Need advice in this probe. Our campus internal wireless system is working fine until weeks ago this issue occurred.
Our campus is running on LWAPP AP1242, WISM ver 5.1, and external Radius server using 802.1x.
Client will authenticate to the SSID via 802.1x ext server that is compliment with WLC. The client around certain APs had a problem to authenticate even the signal of the SSID was so strong. The user had register to the radius server and they had succesful connected to others AP before with same system.
This certain APs were random, each day more than hours it fail to establish connection to the SSID. After several hours, it is back to normal( working fine). For those APs that suspected, i had change to totally new AP assuming that the previous had a hardware prob. But it keep happen to the new AP that been install.
Then i suspected that external radius might be the reason, so i configure one SSID with open access for that AP. But i fail to connect the SSID with open access during the problem. After hours it then successful connected to open access.
Why this suddenly happen? It is all working fine, and suddenly this occured. If this because of the rouge AP jamming signal? configuration? SSIDs brodcast? Firmware issue?
