Not mantaining the 2,5 Gbps.
I can use my own router, but they will cap me at 1 Gbps.
For example if all their ethernet ports are 1 gig, they have effectively capped your max download to 1 gig.
If they had an ethernet port putting out 2.5 gig, then I would say get the AX3 or better.
That vodafone station doesnt look like the white ones on the net, what is the model and name of ISP provider.
These are the specs of the Vodafone Station Wifi 6:

Anyway I can reach 1800 mbps download on my phone using Wifi or downloading from 3 of the interfaces simultaneously… that is exactly what I want to do with Mikrotik (this morning I bought the Hap AX3 
)
