My Killer E2200 Gigabit keeps getting downgraded to 100mbps after the system has been running for a few minutes. I'm running Windows 10 v10.0.18362. TP Link Archer A7.
When I first boot the system, I open up the Control Panel Double Click the Connection and it shows 1.0gbps. Speedtest confirms I'm getting my full 400mbps from the ISP. Then 30 minutes or less later, I check again and it's been capped at 100mbps. Duplex is set to Auto Negotiate. I've restarted modem and router. What am I missing?
