Network (Wired and wireless ) sectors and usb without electricity
My model is raspberry pi b. When I connect the device to the power, it starts to boot without problems, but there is a flashing yellow mark on the corner of the image. But the usb section and the network segment do not work. I replaced the power adapter and cable, but the problem still failed. There is a part called polyfuse that I tested, which seemed to be healthy.
