Wi-Fi dongle for the Rs 250?

Does anybody know what the rose rs 250 use for Wi-Fi antenna / reception. I assume it’s internal. The rs150 uses a Wi-Fi dongle antenna. Anybody know if this will work on the rs250m somehow and get a stronger Wi-Fi ???
Thank you

Hello @Aceofbase

I contacted the person in charge. The person in charge said that it is not recommended to connect the dongle to RS250. Like RS150, it does not bring a strong Wi-Fi signal, and the USB port is also lacking.

Thank you
