Need to track down a manufacturer

Hello,

I don?t know if anyone could help me. I need to track down a wireless adapter manufacturer in Shanghai. I don?t know where to start. Tried to track by myself but it appears that the manufacturer doesn?t have a website.

7u(P3meOb2y I made serveral inquiries with different manufacturers and that wanted to sell to me the same product with the same plastic mould, with the same chipset and with the same product location and the price almost equal from everyone. So it has to be a main source that i need to find it out. I don?t want tradings in the transaction. :(

don't you know its name, or phone numbers?

Do you have his information?
