I am trying to get wireless working on my Lenovo ThinkPad T440, running Ubuntu 12.04. I think I have a Realtek 818b wireless card.
$ lspci | grep -i Net 00:19.0 Ethernet controller: Intel Corporation Ethernet Connection I218-V (rev 04) 03:00.0 Network controller: Realtek Semiconductor Co., Ltd. Device 818b
It seems as if there is a known problem with the drivers for this wireless card.
What are my options for what to do next? Update to a newer version of Ubuntu? Wait for a bug fix? I am fairly new to open source. What are my options in this situation?
