The Banana Pi is easy to get going, simply download the image and flash on a SD card. We’re talking about a vendor that actively supports OpenWrt after all.

There are other devices supported by OpenWrt and this might interest you. Checkout the tables. There are also tons of Commercial routers / AP that are supported by OpenWrt and will provide a good experience but you’ve to pick them very carefully.

About range it mostly boils down to the WiFi chip manufacturer and if you want open software or not. It boils down to: the devices with the most range and speed are usually powered by Broadcom (Ubiquiti and whatnot) but you don’t have OpenWrt for those chips because they don’t provide open-source drives. MediaTek and Atheros are very open-source friendly and they perform well but Broadcom is Broadcom.

I’ve been running OpenWrt and DD-WRT (supports older routers some with Broadcom chips) for about a decade now and I don’t see me going back to bullshit vendors and their cloud stuff. I even deploy those on customers (usually small offices 10-50 people) and they’re happy with them as well. The Banana Pi BPI-R3 is my main router / AP and I’m very happy with it, more CPU and RAM than required for sure. I also deployed one at a customer and it runs flawlessly. Whenever the R4 is released I’ll deploy one to another customer who’s currently running a bit short as their current router is having trouble with more than 10 or 15 VPN clients connected at the same time.
