Symptom
An alert with a "communication error" message in the Computer Status window appears when Using Apple Remote Desktop to observe or control client computers via a wireless connection.
Solution
A. If you are using Apple AirPort hardware:
1. Update the client computer's AirPort software to the latest version.
2. Using a computer that has the latest AirPort software installed, connect to the AirPort base station with the AirPort Admin Utility.
3. Update the base station software when prompted.
4. In the AirPort Admin Utility, configure the base station for a Base Station Density of "High", and set the multicast rate to 11 Mb.
You can get the latest software from Apple Software Downloads (
http://www.apple.com/swupdates/).
Note: Increasing the Base Station Density setting to High may decrease the usable distance between the wireless client and the access point (AirPort Base Station)
B. If you are using third-party 802.11 hardware:
Be sure that the client and base station software are both up to date. If you use AirPort client software to connect to a third-party base station, try using the latest AirPort software version. Consult third-party support resources for any questions regarding third-party software and compatibility.
Note: Wireless Internet access requires an Internet service provider (fees may apply) and AirPort (or AirPort-compatible) wireless Ethernet card and base station. Some ISPs are not compatible with AirPort. For more information, see technical document 106590: "
