For those looking to purchase a replacement wifi module for UDOO dual/quad, I found a non-bulk listing (2 per order) on Aliexpress for the GWF-3M08 wireless module. Everything else I've found on this particular module had a 500 minimum order requirement. Based on the item description, this should be a direct replacement, just make sure you order the 5V variant. These even have IPEX Sockets for plugging in an external antenna. Here's the link: http://www.aliexpress.com/item/High...SB-Module-RT5370-WIFI-Modules/1437878197.html I placed an order already (processing/shipping takes a month), so I'll update this thread with my findings when I receive the items.
