MBP won't pick up network after being turned off

Good morning.
My new MBP is working great and I love it. The only thing that I having some problems with is getting it to remember my network connection when it is turned off and back on.
Here's what I have set up. I have a wireless network in my home with WEP encryption and my SSID is not transmitted.
If I go up to the network (antenna) symbol at the top of the screen, click on it and choose other network, enter my SSID and the WEP password, it connects and stays connected.
If I turn off my MBP and then back on either immediately, later in the day or another day, I have to go through this process again. It doesn't seem to remember by settings for my network. My wife's and my daughter's ibooks both remember the settings. Can't think of what I might be doing wrong here.
Any help or suggestions would be appreciated.
Thanks.

The password for the wireless router is out of sync (corrupted). To remedy the situation you can delete the offending keychain item from the system keychain. You can't view the passwords for items within the system keychain, but you can delete an item so it can be recreated.
The trick is to delete the keychain item in the system keychain for the resource that's giving you the trouble, e.g. Airport network password.
1. Open the Keychain Access program
2. Select System keychain.
3. Select the keychain item you want to delete, and choose Delete from the Edit menu (you will be prompted for an admin password).
4. Restart
5. Next time you enter the password to access the wireless network (or resource) and save to keychain, the item will be recreated.

Now wifi will not turn back on automatically in the morning after being turned off all night. Use to be ok before now. Is it the new update 7.1? Help

Wifi will not turn back on in the morning after being turned off all night, it use to work for years. Is it the new 7.1 ?

Yes that what I mean, after the phone has been turned off all night, when I turn it back on the morning the wifi will not turn on by itself. Eventually by turning off and on the main phone switch and the wifi in settings it sometimes come back on! Then I'm ok for the rest of the day even when I leave the house and come back it's ok. Only first thing in the morning, strange that it doesn't wake up like it use too.
Thank you

Screens do not turn back on after being turned off by windows power saving

I have Windows 7 on my T410 set to turn off my monitors (I use a docking station) after 15 minutes of inactivity.
The problem is that when I come back to the computer, I cannot get the monitors to come back on. They actually turn on, but remain blank. No matter what I do they won't come on. This happens every time.
I have found that if I close the lid and make it go to standby mode, and then open and come out of standby, it will SOMETIMES make the screens show a picture.
What is also weird is that when I open the lid, sometimes Windows will ask me for my password, and then after I enter it, the screens will go blank again. So I have to keep going to standby 2 or 3 times till it works.
This happened both on the Lenovo version of Windows 7 and my own clean version of windows 7 that I installed.
Any ideas?

For the time being I think I'm just going to plug my modem directly into the ethernet port. I can't stand that this ******** is happening with a brand new iMac when I just got done dealing with a fried iMac G5. Is Apple ever going to make another iMac that doesn't have something wrong with it?
If anyone knows of any fixes or other helpful information I would greatly appreciate it.

Zen Mirco Formated and fully charged STILL goes flat after being turned off all nigh

This is starting to annoy me now, I formated the unit and then allowed it to be fully charged, now in the morning when I awoke after leaving it off all night it was completely flat again. So this rules out corrupt files in the library.
And from all the other things I have done I have ruled everything else out, so come on creative!
Whats going on?

It's strange that the Zen Micro does it but the Zen Touch doesn't. It could be because of the massi've battery life in the Zen Touch but I charged my Zen Touch up completely about 2 days ago and turned it on today and it's still showing 3 bars. I really hope they remedy this problem because it's a bit annoying taking it with me in the morning only to have the battery die later that day.

On battery MBP won't go to sleep after being inactive for 5 minutes

Okay so in energy saver under system preferences, I have it setup so that the computer should go to sleep after 5 minutes of inactivity when running on battery power. However multiple times I have left teh computer on battery only to come back in a few hours and the MBP was still on and not sleeping. I had itunes and safari open, but itunes wasn't playing any music. What does it take for the computer to be "inactive". Do I have to close all of my applications?

I have had similar issues with this. Seems the:
Library/Preferences/SystemConfiguration/com.apple.PowerManagement.plist
Gets corrupted and must be trashed, reboot reset PRAM and reset your power management settings.
I hope this helps.

Why doesn't MBP return to its normal temperature after I turn off a heavy program?

Hello there, I've noticed that my new MacBook Pro runs at a very cool temperature while browsing websites and doing general activities. After I open up one of my work programs such as After Effects, Nuke, Maya, it will start up to heat up considerably on the left top corner, which is to my expectations. Now the problem here is that it does not cool down to its normal temperature after I have shut down all my work programs, the temperature remains as high as if the programs were still open and occupying CPU. Can someone help me with this problem before I take my MBP to a Apple Store for a fix?
Thanks lots!

You likely have a run away process from one of your third party programs that is not exiting or quitting, therefore hogging CPU cycles.
To determine this, reboot the machine, open your Activity Monitor and click "all processes" and sort by clicking on "CPU" this will make the processes taking the most cycles pop to the top.
now open your third party programs one at a time and get familiar with their processes, when you find the one process that appeared and taking huge CPU even after you've quit the program you have found your source.
Update this program or contact the developer for a explanation.
sometimes it will be a Apple process, which a OS X Overwrite should hopefully fix

Why does the EEvents message come up every time the computer is opened after being shut off?

