I can't find any documentation on what it has for parts, and therefor if it could be supported.
That is the big problem with routers from trading companies who buys a router model from an unkmown Chinese mfgr and puts his logo on it.
They sell them without any support (no firmware updates), they are usually linux based but you can't get the GPL source code for it (a requirement if it is linux based), and they are probably not FCC approved.
No, there is no dd-wrt support for their routers..

And the newegg image for the tenda looks the same as mine, but in white, so I think it's a correct match.
Still no word on if any build of dd-wrt would work.
Mini-review: I got this when the wireless stopped working on my Linksys E2000, which wasn't simultaneous dual-band anyway. When I saw how minimal/sketchy the Monoprice UI was, I decided to leave the Linksys as my NAT/Router, disable its wireless, and just use this as a wireless AP. In that role, it's worked great. I can sustain >100Mbps over wireless, it never needs a reboot, connections are solid, and it successfully links with an Asus 56U that's I'm using as a wireless bridge for gaming.
So it's now just a philosophical annoyance that it's running dodgy stock firmware, but for my use case, I don't really care.
