I think for this to be viable market place item it needs to be sold on Amazon.com for the US and much of Europe.
As a vendor, to be taken seriously, you should have a direct link to the product and complete specs on your own website. I can not find this on the ".com" site. The ".cn" site shows at least six links to the same FS-WR106 at different prices, too confusing.
Exactly what version of what is on the delivered product, and is there a repository that supports this. You have nothing on the OpenWrt site. What is meant by a "Support System"?
You reference OpenWrt, but this is LEDE. I will suggest the following actions:
1 - Send some sample units for free to the developers
2 - Build a version based on 17.01 if possible, and submit required patches for upcoming maintenance releases so this can be made available directly from LEDE.
To stand out as a vendor, I will suggest you create an enhanced version of firmware, again based upon the standard release, that offers support above the basic LEDE image for all included hardware features in your device. As VPN is popular, a additional version with OpenVPN installed might also be good. These firmware's would be made available from your site's product support pages and should most importantly use the standard repository for the base release version of firmware.
You also should include a list of the PCIe modules you have tested and approved, along with documentation for how to install\configure these for LEDE.
Indirectly related, on your .com site you have at least 3 links to (the cute) FS-AP221. If they are the same there should be just 1 link, if they are different they should have different part numbers.
There are very few devices available with OpenWrt installed from the factory, and there are NO LEDE devices at present. It does not matter how truly good your device is at this point, you need to build some credibility. This starts with good content on what you are offering, followed by a product with a factory delivered release version of LEDE (even the basic image to start as this is easy to upgrade) and a global delivery channel.
