The router fails to recognize the Ethernet cable, while the computer successfully connects.
I attempted to acquire a different cable, but it turned out that the one I got was causing unusual behavior with the router.
It looks like you were worried about a problem but didn’t test the cable first. It seems counterintuitive that your computer works while yours don’t, even though you thought it would be obvious.
I received it directly from the store, likely in its original wrapping. There were no signs of any issues. The length is approximately 30 meters—about five meters more than the cable I replaced, which still functions properly. I thought the length shouldn’t be a factor, but I’m not sure if that’s correct. Another point to consider is that when I tried connecting the possibly damaged cable to my laptop, it would sometimes appear and disappear every few seconds. In short, the cable works fine on my desktop but seems to behave strangely with other devices. I’m trying to figure out why only my desktop recognizes it while everything else doesn’t. Appreciate your feedback!
It's clear the issue isn't with the distance. The cable likely has a fault, so swap it for a new one at the store.
The cable itself was affected too, similar to what happened when a rat chewed it during work. The RJ45 tester indicated one end worked properly, while the connection between the PC showed loops—some parts weren’t recognized, others were identified. The chewing occurred in the middle XDD area.
You might have purchased a 30-meter cross-over cable and your router isn't automatically adjusting the speed. The router is likely from an older model. Are you connecting both ends together and confirming the order of the cables matches? I assume you've sent files between them at maximum speed, using gigabit transfer.
