Problems will be assigned IP number can apply both with and without cable. I have not understood what caused it but the symptoms are addressed with the instructions below. Typical symptoms is that no or incorrect IP numbers [type 169.245.x.x] assigned to the NIC. It can be seen by the command window [CMD] write ipconfig /all or right-click the icon for each network adapter and select Status > Information.
To check that there is another error, you can try to work with a static IP address of the network you are in.
To get DHCP to work, you need to reset the network card.
- Open a command window as admin.
- Type the following two commands
netsh winsock reset
netsh int ipv4 reset
Restart the computer
Now assigned to the computer an IP number from the DHCP server. Why it does not work to just reboot the computer I do not know but it is certainly an update on this.
