The Qualcomm Atheros 11G USB Wireless Network Adapter is a device that allows your computer to connect to wireless networks (Wi-Fi) through a USB connection. Qualcomm Atheros is a well-known manufacturer of networking hardware, and their wireless adapters are commonly used in laptops, desktops, and USB dongles to provide Wi-Fi connectivity.

The 11G in the name typically refers to support for the 802.11g wireless standard, which is an older Wi-Fi standard that operates on the 2.4 GHz frequency band. However, the adapter may also support newer standards (e.g., 802.11n or 802.11ac), depending on the model. This USB wireless adapter allows your computer to wirelessly connect to Wi-Fi networks, whether at home, work, or public places like cafes or libraries.
