We're running 7.6 with a mix of APs including 3602s, no reports of this issue here and I've not noticed it on my Macbook Pro. Though it could always be some setting we don't have in common such as different encryption types, QoS, or HA that are causing the issue.

Happy to drill down into the nitty gritty off list if you want to check configs, drop me a line.

Has anyone else seen a dropped connection issue with Macbooks and Cisco WLC v 7.6.100.0 code?

 

We are pilot testing 7.6.100.0 code on a WiSM2 card supporting staff APs and have noticed a dropped connection issue with Macbooks when associated with the 5GHz radio on model 3602i or 3702i APs.

 

The connection typically fails after approx. 15 minutes, usually leaving the client with an IP addr which it can ping, but the client cannot ping the gw addr or anything beyond the gw. The client WiFi interface reports that it is still associated, which is confirmed on the controller side of the connection.

 

For one Macbook the test AP is directly above the laptop, with a 5GHz-specific and AP-specific SSID to help isolate the issue.

 

IOS and Windows7 platforms do not appear to have the issue when associated to the same SSID on the same AP.

 

But so far three Macbooks (two Macbook Air with dot11ac, one Macbook Pro with dot11n) have demonstrated the dropped connection issue. They are all running Mac OS X 10.9.x (Mavericks).

 

The issue does not occur when the test 3602i AP is moved back to 7.4 code.

 

Thanks,
