Thanks! That's strange, because I recently purchased a new modem/router. Our Internet was down for a while, and our ISP was lazy and consistenly refused to come over and take a look at the cable because somehow it was a "problem on our end." We replaced our router/modem twice, and purchased a much better Internet plan. After 2 months of us calling them almost every day they came and finally fixed the cable outside our house. Looks like I'm checking connections, port forwarding, and getting a new modem/router AGAIN. These people will drive me crazy....

Make sure the cable modem they provide you with is not ALSO acting as a router. That will screw up all your port forwarding. You can do this by checking your local IP address.you can do this in Windows by opening a command prompt (old school DOS prompt) and typing: ipconfig Note your IP address and default gateway. They should share the subnet mask. For the non networking geeks the numbers should be the same except after the last decimal. For example: IP: 192.168.1.101 Default Gateway: 192.168.1.1 If there is more difference than the last number, for example: IP: 192.168.1.01 Default Gateway: 192.168.[b]0[/b].1 That difference means the cable modem is still acting as a router and basically undoing any forwarding you do. If that is the case your ISP should be able to change your modem/router to just a modem. Or you can usually find a setting after logging in that tells it to act as a modem only (every company has a different name for the setting). You should be able to log into the modem just like your router by typing it's IP into your browser. Logins are typically: User: admin Pass: admin Sometimes they're on a sticker on the back. Or admin pass admin password admin 1234 [blank] admin admin [blank] Or any combination of the above .Call your ISP they will tell you and they can change the setting for you.
