Question about Acer Hotspot Connect M5

A repeater should theoretically not be a problem, but the WLAN on the device is very poor. It has about 10% packet loss. It only works well via cable (via the Ethernet port). I recommend deactivating the WLAN and connecting a separate WLAN router to the Ethernet port. The WLAN repeater can then also be operated together with the separate WLAN router.
