Client hang when using enable radio management support
WLC version 184.108.40.206
When the client (mainly XP SP2) using IntelProSet connects to the wifi, the client hangs and requires power down. The radio management support has been enabled for sometime and the problem just happened from few weeks ago. No configuration change in WLC and the Wintel team says there was no patch installed.
If the radio management support is disabled, there is no hanging issue.
Re: Client hang when using enable radio management support
So Intel's troubleshooting document says that you need to turn off Radio Management from the Access Point (but it does not say what to do from here). So it sounds like they say to just turn it off to resolve your problem.
My question however, when you say with radio management off, the problem goes away. So are you turning radio management off from the client level or are you turning it off from the controller?
Also, is it every client that has a problem? Or every Intel Client? Or is it every client with CCX turned on, or every Intel client with CCX on?
Or is it by chance, just one client that happens to have its CCX setting different that other clients?
Long story short, not that I've had this problem before, but when I called TAC on other radio feature problems before, they've always said one of two things: 1) Upgrade the client drivers. 2) disable the feature.
(or maybe it is a real bug).
So if you really need CCX radio management and the problem is effecting all of the clients, it may be time to open a TAC bug report.
I don't know which CCX version it is. It is using latest Intel ProSet and driver version.
I do have some other Dell notebooks (totally different model, driver and Intel Proset version) using Intel wireless module and not suffer from the CCX issue. I think it is just naming issue in the CCX compatibility table, the wireless module is equivalent in some sense.
