So, here's the deal. I recently got that error. It says that I have Limited or no connectivity. I can't figure out what's wrong. I get an IP like 169.xxx.xxx.xxx. WTF! I tried almost everything I found on Google, but no results. I tried : Repair connection Disable/Re-enable connection Delete/Re-install adapter (NIC) WinSockXPFix Manually assign IP address Re-setting BIOS Changing modem and cable Using many IPConfig commands (Release/Renew/etc) Editing registry (EnableDHCP/etc) Editing MAC address Even resetting/reconfiguring modem And EVEN reformatting PC But nothing. I am totally confused. Oh! And I tried my network card on my old PC, somehow, it works. For now, I'm using USB modem, it's quite slow, that's why I want Ethernet back. I know that the problem isn't the modem. My laptop (Win7) works both Wired and Wireless with both modems. I would appreciate your help.
