Notebook Wi-Fi Adapter for Legacy Mini PCI Slots
This Intel PRO/Wireless 2100 module adds 802.11b wireless networking to notebooks that accept a Mini PCI Type III card. It is intended for repairing or upgrading older laptops where the original wireless hardware has failed or is missing. The adapter fits internally and connects directly to the system board through the Mini PCI interface.
11 Mbit/s Throughput on the 2.4 GHz Band
The adapter operates on the ISM band with a maximum frequency of 2.50 GHz and delivers a wireless transmission speed of 11 Mbit/s. Indoor antenna range reaches 300 ft while outdoor range extends to 1500 ft. The UNII band is not supported, so 5 GHz networks cannot be used. Performance is limited to the 802.11b standard.
Slim Type 3B Form Factor for Thin Chassis
The card measures 1.8" by 2.4" with a depth of .2" and weighs approximately .42 oz. This thin profile is designed for notebook systems where overall thickness must be kept to an absolute minimum. Buyers needing 802.11g, 802.11n or modern WPA3 security should look elsewhere as this hardware does not support those protocols.

Questions about this item
Will the Mini PCI Type III interface fit the slot in my older notebook?
The adapter uses a Mini PCI Type III host interface measuring 1.8 by 2.4 by .2 inches, matching the Type 3B slot found in many period notebooks.
How can I confirm the 11 Mbit/s link is active after installation?
The driver reports the 802.11b connection speed and shows signal strength within the 300 ft indoor or 1500 ft outdoor range.
Does the WM3B2100 package include antennas or must I source them separately?
The module weighs .42 oz and supplies only the internal Mini PCI card; notebook antenna cables are required but not included.
