleeping again. Strangely, this setting has nothing to do with the Keychain Access, even though you can find your base station's password there too...
Oh, and I might add: My airport is on a closed network and is therefore not "visible"...

My macbook pro 2.0 early 2011 will not go to sleep with the power source connected. only enters sleep mode when running on battery. Someone did this happen, and it could solve?

Alo, my Macbook pro i7 2 GHz Intel Core i7 (early 2011) will not go to sleep with the power source connected. only enters sleep mode when running on battery. Someone did this happen, and it could solve?

There is no output from that command line? Maybe the pid changed.
I'll repeat what I am trying to find out...
1. You do a pmset -g on the terminal.
2. The output from that pmset should have a line that says "sleep 0 (imposed by n)" where n is some number.
3. The ps ax | grep n is supposed to display what the process associated with n is.
It's the output from step 3 that should indicate what is causing you not to sleep.
But speaking of sleep, that's where I am going.

BEFW11S4 wireless connection lost after reboot / sleeping

I am using the linksys wireless router BEFW11S4 version 4, firmware version 1.5, to connnect two winXP computers, one a desktop (wired) and one a laptop (wireless).
The wireless connection was created using the EasyLink Advisor software (support.linksys.com). The wireless connection made by this software to my laptop has no signal strength problems. A wired connection to my laptop also has no problems.
However, if a wireless connection is made, it is broken when my laptop is restarted or sleeps (power saving mode). The sysTray indicates a wireless connection that has "limited or no connectivity". I cannot browse the internet. The EasyLink advisor automatically detects a problem and prompts ot repair it. Though after a few steps the EasyLink Advisor indicates that a "wireless connection failed to be made", the sysTray shows a healthy connection, and it becomes possible to browse at this point.
I'm hoping to make a connection that doesn't need to be re-established every time I leave my computer. Has anyone experienced a similar problem?

Carrot, thanks very much for your message. I tried updating the "firmware" -- is that what you meant by drivers?
By following the instructions at http://linksys.custhelp.com/cgi-bin/linksys.cfg/php/enduser/std_adp.php?p_faqid=4030&lid=7771778881B05,
I upgraded the firmware which involved performing a factory reset on the router, and re-establishing the network using the EasyLink Advisor.
All of the steps were carried out easily according to the instructions and there were no hitches or exceptions. The wireless connection made was strong and usable. At this time I added my second (desktop) computer which has a wired connection, by following the "add another computer" wizard in EasyLink Advisor.
This completed the re-setup of my network with new firmware.
I then restarted my wireless laptop, and, unfortunately, the connection was lost, as usual.
any other suggestions?
Thanks again!

Wireless connection lost upon wake from sleep

I recently joined the 21st century and purchased broadband internet for my home. I am connecting via wireless ethernet using an original Airport card and flying-saucer type base station. All I did was connect the base station to the cable modem with an ethernet cable, plug it in, and restart my eMac. The network showed up right away and I was connected. Unfortunately, after my Mac went to sleep and I woke it up, not only was there not a connection, but there was no sign of the network.
Airport status showed it was still on, but in the spot where the networks show there was nothing. Restarting corrected the problem, but I assume only until it sleeps again. I can change the settings to make it monitor-only sleep, but I would like a more permanent solution.
What might help to fix the problem, and was there something I needed to do besides just turn my machine off and on to set up this network?
Thanks.

If you pose this problem over in the Airport or Tiger networking forums, you'll find you've stumbled into a morass of conflicting reports. There have been a disturbing number of reports of Airport connections lost in Tiger after wake from system sleep, usually not reconnected until after a restart. Some people have some success checking the box to put the Airport icon in the menubar ans using that to turn Airport off, wait a few minutes, and turn it back on, yet others have reported that only works part of the time and others report it doesn't work at all. Some have reported improvement after downloading and running the full OS X Update Combo 10.4.10 (PPC) on top of an OS updated via Software Update. And the large majority of Airport users never report any problems at all using Tiger. It really sounds like there's no one cause and no one fix.
There is a workaround: don't let the Mac go into system sleep. Use the Energy Saver system preference to set system sleep to Never, uncheck the 'put hard drives to sleep when possible' box, and set the display-only sleep to say 20 minutes. If the eMac is in a bedroom and the sleepers are sensitive to fan noise or power LED lights, that will be a problem, but likely less aggravating than losing your broadband connection.

Wireless connection lost after awakened from sleep.

I have the 2 month old 17" 2.16Ghz Macbook Pro Core Duo. Whenever I put the unit to sleep the wireless connection is lost when awakened. The Airport preferences pane shows a full strength signal and a base station ID but I cannot load a webpage, get or send emails, and ftp connections are broken. If I plug in an ethernet cable All is well again.
The ony way to restore the wireless connection is to either restart OR logout and log back in.
Any suggestions?
THANKS

Do this.
Open network preference panel
Select Airport on Show: drop-down menu
Select Airport tab
Select Peferred networks as the Join by default: item
Delete your network
Close preference panel
Reopen Network panel
Return to Join by default: and add your network
Press Apply now.
That should do it

Wireless connection lost after macbook pro sleeps for more than 15 minutes

It's annoying. I have a brand new macbookpro 3.06Ghz 17" hi-res screen running OS-X 10.6.3 and the wireless connection keeps dropping after the computer is either turned off or sleeping for more than 15 minutes.
My router is a linksys wireless G, has dd-wrt software in it which is very powerful. When I release or renew the DHCP at the router, the mackbook connects to the wireless network, no problem.
What configuration can be done at the macbook as to not have it time-out airport wireless connections unless I renew/release DHCP at the router? This is an annoyance beyond the limits of anyone's patience.... Thanks in advance for any help!

