I was wrong. No crossover ethernet cable is required to connect a
Speedstream 5200 to the WAN port of a DI-524. Please ignore my
comments related to requiring a different cable.
However, there is a potential complication with connecting a router to
a Speedstream 5200. The 5200 can be setup with internal NAT. The
easy way to tell if this is happening is to plug your computer
directly into the 5200, and then run:
start -> run -> cmd <enter>
ipconfig
If your IP address is 192.168.xxx.xxx, then the 5200 has internal NAT
enabled. At this point, methinks it best to call your ISP for
assistance.
The 5200 can also be configured with router firmware. See data sheet
at:
<http://subscriber.communications.siemens.com/subscriber_networks/5100.shtml>
Please determine which firmware you are using and whether you have a
DSL modem configuration or router configuration before continuing. The
setups are quite different.
Please make sure you can connect and configure your DI-524 with both
computers. Go to:
<http://192.168.0.1>
and check if you can see the web based configuration in the DI-524.
If you can do this, then go to the WAN or internet page. It should
look like this:
<http://www.support.dlink.com/emulators/di524_revD/h_wan_dhcp.html>
Do it with both computers.
At this point, I have no clue how to configure your DI-524 with your
efficient 5200, which itself can be configured in 3 different modes.
>I have to admit I have no idea what is a crossover cable.
If you inspect the connectors on both ends of a common CAT5 ethernet
connector, the wiring on both connectors will be identical. However,
some devices require that the transmit and receive lines be reversed
in order to work. For example, if you were to connect a hub or switch
to the LAN ports of a router, it would require either a crossover
cable, or an MDI/MDI-X switch on the hub or switch. You can tell if
you have the correct cable by checking if the corresponding lights are
illuminated. Also see:

The color of the cable means nothing.

That seems correct. The light in question here is the WAN light.
Since it is illuminated, I presume that the connection to the 5200 DSL
modem is correct. The cable or connection is not the problem.

>Not sure how to check this. Any suggestions?
Yes. Re-read what I wrote about checking the lights on the router and
the modem. When the cable between the router and the modem in plugged
and unplugged, the lights at both ends that correspond to the cable
should turn on and off. From your description of one side of the
cable, the corresponding lights are lit and therefore the cable is not
the problem.
>> Did anyone check the lights?
>All lights are mentioned above
The cable has two ends. The other end is plugged into the modem. What
lights are are on and off on the modem end? The light labelled
"ethernet" should be on.

Correct. It's probably not the cable.
Can you explain what program or where you are getting the "router not
detected" error message? This is not a typical Windoze error message.
I'm assuming that the connection between the computer and the DI-524
is via another CAT5 ethernet cable and NOT via wireless because light
#1 is turned on. Yet, you mention that you have two computers. How
is the 2nd computer connected? Wire or wireless?
My guess is that since the DSL modem by itself is functional, and the
DI-524 is apparently correctly wired, then the problem is on the WAN
(internet) configuration page of the DI-524 or in the various internal
configurations in the Speedstream 5200 modem. This is beyond my
abilities to handle remotely and will best be configured with the
assistance of your ISP or someone locally with some experience.
