It appears that I have a VxWare 1200 Aironet WAP. The Firmware version may be 5.02.03. The SN: is AMB0705M2UL. There are two others of the same age.
We VPN through the device. My research on Cisco www shows that there is a VxWare upgrade needed followed by an upgrade to an IOS (if I am understanding the situation).
My question is should I do this and why. Security for the device is acchieved by using the VPN tunnel.
From Vxwork to IOS can give you some features like:
Support of G radio, WPA and WPA 2 and much more.
Though I have seems VxWorks devices to be much more stable, so if security is not a concern and if you are happy with the basic wireless features you can stay with VxWorks.
