Linksys Wireless Router :: E4200v2 - Error Code 0x80070035 Network Path Not Found

I thought I would leave a message on a problem. I did two chats to the support desk and this was not brought up and it is obvious.   I just installed the 4200v2 as a replacement for a NetGear.  I bought for the n performance and the USB for a shared disk/media file server.  I connected a640G Western Digital My Book to the USB.  I was able to see the drive in the asp interface of the router, but I kept getting the "error code: 0x80070035 network path not found" message.  My computer is a 6 month old HP with Windows 7 running Bitdefender Internet.  I found I could get to the drive from my wife's  Toshiba (only used for browsing, so minimal security), so I thought it was a firewall issue (also what Cisco said).  After doing some Internet mining, I found that the issue is the Netbios setting in IPv4.  My PC had the setting Default, which requires the DHCP server to provide the setting and apparently this was not set by the 4200.  Without Netbios the disk cannot be mapped. Changing this to NetBios "enabled" solved the problem. This can be reached by going into the Control panel:Network and Sharing Center.  Click on the connection (either local area or wireless), then open the properties, click on the TCPv4, Click properties, then advanced.  Go to the Win tab and select Netbios enabled.
