Realtek ethernet strangeness


There is a newer firmware for the realtek 8168 and so I updated to use that new firmware. After rebooting I got no link-light. I feared that I may have bricked my ethernet controller. So I reflashed the bios and reverted to the previous ethernet firmware. But still no link-light. Okay so I powered down the system and rebooted. Still no link-light. Changed the ethernet cable. Still not working. Finally I unplugged the PSU and bled off any capacitor storage. Powered it back up and now I got a link-light.

Just posting this in case you have one of these realtek ethernet controllers. Mine is built-in. I do not know if this is particular to realtek or not but I suspect that it is.

Usually the firmware is initialized by powering up the device.

Actually kernel driver has the ability to load firmware. Firmware must be provided by user, of course. Kernel has no 8168 driver, so in most cases 8169 driver is used instead. You can inspect your dmesg to see if the driver is requesting firmware.
