I recently had wired internet set up in my home using Cat 6 cables, but I'm only getting around 100 Mbps, even though my ISP plan is supposed to deliver up to 300 Mbps. Interestingly, my Wi-Fi connection gives me speeds of 250-270 Mbps. My motherboard, a B550M-WIFI II, is supposed to have built-in 1 Gbps Ethernet and Wi-Fi, but I'm not achieving those speeds. I've installed all the necessary drivers, and my router is capable of handling 1 Gbps ports according to its specs. I haven't contacted my ISP yet, and I can't add a new PCI network card since my GPU is blocking the slot. Could purchasing a USB network adapter help? I feel like I've already tried most common troubleshooting methods, and it's frustrating to have paid for installation and not see the expected speeds.

Check the connection status in your settings. Click the Start button, type 'View network connections,' right-click on your Ethernet adapter, and click 'Status.' What does it say for the speed?
It sounds like a tricky situation, but the first thing you should try is moving your PC closer to the router and connecting directly, just to see if that improves your speeds at all.
If you're using an ethernet switch, make sure it supports speeds beyond 100 Mbps. Also, check if the cables got damaged during installation; a basic continuity tester can help. Ethernet at higher speeds needs all four pairs, so any damage might drop it down.
Noticed something odd? If your router has a green flashing link light but your PC shows a static orange light, that might indicate a speed issue. Check those connections!
It's worth checking your RJ45 connectors for defects by trying a different cable. Also, ensure the cable definitely meets its rated specs. If all else checks out, you might need to consider if the router or your network settings are capping your speed.
