I have been using a little Webstar modem and just bought a Motorola SB4220 modem to replace it. I can't get it to work. I did not receive an installation CD with the modem. I am hooking it up with a coaxle cable to the modem from the wall and an ethernet cable from the modem to my computer. I am running windows xp. I downloaded drivers but it will still not work. Do I have to have the CD in order to get it to work.

Depending on how you set up the first computer, you can have one computer connected by USB and another by ethernet (straight-through cable). If you want both computers connected by ethernet, you need a crossover ethernet cable between the Modem and a router or switch (hub). You will need a straight through ethernet cables from the router to each computer.
You may want to have the modem working with your system first and hook up your router after wards.
Disconnect your router and modem.
Reboot your system.
Run your hard wire direct to your SB4220 from computer net card.
Allow to load whatever drivers necessary.
On your computer type ipconfig /all This will show you all your information.
Try the internet and see if it works. If you know the ip of your carrier, Type ping ????? ie: Ping comcast.net
If you recv. a timeout you still have problems.
If you succeed, you are their.
If not, type ipconfig /renew This will reset your ip and configurations.
Now, hook up your router and you should be their.
it sounds like you have configured the router correctly. what you might be doing wrong is trying to access the camera from your internal network using your external ip address. this will not work... you need to get someone on the "outside" to try the ip address.
Make sure that you have the ethernet cord from your modem plugged into the WAN/Internet port on your router. Then unplug the power cord from your cable modem and plug it right back in. After the modem fully comes back online, unplug the power cord on the wireless router and plug it back in. wait 30 - 60 sec and then try and connect.
Most cable companies only allow one active"CPE" at a time for internet access. All this means is when you change what is connected to the cable modem you must always reboot the cable modem to allow access.
