If you're running a homelab IDK why you wouldn't just dump the GL firmware & flash pure. Eat any downgrade in performance in exchange for full flexibity instead of the pseudo-OpenWrt & stale repo, kernel GL builds on. You already know wired is always going to outperform Wi-Fi. Their firmware is a hindrance to someone like you.
Drop the Argon theme on it if you don't like stock LuCI. The GL GUI only makes sense for SOHO & travel users.
