It did work out - and just in the nick of time! My main router, a Cudy, was glitching badly; I took it apart yesterday and found a bulging capacitor about to burst. So I flashed my old Linksys with the latest OpenWrt - it was so effortless that I wasn't sure I configured it properly! Even though it's an older WiFi 5 model, speedtests show no measurable drop in performance. Interestingly, packet latency is half of the Cudy's, so it feels much snappier and responsive. It honestly feels like an upgrade lol. I love the app store it has too, very useful. Thank you very much for the recommendation!
