Hi friend.
Our forum main focuses on enterprise network products.
In an optimal environment with no interference and no block, the Wi-Fi signal's range is 100 meters.
During actual use, the Wi-Fi coverage range may be different from in the optimal environment, depending on the situation. Wi-Fi signals are strongest closer to Mobile WiFi. If there are physical barriers (such as walls, ceilings, and furniture) between devices and the Mobile WiFi, the Wi-Fi signal strength may be weakened. If this is the case, move your device closer to the Mobile WiFi.
Have a good day!
