I dont have a picture but follow these directions and you will be able to find them:
Remove all 8 antennas---Flip the router so the rubber stoppers are facing up AND all ethernet ports/reset button, etc., are positioned to your LEFT--- Remove rubber stoppers in the bottom (you may have to use some force to pull them as they are glued there)---This will expose all 4 screw holes---remove all screws---then remove the bottom plastic cover using a sharp boxcutter blade while keeping the router in the same position as above ---now your circuit board is exposed---remove the 2 screws that hold your board in place (you may have to look carefully until you find them---once your board is loose gently pull it out of the top plastic cover.
Now flip the board so the ethernet ports, etc are still facing your LEFT side---Once you do this your 4 PINS sticking up will be on the RIGHT side of the board----the one closest to you is the Vcc one---the one farthest from you is the GROUND one----the two in between are the Tx and Rx ones (I dont remember exactly which one is which)---you can use a multimeter to test each pin if you would like
IMPORTANT to know: DO NOT connect Vcc pin to any of serial cables---the only router pins you connect to your serial are: GRD+Tx+Rx (the order of which is GRD+Rx+Tx on your serial cable)
Use Putty and save your router settings and you will be good to go (see Wiki for more info on how to configure Putty).
Once you get to cfe> in Putty you erase NVRAM and then REBOOT. Wait for a while and once you see all lights flashing, your RT-AC5300 is breathing life again!!!
