Whay to use only channel 108 for backhaul

I can see that my Orbi system is always using channel 108 for the backhaul network.

I have a neighbour who also has an Orbi system and I can see that his system also uses channel 108 for backhaul and I see that his signals are quite strong at my house (RSSI -71 and -80 dBm).

I'm sure that our networks are distrubing each other and I think this is one of the issues that makes my backhaul not stable.

It should be wise that Orbi either automatically chooses a free channel (there are many other unused channels to choose from!!!) or let us choose a channel (probably not allowed to be selectable in Europe).
