Which wireless network disconnects from the internet, 2.4G or 5G? 

Which device disconnects from the internet? When it drops internet, does the internet LED on the AX73 still green? Who is your ISP?

If only the wireless connection drops on the router, it's suggested to run a Wi-Fi analyzer to review the wireless networks around you, then choose one with less interference by fixing the wireless channel, you can also change the channel width for the 2.4G to 20MHz, 5G to 40MHz, then monitor the connectivity.
