These differences mean that generic drivers for other Realtek 802.11n USB chips will not work. You must obtain a driver that explicitly supports the 8188GU (or 8710BU).
For modern Windows users, this adapter is often "plug and play," but manual updates are frequently needed for stability on Windows 10 and 11.
