Aften disconects macbooks from Wi-Fi

Our team use Macbooks for collaboration with client via software tool. All laptops connected to internet via access point (Wi-Fi) vendor Cisco.

But all members faced issue -from time to time their laptops disconnecting from Wifi. After few seconds laptop connected to the same Wi-Fi.

Logs in access point shows these disconnecting but problems on access point we didnt find. Replacing access point (Wi-Fi) doesnt help.

This problem we see only with Macbooks based on OS X. Laptops based on windows works fine.

List of latops which have a problem:

Hardware model: MacBookPro11,3OS Version: 10.10.1 (Build 14B25)
