I am running Windows Vista on my computer and also have a Norton Protection Center. So, when I usually test the non-connection problem with router then I have checked that the Local Area Connection says that the connection is "Local Only" and the computer wont let go to the Automatic Private IP Address. When I try to renew or release then it will not create any errors but it will also not let go of the APIPA. I have disabled Norton Protection Center and also removed it from msconfig. I have also disabled Windows Firewall all together and the DHCP is able to see the proper MAC for my NIC, and is also assigning an IP Address. After that I have disabled the IPv6 and only had IPv4 and even rebuild TCP/IP but still getting the same problem? A little help please.
