Can't get router to work after disconnection.

All the solutions refer to a modem. I don't have one. When I changed cable carriers for TV. my telephone and internet provider

hooked me up to their cable. The cable is hooked up directly to the

router and they took away their modem.....said I didn't need it. All worked very well until I had to disconnect it. I couldn't get it hooked up correctly because I couldn't remember my network name or whatever so I hooked the cable directly to the TV and used that until I had more time to try and do it correctly. Of course, I had no wireless access to the internet for my laptop. Strange, though, when I turn on the wireless access on the laptop it shows the name of my network and that it has a strong signal but when I try to log on the internet it is unable to complete the connection.

When I called my internet provider they couldn't or wouldn't help me saying that their system does not show that I have I router. They told me when the power was turned off to the router the identity was lost and that I would have to reset it. When I called D-Link they told me to insert the original CD which by the way I no longer have. My son-in-law said I didn't need it anymore. I do have all the info used in the original installation such as "My Network Name (SSID), "My Security Key" and "My Password" but I can't get to that part that may require this info as shown as an example

on their web page.

I told you I was a computer ignoramus. It's so bloody frustrating I am ready to take an axe to the whole bloody works.

My son-in-law helped me once before but I can't contact him right now.

HELP!!!!!

How many computers are connected, or were connected to the router, is it wireless? How many computers are connected, or were connected to the router, is it wireless?
