When connect the router (TP-LINK TL-MR3220v1.2) LEDs do not light up.
Having disassembled it I noticed the destruction element FB2
(pictures are not mine)
Technically I can resolder it. But where to look, what is this item?

Probably this occured because of connecting the router to the computer power supply. And it was because of using 2.5-adaptor for access 3.5 SATA drive:
(ps. sorry for my bad english)
FB means ferrite bead, you can try to remove it and solder a wire instead of it.
But I don't think that it will help... probably you have burned out also a DC-DC converter (U7, Q8) or D7 diode.
After soldering a wire it works as a switch, SYS LED not light up ;-(
only LAN or WAN LEDs depending on the connection cables.
USB does not work
