Thanks again for the helpful information. In the meantime, I have contacted the company that installed and set up this WLAN System bevore some years. I said we would like to add some new R510 to the system and an update of the software for the ZoneDirector. (So that the R510 also works on it) Now the company has me and said that only one R600 is still possible for our system. Because you can update our ZoneDirector only up to software version 9.10.2.0.76. Higher versions are not offered by the manufacturer, we were told. Maybe someone has information, if that's really true? Thank you again in advance. Here are some more data from our ZoneDirector:
Version: 9.8.2.0 build 15
Modell: ZD 1106
Systemname: ZD 1125
Accesspoints: 25
