I've been asked to assist with a D-Link DWL-2700A access point at a RV
park.

Not too horrible a unit. It should work.

Practice on the emulator before you destroy something:

The owners are unhappy with the company that installed the unit
and would like to sever their relationship.

Ah yes. The divorce ceremony. Wear safety glasses and a helmet.

Thus, I was preparing to
make a configuration manual (via screen shots) of the setup for their
records. I believe the default IP address was changed to 192.168.0.2.
However, attempting to login to the WEB interface from a Vista machine
(wired connection or wireless) is not successful (Page not found
error). I downloaded a setup program from D-Link. It finds the
access point (when a wired connection is used, but not wireless) but
will not permit access with the password that was given to the park
owner.

The device is an access point, not a router. Access points do
bridging (IP layer 2) and NOT routing (IP layer 3). You will not see
the access point's IP address in any traffic that is not specifically
directed at the access point.

My guess(tm) it was left at the default IP of 192.168.0.10. Try it.

The owner suspects that the company changed the password the last time
they were on site without telling the owner. Job Security! The
password to the phone company DSL modem also doesn't work -- that one
we can get back by reseting the modem.

I do that even to my best customers. All of them seem to have friends
and relatives that are hackers. If I'm expected to guarantee reliable
service, I also have to protect the system against friends and
relatives as well as hackers.

The password to your unspecified model DSL modem is usually printed on
the bottom of the modem. If it's an AT&T system, which uses
SpeedSteam 4100 DSL modems, the password can be changed. However, you
will need to reset the modem to defaults in order to use the printed
password. Perhaps it would helpful if you would kindly describe the
system and all it hardware and software.

DO *NOT* try to configure the DWL-2600 via a wireless connection. Not
only does it often screwup, cause a disconnect, or otherwise ruin my
day, but admin access via wireless can be blocked. That might be
what's happening to you. Find a cheap ethernet 10/100 switch and
stuff it between the DSL modem and the DWL-2600. Plug in your Vista
nightmare laptop. All the lights should indicate a connection. Now
try http://192.168.0.10 or whatever.

If you can't get a web page, look on the DWL-2600 for the MAC address.
You can miss it although it might look like a serial number. If your
Vista hasn't crashed, try:
Start -> Run -> cmd <enter>
to get to the DOS prompt. Then run:
arp -s 192.168.0.99 00-aa-00-aa-00-aa
That sets the IP address of 192.168.0.99 to the MAC address of the
DWL-2600. Then try:
http://192.168.0.99
There are a few other things that may screw this up, but if you've
made the appropriate sacrifices to the wireless gods before starting,
it usually works.

The downloaded manual says there is a reset button, however the D-Link
WEB site indicates the only way to reset is via the WEB interface. In
my case that is a chatch-22. The unit is mounted on a pole on the
roof, so it not readily accessable. Read that: "I don't want to climb
up on the roof if I don't have to."

That's what kids are for. Kids are ideal for suicidal repair jobs and
futile efforts. They don't know any better, are comparatively cheap
to hire, and are somewhat expendable. Of course, it might be easier
to lower the pole than to raise the kids, but I'll leave you with the
obvious decision. What's more important? Wireless connectivity or
the life of the neighbors obnoxious brat?

If undecided, I suggest the software reset route.

Any hints as to gaining access would be appreciated. TIA

Is the system currently working and functional? If so, an IP scanner
will find the device. The DWL-2600 MAC address starts with 00:15:e9
so that should help. I suggest the command line version of NMAP at:
<http://nmap.org>

Running NMAP on my office network:

C:\Nmap>nmap -sP 192.168.111.*

Starting Nmap 4.01 ( http://www.insecure.org/nmap ) at 2008-06-21

Yeah, I know it's an old version. There's also a Windoze version that
is probably easier to use, but I'm too lazy to try it.
