Interesting problem here. We have a remote site with about 5-6 PCs on that network. They all use DHCP off the router to obtain their IPs. All the computers work except one. Keeps prompted me for limited or no connectivity. I tried assigning it a static address on that network and it won't let me ping anything on that network. I've done a loopback test and looekd athe most recent drivers and they work fine.
The computer can connect fine to wireless, but can not wired. I had the laptop swapped out with another on a docking station that I know works to elimiate any bad cabling and still experience the same issue.
I can not ping the router either when I assign it a static address.
