Hardware Version :

Firmware Version :

We have AC1750 in our office working only in 5Ghz band. For the last month the WiFi network keeps going down at least few times per day, requiring us to reboot the router in order to get it back. Is this behaviour expected? How can we fix it?

Upgrade the FW to version 18 ( appears you are still on 15 (150617) )

there are known issues with the Qualcomm chipset in some Laptops (Killer Networks ) that can cause this , see the sticky thread at the top of the Forum

QCA6174x chipset AC Wifi Adapter or QCA6174 chipset AC Wifi Adapter ...use Driver version 12.0.0.448 and FW 18 if possible.
