The problem with Windows 7 is finally solved. I was unable to get it connected to the Internet after I installed Windows 7. The modem showed cannot find connection port, or failed to connect to the Internet. Changed to XP compatible mode didn’t help, neither it works after I upgraded the modem firmware.
Perhaps I don’t know how to use Google properly, I just couldn’t find any answer to the problem. No broadband means no life to me (freakin’ net addict I’m). So, after some tried and error, I finally made it to work - by creating a new Dial-up connection under Connections tab in Internet Options. Set the Phone number to *98# and leave everything else as default. That’s it! (Yup, it’s Celcom Wireless Broadband number. I’m using it when I’m away from home).
The PROLINK 3G Modem PC Manager will “work together” with the newly added Dial-up connection. Why is it that way? Why can’t it work by itself? That, I have absolutely no clue. Due to Windows 7 is still a RC version, maybe? But as long as I can get my netbook connected to the Internet when I need it while on the go, I’m a happy man.
