MBP won't connect after sleep

For some reason my MBP decided it doesn't want to find a netwerk when I wake it from sleep. My wireless icon is not high-lited. It isn't a problem to connect manually though. I just click on the icon and scroll to the netwerk I want. In my house I use a airport basestation to connect both my MBP and iMac G5. The G5 doesn't have any issues and connects fine everytime. Why is my MBP not automatically connecting? Is there maybe an option to turn this feature on that I can't find and may have reset itself? Thanks for any help.

HI, I changed the settings in my linksys WRT300N V 1.1 from open to wep ( all other wireless settings to default) and now the problem is gone after two days from waking up from sleep several times. The signal is also more reliable.
Problems started after updating from 10.4.10 to 10.4.11 which included Safari 3 and the last airport update. I tried the other suggestion in the posts related to loss of signal and intermittent signal but none worked. When changing the security setting I also changed the name of the SSID and set it to transmit SSID.
Good luck

Macbook Pro won't login after sleep (sleep with low battery -- mac turned off maybe it's called save sleep)

Macbook Pro won't login after sleep (sleep with low battery --> mac turned off maybe it's called save sleep)
So if I hit the powerbutton my mbp booted like it is booting from the save sleep (so very fast and the login screen is there in about 10 sec.and there is no apple logo while booting just the desktop screen in "unsharp" ore foggy however...)
Then when i see the login (if the keyboard backlight turned on) i wand do tipe in my code but it won't work... the trackpad is not working; and when i plug-in a usb mouse the mbp is not powering on the usb-mouse (laser is off)
Why is that this way?
Is there n option to wake up the mbp fromm deep/save sleep without haveing issiues after that?
THX

Sorry for such a long delayed response...
I was able to get to an apple store this past weekend, and let me tell you... I'm about finished with there great "support".
Right before I went to the store, I tried to eject a disk. Well the cloth in the SuperDrive (I assume to protect the drive from dust and such) Pulled up with my disk. So I get the Apple store, describe my problem and what happened with the cloth piece. The "Genius" writes up a form and tells me they have to run diagnostic and it will take a couple days... and I will get a call when its done (1-3 days).
Well on day number 3 I called up the store and they told me it was ready to be picked up? I asked if anything had been fixed and they told me they could not reproduce my "sleep issue", so they couldn't fix that.. but told me the cloth piece in the SuperDrive had been fixed.
I drive an hour (one way) to the Apple store to find that all they did was PULLED OUT the cloth... they did not replace it! So basically I have a hole for a Super Drive.
I asked why I was not called to say that my computer was ready to be picked up... didn't get an answer on that one.
I asked why my SuperDrive was said to be fixed, when nothing was done... they told me that it would have to be sent out to the factory store for that to be fixed (FIRST TIME THEY MENTIONED THAT!) Oh, and that would take 5-7 business days. Well that's not going to happen right now considering I'm a college student that NEEDS a working computer!
So I go home, angry... start just putting all my important documents back on the computer. And the screen starts blinking!!!! I guess now I have the same thing described in another post on these forms...
Lets just say that I'm not very happy with Apple right now! If anybody else has success on either the sleep issue or the screen blinking issue, please let me know!
Thank you!

Problems auto-connecting after sleep & startup (Changed from WPA to WEP)

Okay, I know there have been several issues similar to this, but after two days of sifting through posts, I still can't resolve this.
A few days ago I switched my AirPort network security from WPA to WEP-128. This was required to allow my Nintendo DS to connect to the netwrok, by the way. After the change, two similar, but slightly different problems started:
My 15" PowerBook G4 no longer auto-connects to the network at startup. The network is listed in the drop-down, and connects with no problem when I choose it manually. The computer seems to have no problem re-connecting after waking from sleep, which is odd because...
My other PowerBook, a 12" G4, won't auto-connect at startup AND won't re-connect after sleep. As above, it has no problem connecting using the Keychain once the network is selected from the drop-down.
So far I have tried, on both machines:
- trashing the system airport prefs
- deleting and resetting the network's keychain entry
- repairing the keychain (no errors found)
- turning off some unneeded power mgt options
- disconnecting USB peripherals
I have also reloaded the software on both my AirPort Extreme base and my AirPort Express hub, as well as restarting both hubs. I've also made sure that AirPort is at the top of the network connection list.
Both laptops are running 10.4.3 and have all the latest software updates installed.
What am I missing?
Thanks.

Both of these replies are helpful, in that they help confirm something I figured out this morning, almost accidentally.
One thing I didn't mention was that during the change from WPA to WEP I changed the network password. Now, I assumed that since the Keychain seemed to be working and I could get on the network manually without needing to enter the password each time, that meant the new password had correctly propagated throughout the system.
So, this morning I go into the Network settings, switch from Automatic to Preferred, select my network, look at the properties, and notice that somehow it has way too many bullets for that to be the correct password. I re-entered the password and that seems to have solved the problem. The new password I had entered somehow didn't make it into this setting. I guess trashing the network prefs, or renaming the network would have had the same effect.

