Connection instability occurs unpredictably.
Connection instability occurs unpredictably.
You've managed to keep your PC running smoothly for nearly a year on Ethernet, but recent changes have introduced instability. The issue started after upgrading to gigabit internet and replacing your modem with an ATT unit. Now, your PC intermittently drops connections, sometimes showing it's connected while other times reporting no signal. This behavior was unusual before the modem change and has persisted despite attempts to fix it—swapping ports, resetting the device, or updating drivers. Since your PC is the sole Ethernet-connected machine in your home, it’s hard to pinpoint whether the problem lies with your internet service or your computer itself. Other devices in your house are primarily used for streaming and don’t experience long outages, making it difficult to isolate the source. As a competitive CSGO player, you’re frustrated because your gameplay freezes during critical moments. You’ve ruled out major hardware issues, but without a dedicated Ethernet card or alternative connection, troubleshooting becomes challenging. Consider consulting a professional technician who can perform a more in-depth diagnostic, possibly checking for network configuration errors or hardware faults.
This problem might have happened if you upgraded to gigabit speeds. My internet service provider needed to replace the cables because they were outdated and unsuitable for higher bandwidth. It’s worth checking this, particularly if your home hasn’t received any electrical or fiber improvements recently.
