BUYING GUIDE
WiFi 5 vs WiFi 6 USB Adapters
WiFi 6 adapters support MU-MIMO, OFDMA, and WPA3, delivering better performance in crowded networks. If your router supports WiFi 6, a WiFi 6 adapter will take full advantage. WiFi 5 adapters are still fine for basic browsing and streaming at a lower cost.

Internal Antenna vs External Antenna
Nano adapters with internal antennas are portable and unobtrusive but sacrifice range. External antenna adapters add bulk but deliver noticeably better signal strength through walls and at distance. Choose based on whether portability or performance matters more.
