Linksys BEFW11S4 router repair

Hello,

I have a Linksys BEFW11S4 router (802.11b) that suddenly stopped
working. Does anybody know if these can be repaired? I am pretty sure
the power supply is working correctly, but I need to check in more
detail. How are these units opened up? There are no screws...just some
tabs or holes where a screwdriver can pop these tabs. Could it be a
SMT or standard fuse that fried on the unit?

Thanks.

Throw the thing in the trash and go get another one or if the wire is
still working, then convert it to be a switch and use it as a switch.
You may get another year out of it.

I don't believe that there are any fuses within the unit. It is held
together with those little tabs. How do you know the power supply is
working? How did you check it? It should be supplying 7.5 VDC

IIRC, it's similar to all the other Linksys boxes, pop the tabs up and
slide the front off.

However, I'm with Duane, toss it in the trash and get a WRT54G(L),
except for the experience of disassembling it, there's no value left
in a dead router from the 90s.

- Symptoms?
- Any lights on the front panel?
- What happens to the lights immediately after you turn it on?
- What hardware version of the BEFW11s4? It's on the serial
number tag after the model number.
- If the lights look normal, can you get a DHCP address on a wired
client? (Never mind wireless for now)
- If the lights look normal, can you ping the router at 192.168.1.1
via a wired connection?
- If the above two tests work, you might consider reloading the flash.

>Does anybody know if these can be repaired?

I'm sure there's someone out there that knows if it can be repaired.
Unfortunately, with the symptoms and details you've supplied, there's
not much I can offer. Whatcha got and what's it doing?

$8 will buy you a DVM (digital volts guesser). It's a handy item to
have around. The later power supply is rated at 12 volts, while the
early versions were 5 volts. The exact voltage is not critical for
the BEFW11s4 as it will run on anything between about 4VDC and 18VDC.
Measure the voltage.

The black and blue parts of the case come apart using brute force. On
some models, there are screws under the rubber feet. See:

for details and destructions.

It turns out it was the power supply. I found another similar spec'ed
PS and
it works like a charm now.

I tried the old power supply and noticed that I am getting a whistling
sound from it...a very
light sound. I cracked open the dead power supply and it looked like
one of the caps was melted or at least another component near it was
melted.
