Product Description
The IBM 39T0077 is an internal wireless network adapter designed to bring Wi-Fi connectivity to compatible IBM ThinkPad laptop models. Adhering to the IEEE 802.11b and 802.11g standards, this card operates in the 2.4 GHz frequency band, offering wireless data transfer rates of up to 11 Mbps for 802.11b and up to 54 Mbps for 802.11g.
