Been having some trouble today with wireless access....
My router is set with WPA2 security, Wireless MAC Filter for Wi-fi devices and hidden SSID....all been connecting and working fine for weeks until today.
Only thing showing connect was my Mac Mini via ethernet cable. No Wifi enabled device would connect to the router at all, but been working fine before today

I have had to change the network name and password for the devices to re-connect to the router, but ONLY when the SSID is not hidden. If I try and connect to it with the SSID hidden the mobile, tablet etc cannot connect to the router unless I un-hide the SSID, then connect and then hide it.
Not sure whats going on, anyone else had any problems?
Thanks
