Thinkpad T540p Wireless Adapter Support

[snietfeld]

Wireless adapter isn't showing up (just eth0 and lo when running ifconfig -a).
Running fresh install of Ubuntu 12.04.3.

Wireless adapter listed as "ThinkPad Wireless 2 x 2 BGN with Bluetooth" on Lenovo website.

Result of running lspci -nn | grep 0280:
04:00.0 Network controller [-0280]: Realtek Semiconductor Co., Ltd. Device [10ec:818b]

Reading online it sounds like Linux support for Realtek devices is poor.
Tried installing the r8168 drivers from here, but no luck (adapter still doesn't show up after running ifconfig -a).
Found a similar thread for the Thinkpad 440p, which indicates that no drivers exist yet and lead to this Ubuntu bug report, which is tagged as incomplete.

Is there anything else I can try, or should I send it back and get one of the other wireless adapters (listed below)?
- Intel Single Band Wireless 7260BN with Bluetooth 4.0
- Intel Dual Band Wireless 7260AC with Bluetooth 4.0

I'm fairly confident that the 7260 devices will work in 13.10 and can be made to work in earlier versions: http://askubuntu.com/questions/32251...dvanced-n-7260
