wl_michael replied to Hervé's topic in Wireless and BluetoothFound a solution for the disconnection problem DW1520 (14e4,4353) on Dell E6x30 . I mounted the card in the port of the WWAN card. Works great and no more failures since them. This may also work on the E6x20. Only what is needed, MiniPCIe Adapter Half-Size to Full-Size.
