Hello,
i have an Intel Wifi Link 5300 AGN installed in a Dell Precision Laptop M4300. Os is Win7 Prof 64Bit, Driver Version 14.3.0.6 and ProSet-Version 14.3.0.0.
When I have an active Lan-Connection and no active WLAN-Connaction and try to activate My Wifi Technology I get the following error-message:
in german:
---------------------------
Intel® My WiFi Utility
---------------------------
Die Intel® My WiFi Technologie konnte nicht aktiviert werden, da der Wireless-Adapter über einen nicht unterstützten Kanal an den Zugriffspunkt angeschlossen ist.
in english - my best translation I can offer to you.... 
---------------------------
Intel® My WiFi Utility
---------------------------
The Intel ® My WiFi technology could not be activated because the wireless adapter is connected to the access point via an unsupported channel .
I have no idea, what this means and what to do. Any help will be apreciated 
Regards,
chapolote
