Re: Wi-Fi Scanning and excluding 802.11n 5Ghz networks

Are you sure the first one is not a repeater (airport express, time capsule)? Have you actually tried to connect the esp32 to the second one by specifying the bssid? As you can see the 2.4ghz and 5ghz networks are not supposed to share the same bssid aka Mac address, but they are usually similar. ht...
