Connection via mobile wifi router

Is it possible for Android 2.2 tablet to access internet via wi-fi router (eg. HTC HD2 wm6.5)?. My Android 2.2 device can detect the access point but somehow unable establish a connection. Any suggestion will be greatly appreciated.

thanks fo the suggestion. i believe if the android tablet can detect the access point created by the mobile router, there should be a way to establish a connection.
