Stable wireless Internet connections for most laptops are achieved when interference from the signals transmitted between the laptop and the network's wireless access point is minimized. Reconfiguring the wireless network itself to avoid interference also helps stabilize the wireless connections of a laptop connected to the network.
Interference between a wireless network access point and the laptop is caused by several factors, including intervening objects, other nearby electronic devices and signals from other wireless networks. The most stable connection to a wireless network is typically achieved when the laptop is positioned with a direct line-of-sight to the network's wireless access point. Wireless network signals become weaker further from the access point, so positioning a laptop as close as possible to the access point also helps to stabilize the laptop's wireless connection.
Modifying the configuration of the wireless network itself also helps stabilize the network's connection with a laptop. Changing the frequency channel that the wireless access point uses for communication often helps improve connection stability in cases where several different wireless networks are in close proximity to one another. Adding signal repeater stations that rebroadcast the wireless network's signal is an option in cases where a laptop needs to be used further away from the access point.
