Limited or no connectivity
Posted on 2011-05-04
I have a laptop in a Windows Domain that is connecting via wireless but will not connect to our wired LAN. This is a new issue as it has always worked before. I have uninstalled the NIC, updated the drivers, ran the repair, verified that Automatically Detect DHCP and DNS are selected, run an IPCONFIG /flushdns, and IPCONFIG /registerdns, disjoining it from the domain, rejoining it to the domain, re-imaging the computer completely, and running enough MS Fixit tools to choke a donkey. The ethernet connection will work sporadically for 2-20 minutes, but will always lose its IP and go back to the APIPA address in the 169.x.x.x. range.
