Hi,
Sorry for the delay and for not being so explicit.
Well, the WZR-1750DHPD is already shipped with DD-WRT, so I think it
would not be so hard to port it to OpenWRT.
I just have the hardware and I'm able to compile OpenWRT and test it. I'm
a C programmer, but I don't have a very good device driver programming
skill.
I can do any tests using that device.
Following is the hardware specs ...
