Ubuntu – There is a known bug for the wireless card for the Lenovo ThinkPad T440 running 12.04. What are the options


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?

  • The bug report you linked confirms that the driver is not included in Ubuntu 14.04. "Trusty: Confirmed." The driver can be compiled in 13.10, however it is unreliable: http://ubuntuforums.org/showthread.php?t=2206565&highlight=rtl8192ee I suggest you wait until a better driver is developed; check here and on ubuntuforums.org.

    Until that time, the advice above, to get a USB wireless, is sound.
