We also tried..it will go into sleep mode while some tasks are still running, thus disconnects, run the command alone to keep it awake no matter what. See if this helps the disconnect issue you are having.
caffeinate -u -t 3600 3600 in the above command is the number of seconds to keep the system awake. What's interesting is that you can effectively set your Mac to shut down at a specific time (that is, the built-in sleep mechanism will start counting when that time runs out). You can also run the command alone to keep your Mac awake until you stop it by pressing Control-C.

We found that IPv6 was on by default. The theory is, it would try to get an IPv6 DHCP first, timeout, grab an IPv4, then retry IPv6. In doing so, disconnect. >From Terminal, networksetup -setv6off Wi-Fi Disconnects are a major problem with OSX 10.5 and above...just read the forums on Apples site.

We are an Aruba deployment (M3 controllers and AP-105s/125s). For the past 3 weeks we have seen a high amount of disconnections where about 90% have been tracked Apple notebooks with the latest OS versions. I'd be grateful to hear if anyone one is having, of has had the same issue recently, and any possible recommendations to address the issues. ________________________________ HERNAN LONDONO Associate CIO Barry University ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/. ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/. ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/. ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/.
