Wireless Network with more then 70 AP (AIR-LAP1242G-E-K9 and AIR-LAP1142N-E-K9).
About 200 WireLess clients (PC, Cisco-Phone, Vehicle-Mounted Computers, etc.) on several WLANs.
All managed by 3 WLC (4404 - 126.96.36.199) and WCS (188.8.131.52).
The IOS of the AP is 12.4(18a)JA2.
I have a problem with some OLD Vehicle-Mounted Computers.
This are LXE VX1, only 802/1b (only 1Mb/s), no WPA, only MAC authentication.
I am not able to associate this clients, even if disabling MAC-authentication (all open).
Looking on the WCS, I don't see events related to this clients, no entry in LOGs, no entry in Monitor -> clients -> probing Clients.
Some "incompatibility" on Radio?
But the clients are OK: with a stand-alone AP (AIR-AP1242AG-E-K9 - 12.4(10b)JDA) they can associate (different SSID, of course).
The client has very few parameters: SSID, ecc.
Some idea ?
