How To: Use your DIR-451 D-Link 3G Router with your Cingular/AT&T Option GT Max 3.6 PC Card
Steps:
#1 - Set up your DIR-451 as instructed by the quick install guide.
#2 - Access your router by opening a web browser and typing 192.168.0.1 into the address bar. Press enter. Log in using User: admin Password: (blank) (If you've changed your username and password from the defaults, then use whatever you changed it to to login.
#3 - Where it says "Manual Internet Connection options:" press the button called "Manual Configure"
#4 - Type in the following information:
ISP - Card: HSDPA - M1 - Vodafone GT MAX GX0201
User Name: ISPDA@CINGULARGPRS.COM
Password: CINGULAR1 (Yes, I believe it has to be ALL CAPS)
Server Name: isp.cingular
Dial Number: *99***1#
APN: isp.cingular
Everything else may be left as default. We don't need a keep-alive so don't mess with it.
#5 - Be sure to click "Save Settings" when you're finished.
Side note: Even though my Option GT Max 3.6 works fine and has plenty of signal strength when in my laptop, in the router it was only showing one bar and wouldn't even function. I stuck my external antenna on the GT Max and it works fine and says full strength.
