I wish I knew enough about wireless connections to be able to help you out. Unfortunately, I've never really worked with any wireless hardware (apart from one mouse that was so finicky that I eventually recommended that the person replace it with a corded mouse).
In one of your previous comments, you say "since the format". Does this mean that you have formatted the PC with this wireless issue? If so, what operating system have installed on it? Are the correct drivers installed for the wireless components?
Additional points to consider: If these wireless components were working fine for (whatever period of time they were working fine for), and they only started to exhibit this behaviour recently, then either 1) something has started to interfere with their signal (test the PC and its wireless components in a different physical location, like a friend's house), or 2) the wireless components have suffered a problem, or 3) the motherboard's wireless support has suffered a problem. Those are the only possible variables (since you've eliminated the software and the operating system by formatting... unless 4) new driver software has been released recently for those components, and was automatically downloaded and installed on your previous operating system and your newly installed operating system).
As for wireless monitoring software, you might want to download this 2.7mb utility to "monitor the status of wireless WiFi adapter(s) and gather information about nearby wireless access points and hot spots in real time":

Don't let this issue get to you bud, we'll get it sorted out. Separating the possible causes into the four points above may help in being able to isolate the root cause.