Well, since nobody answered this post I decided to try a bunch of things and I believe I came to a solution:
1 - Make airport the first connection under System Preferences->Network
2 - In the advanced window:
- Under AirPort: Keep only one network name on the list (the one you use all the time)
- Select 'remember networks this computer has joined' and deselect all other boxes
- Take note of the Airport ID (xx:xx:xx:xx:xx) and put it in your router's MAC address list. I do this because I only allow connections to my router from mac IDs that are on the list I create. In my case, I have my macbook pro and my PS3 system. If you don't know how to edit the MAC list in your router, do some research. It's pretty easy.
- Under TCP/IP: Select "Using DHCP" on the IPv4 drop box
- Select "Off" for IPV6 drop box
- Under DNS, after you connect at least once, you should see (grayed out) your router's IP address on the left box and the domain on the right side box.
Finally, under "Ethernet" you should see your Mac address there, the configure option should be set to Automatically and MTU as standard (1500).
Press OK and then press "Apply" and lock that screen by clicking on the padlock at the bottom left. BTW on the top of this screen Location should be "Automatic" - if not, select it and apply.
Done! Your wireless should connect quickly after the computer is turned on or waken up from sleep state. This assumes you configured your router correctly (mac addresses, frequencies, etc).
Good Luck to all who try this - at least I have not have any more dropped wireless connections.

Lost Bluetooth Connection when in Sleep-Mode

Hey,
when i have three devices hooked up with bluetooth to my 2009 27" imac (keyboard, magic mouse, magic trackpad) it randomly looses its bluetotth connection.
so i have no possibility to type my password to log in.
it mostly happens when the mac is in sleep-mode for longer period of time like over night or so.
i have to restart the system with on/off-button which realy ***** ...
does somebody have the same probs? or better a solution?
thanks in advance...

My 3gs disconnects from my wi-fi at night while plugged into my wall charger causing my AT&T data usage to go over my 200mb plan. I like to listen to a radio app overnight and this situation is quite annoying. AT&T forgave the overage but had NO solution to my paltry wi-fi delimma. I am going to try the "sync while connected to wi-fi" setting in I-Tunes but I am almost afraid to try it again because the overage may not be forgiven this time and It's not worth the hassle. I have been using my Macbook instead for this duty with no worries of an overage. I'm also a Pandora fan and this has limited me to just using my I-Tunes library for music instead of Pandora. This is a problem that benefits AT&T and I'm sure they bill for LOTS of overages because of this problem. I hope the I-Tunes solution will FIX this glitch.

Why is wifi connection lost after sleep/wake mode?

I've had this iMac a little over a year and had not experienced this until a few days ago. Every time my computer comes out of sleep mode the wifi is no longer connected. I must turn it off wifi and turn it back on again to re-establish a connection. Any suggestions? Thx!

Hello tim290,
After reviewing your post, it sounds like after the computer wakes from sleep it does not connect to the internet. I would recommend that you read this article, it may be able to help the issue.
Wi-Fi: How to troubleshoot Wi-Fi connectivity - Apple Support
Symptom: After restarting or waking from sleep, my computer might not connect to the Internet
After waking from sleep or starting up, your computer may not show that it is connected to a Wi-Fi network.
After start or wake, your computer may indicate that it is connected to a network, but does not connect to the Internet.
Solution
Use these steps if your computer does not automatically connect to your desired Wi-Fi network.
Check your TCP/IP settings in the Network pane of the System Preferences. Click the "Renew DHCP lease" button
Choose System Preferences from the Apple menu.
Choose Network from the View menu.
Select Wi-Fi, then click the Advanced button in the lower-left hand corner of the screen.
Click the TCP/IP tab from the top of the screen.
Click the "Renew DHCP lease" button.
Select the Wi-Fi tab and view your Preferred Networks list.
Select each network and click the minus (-) sign to remove those networks from your Preferred Networks list.
Click OK and close the Network preferences.
Remove your stored network passwords using the Keychain Access Utility.
Open Keychain Access from /Applications/Utilities. Your window will look like this:
Remove your AirPort network passwords from the login keychain: Select the "login" keychain from the Keychain sidebar. Click the "Kind" column to order the list of keychain items by their type. Remove all entries of the kind: "AirPort network password".
Remove your AirPort network passwords from the System keychain: Select the "System" keychain from the Keychain sidebar. Click the "Kind" column to order the list of keychain items by their type. Remove all entries of the kind: "AirPort network password".Note: The above steps will remove your Wi-Fi network passwords. If you do not know them, or if your network does not use passwords to restrict access, you should contact your network administrator.
Restart your computer.
Join your Wi-Fi network. You will need to enter your password for your network again if it requires one.
Thanks for using Apple Support Communities.
Have a nice day,
Mario
