This error started showing up after updating the driver for Intel 6300 wifi card on 64 bit Win 7 Pro.
Your computer was not assigned an address from the network (by the DHCP Server) for the Network Card with network address 0x2475130D0331. The following error occurred: 0×79. Your computer will continue to try and obtain an address on its own from the network address (DHCP) server.
The network address is the MAC address of the card receiving the error. 0x2475130D0331 looks like this as a MAC 24:75:13:0D:03:31.
Open up a CMD line prompt and enter “ipconfig /all” to display the list of network connectors. What you will probably notice is there will be an MAC address that the last digit is different. That is the actual wifi card that has a good IP address. The other is the MS Virtual WiFi Miniport. This can be verified in the Network Connections panel showing the Red X on the adapter showing it has a signal but not connected.
This is the virtual network filter that can provide sharing of the WiFi adapter. In the CMD line enter “netsh wlan show hostednetwork” and the name of the hosted network will be displayed along with the status. To get rid of the error set this hostednetwork to disallow from the CMD line. “netsh wlan set hostednetwork mode=disallow” That should do it. – CDaze
