Thank you so much! Have been struggling with this for weeks. Your English is 1000 times better than my French, but let me put down how I deciphered your instructions and fixed the problem: - Open Device Manager - Click your Network adapters - Right click your device, choose Properties - click Advanced tab - Click on Speed and Duplex Settings - Choose Auto Negotiation in the Value Tab - Click OK Thank you again...
