N750 and N900

Do these routers have support for jumbo frames?

Nobody responded.  Can you explain what you mean by jumbo frames?

Do the ports support  an ethernet frame with more than 1500 byte payload ( http://en.wikipedia.org/wiki/Jumbo_frame)? Most home routers with gigabit ports support frames up to 9000 bytes. 

well, according to the user manual, the routers follow the IEEE specifications (at least for the wireless distance covered) but i assume it follows these standards and specifications for pretty much everything else it comes it, and according to that link on wikipedia the IEEE does not recognizes the jumbo frames…so id say these routers does not support jumbo frames.

but thats just my guess x_x maybe some wd engineer will know better ;D
