I upgraded our Cisco Wireless LAN Controller 4402 that has (8) 1100 series APs.
The first upgrade to 4.2.x.x went fine.
However, the upgrade to software version 188.8.131.52 and Boot to 184.108.40.206 seems to now no longer be able to connect to the 8 access points. I am perplexed as to what to do next. The APs are all Power over Ethernet and seem to be working fine.
