There has been an issue with our wireless connection dropping. One of the troubleshooting solutions has been a suggestion to update the firmware on our ZoleDirector (which in turn updates the APs). The model is ZD1106 and the Version listed (which I'm assuming is the Firmware version) is 220.127.116.11 build 110. What's the proceduce to do this? Where exactly can I find the correct firmware download? Are there any updates before the latest versiont hat I have to install first?
