Macbook Pro wifi invalid password problem

Have a strange problem with my MacBook wifi connection in that everytime I connect my MacBook Pro to the wifi router it requires a WPA2 password. I type in the password to join only to be told it is an invalid password, however, if I keep repeatedly clicking on the submit button (between 3 and 11 times) it eventually accepts the password and connects to the wifi - I've tried deleting the network and then adding, have deleted the password and reentered it in the keychain.

If I put the MacBook to sleep for any length of time then restart it, once again it forgets the password and I have to go through the whole ritual again.

I'm not having any problems with my iPad, iPhone and recently purchased Nexus 7 (sorry Apple but I need StreetView & YouTube) which all automatically connect.

This issue has been going on for months now. As for OS Lion, well it was running 10.7.4 but I updated it today to 10.7.5 to see if that fixes the problem but it's had no effect.

The MacBook connects flawlessly at home so am not sure what is causing the grief.

Anyone have a clue what is causing this and how to fix it.

Hey everyone. about 2 years later, I am having this problem. all the usual stuff with deleting network, rebooting and etc didn't work. any other suggestions out there? my machine costs £1800 and it is not able to do such a basic thing? Apple you disappoint me! Cheers for any help!

I'm pretty certain the problem is with the Home Hub 5. I upgraded my broad band to fibre optic and a HH5 was supplied as part of that. As soon as the new HH5 was installed my airport time capsule (ATC) refused to work. After Apple support trying very hard to fix it the ATC was returned suspecting it needed repair. Whilst it was away and I was running wi fi on the HH5 my Mac Air kept on losing its wi fi connection. That was eventually fixed by Apple support providing a link to a BT forum where it suggests putting the HH5 5ghz output onto a separate channel and just using the 2.4ghz. The link is

The ATC was replaced and when this new bit of kit set up it could not talk to the HH5, like its predecessor and thus unable to provide internet access.

By deduction the introduction of the HH5 is the cause of the problem, Apple are still working on it and I cannot speak highly enough of their service and attempts to fix the problem.

This was driving me insane. Making separate network names helped. Thank you!!

This helped me. Thank you! We have a BT HUB5. I'm the only Mac user in the house. All was fine. We were running on 2.4 only. My husband had re-enabled 5, in sync with 2.4, which I didn't know until I read this post & asked him if it might fix my wifi connection problem. Thank you very much. Stress over!

hello!

i am trying to free storage space by removing useless stuff

i have a password problem when attempting to erase a corrupt application ( RSS bot )

it refuses my password which works fine in other cases ...

i have tried to click help to find a solution or reset the password but it does not work

i had to go online and search reset password then i only get other cases for wifi password problems

i wish to remove all passwords in all cases

its so time consuming to keep entering passwords for absolutely everything

i do not have anything to hide and feel that passwords make lifer harder and serve no purpose

thank you for your help
