for neophytes only
The MR6350 on the technical sheet corresponded completely to what I was looking for, unfortunately the reality is far from my expectations. First of all, the impossibility of configuring the router via a web interface, without being prohibitive it is a big disadvantage, and even if the proposed application allowed a real control of the network, but it is not the case. It's not possible to disable the dhcp server, it's not possible to prevent ARP requests from being sent en masse to make itself the default gateway (in another context this is called an ARP Poisoning attack), it creates problems on the rest of my network.
In short, for users who don't have a specific topology and are just looking to extend their wi-fi coverage, it might do the job, but even then, it would be a fluke.
Wanting to do routing with a router, what a strange idea, and yet it is impossible...
