My school's and district's Cisco 1142Ns continuously (every 8-10 minutes) drops the wifi connection with MacBook Pros and MacBook Airs running the newest OS, 10.9.4. In order to reestablish the wifi on those computers when the wifi drops, we have to either manually turn the wifi off then on or renew the DHCP lease. Either way reestablishes the wifi immediately, until it loses it again.
In talking with one of Apple's senior product specialists, I was told that higher versions of Mac OS don't work well with WEP encryption, to try WPA2. I was able today to try WPA2 at work today and the same issue persists. I wish it had been that easy.
I also have a MacBook running OS 9.7.5 and it has no problems staying connected to the network as do others at work who are running earlier OS versions.
What can I respectfully suggest to my school's and district's IT departments in order to get the problem fixed or narrow down the possible reasons? I am assuming their is a function or functions in the router that will enable the communication between the access points and laptops to remain "on" and to not drop.