Won't restart after sleep

This is a common if infrequent issue, but my new MacBook Air running 10.9.2 won't restart after sleep. I've connected it to a Thunderbolt display, and after sleep all I get is a finger pointer on the display and nothing else. Only shutting down and restarting works.
I've seen this issue in other posts, but it's never affected me until I replaced my previous MacBook Air with a new one.
Has anyone got a resolution? It's very annoying with applications and files open on crashing.

23" momitor won't wake after sleep after installing Radeon AGP 128 dual dvi

hello,
My monitor won't wake after sleep mode. This is new after installing the radeon 128mb dual dvi card. I assumed it should be "ready to go" because I bought it at Tekserve, which sells and fixes Macs.
And if I have my 17" acer display connected the desktop, upon wake-up, partially swithches to the 17" -minus the tool bar. And without the tool bar I cannot access the OS or preferences. I have to restart.
Is there a driver to solve this dilemma? I can keep the computer on without sleep and turn off the monitors but that seems to be a poor solution.

Both iPod and iPad won't connect after update.

Both iPod and iPad won't connect after update. iTunes says "can't allocate a resource"

I had the same problem after updating to iOS 7 today. I did follow the advice on another site, but additionally rebooted my iMac. Worked after that.
Follow these steps to reset the Lockdown folder:
Disconnect all iOS devices from your computer and quit iTunes.
From the Finder, choose Go > Go to folder.
Type the following and then press Return:
/var/db/lockdown.
The Finder window should display one or more files with long alphanumeric file names.
In the Finder, choose Edit > Select all. Then, choose File > Move to Trash. Enter an administrator password if prompted.
Note: Do not delete the Lockdown folder itself. Delete only the files contained inside the Lockdown folder.
Reconnect your iOS device and open iTunes
My Additional step: reboot the Mac. Your iPad should give the first indication that it has worked by asking you to "trust this computer" or some such. Agree. Then iTunes should have reopened with your iPad showing and syncing.

Possible fix for OS X 10.5.7, losing connection after sleep, restart

Possible fix for OS X 10.5.7, Airport, losing connection after sleep, restart, or cold reboot.
Issue: (For OS X 10.5.7 on iMac5,1, Intel Core 2 Duo)
=============================================
- After sleep, restart, cold reboot, even though cannot connect to Internet, but the AirPort bars are still full, as if connected.
- Losing Internet connection after sleep, restart, cold reboot.
Possible Fix:
1.Open Network Preference, click on the Location drop down list > Edit Location... > click on the wheel button > Duplicate Location.
a)Select this newly setup location; Use Diagnostic button to connect to the internet. Select Network or enter WEP password if necessary.
b)Test to make sure you can connect to a web page.
c)Go to sleep & wake up.
d)This time, the Airport bar will start to show correctly. Before, it will always be full even when not connected. Now there will be no bars or grey out when not connected.
2.On the left hand side of the Network Preference Window, there is a list of services, such as Airport, build-in ethernet, built-in FireWire, bluetooth, etc.
a)Click on the wheel button on the bottom of the service list; select Set Service Order...; move Airport to the top of the list.
b)Delete any services which you are sure that you are not going to use, such as Bluetooth, etc.
3.Pick one of the locations mentioned in #1, and make it sure it is connected. If not, use Diagnostic button. If you have to select Network or enter WEP password to connect, make it so.
a)Check to make sure you can connect to a web page.
4.Go to sleep & wake up. The Airport bar should be filled up quickly. Try to connect to a web page.
5.Restart computer. Test a web page.
6.Shut down & Start computer. Test a web page.
7.When everything is working fine, you can delete the extra location that you created in step #1.
8.Click the lock on the left lower corner of the Network Preference window to safeguard the setting.

If my assessment is correct, the LIDE 200 driver is version 14.8.1 and dated 26-Sep-2008. It is possible that the driver will not work with the latest version of OSX. I would advise that you contact Canon and ask them the question.
(Removed link because of the way Flash drives the Canon site).
It is not uncommon (though irritating) that devices no longer work when an OS is upgraded. One has to ask the question if (or why) the driver was not written in such a way as to be OS version independent.
Chris
I spoke to Canon over here in Australia. Not helpful at all. In fact they were about as useful as an ashtray on on motorcycle. Having said that the tech seemed to think that there would be an update soon. But that is assuming that Canon are aware that there is a problem with that Scanner under OS X 10.5.7.

Security Update 2007-004 v1.1 did not fix connectivity after sleep

I installed the new security update (2007-004 v1.1) which was supposed to fix airport cards from disconnecting from their wireless network after sleep...but it didn't fix the problem. Is anyone else STILL having trouble?

