Hi there, OpenWRT Community & Devs
So, I've done my research and unfortunately only the TP-Link EX220 V1 is currently supported by OpenWRT, which seems to be much harder to get a hold of in my country. So I went with EX220 V2, whose QoS and Access Control features are literally broken, and on top of that, there's no official firmware support for it. I've been using it for almost 6 days now and I'll ship it out to any developer worldwide who's willing to have a go at it.
Thanks for stopping by and have a blessed day.
Collect boot messages at maximum log level and try to determine ram/flash/soc.
Add a link to OEM firmware downloads.
