It seems the cable might have failed, stopping the automatic link negotiation. Your device could be using another negotiation approach. There aren’t any settings visible in your screenshots to adjust the link speed.
I attempted to swap in another router, but it now functions partially. However, the speed is limited to 100mb due to the older middle router. The current setup looks like Modem → DIR1253 → Old cable → DIR612 → New cable → SBG6580. I’m considering giving up since replacing cables would be very time-consuming. Thanks to everyone.
