Network unidentified via ethernet, not found on wireless - affects only one computer

Hi,
I have some problems with a computer that I hope someone in the community may have encountered before.

Background: It may not have been causative, but the problems occured after a power outage and being forced to restart a router.

Description: I have several computers and devices connected on a D-link 655 router, both wired and wireless. One computer did not manage to come back up on the network all of the sudden.

Using wired connection it shows unidentified network. I've tried changing ports and cable.
Using autoassign IP it gets an IP from the router (via the routers status page) but ipconfig /all on that computer reveals that it is using another IP (preffered, last resort IP I guess). Setting the IP to the assigned IP etc does not resolve the connectivity issue although the settings on the adapter now looks alright.
Using a working wireless network adapter the computer does not event detect the wireless network of that router. It does however show multiple neighbours networks with faint signals...

So somehow it seems that windows is completely unwilling to collaborate with that specific network.. and that pretty much out of the blue (the computer has previously been working fine on both wired and wireless network to that router).

Anyone that got any idea about this?

Update: Running Windows 10 on the affected computer

Thank you for your suggestion, resetting IP stack was not succesful, nor was reinstalling the network adapter (only did this for the wireless one out of convenience).
Quite strange that the wireless stick, freshly installed, won't recognize the network on that computer. Especially since other units see and are able to connect to the wireless.
 


I thought that was rather odd, too. Maybe someone will chime in here with another suggestion.
