Hi All, New member here. I believe these issues have been discussed before, but it appears my problem is different (slightly...). I've read most, if not all, the previous threads as well as some others, but I'm still at a loss. Here's what happened: Installed new wired Gigabit adapter D-Link DGE-530T) a few days ago. Ever since, that connection shows as Unidentified Network' in NW and Sharing Ctr. Even though I've changed permissions in Local GPO to allow users to change NW location etc, I can still not do so. When I run the Troubleshooter I end up with the 'invalid IP config' diagnosis - even though ipconfig sometimes lists it with a valid DHCP config obtained from the router (D-Link DIR-655). Wireless connects just fine, and there is no problem when I switch to my onboard NVIDIA adapter (10/100 only - I'd prefer to just disable that one in the BIOS). Have done pretty much all of the methods suggested in previous posts (ipconfig /release/renew, deleted routeing table, flushed DNS cache, etc. Also removed 'phantom' adapters in Device Manager, reset and reconfigured router removed/reinstalled NIC, even replaced it with aanother one (same model). Nothing seems to get this thing to work. Am I missing something here, or what am I doing wrong? Any advice? Thanks!
