I recently got a Lenovo ThinkPad L440 and the wifi drivers seems to be broken.
I am using Ubuntu 13.10
Relevant output of
00:19.0 Ethernet controller : Intel Corporation Ethernet Connection I217-V [8086:153b] (rev 05) 02:00.0 Network controller : Realtek Semiconductor Co., Ltd. Device [10ec:818b] 08:00.0 Unassigned class [ff00]: Realtek Semiconductor Co., Ltd. Device [10ec:5227] (rev 01)
I tried the steps mentioned here, but had no luck with it.
Any way to get the wifi working.
