Go to Device Manager, right-click the adapter, select Properties > Details, and choose "Hardware Ids." You are looking for a string like VEN_14E4&DEV_4311 .

This style is short, punchy, and visual. Best used with a screenshot of your "Network Utilities" showing the adapter active.

Use the open-source utility LegacyUpdate or Snappy Driver Installer Origin (SDIO) – both include community-patched Broadcom 802.11g driver packages that are digitally fingerprinted for safety.

Right-click the adapter in and select Update driver .
