I am developing a software on Windows Mobile that searches APs periodically. The software on smartphone returns information (including GPS position, and Signal Strength with certain interested APs) to another computer by WLAN, meanwhile it receives some controlling command from the computer. The problem is the network experience a stoppage every time the timer(to trigger the nearby AP searching) ticks. It is just a stoppage but disconnection, so I suppose the searching process occupates too much bandwidth. I'm wondering how to solve this issue, either by increasing searching process (by using Refresh()? but it doesnt work here...) or confining the range to those SSIDs that are in the interest somehow?
