It doesn't seem to be an issue with the laptop itself; the problem might lie with the ISP.
Yes, the laptops stopped working after connecting to Ethernet. At first, my first laptop had no issues until about a month ago. The ISP is my internet router—Xfinity with 70 Mbps download speed. My two PCs on Wi-Fi are fine, but they still face the same problem at other houses using different Wi-Fi connections.
