My Ethernet adapter is broken again right after I turned it off and on.
My wired internet line isn't working after a week when I turned on my computer. I checked the cable on another PC and it worked there too. My router is fine, so now I'm using a wireless USB adapter for my computer. But I need to figure out why the ethernet isn't working. I am on Windows 10 with a Gigabyte Aorus Z590 Elite MOBO. In Device Manager, the Realtek network adapter didn't show up. It was listed under hidden devices but marked as disconnected (Code 45). After uninstalling the driver and reinstalling it from my motherboard manufacturer's site (as an admin user, trying all versions while rebooting), the Realtek adapter never came back in Device Manager after that restart. That's worrying. I tried a few other things: running Windows Troubleshooting to reset the network connection, testing the cable with another laptop and having it work, rebooting into safe mode (but ethernet still wouldn't work), and using Command Prompt commands like netsh winsock reset, netsh int ipv4 reset, and netsh int ipv6 reset. Even checking the BIOS status showed that LAN adapter is enabled. I'm worried maybe the adapter on the motherboard just fried itself, but before giving up, I want to try other fixes. What else should I check?
Run the command ipconfig /all from Command Prompt. Copy and paste those results to see what's there. Check if your network adapter shows up when you run Get-NetAdapter or Get-NetAdapterHardwareInfo in PowerShell. Use only the basic "Get-" commands and share the output. Watch out because your network name might show up, so just hide it by writing REDACTED instead of the real name.
I appreciate your reply. Here is what I found: Running ipconfig without connecting to Wi-Fi showed no wireless adapter information. When I connected the laptop to Wi-Fi, the output was very different. It listed two Wi-Fi adapters with physical addresses like 26-05-0F-F6-E3-14 and 24-05-0F-F6-E3-14, both saying that DHCP is enabled and autoconfiguration turned on. One adapter has a link-local IPv6 address (fe80::581b...) and an IPv4 address of 192.168.1.28 with a subnet mask of 255.255.255.0, showing that the lease was obtained on Monday at 3:54 PM but expires on Tuesday at 3:54 PM. The default gateway is 192.168.1.1, and the DHCP server also shows up as 192.168.1.1. Some other commands didn't even return a response at all, so if you want more specific info I should try different Get commands. There seem to be lots of options but many don't work well with this setup.