You need to check the software you run.
Some officially supported and sold Mac versions of software use Wine for porting in some fashion or another. If some program you are running is spawning these Wine processes, its probably buggy and not shutting down correctly.
How to figure out which are Wine and which are not...?
Well if its a Cider ported game, you just see if there is a Cider logo on the game.
If its Wineskin ported, theres no super easy way to tell, depending on how much its been modified, but you can look inside the app (right click and "Show Package Contents") and go to Contents/MacOS and see if Wineskin executable is in there. Unless its a very old version of Wineskin it shouldn't be able to hang like that without major issues int he Windows software running in it, and I don't know any any company would release it if it was that buggy.
If its WineBottler Ported, you'll notice quickly because it launches X11 and runs the windows under X11... of course not all X11 apps are Wine, but if you have a program that launches and runs in X11.app then you can look inside it at Contents/MacOS to see if its Wine related.
It could also be Crossover, or a Crossover port of software... you'd have to dig around inside of its app too to see if it looked like one of those.

I updated my LG G3 this week and now it SUCKS! When I'm connected to WIFI, nothing on Facebook works. The photos and videos won't populate. I have to turn off the WIFI and only use the mobile data. Not to mention, I really hate the way it looks now.

I'm thinking of changing providers now.

Does the iOS device connect to other networks? If yes that tend to indicate a problem with your network.
Does the iOS device see the network?
Any error messages?
Do other devices now connect?
Did the iOS device connect before?
Try the following to rule out a software problem:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Power off and then back on your router
.- Reset network settings: Settings>General>Reset>Reset Network Settings
- iOS: Troubleshooting Wi-Fi networks and connections
- Wi-Fi: Unable to connect to an 802.11n Wi-Fi network
- iOS: Recommended settings for Wi-Fi routers and access points
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.
If still problem and it does not connect to any networks make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

I get a msg that the phoen wasn't backed up to the cloud and i won't go way. It also won't let me log in or turn off the phone.

Have you tried a reset ? Press and hold both the sleep and home buttons for about 10 to 15 seconds (ignore the red slider if it appears), after which the Apple logo should appear - you won't lose any content, it's the iPad equivalent of a reboot. You can then do a backup

Lost applications after PDA turn off

Hello everyone.
I’m developing an application for TPC-2006 with LV8 and PDA 8 module. I have deployed the application into the device and works fine, however after a turn off the application is deleted from the device. Anyone knows how can I store the application in a non-volatile memory zone? The TPC-2006 has no memory card.
Thanks

The TPC 2006 has, according to its data sheet, 64 MB SDRAM, 64 MB flash memory onboard, and a CompactFlash memory expansion slot. To me, means that it should behave like other PDAs. I thought I had a similar problem during the first hour of utilisation of my iPaq... until I discovered that the files where saved in the Document folder, while I was searching the Application folder... .
This being said, the TPC 2006 is a National Instrument product and you should obtain a better help from NI engineers !

I want to use Back to my mac. When I try to turn it on, it says "Back to My Mac may be slow because more than one device on your network is providing network services. Turn off NAT and DHCP on one of the devices and try again." How do I fix this?

Not sure if I am doing this right. This is my first time in the support community.
I imagine what I put in my heading was supposed to go in here.

Turn off NAT and DHCP on one of the devices and try again. See the documentation that came with your device for information about turning off network services"
Does anyone know how I do this? I contacted my ISP (Telus in Canada) and they did not know anything (not that they usually do).

Why do ISPs insist upon making things so difficult for their customers?
If you cannot get them to understand that you would prefer to use your own router over their piece of cheap junk, perhaps the information in the following will be useful:
http://keithbalomben.wordpress.com/2012/03/29/telus-actiontec-v1000h-hacks-and-i nformation/
Scroll down to DHCP Settings
You will need to log in with proper "technician" credentials. They are provided in the above link as
Username: tech
Password: t3lu5tv
... but these may or may not work. Try it, and if you cannot get anywhere at least now you know what to ask Telus to do in return for your business.

I have an ipad mini that won't power on. It was turned off to charge overnight. In the morning it was warm and now won't turn on no matter what I do. I've tried resetting using the power / home button combination and nothing works.

If you have owned the device, as in purchased from Apple, less than a year then there will be no charge to repair, or most likely, replace the device. If you have had the device more than a year you will be charged an out of warranty cost for replacement ($219 I think) and that is much cheaper than a new device. If you have Applecare+ then you have an additional year of coverage and the replacement will be $49 or $79 depending on when you got the Applecare.

Does the ext directory have the php_oci8.dll? In the original steps the PHP dir is renamed. In the given php.in the extension_dir looks like it has been updated correctly. Since PHP distributes php_oci8.dll by default I reckon there would be a very good chance that the problem was somewhere else. Since this is an old thread I don't think we'll get much value from speculation.

Why won't my ipod pause when I turn off the ignition in my car? It used to.

Why won't my ipod pause when I turn off the ignition in my car? It used to.

How is the iPod connected to your car stereo?, (via earphone jack or iPod dock connector)
By "pause" you mean that now it is playing thru your car stereo, while previously, it stopped playing thru your car stereo, when you switch off the ignition?
Anyway, I don't think it is an iPod problem, but you can try the
iPod Hard Reset -> Press Menu and Center button simultaneously for about 10 secs till the Apple logo comes ON.
Then release the buttons

refer to this Apple supprt Article on the 5Rs

This reset wont delete any of your songs, just put all the settings back to when you first took it out of the box.
