I went back to re-read the thread and there's definitely some confusion here (above and beyond any driver issues). We need to get some terminology and hardware facts clear i think
Tell me if this is correct / you agree
1. You have an MSI 785GM-E51. I checked and, yes, it has an
onboard Realtek ethernet controller. (that's what you saw reported in everest)
2. But you say you
added a board from your brother's computer???!
> I think that board is a
WIRELESS network card, it's NOT an ethernet controller. Ethernet cards have an RJ45 jack for the network cable. That board doesn't connect to your LAN with a cable, does it??
> You probably only find
one RJ45 jack and that will be for the Realtek onboard ethernet controller!
3. You are having problems with the
onboard Realtek ethernet controller on your motherboard. This is a separate issue (and different hardware) then the wireless card you added from your brother's computer
Let's just talk about the Realtek controller for the moment. The Realtek is detected by Windows and appears in dxdiag, but dxdiag doesn't report any driver files installed for it. (if you look in your dxdiag's System Devices section, you'll see...
Code:
Name: Realtek PCIe GBE Family Controller
Device ID: PCI\VEN_10EC&DEV_8168&SUBSYS_75961462&REV_03\4&206601F1&0&0028
Driver: n/a
1. Open Device Manager. Look for Realtek under Network devices (or it may be under Other devices). Right click Properties, look on the General tab. Wjhat is Driver Status code?
2. Look in Add/Remove Programs. If Realtek network is installed, uninstall it
3. Go the MSI website for
MSI 785GM-E51 First, reinstall the system chipset drivers. Then reinstall the Realtek PCI-E Ethernet Drivers
