When accessing my home media server PC, a couple of my computers are failing to get a consistent video feed from the server. They're still connected, and the mouse and keyboard are still sending input, but the picture will just freeze at random times. I have to disconnect and reconnect to get it working again, and even then it won't last more than a minute before freezing up again. I usually just resort to using the Remote Desktop Android app, which works flawlessly (ironically enough).

The computers having this problem both have the same AC1200 D-Link PCIe adapter, so that may have something to do with it. The server is connected via ethernet. All PCs are running Windows 10.
