Macbooks dropping when doing high throughput
« on: December 19, 2013, 11:19:14 AM »
I have a customer that has a mix of Windows PCs and Macbooks in their environment.  The WLAN is RFS7000s on WiNG 4 code and AP650s. (We cannot currently migrate to WiNG5).  The Windows PC have no issues, but the Macbooks drop when ever they do anything requiring high throughput - HD video, large file transfers, etc.  They believe is is the WLAN infrastructure since their Macbooks "work everywhere else".  I, of course, believe it is something specific to the Macbooks - possibly an Apple proprietary tweak on an IEEE standard that is causing the issue.  The controller logs all show some form of client disassociation - reason code 2 (datapath requested deauthentication) or Code 3 or Code 8 - both are the clients leaving the BSS.

Anyone ever run into issues with Macbooks on their WLAN?

well basics for any iOS device:

WMM must be turned on, Apple enforces its devices to support only WMM (their AirPort WiFi points do not even have the option to disable WMM). As far as I know WMM is disabled by default on WiNG 4.
SSID must not be hidden.

Power save, Apple is pushing their devices to the edge, when you talk about power-save, so UAPSD should be enabled (default on WiNG 5, not sure about WiNG4).

Hope this helps!
