We installed Cisco 1252 APs in our classrooms over the summer. The Cisco 1252 are running in autonomous mode and are fitted with dual radios (2.4ghz, 5ghz).
What we have been seeing is that after a given time an 1252 AP will not give clients on the 2.4ghz radio ip addresses. The clients on the 5ghz radio don't have a problem. The AP will continue to associate and authenticate users on both radios but users on the 2.4ghz radio looses the ability to reach the network. A reboot fixes the problem for maybe a day or two. This is an output of the association table on an AP that is having a problem. We are running version 12.4(10b)JA1 of the firmware: Any ideas? 802.11 Client Stations on Dot11Radio1: SSID [SecureHastings] : MAC Address IP address Device Name Parent State 001c.b3b8.a1f7 192.168.34.219 unknown - self EAP-Assoc 001c.b3b9.c835 192.168.32.234 ccx-client - self EAP-Assoc 001f.5bbe.823e 192.168.33.198 unknown - self EAP-Assoc 0023.1205.4488 192.168.33.79 unknown - self EAP-Assoc 0023.1255.1f17 192.168.35.152 unknown - self EAP-Assoc SSID [hastings] : MAC Address IP address Device Name Parent State 001f.5bbc.d58c 192.168.14.189 unknown - self Assoc 001f.5bbc.e60d 192.168.10.139 unknown - self Assoc 0022.6890.b7f1 192.168.9.218 unknown - self Assoc 0022.6980.5d0c 192.168.15.159 unknown - self Assoc 0023.1201.4ed6 192.168.14.140 unknown - self Assoc 0023.6c84.6aeb 192.168.13.211 unknown - self Assoc 802.11 Client Stations on Dot11Radio0: SSID [SecureHastings] : MAC Address IP address Device Name Parent State 0021.006a.d366 0.0.0.0 unknown - self EAP-Assoc SSID [hastings] : MAC Address IP address Device Name Parent State 0013.e87d.2425 0.0.0.0 ccx-client 198-3rd-RmK self Assoc 001a.73bd.1ba9 169.254.126.12 unknown - self Assoc 001c.bf6b.b904 169.254.202.5 ccx-client 198-3rd-RmK self Assoc 0023.4d64.56b6 0.0.0.0 ccx-client CherylL self Assoc 0025.5621.88db 0.0.0.0 ccx-client BCARR self Assoc ---- Nicholas Urrea Information Technology UC Hastings College of the Law [email protected] x4718 ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/.
