iPhone losses WIFI connection

[gwdower]

I have my wireless network at home set up with the ESSID setting disabled so that the name of my network isn't broadcast publicly. I currently have multiple iPhones, iPods etc., all set-up to connect to this network. For some reason, one of the devices will not maintain the connection when the ESSID is disabled. When the setting is enabled, the iPhone will find, connect, and maintain the connection, however once the ESSID setting is switched back to disabled the iPhone 4s losses it's connection and can't reconnect.
Any way to resolve this issue without a restore?

Thanks for your suggestions/assistance.

I'm having the same issue with my iPhone 4, but maybe slightly different. I can connect to my hidden network, but occasionally it looses its connection and I have to manually re enter the network SSID and security key. Then it's fine until the next time. Seems to do it every couple weeks.
