Can't connect to wi-fi after battery going dead

So last night a fell asleep with my MacBook pro on my lap (bad idea I know) and now I am totally unable to connect to my wifi. It shows that I have connection but I actually don't. My clock also got reset to December 31, 2000. This is the first time I've ever let my battery die on me. Anyone know what went wrong?

Hi,
Do you have the possibility to restart the router? Just to see if this simple thing can help. Have you tried to add/connect to the network manually via Settings > Wi-Fi > Menu button (three dots) > Add network.

My X61 can't connect wireless when i use battery!!!

TYPE NO.: 7673-AN6
i confused why it can not connect wireless when i use battery?!
the problem drive me crazy nearly, it means i must take adapter every time
i help every one can help me!
cheers,

Most of the functionality and problems are in the drivers. The hardware tends to be discrete testable functions though these days there is a fair bit of functionality in the hardware. The hardware tends to be implementing better defined protocols where as the to and fro of the higher level protocols tend to be what varies from Access Point to Access Point. The 4965AGN is a fairly recent chip set and the drivers are far from smoothly running.
The problems can vary from AP to AP so may work at home but not at work etc. Some have reported here that the 4965AGN setup doesn't work with the Cisco 1200 Access Point and I have yet to be able to get it to work under Vista with the equipment at any New York Starbucks. T-mobile do use Cisco equipment but I don't know which models.
Anything you can do to simplify the situation helps. Maximum power. No security. Disable IPv6 on the connection etc. Just to give a rough idea of the kind of thing that might be wrong here are some of the things listed as known issues or fixed according to the readme of the driver (Originating from Intel) that was released for the 4965AGN on 4/11/08.
There are several authentication issues with EAP, PEAP and LEAP which will cause it not to authenticate. There are also Vista EAP issues and some things which may resolve with SP1 which was pushed out on update last week. So there are many comnbinations of situations which may not work and it is important to test with different access points. Authentication and security has more issues. Also at the higher speeds such as 54Mb some of the security mechanisms will not be able to keep up. AES is the only mechanism which Intel expects to work at 54Mb.
http://downloadmirror.intel.com/15806/ENG/relnotes.htm
There have also been past issues where the cards are silenced for twenty minutes after a failure to authenticate and in many cases the card will not be in a valid state after hibernation. It is noticable that when you phone T-mobile the first thing the tech has you do is completely shut the machine down - not hibernate - and begin afresh.
Once you have uninstalled and re-installed the drivers and connection manager a few times it is also possible to be having problems with junk left in the registry.
I don't recommend adding the 4965 drivers directly from the Intel site. I would wait for the one that has come through the Lenovo testing cycle.
In reality for those who don't want to make maintaining their laptop a serious hobby (Hopefully all of us - Far too much time is wasted on wireless) it is really a matter of rebooting your machine at a given access point. Trying your luck and then shutting it down and going somewhere else if it doesn't work. Use wires when you can. At home if your access point doesn't work check your configuratiions, temporarily remove all security, restore factory settings on the AP, reinstall from scratch and if it still doesn't work replace it with a different brand of Access Point.
Of course it is intended to just work and for 95+% of situations Wi-Fi does. The 4965AGN is newer so it has its fair share of early life issues to get resolved. Vista also still has issues. If the problem you are seeing is only when you are on batteries you are lucky and LANOgre's instructions may well solve it.

Can't connect to wifi network after iOS update

Can't connect to wifi network after iOS update.

This does not work in my case.
Situation: we have wifi at home using WPA encryption.
The iPod Touch 8GB connected seamless to this network and anything was ok. After some days i could no longer connect, the iPod told me "connection to network 'networkname here' failed". Deleting the network and reenter the (correct) passphrase was no help, but changing the SSID on the router was helpful: the iPod could connect again ... for several days.
Now things stopped working again. Resetting network settings did not help either.
The iPod can see the network, is asking me for the passphrase and after several seconds telling me: can't connect. On the router log i don't even see a dhcp request, but other laptops work fine with the same wifi network.
That's a mess, i cannot and will not change the SSID every some days just to get the iPod working again.

