I bought a Refurbished Asus RT-N66R from Newegg Flash (http://flash.newegg.com/product/N82E16833320154), hoping to setup Rsync (installed on MicroSD syncing two external USB hard drives). Turns out, there is no MicroSD card slot inside like the rest. I replaced my RT-N65R with this router because of the SD card, and its not there. Since I opened it, the warranty is now void. It looks like there is a spot for the SD card, but there is no carriage for it. Am I able to solder a microsd carriage to the board? is this typical of a refurbished unit? The Mainboard says RT-N66U REV 3.21.
