Question LAN connection problem...

[Jason JX]

Hi guys, I have a problem need to ask help from all of you...

Yesterday I have formatted the CPU. Before that the network driver of LAN (Realtek PCIe GBE) was fined, but after I formatted it, the network adapter was missing. Actually it can open back by switch the Show Hidden from View in device manager. But the problem is, when the network adapter has show, the LAN driver still missing (all the driver show from hidden is WAN miniport or something same as it).

I have tried to download the LAN driver and installed it but the message box show "The Realtek Network Controller was not found. If Deep Sleep Mode Is enabled Please Plug the Cable." . I just know turn off the deep sleep mode by using the step (Device Manager > Network Adapter > Driver > Properties > Power Management) but the driver is missing.

The things that i have tried:

1. Install driver by using motherboard driver disc.
2. Install driver by download from internet.
3. Check bios but its enabled.
4. Can used wireless adapter to connect WiFi.
5. Network port on MTB: Activity LED got light but Link LED don't have.

Anyone can help me fix this problem?

Are you on the latest BIOS update for your motherboard? Are you using the same installer for your OS? Speaking of OS, which OS are you trying to work with?
