Lenovo AR5B125 M.2 Wi-Fi Adapter

Replaces specific Lenovo part 11200354

This card replaces the original Lenovo part numbered 11200354 when that component fails or no longer meets network requirements. The upgrade is worth it when the existing adapter drops connections or cannot maintain the speeds your router provides.

Sustained operation in a laptop chassis

The adapter operates inside the thermal constraints of a laptop chassis without active cooling of its own. It maintains a stable link during extended transfers and long sessions rather than throttling after a short burst of activity.

Questions about this item

What M.2 slot keying does the Lenovo AR5B125 11200354 require for installation?

The adapter uses an M.2 form factor designed for laptop wireless slots; verify your motherboard has a compatible M.2 key before purchase.

Which screw size secures the 11200354 card to the motherboard standoff?
