I have a Zonet ZSR1104WE Wireless Broadband Router. It's about 3 years
old, and until last night worked just fine. After a storm last night,
the router quit working. It shows no signs of life.

I've tested the AC adapter with a meter, and it's showing 16V (no load.)
So, I opened the case up and started tracing the circuit. One diode (D1,
IN5.... (can't see the numbers)) near the power input has shorted (tests
open both ways), but my question is where to go next? I've looked
unsuccessfully for a fuse of some sort, the next components in the
circuit are a B1412 transistor (Q5) and a choke (L1.)

From the B1412, the circuit continues to RT34063a (u9) and then to a
series of resistors (R9-R5).

Any help would be appreciated.

Do yourself a favor: throw it in the trash and get another router, they are
cheap and disposable like inkjet printers. Unless you have so much time on
your hands that you'll spend $500 in labor to fix a $40 router...

I opened up a fried D-Link router once. Once. It was one large proprietary
IC and a handful of sMC passive components. I replaced about 5 or 6
wireless cheap-o-deluxe routers, one about every 6 months, in my office
before I was beaten into submission and bought a $400 Cisco unit which has
since performed flawlessly for 2-1/2 years. Consumer-level networking
hardware is C-R-A-P from the design to the final assembly in some Cambodian
sweatshop. that's why Cisco, of whom LinkSys is a wholly-owned subsidiary,
won't brand LinkSys *** with the Cisco logo.
