We have an ap 1242 access point. I am having two main problems with them. after installing them thorugh the use of the ACDC power plugged directly into them (IE no power inverter) they enetially configured and worked ok. But after leaving them un powered for a day they seem to loose the configuration and also are not recieving any ip information from DHCP. I initially configured it with an IP address of 192.168.32.201, was able to ping and configured ok. Since leaving it off it has lost all config, and also is not registering in DNS or DHCP so i am unable to find the ip address for it. can anyone help, have i not done something to save the config, or is this behaviour normal, is there an updatre IOS that needs to be installed?
