Hello, I got more and more issues with my router, it's an old WRT 1900 AC and before ditching it for a new router, I would like to try DDWRT or OpenWRT on it, custom firmwares save quite a few routers in my past so it's the last resort. Though, I don't know which custom firmware would be best for that router, any ideas? Or should I just skip that and go purchase an ASUS Wireless AX5700 or wait for Wifi7? Thanks!
