For future clarity, WiFi adapters marketed at 150Mbit often only achieve that speed with a 40Mhz channel width because they lack MIMO support. At a standard 20Mhz width, around 72.2Mbit is accurate. Moreover, the default drivers typically detect only 2.4Ghz; if your router operates on 5Ghz, consider changing the SSID to identify the adapter correctly and override the default choice that usually favors 2.4Ghz due to its stronger but slower signal. If it still doesn’t recognize 5Ghz, search for updated drivers online instead of relying on Windows’ built-in options. Wired connections remain the optimal solution, making your selection a fortunate one.
