wifi network saved but not connecting

[jme]

Z2 has work perfectly for months on our work wifi network. One day came up with msg wifi networks available, clicked on it, clicked to connect to saved network, and just says saved and doesn't connect.
Tried forgetting and reconnecting
Tried restarts
Defiantly isn't the router as others are connected
Is this a fault where my phone will need to be sent back?

Thanks, but none of those ideas seem to work any other ideas for a technology challenged person?
