Realtek PCIe GBE Family Controller isn't showing up in my system and I can't reinstall it. I've already tried everything you suggested, but now only WAN Miniports remain in Device Manager. Let me know if you need more details! I've been without internet since August.
Purchase a low-cost PCI-E LAN card and the issue is resolved. Verify in BIOS that your onboard LAN is active. Also, clear old LAN drivers via Raspberry. Confirm if the hardware is faulty by booting from an Ubuntu live USB and testing internet connectivity. Review available services. Consider using the Windows built-in troublesooter to auto-detect problems. Numerous solutions exist.
I could purchase a LAN card, but since I don’t need it, I’m not interested. I’d rather avoid dealing with any operating system, so that’s out of the question. Instead, I’ll go for the LAN card. The Windows Troubleshooter gives the same advice no matter what I try to do. It’s already turned on in my BIOS.
Use a Linux live USB, it won’t affect your PC’s files or operating system. It clearly indicates whether the issue is hardware or software. Perform a BIOS reset if needed.
If you don’t want to try simple fixes for starting a Linux Live DVD or USB, consider getting a budget PCIe NIC—preferably from Intel for better performance and reliability.
I'll attempt the Linux option. Don't worry about storage limits—it won't be an issue.
You don’t need an 8 gig USB drive if you have a smaller one that fits your needs.
It doesn't save the file to your hard drive. It starts from a USB drive. Your main storage remains untouched. Make sure you have enough empty space; too little can cause problems.
