Network Password not accepted, works on other computers

We have an Airport extreme (looks like a UFO). Everything worked fine last night, but this morning our MacBook Pro cannot join the network because the password times out - Have rebooted both computes and Airport, no success. Other computers in the house can still log on to the network with the same (old) password - Any help?

Hello Barbara Raley. Welcome to the Apple Discussions!
Try the following on your MacBook Pro:
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.
If this doesn't solve the problem, I suggest disabling wireless encryption on the AirPort Extreme Base Station (AEBS), and then, reestablish it with a completely new password.

Wi-Fi Network Password Not Accepted

I'm in an AT&T area and using a 2Wire Wireless Router. Used my home wi-fi for the first time for my phone. I entered the password to my router and I thought it worked. I tried to go to YouTube and my wi-fi now says "Authentication error occurred". I tried several times to enter and no such luck. So I went to my PC and re-set my password to the router. Now when I want to go to YouTube, my network name comes up and the word "(unchanged)" in the password field. I press Connect, and I get "Incorrect Password". I enter my new password and I get again "Incorrect Password".
Do I need to re-set my router password again? Don't know what to do. Would like to use my wi-fi so I don't use up my data quickly.

First off turn off your modem and your router and your phone. Going on assumption you changed the password to your router correctly write it down exactly as entered. (uppercase and lowercase and numerials if you used them)
Now in this order turn on your broadband modem, make sure its fully up to working order. Then turn on your wireless router and again make sure its fully cycled up before you turn on your phone.
Now assuming your routers password is correct, your device should see your ssid of your network. If its found click on connect, then when it asks for the network key enter it exactly with no spaces etc. Then click ok etc.
If the password is correct you should have no problem connecting. Please note if your phone was upgraded to Jelly Bean OS you may have to buy a new up to date router to access your network. You may want to stop at a public wifi to see if you can connect I use my auto dealer wifi, or my friends wifi. If you can connect everywhere else the router at home may be your issue.
Good Luck

Deskjet 3520 wireless network password not accepted but it is the correct password

I just got this Deskjet 3520 printer and it's supposed to use my wireless connection. I got as far as it selecting the correct wireless network and the correct password was already there but after configuring a few minutes, it said the wireless network rejected the password. This happened a few times and I tried both the wireless network key and the system password. So I don't have a wireless printer at this point. I hope someone can help. thanks.

Hi mwell10,
I suspect you would have to either call your router provider or you can go into the EWS (Embedded Web Server) of the router using its IP address.
To get the IP address of the router you can click on the airport/wifi icon on the top right of the Mac screen ans select *Open Network Preferences*. Then in the Network Preferences you will see the Router IP address.
Take this IP address and put it into the address bar of a Safari browser.
Use the Thread below for further assistance.

WIFI stopped working after I woke the computer up, now says connected to the network but not the internet, all other coputers and devices connected still with no problems, have pinged IP address from router and got the message "4 packets sent none receive

Hi,
WIFI stopped working after I woke the computer up, now says connected to the network but not the internet, all other coputers and devices connected still with no problems, have pinged IP address from router and got the message "4 packets sent none received"... Help
I have tried network diagnostics which doesnt help... The only other ting is, when I woke the computer up it said tat another device was using my IP... My wife had plugged her phone into the computer to charge etc but even when i turn wifi off on the phone there is no change... also in settings on the phone the IP address is different...

The answer to your question is - neither!
Your PC should to configured to obtain an IP address automatically, and to obtain DNS server IP addresses automatically, from the Airport Express. This is the way Windows (and Macs for that matter) are configued by default, and that is the way most people have their computers set up. If you manually configured your PC's IP address to be the same as your wife's Mac, it certainly explains why your PC is not able to access the internet.

Apple id password not accepted on icloud

why is my apple id password not accepted when I try to login to iCloud? The same password worked when I tried to login to support to post this question!

If Settings>iCloud is showing your old email address, go to https//appleid.apple.com, click Manage my Apple ID and sign in with your current iCloud ID. Tap edit next to the primary email account, tap Edit, change it back to your old email address and save the change. Then edit the name of the account to change it back to your old email address. You can now use your current password to turn off Find My iPhone on your device, even though it prompts you for the password for your old account ID. Then go to Settings>iCloud, tap Delete Account and choose Delete from My iDevice when prompted (your iCloud data will still be in iCloud). Next, go back to https//appleid.apple.com and change your primary email address and iCloud ID name back to the way it was. Now you can go to Settings>iCloud and sign in with your current iCloud ID and password.

Gmail Error: Username and Password Not Accepted?

Okay, once in a while my e-mail actually works on my I phone but about 90% of the time I get this notification; Cannot Get Mail: Username and password not accepted. Does anyone else have this problem or know how to fix it? Oh yeah, I'm using 1.0.2, gmail, and I'm positive my password and username is right.
Message was edited by: one11archerave

I think the problem is solved. Last night I was on my friends computer and I accidentally stored my gmail password. I couldn't figure out how to delete it so I changed my password and then updated my iPhone with the new password. Ever since then I haven't had any problems.

