Hi Everyone..
We have Cisco Aironet 1240AG Wireless AP's in out network. Now, we have some PC's, laptops and mobile phones connected with with this AP and all devices are working fine.
Now suddenly from today when I am trying to associate some new devices to the AP it is not working means the devices are not associating.
Please help.
