Subject: [BAWUG] Help - I killed my Netgear ME102


Greetings all,

Here's my situation:

I intended to set up two Netgear ME102 AP's in "semi-bridge" mode; that is,
leave one running in Access Point mode and set the other to Access Point
Client mode. I needed to connect a small wired LAN /and/ a laptop with a
wireless card to a shared broadband connection, which is why I chose that
configuration instead of just setting both of them up in bridging mode.

One of the AP's was bought new from a retail store; the other I got from an
Ebay seller.  Both AP's worked fine as stand-alone access points, although
the firmware was slightly different (New AP: 1.4h.4/Used AP: 1.4h.3).
However, my initial attempt at configuring one as an Access Point Client
failed; the AP's did not seem to be communicating.

In the process of troubleshooting this I visited the "Wap11 Hack" webpage at
http://www.seattlewireless.net/index.cgi/Wap11Hack and learned that the guts
of my ME102's were equivalent to Linksys WAP11s and a couple of other
models. I downloaded the Atmel SNMPManager utility in order to have the
additional test and configuration ability that it offers over Netgear's
packaged utility.

At one point, while trying to configure the Ebay AP, I chose the "Restore
Defaults" option. The settings that were restored did not appear to be
default values at all: the SSID reverted to "DORA", the IP address reverted
to a static Class A address, etc. I also noticed that the MAC address shown
by the utility did not match the one on the bottom of the AP -- the utility
showed "00:00:AA:BB:CC:0D" as the AP's MAC address. I found this to be very
strange, so I set out to upgrade the firmware in hopes that perhaps "normal"
defaults would be restored.

Netgear, however, doesn't show rev 1.4h.4 on their website (even though it
came loaded in the retail AP), and Netgear's upgrade utility won't allow you
to overwrite FLASH with the same version. So, I downloaded a version 1.4j.1
from the Wap11 Hack site that /theoretically/ would work on any AP with this
type of hardware. It came with a utility for upgrading via Ethernet. The
upgrade seemed to work correctly, but when I power-cycled the AP, it was
DEAD. The power light came on, but the second LED (with the antenna symbol)
did not. The Ethernet interface did not come up either (a Fluke LinkRunner
shows it as an "unpowered hub"). When I attempted to connect through the USB
interface, my laptop described it as an "Unknown Device" and did not load
the proper driver. Thus, any attempt to use a USB utility to talk to the AP
results in a "USB DFU driver not loaded" or similar message.

All I could imagine was that the firmware file I'd loaded had been invalid,
or that I'd loaded it incorrectly. Having nothing else to lose, I
disassembled the AP in hopes of finding a reset or boot-mode jumper...
anything that would let me talk to the AP at some level and re-load some
valid code. No such luck.

Has anyone ever killed their AP in this way?  What did you do?  Obviously,
since this one was used, I have no warranty or any expectation of support
from Netgear (although I'll probably ping them anyway).  I did notice that
the FLASH chip used in this unit is an Atmel AT29LV040A... which I could
write to using a PROM programmer if I had the correct image.

Any help would be greatly appreciated.  BTW, if anyone would like to know
more about the inside of an ME102 without having to rip up a functioning
one, e-mail me and I'll be happy to send pictures or answer questions.

Thanks,
Josh Freeman