Can't connect ipad to wifi after upgrading to ios6

can't connect ipad to wifi after upgrading to ios6

Additional things to try.
Turn Off your iPad. Then turn Off the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi. (This is probably not practical in your situation.)
On your iPad go to Settings > General > Reset > Reset network settings and see if that enables you to connect.
If none of the above suggestions work, look at this link.

OUtlook 2013 can not connect to exchange 2013 after exchange maibox member of DAG failed.

hi ALL
OUtlook 2013 can not connect to exchange 2013 after exchange maibox member of DAG failed.
Exchange environment contains 2 Exchange Mailboxesserver ,( one Failed , virtual Machine)
2 cas Servers
first databases could not be mounted but after we run the below command , users can use OWA but outlook could not connect
Start-DatabaseAvailabilityGroup -Identity DAG -MailboxServer MBX1
please support
thanks

Hi,
According to your description, I understand that Outlook client cannot connect to Exchange server 2013 while one member of DAG failed.
If I have misunderstand your concern, please do not hesitate to let me know.
I want to double confirm whether all account store in MBX1 experience this issue, users in MBX2 works fine.
Please run following command to double check the database status:
Get-MailboxDatabase –Status | select Name,Mounted,MountedOnServer
If it works in OWA, the issue may be related to Outlook side. Please run “Test E-mail AutoConfiguration” and “Outlook Connection Status” to get more details, expecial the setting of proxy server, it’s more helpful
for further troubleshooting.
Additional, please try to recreate a profile for testing. Besides, please move active DB back to MBX1.

How can be sure if my iPhone 3G battery is dead or just needs a recharge?

How can be sure if my iPhone 3G battery is dead or just needs a recharge?

Hi,
Thanks for the fast reply!
Here is what happens, and I've tried out several Apple chargers.
Unplugged, the battery charge icon shows only a tiny red bar for a charge, but it will come on.
The battery icon then displays a charging "lightening bolt" symbol showing charging when connected to any charger. But after a minute or two, the battery icon then changes to a "plugged in" symbol and the phone will no longer take a charge. I can recycle through this same sequence by unplugging and plugging back in the phone to a charger, but after a minute or two, that's it.

Ipod keeps turning itself on and off repeatedly until battery goes dead

please help.....my ipod just keeps turning itself on and off repeatedly until the battery goes dead. The only thing that will show up on the screen is the apple logo and then it will power cycle over and over and over! I have tried reseting it but I am limited to what I can do because the computer will not recognize the ipod when i connest it to my computer.

Take it to your local Apple Store

Battery going dead quic

My battery goes dead after /2 hour then quickly goes completly dead. I take the battery out and put it back in and it says firmware problem. Do I need a new battery?

What player and which type battery?

What happens if the Raid card battery goes dead?

I just got my MacPro, Raid card, and 3 SAS drive. I set it up as Raid 0. The battery in the Raid card is good for 72 hrs. And that is to save the raid cache. So what happens if I leave the MacPro unplugged for longer then 3 days and the battery goes dead? Do I loose all my data?
Thanks-Ray

With an orderly shutdown prior to disconnecting the power, no problems should arise.

Outlook can't connect with Exchange 2013 after migration from Exchange 2007

<style type="text/css">P { margin-bottom: 0.21cm; }</style>
Hello,
recently we've done a Exchange 2007 sp3 to 2013 sp1. Users can conect perfectly with OWA and with his iphone clients.
But the problem is they can't connect from his Outlook clients (2010, 2013), both internaly and externaly. Always fails with the message: The Connection to Exchange it is not avaliable.... Can't resolve the name of Exchange server.
To try to resolve it we've done:
- Check Outlook anywhere configuration en EAC: it is configure with and external url mail.company.com and internal server.domain.local. The security is the default Negociation, but we've tried all.
- Check the internal dns, there are records for mail.company.com and exchangeserverdomain.local pointing to the exchange local ip. Also there is a public zone company.com with the record mail.caompany.com pointing to the exchange local ip. Also we've made
records autodiscover.company.com and autodiscover.domain.local pointing to the exchange local ip.
- In the public dns from our domain there is the record A and MX pointing our public ip. There aren't any record Autodiscover but we think that the manial conection should work.
Check certificates: we've made a new self-signed certificate including all this internal and external domains and for all services.
- Check Outlook Anywhere block: we've cheked.
Currently server state:
- Old Exchange 07 server can't start, it was in very bad state and we achieved migrate the mailbox to the new server, after that we tried to uninstall, but it crashes with a public folder replication error. We got uninstall all the roles
unless the mailbox. After a restart it can't start.
-The new Exchange 2013 looks great, there isn't any trail of the old server, or we haven't seen anything in the EAC or shell.
I paste below the result of Microsoft Remote conectivity analaizer, with Outlook anywhere test. It is clear that there is a problem with that.
Sorry because the test is in spanish and I translated it with google, from here I only can access the tool in spanish.
We continue to try to resolve the problem.
Thanks to all in advance!

