Hi so a few weeks ago it was raining and I didn’t know so lightning went off near my house and my computer froze so I turned it off by holding the power button and left it off I got back on it a few hours later and my Ethernet port on my pc was no longer working and my WiFi worked but when I tried to go to browser it just said network error while it was connected. I decided to buy a usb to Ethernet adapter and it works fine but it still dose the same thing as it did on WiFi then I noticed the light was blinking orange on my router where the Ethernet cord was plugged in I’m pretty sure there’s nothing wrong with my router since my brothers computer connects and runs fine but mine just doesn’t and I don’t know what to do my last step is getting a whole new motherboard cause I feel like it had affected it to the point where it won’t let me do anything on the internet please help.