I was having the same problem with connectivity after sleep, but once I used the Security Update 2007-004 v1.1 I no longer that THAT problem, but now I have another,....
in MAIL, there is definitely a 'long' pause before graphics are displayed. Or while using Safari, the text for a new page will display fairly quickly, but again there is a 'long' pause before the graphics show up. I am comparing the time before the first 2007-004 update and now. Before, the graphics downloaded fairly quickly. In the MAIL program, just clicking on an email caused the graphics to appear, in fact, they were just THERE. But now, again there is that longish pause before they appear.
Has this happened to anyone else? And ideas what I can do?

Mission Control won't work after sleeping. Upon Start up it's fine, but after sleeping it won't work by track pad or keyboard.

Since updating, Mission Control won't work after sleeping. Upon Start up it's fine, but after sleeping it won't work by trackpad or keyboard. I'm sure I use Mission Control more than most, so it's really irritating for me.

No, the versions of iPhoto on the iPad and on OS X are totally different.
What Apple ID are you using for the Mac App Store? Who else has access to that Apple ID, or what possible other Apple IDs could be in use? It's possible you'll need to purchase iPhoto to get the upgrade, though I'd think Software Update should offer you the correct version.

Skype 7.6 (409) Cant connect after sleep/lid-close...

Skype cannot connect after sleep or after I've closed the lid of the computer. I've tested this out and it sometimes opens up the main skype chat window however I am offline and cannot go online.
I've tried several methods;
- deleting $TMPDIR/Skype directory
- deleting my username folder from ~/Library/Application Support/Skype
- deleting ~/Library/Application Support/Skype/shared.xml
- Re-installing skype
The only solution seems to be restarting my computer so I can relogin with skype. However this is not an acceptable solution.

I couldn't find the edit button . I've succesfully found the problem causing it. However since I can't debug the skype app I am unable to find a solution as of yet.
My culprit was vagrant. Everytime I boot up a vagrant instance of a vm (which is whenever I turn on my computer) I get dropped out of skype. I've tested this as far as starting a vagrant during a skype call. The call doesnt drop (it kinda stutters) but I am logged out of skype immediately.
The things vagrant does are logged here;

I suspect there is a port misalignment, however the ports I've specified should not conflict with skype afaik.

MBP won't connect to external Toshiba LCD, MiniDisplay to DVI to HDMI

Brand new Mac Book Pro, 10.6.4, won't connect to external Toshiba 40" LCD display. I'm using a MiniDisplay to DVI-D adapter coming out of the computer. Then a 10' DVI-D (single link) to HDMI cable running to the display. When I connect the external display the MBP "searches" for a few seconds, but doesn't connect, and the Toshiba display reads: No video signal. This is with the MBP open and display on. BUT, sometimes when the MBP lid is closed, and I connect the display IT WORKS for a about 20 seconds, then the computer "goes to sleep" by itself, and the display shuts off. Strange problem... Also I've tested the computer with a 24" external Planar display (MiniDisplay to DVI-D), and it worked fine. Also the TV and DVI to HDMI setup works fine with my older MBP that has a DVI output. Any ideas...?

The adapter works perfect with other computers (mac pro and dual 24" displays). The problem only seems to happen with this new MBP, Toshiba TV, and the adapter configuration I described. I'm trying to find a friend with a similar new MBP, and try it with theirs. With so many components, it's hard to isolate the problem (especially when all the pieces seem to work properly on their own).

T440s in Windows 7 Pro loses Wifi connection after sleep 7260AC

Hi guys,
I keep having issues waking up from sleep with my T440s. It WILL NOT connect to wifi and the wireless adapter under windows adapter settings disappears. Only thing that fixes this is a reboot. I have removed "allow windows to turn this device off" under wireless settings.
Driver: 17.12.0.4
Dated: 28/08/2014
Software: Lenovo Access Connections
I do not use windows to connect to WIFI. I have dedicated profiles for each of my wifi networks at home and work.
This is a serious productivity killer.
Any help would be appreciated.
Thanks!
Solved!
Go to Solution.

