Please support me.?

I face quite interesting issue. I had done connecting PC and PDA via wireless. I am using SOTI pocket controller software to display it. It success actually. But, one issue it push me to find out. Sometimes when i disconnect and connect back, that connecting just can be display about 3second only and nothing error occur after it. I need to try connect manytimes then it going ok. It that wireless have another setup to stable my connecting?
