It is handled by the OS and drivers for the wireless card. Many of the drivers have an option to set roaming aggressiveness under the properties of the card in device mangler. Making roaming more aggressive may help to alleviate low signal issues you encounter like poor speed and disconnects. Keep in mind that this will make the card more promiscuous however, and so it may switch between AP's more frequently. This may not be desirable depending on the effects it has on connectivity and your activities.
