My computer’s ability to connect to the Internet failed suddenly this morning while rebooting between my Linux and windows 10 dual boot. My Internet is working fine, with other devices totally able to connect. However, no Ethernet connection can be established, and no Wi-Fi networks can be found, not even for my neighbors. The network adapter didn’t appear in the device manager, but the Bluetooth adapter does, despite both being attached to the CPU. Is this a hardware issue, or should I do something with the Windows 10 OS? I cannot replace the network adapter, since it is part of the CPU.
