I have had this problem since last friday but cannot solve it. I gave it a lot of thought so posting here is my last option/hope.
We recently aquired 5 new Cisco AIR-1602I-E-K9, I configured them all (almost identically) and they all connect to the same Cisco 4500.
However, for some reason they only work on some ports. I mean, for example, if I connect one of them to the port Gi1/40 @ Cisco 4500 it works, they also work at port Gi6/30, but they do not work at some other ports that has the same minimal configuration, for example Gi1/41, Gi1/43...etc.
The new AP's do turn ON when I connect them, but they do not spread the wifi and if I check the port at 4500 it is "down down".
Any tips/help would be much appreciated.
Thanks in advance and excuse my english.
