According to the Lenovo product page, the device has an RJ45 connector which enables the connection of a LAN cable.
Alternatively, there are USB WLAN adapters with which you can equip a device without WLAN with WLAN.
In addition, according to the product page, the device has Wi-Fi:

In the technical data there's the point WI-FI with the entry ThinkPad® Wireless 2x2 BGN + BT 4.0
which means, your laptop supports WLAN in the modes 802.11b / g / n
Does that mean that I need an adapter to receive Wi-Fi?
OK. Super.

The device mentioned is already equipped with WLAN as standard.
