Hi cbcaso,
Are you using the same system as mentioned in the title? If not, please share the exact system model in use.
If the Network Controller has a yellow bang in Device Manager then it points towards a driver issue. Please share the Hardware Id of the Network Controller in question. You may follow the steps below to check the Hardware Id :
- Open 'Device Manager'
- Right click on 'Network Controller' and click on 'Properties'
- Click on 'Details' tab and select property 'Hardware Id'
- Please share the Hardware Id information here.
Please reply with the findings. Will take it further from there.
