MacBook Pro 2011 don`t accept Wlan Password

Hello,

we have several MacBooks (mod 2010) and other Notebooks in our Wlan Network.
Now we have the (mod 2011) and it don't accept our Wlan Password! The new MacBook will find all our Wlan Networks, if i type in the password it says "connection failed".
In one of our networks we have a WPA protection with numbers and letters.
In our WPA2 network we have signs like this "!", i think that's the problem. But the Mod 2010 MacBooks can all work with this signs. Wath we can do to connect the new MacBook without change the password? We have 60 Notebooks in our Network and can not change all the passwords.

Apple MacBook Pro 13" 2011 MC700D/A, Mac OS X (10.6.6), Model 2011

I have a similar problem. I have a home network with a dlink router. My iMac, MacAir and Ubuntu computer can all connect wirelessly, but my brandnew 15" MBPro times out and won't connect. I have no password on the wireless network, instead I use a MAC address filter. I know I have it set up right because I CAN connect to my network if I plug the new Macbook in with Ethernet.

I did use my new MB at a cafe wirelessly and it work flawlessly.

Any ideas on what I should do next?

Hi!

I bought a MacBook pro yesterday and I've similar problems. I cannot connect to my wifi :-( I'm using WPA-PSK-TKIP with a password that consists of 12 words and 1 number.

Every time I try to connect on MacBook it says "connection timed out" :-( However, I can connect my Windows notebook and iPhone without any problems. It's really frustrating; does anyone know what the problem is?

Best Regards

Hey All,

I bought my 2011 MacBookPro and cannot get it connected to my Verizon Mifi. It is using WPA2 encryption and I set the password to 1 uppercase letter, a few lowercase letters, and 1 number. It will not connect. My HP laptop sitting right next to it connected just fine and I can browse on it pretty fast. My iPhone 4s can also connect on it...so I don't know why I cannot connect to it. When I try to add this MacBook Pro, it sees the SSID, but when I enter the password.....it fails to connect and acts like I typed the wrong password in. My Verizon Mifi is the 4G LTE 4510L. I have not tried to update the firmware on the Mifi yet, but I am open to suggestions.....any ideas? I have connected many other devices to it.....but no MIFi! Please Help!

Do not use uppercase letters and it will work fine.

Apple laptops and WPA2 with password with uppercase letters won't work.