This is a well-known issue with the AC card. Go take a look at the Intel forum.
You don't necessarily have to reboot to get the card back. Right click it in Device Manager and then disable/enable. It will come back online.
Some tips that have worked for many:
-DO enable the power saving setting. If I disable it on my T440p, the card is offline upon wakeup.
-Ditch ProSet and let Windows manage your wifi. Profiles might be convenient, but...
-Ad Hoc QoS - WMM enabled. Enable it on your router(s), too.
-Ht Mode - VHT
-U-APSD support - this one can go either way. Some leave it on and don't have an issue. Some have to disable it to have the card work after sleep. You have to play with it.
And, I really believe that the router/modem type can make a difference, too. Some just don't work right with this card no matter what you tweak on the card. With this card, I think an AC router/modem is the way to go.
Another thing is the driver itself. I had wake issues when I first got this ThinkPad about 10 months ago. Then, Intel released v 16.6 and that one fixed it. I've tried all of the 17s released since and all of them caused sporadic failures to wake. So, I have always rolled back to 16.6 and it always wakes.
Note this: If you use Lenovo Update, it won't create a restore point in Windows so your "Roll Back Driver" button might be greyed out in DM. Always manually create a restore point before you update a driver. And, if it's working, whatever it is, leave it alone. If the release notes don't address an issue you're having, skip it.
Driver updating is way oversold here and elsewhere. If you're determined to update anyway, at least don't be an early adopter. Let other peeps do it first and then come back here and see about the complaints! Also, you can download the driver at Intel in their Administrators sets of drivers. Bare drivers and no software overhead.
Good luck.

MBP won't connect to Time Capsule

OK, this is odd for some time now my Time Capsule has been flashing the amber light but I've still been able to connect.
Today when I woke up my MBP (Penryn, OS 10.6.8) the Airport/Time Capsule (2nd Gen, v7.4.2) did not connect. However my iPhone did have a connection. I could see my network from the Airport icon so I thought it might have something to do with the amber light flashing and so I connected by ethernet and reset all my settings and now I have a green light again. Yea.
But, my MBP still won't connect to the network. It see's it, it just won't connect.
When I open System preferences the Airport is amber (and Airport is on and connected). When I click on Assist Me and Diagnostic the Airport shows green but all others are red.
If I plug in the ethernet ISP, Internet and Server all turn green but but Airport Setting and Network Settings both fail (red)
When I use the Assistant in Network Preferences it won't accept my password.
Oddly my iPhone still connects using the original password but now when it wakes up my iPhone it's showing 3G for about a second and then switches to WiFi. That's not happened before.

OK, spent time at the Apple Store and they told me my Time Capsule was dead (even though my iPhone could still connect). They suggested there was an outside chance if I reinstalled the OS (didn't help).
Then I called Apple Support and they said I needed to call my ISP and get a bunch of info (which when I called my ISP they had no clue what I was referring to).
Finally called Apple Support again and a guy named Greg told me to quit all my open applications, open a new Finder Window go to the HD>Library>Preferences. Scroll to the very bottom and trash the System Configurations Folder. Empty the Trash. Shut down the machine for 30+ second and then restart.
Bang, all is working great. After I got on the phone with Greg it took less than five minutes and I'm up and running like a charm.

IMac won't wake after sleep

Hi
I have a brand new iMac 21.5" with Hybrid drive.
Its OS and apps are fully update to date.
Strange thing is that it won't wake from sleep.
To reboot, I have to turn the power off at the wall and back on again. Neither of the usual
wake/reboot processes work (holding the power button briefly or holding the power button for
> 10 seconds). No combination of opt/ctrl/cmd/power work either. I have to turn it off at the wall
and back on again, after which it immediately boots.
I've reset the SMC and NVRAM/PRAM.
I've checked the power options - which are set to defaults (sleep after 15 IIRC).
I've also checked the console log at the time of sleep - and there is no indication of anything
going wrong (an example is below).
Does anyone have any other ideas as to what I can try before going through the painful process
of sending it into the shop?
Many thanks.
Paul.
Console log below. You can see the machine went to sleep after 12:05pm, and I woke it up and 8:20pm. There seem to be no unusual messages in the middle.

I have gone to the apple support team - and they took me to the standard apple "what happens if your mac won't turn on" page
(If your Mac won't turn on - Apple Support) and walked me through the standard checks (which I'd already done).
The support guy thought it was a bad driver - I'm not so sure as I haven't installed anything new (just updates).
Anyway - I was just hoping/wondering someone in the wider community had seen this issue before I take the machine
in for servicing.

Airport after 10.4.2 Will Not Connect after Sleep

After my iBook G4 goes to sleep it will not reconnect to the internet.
It shows connection.
It shows me the IP.
It will not allow me to do anything online.
I have to quit all internet prorams mail, safari, firefox etc...
Then I have to reset the location over and over and try until it works. Sometimes right off the bat sometimes it takes 10 minutes. This is completely frustrating since even the network diagnostic is showing internet, ISP, etc.
I've rebuilt my keychain.
I've rebuilt the WEP password
I've changed my computer name to be one word no spaces.
I need help! My wife cannot use this computer if it won't connect without interaction. I never had this issue before 10.4.2 was installed.

Henry,
Thank your for the helpful link.
I created a new location based on the info in the link you provided.
It worked.
Now, the iMac G5 rejoins the network automatically after sleep or restart.
I don't know if level 4's need point, you and Frank C. (author of the info at http://discussions.info.apple.com/webx/.68ae4ead) just got some more from me.
