Internet access issue in Android 2.1 emulator (Windows 7 x86)

Anyone got this problem before?

In Windows 7 x86,

I created an avd which the target is Android 2.1.

It turns out that the emulator can not access the internet through the web browser.

But it works fine when the target is Android 2.2. I've tried to set the proxy. It just does not work in the Android 2.1 emulator.

1. If you are wirelessly connected to the internet

   Go to control panel and disable your LAN card

2. Home > Menu > Settings > Wireless Controls > Mobile Networks > Access Point Names

   Configure there

3. Try creating a brand new emulator

4. Try adding the followings params in "Additional Emulator Command Line Option" in Eclipse (Run->Run Configuration -> Target Tab)

   -http-proxy http://ip:port -debug-proxy (ip=proxy address and port=proxy's port)
