how can I connect an external hdd/flash storage thru usb-c port of sagemcom TMobile home internet gateway to be accessed wirelessly in home by wifi?

Routers can be connected to the gateway either wirelessly or by ethernet cable. Typically, ethernet is preferred. The USB port on the gateway can provide 5V power to a device, and it is often used by those who use a 5v cooling fan to help cool the gateway, when they are having overheating problems with their gateways.

@Hpanda, one cannot access an external hard drive or flash drive connected to the USB-C port on any of the TMO HI 5G gateways.  If you have a router connected to your gateway, you would be able to wirelessly access a HDD plugged in the USB port.  The USB port on the gateway can be used as a power source (say, for a small fan to cool the gateway).

Not clear.   'router connected to Gateway via what?  …. USB port on gateway as power source…?  But there is only one vacant USB C port; the lower one is for power.
