with your modem still connected to the DLink go back to the Command prompt and type in Ipconfig /renew and copy the results back into here <Reply 1>
After that go back into Command prompt again and Type in ipconfig /all and copy the results back into here <REPLY 2>
I have a desktop which uses a cable that connects to a wireless router/modem. Everyone in the house (like 3-4 other laptops uses wireless connection) yet the desktop has a cable line attaching to the modem. I was using the computer fine till half way last night and it got disconnected from the internet and I couldn't get back on again. Internet and modem is fine as everyone including my laptop is able to go on the internet.
I've tried ipconfig renew/ release and the netsh int ip reset resetlog.txt , netsh winsock reset catalog and it still shows up this error unable to contact your DHCP server.
