My TP-Link TP-W8960N was hit by lightning. I was on the net at the time, and it seemed that the lightning was not close (normally I would unplug the ADSL line in a storm - Murphy's law). A good bang from the router and the lights tripped. Router and it's power supply were blown. Fortunately the PC's ethernet port was fine, and this got me thinking that maybe the Router could be repaired.
I opened it up, removed 2 screws under the feet caps, and carefully pried the top cover off. No visible damage to the components on the board. Tested and found 2 surface mount fuses blown labelled L11 and L12. I soldered a blob of solder over each blown fuse (see pics) and the router works perfectly!
Interesting thing is that it is sensitive to input voltage. One spare power supply gives 12.09V which is too little for the router as it just flashes it's led's. It works fine with a power supply voltage of 12.17V.
