I bought a ethernet cable months after my brother purchased the extender. He stopped using it and didn't need it anymore so i asked if i could have it he said sure. The wireless connection worked fine, not fast but it worked. So I decided to try the wired connection. It worked great for the first day or so with much higher speeds. But then the connection would not work. I tried rebooting, changing setting on the extender and pc side. Nothing is working. It registers that it's working on my PC but there is no actual connection but the wireless still works. I updated the firmware and it worked for a short time before it stopped working again. What is wrong and how do I fix this?