Can't Connect to WiFi Network After Changing Encryption

I have an iPod Touch that no longer connects to my wifi network at home.
Some background: I have an aipport extreme base station with three XP laptops, an iMac and a printer connected to it wirelessly. I use a WPA Personal password. My wife's iPhone connects without a problem.
I recently changed the password on the base station to WPA Personal because one of the laptops could not connect using WEP (solution to inconsistent hashing of 13 character password problem found elsewhere in this forum). Ever since changing the password, the iPod touch will not connect.
I have looked for, but cannot find the "Forget Network" button on the wifi network page on the iPod touch (I understand that button appears after you have successfully connected to the network). I have reset the iPod up to and including removing all data.
When I go into the settings>wifi menu, I see the network's SSID. When I input the password, I get a "cannot connect to . . . " message.
Any ideas on how to solve this problem?
Thanks

This does not work in my case.
Situation: we have wifi at home using WPA encryption.
The iPod Touch 8GB connected seamless to this network and anything was ok. After some days i could no longer connect, the iPod told me "connection to network 'networkname here' failed".

The iPod can see the network, is asking me for the passphrase and after several seconds telling me: can't connect. On the router log i don't even see a dhcp request, but other laptops work fine with the same wifi network.
That's a mess, i cannot and will not change the SSID every some days just to get the iPod working again.

Can't connect to SL mini after laptop update to Lion

Situation:
- Mac Mini on Snow Leopard 10.6.8 (mini-old)
- Mac Mini on Lion 10.7.4 (mini-new)
- Macbook Pro on Lion 10.7.4, update from Snow Leopard 10.6.8 since yesterday
I used to be able to connect file sharing and screen sharing from the laptop to both mini's. Since the update to Lion on my laptop, I can't connect to mini-old from the laptop.
- file sharing from laptop to mini-old before the lion update -> worked
- screen sharing from laptop to mini-old before the lion update -> worked
- file sharing from mini-new to mini-old -> works
- screen sharing from mini-new to mini-old -> works
- file sharing from laptop to mini-new -> works
- screen sharing from laptop to mini-new -> works
- file sharing from laptop to mini-old after lion update, with guest -> works
- file sharing from laptop to mini-old after lion update, with registered user -> endless pinwheel, no error in console
- screen sharing from laptop to mini-old after lion update -> endless pinwheel, no error in console
- ssh user@mini-old from laptop to mini-old after lion update -> works
So I can safely assume the settings on mini-old are ok (haven't been changed in many months).
I've tried deleting the caches with OnyX on the laptop, but that didn't help.

Update: 'several' minutes = 10
Same goes for the file sharing.
I've tried the screen sharing a 2nd time to see if it speeds up, but it doesn't. :-( Don't know yet what's going on, because the connection from the mini-new is instantly.
FYI: all three are on the same local network, so no remote 'across the internet' issues.
Anybody?

Can not connect to iTunes store after resetting password

After resetting password on iPhone 5,iPad can not connect to iTunes. Any one know how to correct?

I am having the same Issues.

Software Update can't connect to the internet after a new install of 10.6

I had a clean install of 10.6 and after that the Software Update can't connect to the internet (the status bar hangs at the beginning and finally it prompts me the internet is not connected) while all my other applications can.
Someone help me out?

I am having exactly the same problem as well.. has anybody managed to solve this yet? I have uploaded Snow Leopard - try to connect to Software Update - the menu bar scans a little then stops and then an error saying 'Not connected to the internet'' but the connection is working fine!!
Is this a SL issue? or just an overload with the Software Update programme? I cant do anything - no update for itunes/iphone software, etc.. most annoying.
Look forward to seeing some good news and some answers to this one.
Cheers
