Cable modem & Router won't play together

Dlink has toll free technical support at 1-877-453-5465 24 hrs/7 days. They should be able to help you since it is their router.

Yes well, since the XP boxes work fine alone, it's not an XP problem either.

Look at the router DHCP settings. Make sure both the boxes are using ip addresses within the DHCP scope (or if using manual ip addresses on the computers, make sure they are in the same network and subnet).

Make sure that your gateway settings on the XP computers, point to the router.

Make sure that the computer account resides in the router. Make sure that all the settings currently residing on your computers is in the router. See if you can get one XP box on the Internet through the router... then work on the second.

It sounds as if the computers are properly setup, and that cable works fine but when the router is in place... that's the problem. Which probably means that it's either a bad router or that something is not properly setup in the router.

Something is missing from the router setup -- but I do not know enough about the model you have in order to point you in the right direction. Nor do I know enough about how cable works (I use DSL).

Call d-link back and tell them that the problem is either networking or the router setup. Tell them it works fine when one computer access the Internet directly through the modem. If they cannot help you, then have them escalate the call to someone who can. You should also try their corporate offices in California (949 area code according to their website) if you get no resolution from the free-technical support site.

Sounds like a common simple talk and listen problem.

The cable modem and the router are simular devices.

your network cards and cable modem or router should show link lights when plugged directly to one or the other.

But I'll bet you dont have a link from the router to the Cable modem when you plug them in to each other?

the reason is that the cards are set to use a straight thru cable

You need a cross over cable to connect like devices.

In order to create this you need to hold a RJ45 so the gold pins face you. that makes the pins 1-8 and follow the color code I tell you.
connector 1
1 White Orange
2 Orange
3 White Green
4 Blue
5 White Blue
6 Green
7 White Brown
8 Brown
connector 2
1 White Green
2 Green
3 White Orange
4 Blue
5 White Blue
6 Orange
7 White Brown
8 Brown
This gives you a Cross Over Cable the cables you are using are straight thru and the one you have linking the router to the modem more than likly has all pins coded the same on both ends (straight cable)

Hope this helps

This may not apply but I had a friend with a DSL and had a simular issue turned ot to be a interconnect somewhere down the line.

Standard rolls of Cable are 1000 feet and are spliced or terminated with a green box or a large black or silver can at every 1000 feet or as needed and when this splice is made the elemts then can degrade it and cause a poor connection wind blowing earth shifts or rain and other contaminents then affect performance. You have to convince teh Telco that it is in their Lines and to go and find the needle. This took him about 2 months to accomplish now he is 24-7 365 178Mbs not that this is what you are experiencing but these lines the Phone Company uses are old and reused until the lines just wont work.

If you follow the directions in the router box, it should work "right out of the box" with possibly one or two default setting changes (listed in the doc).

This may sound too simple, but it happened to me.

I spent weeks, with my router supportpeople and many very smart network people, nothing worked.

The router people finally gave up and replaced my router. The new one worked "right out of the box". I felt so dumb.
