❓ WHEN TO REPLACE THE WWAN MODEM?

• No connection to the cellular network – laptop does not detect GSM networks despite a correctly installed SIM card
• Frequent disconnections – issues with data transmission stability
• Slow transfers – significantly reduced data transfer speed
• Error messages – the operating system reports issues with the WWAN module
• Functionality expansion – desire to add cellular network capabilities to a laptop that was not originally equipped with a modem

🔧 INSTALLATION PROCESS

Installing the WWAN modem in ThinkPad laptops is relatively straightforward but requires caution. Before starting the installation, the device should be turned off, unplugged, and the battery removed. Next, identify the M.2 slot designated for the WWAN module, usually located under the service cover on the bottom of the laptop. The modem should be gently inserted at a 30-degree angle, then pressed down and secured with a mounting screw. It is also necessary to connect the antenna wires, which are usually color-coded. After closing the casing and turning on the laptop, the system should automatically detect the new device.
