Sony VAIO P Corel InstantOn wireless issue

In v1.0.1, looks like the Instant Mode's (Corel InstantOn) wireless try to connect to access points at 1Mbps. The APs in our institute has 1Mbps and 2Mbps disabled, min. of 5 Mbps is required. It will fail to connect in this case. I have similar problem with the Nintendo Wii before, it has the same behavior. It works in the updated 2.0.4.
