[SOLVED] "The realtek network controller was not found, if deep sleep mode is enabled, please plug the cable" ?

[koolaidman221]

I have a Ryzen 5 5600x, ROG 6700xt, GIGABYTE Aorus b550M Pro-p, and a EVGA Bronze power supply. The situation started one day when attempting to boot up my computer for a quick game session the ethernet seemed to not work. I tried many things like restarting my PC, redownloading the LAN drivers, and checking all of my ports and connecters. I also updated BIOS and Windows fully and also looked through my bois for any deep sleep mode.

Message that popped up after downloading my LAN driver

. Hopefully the issue is something related to that and not hardware.

There's also a list of the network adapters in device manager . (the top one is the network adapter i'm using temporarily.)
Any help is much appreciated

When they don't appear at all in the device manager it is not a good sign. If this was a new install you would suspect a missing motherboard driver but since it was running this is unlikely unless you updated it.

Try to get into the bios directly at boot rather than using any app running under windows. Some motherboards let you see the status of the ethernet.

Since you updated the bios this also tends to reset the bios to default so it should have reset any strange ethernet/power save options.

I suspect you have a failed ethernet port. Lucky you can get PCIE or USB ones pretty cheap. If you have room a internal card is your best option, nothing real special is needed since even the short x1 slots can easily do gigabit. If you use USB you want to use USB3 devices and ports to get full gigabit speed.

.....a side node that wifi card you are using is a very poor choice. Any of those very tiny USB wifi have small antenna and low power

My PC cannot fit any wifi card, is it worth it to use the motherboards warranty and wait for a replacement?

The problem with the wifi is not that it is USB it is that it is so tiny. The larger units designed for desktops work much better.

Up to you if you can get it replaced under warranty. The cost of either a internal PCIE card or a USB3 ethernet is about $15. Maybe less hassle spend the $15
