While I own a different model Lanshare, your post is void of any detail so I'll just share mine worked fine. But my network is setup per the forum sticky and I knew to allow the ports needed through both the PC firewall and the one in the router.
I am completely boggled, and no one I know seems to have had this problem.
I have the 3.5" Aluminum Lanshare External Enclosure with Network Ethernet RJ45 & USB2.0 Interface, and it is working perfectly, with the exception of the networking function. I have the drivers, downloaded from http://www.welland.com.tw/html/support.html , and they install and work just fine.
If you see attached pictures, you can see that there is no NDAS Device # anywhere on my unit.
The serial # is ME740K06050555
Please let me know how to get this information so that I may network my drive. I have searched the internet extensively and cannot find further information on this problem.
Pics of my device are here (and yes I did remove the plastic stand bracket, and there is nothing printed behind/under it):
