One stupid question. If I have a 1x1 card and then I want to install а 2x2 card. Do I have to change antennas, too or I just install a new 2x2 card and that is it? Thank you in advance

Some Thinkpads had the antenna for BlueTooth installed and the cable is not connected so simply install and connect the WiFi and BT antenna and youa re good.

However, many Thinkpads do not have the antenna and cable installed. My T61 and others I have worked on required the screen bezel be removed to install the hardware.

The exact model of the laptop might get a definitive answer.
