Few days ago I replaced Orange Funbox 6 with ONT LEOX LXT-010H-D
Configuration in Asus RT-AX88U done, internet connection established.
Every 30 minutes running spdMerlin.
With Funbox it is constant 630 Mb/s +/- 2-3 Mb/s
With ONT Leox in between 577 Mb/s and 630 Mb/s
Original MTU in Funbox is 1540.
In Asus it is possible to select MTU = 1500 max so I set this 1500 and the result is as mentioned: in between 577 Mb/s and 630 Mb/s
When I changed MTU to default 1492 results are even much worst: 380 - 560 Mb/s
Conclusion seems to be simple: MTU lower value = worst internet connection stability and speed.
Why there is a limit in MTU = 1500 in Asus MerlinWRT?
