Anyone have any thoughts on BannanaPi routers? Pros, cons, better alternatives? How hard is it to turn an x86 computer into a solid multi-band wifi router? Is it just a matter of installing openwrt & buying some usb3 wifi dongles or is that a ridiculous question? #asknostr
You might check out @Jameson Lopp blog. I remember he had a post about building his own router. I don' remember how applicable it is!
Not sure if OpenWRT runs on x86 but I found OPNSense rather user friendly. Related: https://blog.lopp.net/how-to-protect-your-home-network-with-a-gigabit-vpn/
