Abstract

Disclosed herein is a method to method to automatically disable wireless LAN when the system is attached to a wired LAN. Wireless LAN function is becoming very popular feature among Notebook PCs. There are cases that these Notebook PCs have both wireless and wired LAN interface. Depending on LAN configuration, in most cases there is no need to use wireless LAN. If the user is accessing to only one network, there is no need to have two interface to access this single network. With the current most popular technologies, 802.11b(11Mbps) and 100M Ethernet, it is more likely to have better network performance over the wired interface. Also, with some OSes, such as Windows NT, you may encounter accessing the network when you dynamically plug/unplug the wired LAN interface because OS do not dynamically update the routing table. This invention will automatically disables wireless LAN interface when the system is attached to wired LAN. System will watch the wired LAN interface and when the system get connected to wired LAN, system will automatically disable wireless interface. Here is a sample of an implementation of this invention. RJ45

Automatic disabling of Wireless LAN when attached to wired LAN

    Disclosed herein is a method to method to automatically disable wireless LAN when the system is attached to a wired LAN.

Wireless LAN function is becoming very popular feature among Notebook PCs. There are cases that these Notebook PCs have both wireless and wired LAN interface. Depending on LAN configuration, in most cases there is no need to use wireless LAN. If the user is accessing to only one network, there is no need to have two interface to access this single network. With the current most popular technologies, 802.11b(11Mbps) and 100M Ethernet, it is more likely to have better network performance over the wired interface. Also, with some OSes, such as Windows NT, you may encounter accessing the network when you dynamically plug/unplug the wired LAN interface because OS do not dynamically update the routing table.

This invention will automatically disables wireless LAN interface when the system is attached to wired LAN. System will watch the wired LAN interface and when the system get connected to wired LAN, system will automatically disable wireless interface. Here is a sample of an implementation of this invention.
