for the vlan, 2 Access points is good for me,
I don't know yet for the use, maybe a point with vpn, or special home automation, I don't know yet, but currently, I connect to a wifi hotspot, and I redistribute with a new ssid on my internal network
You might as well get another mvebu board without wireless (like the APUs are x86_64, without wireless), Marvell WiFi is dead in the water at the moment and no improvements in sight. Frankly, none of the AC WRT series are interesting anymore if you need wireless.
You are not sure about your future network, but include a detailed diagram.
Does this diagram show someone else's network?
no, is my exemple diagram, i think after, on my futur home, install one or two camera and NAS ( synologie i think )
after, the wifi mesh is possible whit "orbi" for exemple
I do not really know my needs, but I try to see to be quiet for a few years.
on my current TPlink, I am fine, but it is a 300mbps, and it is sorely lacking in space, I would like to have fine management of connections as well as adblock support and several other functions offered by OPENWRT ...
it's not easy, and currently, I don't have a supplier, but I go through a hotspot with a speed of 6mbps ^^
but eventually, when I take a supplier, and the fiber will be in my village, it will be necessary that the switch follow the connection.
With those prospects it doesn't make sense to overbudget your router with 1 GBit/s capability in mind at all - availability and price delta are simply prohibitive. Yes, do engineer your local network with sufficient headroom, maybe even look at wireless 'mesh' systems (do prefer wired backhauls, if at all possible) if that floats your boat, but for the routing tasks a sub ~50 EUR dual-band router will do a good job, until you actually get >>200 MBit/s WAN speeds at your location.
I revise my ambitions downwards, so I am looking for a max router 100 € with good wifi performance, for me, good performance is good wifi in 2.4ghz to make an AP relay as well as 5ghz with mini 800mbps
3 rj45 + flash port to install apps (adblock or privoxy + other things)
I don't care about IPv6, even if it goes hand in hand, this one will be deactivated
Personally I think that the RockPro64 board has a lot more potential than the aging APU boards however OpenWrt's SBC support is quite poor so you need to look elsewhere if you want to use RK3399 or a similar board. This would however most likely require you to get another box for handling wifi unless you're willing to use USB adapters which may or may not be a great idea.
