Define "best".
Keep up-to-date list of widely available devices which satisfy:
- ALL of the properties below:
- Available today in most parts of the world
- Fully supported by OpenWRT (working both 2.4 and 5 GHz WiFi, working NICs, working swconfig)
- Stable software for everyday use - can work for at least several months without restart
- More than 4/32
- Well defined support per hardware versions if there are more than one on the market
- As many as possible of the properties below:
- Easy initial flashing (software only). Mention other available options for those who are familiar with screwdriver/soldering/serial ports etc
- Relatively cheap - compared to similar devices
- Gigabit wired ports (although this is a dealbraker for me, some people might not require them)
- Working USB ports
- Working hardware offload
- Low power consumption
Such an example is good old Archer C7 v2, but it's getting a bit old.
