Hello,
If you need a 5G connection, I'd recommend the X3000.
Since Mango only offers 2.4G WiFi and 100Mbps LAN, it can't full up to 5G cellular speed.
A USB 5G modem attached to Beryl AX might not be cheap either.
USB modem probably not strong compatible, and the USB port or cable touches by hand causing the network to reconnect, and the experience can be unpleasant.
