Network changes occur unpredictably between Gigabit and 100 Mbps speeds.
Network changes occur unpredictably between Gigabit and 100 Mbps speeds.
Hi everyone, I'm facing an issue with my home network setup. Previously it worked perfectly, but now sending large files from my gaming PC to the NAS causes problems. The network switches abruptly from gigabit to 100 Mbps each time I connect. For instance, a 200 MB file is being sent at speeds above 100 Mbps, depending on drive performance. However, after a few minutes of a big transfer—like 500 GB—it disconnects and reconnects to 100 Mbps. This is really frustrating... Any advice or help would be greatly appreciated.
AFAIK ethernet cables typically last more than a year. Before, I didn’t face any issues. For the gigabit Ethernet cards, I’m connecting through the motherboard ports—wouldn’t be surprised if those are the main concern. Do you agree?
Do you have another device to check? I think it might be one of those network cards on your network cable or switch. Start with simple steps. If you have an extra cable, swap it between your computer and the switch. Make sure your network drivers are up to date. Watch the switch while a big file transfers—check if the lights change oddly when the connection drops. Ideally, your computer link should only briefly fail before returning.
If the Ethernet cables were low quality or damaged internally, environmental shifts might add sufficient noise to the signal. This could make the cards attempt to slow down to restore stability. Additionally, motherboard NICs are prone to failure—this isn’t a new issue.
You're welcome! I'm glad you're confident about the cables. I'll keep an eye out and let you know if any problems arise.
