Hello everyone, I'm trying to figure this out. My internet is super fast—1 gigabit per second. But every now and then it drops to about 90 megabits per second. I have to unplug the LAN cable, turn off the router, and restart my computer in the meantime. Once the router shows it's back online, I plug the Ethernet cable back in. This keeps happening, and it's really frustrating. It doesn't make sense, especially when I'm gaming or doing other tasks that need a stable connection. I'm not sure why this is happening or how to fix it longer-term. Thanks for any help you can give me before this gets worse.

Is the Ethernet cable passing near any high-voltage equipment? It might be exposed to electromagnetic interference or have minor defects that affect performance. The cable could also experience changes in speed when negotiating links, sometimes dropping to lower speeds unexpectedly. With only four wires needed for 100 Mbps and eight for higher speeds, verify the cable is free from electrical hazards. If it remains problematic, consider replacing it and contacting your ISP if necessary.

No, that's not correct. The router maintains 90 Mbps across all devices, not just your PC. You can improve speed simply by disconnecting and reconnecting your fiber connection. It seems odd how it works—perhaps a network card would help isolate any interference from the built-in LAN.

If everything fails across all devices, the issue likely lies with the router, not the PC. Request a replacement router.