Cant restore back up from iCloud as password not accepted

when trying to restore an 1phone 5s from iCloud back up my password is not accepted..i then go to iforgot, change my password retry the restore process and get the same issue.I have tried turning find phone off, starting again but still cant access back up because password not accepted.

I can't change my DNS settings. I'm trying to restore while setting up my phone. If I change the DNS settings while on the phone, and then restore the phone and try to restore from the back-up on my iCloud, it won't save that I've changed settings to use Google's public DNS. I would log onto my university's secure wifi instead of their guest wifi, but unfortunately I can't. because that involves an installation, which I can't do if I restore my phone and am trying to set it up.

Signed up on furefox desktop 2/2. No problem. Today password not accepted. Asked for help 3 hrs ago and never got email and nit in spam

Was sucesssful signing up and using firefox on desktop yesterday. Today user name and or password not accepted. Can't get emails-nothing. Asked for help with password and never got email. This was 3 hrs ago and not in spam folder

Password for what? Signing up for what?
Firefox doesn't need a password for a person to be able to use it.
Firefox shouldn't affect your ability to get email - Firefox doesn't do email, but it will allow you to access your web-mail service.

Password not accepted for network

Hi,
im having a problem connecting to my home network as it will not accept my password . The ipod keeps displaying 'incorrect password for'..., the encryption is WEP based but i have also tried using WPA. There is nothing wrong with the system as my laptop is always connected to the network
Thanks

ngfjdgbkrngljr,
You can try entering the 13 character ASCII key with "quotes" around the key.
If that does not work you may have to get the HEX key from the router configuration page.
It may be easiest to contact the router manufacturer or Internet Service Provider that gave you the router and ask them howto configure the router with WPA2 Personal wireless security. These links will show why WPA 2 personal is easier to use.

When I compose an E-mail my address book will not open when I click on TO or CC, but it does work on other computers and also if I use explorer.

My address book will not show when I click on the TO or CC button, a mozilla page does open but there is no content. My E-mail accounts work fine on other computers. It also works fine on this computer if I use Explorer instead.

ID password not accepted anymore (once worked)

Good morning,
I am kind of desperate...and I hope somebody is familiar with this problem.
I have adobe reader 11 XI, the latest version.
I am taking a trainingcourse at Learningtrain. They provide lessonmaterial with certificates / id only.
I created an ID and sent that to my teacher. fyi: I was strongly advised to switch off the automatic update option..as adobe deletes id's... and i did.
The teacher had it all set up. And it worked! I could succesfully open the material with my password.
now the issue:
But it only worked once! Very strange. the ID is still there,but adobe does not accept my password any more
so i cannot open the file anymore. My home work is due today... and it is a lot ;-)
I have checked and double checked my password and is must be correct.
My teacher advised me to delete this id, and to create a new one. but that does'nt work as reader still askes
for my password when i want to delete the id.
so i decided to deinstall reader and install again (who knows...) but it lookes like i cannot delete it.
fyi: I also have adobe acrobat pro on my pc as i have the whole adobe css range. but I have exclusively used the reader.
Hope you can help me.
Kind regards Asha

Well, if you can't uninstall Reader, you probably have something wrong. But, if you were advised against updating, uninstalling will surely be worse!
I'm afraid I don't know what kind of password this is, there are so many possibilities. What does the prompt say? A screen shot would be good (BUT DON'T TRY TO EMAIL IT IN REPLY).

Internet works on other computers, not mine...

Okay, so. We had been having some internet problems last week, but after resetting the modem, and temporary outage in our area, it went back up. However, I'm finding that although all the other computers in the house are able to connect to the internet, my Macbook can't.
My mother's eMac is connected to the same network as mine, and the internet runs fine on it, a bit slow because of the computer, but all the same it works. On my computer, the airport icon in the menu bar shows a full signal strength, but I'm not able to access even Google. Network Diagnostics says that it appears to be working, but it can't connect to the internet.
This really confuses me. Why is the eMac able to connect to the internet on the same network, but the Macbook can't? I would download a system update, but that requires...the internet. The worst thing about it is that my Macbook has always worked on the network until that day.
Please save my computer -- summer vacation's just around the corner, and I can't survive without it! TT_TT

Are you connecting the AirPort Extreme to a simple modem (it will only have one ethernet port), or is the device a gateway (combination modem/router with 3-4 ethernet ports)?

So I updated my computer to 8.1 I don't know if I synced my ipod after that, but I know immediately after updating iTunes, I began to receive an error message saying iTunes recognizes that I connected an iPod, but can't identify properly.
I've tried uninstalling and reinstalling as well as restarting the computer, trying different USB ports. it works when I connect it to other computers.
