I have an airport express and Win 7 pro. My router is a Trendnet TEW-423PI G. The problem is everytime i try to connect it says it is unsuccessful and can't find ip address. I have tried everything. WPA2, WPA, WEP, Messing with the registry, Manually Inputting the ip address, Reinstalling drivers. I have two Macs that connect perfectly and are both running Snow Leopard that is why I am able to post this. What Should I do. I'm Going Crazy
Have you double checked on the router if it has any security such as MAC filtering?
After this, I would double check that you have selected the right Encryption type (TKIP/AES).
Lastly, double check DHCP settings / as you said you did manual, make sure that the settings are correct.
I have seen your issue a few times when either one of the three above problems exist.. If you still have the problem, please say
If Wil's answer didn't solve the problem, have a look at the following article:

When I got my new computer with Windows 7 last month, I had the same problem, and went through the same steps you did. Here are two things that worked for me:
- Make sure you have the Security Type option for authentication correct: change from No Authentication (Open) to Shared or vice versa.
- Change the Homegroup name from whatever Windows assigned when you set up your connection to the network you assigned both your Macs.
