I'm facing some challenges with my connection and need a few suggestions. About six months ago, I moved from Xfitnity to CenturyLink. I have their fiber line and the included C400XG modem/router. After switching, my PC sometimes disconnects from the internet. Windows doesn't show any problems, but websites and online games freeze and then reload. This usually lasts 2–10 minutes before it resumes. Occasionally it happens every few hours or even more often, sometimes every 20 minutes or less. If I restart the router, it usually works again once it's back up. My PC is the only one affected in my home. It's wired via Ethernet. The first thing I suspected was a faulty cable, so I replaced it, but the issue continued. I've tested other Ethernet ports on the router. During these unstable periods, I can still access the router's web interface from my PC (192.168.0.1), which suggests the problem isn't with the cable. I've also reinstalled all Ethernet drivers, disabled CPU overclocking, and tried static and DHCP IPs. Recently, while playing Diablo 4, I encountered an invisible wall during a Discord call—NPCs vanished but my friend could see me. I searched for similar issues and found that websites would load intermittently, especially when switching zones. Interestingly, the wall disappeared only after a Discord call, which was puzzling since nothing else loaded. Eventually, after several attempts, I gave up and reinstalled Windows 11 Pro two days ago. Still, the disconnects persist. I ordered a TP-Link PCI Gigabit Ethernet card thinking it might be the problem, but the issue remains. The only possible fix now is replacing my own router instead of using CenturyLink's setup. I'm unsure if that would help since no other devices in my house are affected (my PC and PS5 are the only ones on Ethernet). Anyone have ideas or tests I could run? Do you think this might be a router-related issue? I was considering using tools like Wireshark, but I'm not sure what to look for. Thanks a lot!

This seems related to a router or DNS problem. If you can access your router, check if logging is enabled and observe the gameplay. If the external connection stays active, consider using 8.8.8.8 (Google's DNS). You should be able to set it in your router, and if that resolves the issue...your ISP's DNS server might be problematic.
