Hello, I am looking for a laptop with the following specs: Built-in GSM module Trusted platform module Support for these modules, as for the network (Ethernet + WiFi) for RHEL/Centos6. I tested Lenovo W540, and the WiFi is not detected. lspci shows: 03:00.0 Network controller: Realtek Semiconductor Co., Ltd. Device 818b I came across http://askubuntu.com/questions/376732/thinkpad-t440p-wireless-network-controller, so it turns out, this WiFi card is not supported (yet). So, if anyone can recommend a working solution, please contact me, either here or off the list. Thanks in advance,
