After upgrading autonomous AP to Lightweight, all Dell E5500 and E4300 laptops are dropping their wireless connection frequently.
This happens only when Dell Connection Manager running. Works fine with Windows wireless zero configuration.
Customer tried WPA and even no security with the same result.
Dell support has no solution except reinstalling the software, that didn't help.
I wonder if anyone has seen this before or has any suggestions (other than removing the Dell connection Manager).
