Hello,

I have a Fritz!Box 7530 connected to a 50 MBit/s DSL line, which also creates a WLAN mesh using various Fritz!Box repeaters. Additionally, there is a NETGEAR switch connected to the Fritz!Box for home ethernet.

Now, there is 5G available in my area, with which I can reach speeds of up to 500 MBit/s (tried using an iPhone). So, I would like to primarily use 5G and fall back to DSL.

To achieve this, I would like to purchase a Fritz!Box 6850 5G and create a single network together with the FB 7530 DSL.

My idea would be:
- Use MikroTik hEX with DHCP enabled and with IP 192.168.178.1
- Put FB 6850 5G into port 1 with static IP 192.168.178.2
- Put FB 7530 DSL into port 2 with static IP 192.168.178.3
- Put NETGEAR Switch into port 3

Now, I'd like to configure the MT hEX to primarily route traffic of all devices in the entire network through gateway 192.168.178.2 (5G) and use 192.168.178.3 (DSL) only if 5G is offline for some reason (DSL as backup). However, my son's Xbox should always run through 192.168.178.3 (DSL) since DSL has lower latency for gaming.

How do I need to configure the MT hEX?
