Authentication problems with Nexus 7

Hello,

I'm the Stake Technology specialist and have receive some compliants of late from Nexus 7 users
who can log in to the wifi due to authentication issues.
People around them have no problem connecting with other devices.
I've rebooted the firewalls and aps and can connect with my android device (cel phone).
Anyone have any suggestions?

Any help will be apprecited.

I didn't find the right solution from the Internet.
