At the moment we got 9 APs connected with one Switch. With the Application "APDiscoverTool" none is shown. The problem consists since the upgrade to version 5.5.
All APs with the version 5.X are working fine. 9 APs, which are lying right before, seem to have an older verion. (Mfg. Date 29SEP10)
I configured the IP like it is described in the Link -> 168.254.166.2 // MAC address was the : A61C -> 166.28
Still no APs is found.
