I just recently purchased an hp laptop to use for world of warcraft on the go. When im home, i use a mac desktop and it plays wow great because it is connected directly into the 2wire router. for some reason though, the laptop can get internet access but it cannot play world of warcraft. i called blizzard and they gave me the port numbers that needed to be opened in the router in order to let the game work properly but for some reason when i added user defined applications under the laptops name in the router it still didnt work. AT&T wants to charge me $115 to fix this problem...and thats not happening. can anyone tell me what i need to do?

Try DMZPlus mode. I'm assuming you know how to get into your router because you configured user-defined ports, but just as a reminder the URL from inside your network is http://gateway.2wire.net/ and you need to click firewall. When you're in the firewall click "Firewall Settings" and enter your password. 1st select the right computer. BEWARE THAT IF YOU CONNECTED TO YOUR ROUTER BEFORE WITH THE SAME USERNAME, IT WILL LIST MULTIPLE ENTRIES OF THE SAME NAME! For example, if I had a computer two years ago named RYAN and I bought a new one, so I don't use the old one, and the new one also connects as RYAN it will list two different entries. If it does that you can go to Home Network at the top, which only lists the most recent connections, find the right computer, and click Edit Firewall Settings. Then move on to step two: Select radio button Allow all applications (DMZplus mode), which opens all ports to the internet for that computer, like skipping the router. Even though that's a little more dangerous, since you're more vulnerable, it will help you diagnose if opening the ports will solve your problem. Click Done and try to play your game. If it still doesn't work, call support again because opening the ports won't get you anywhere.
Good luck,

Perhaps you should mention what you're trying to do, exactly. If you need a port open for a specific application, then you need to go to the appropriate screen in your router's control panel (consult the documentation), designate a port number to be left open (consult the application), and tie it to the internal IP address of your laptop (consult your router's status or connection screen). Not as difficult as it sounds, but even for power users, this routine can get tiresome, especially if your IPs are all dynamically assigned. That's why you should enable something called "port forwarding" in the application if it supports it.
