Dual-Band Wireless A+G Broadband Router selects the right access point and registers its address. Communications between end node and host computer can then be transmitted up and down the backbone. As the user moves on, the end node’s RF transmitter regularly checks the system to determine whether it is in touch with the original access point or whether it should seek a new one. When a node no longer receives acknowledgment from its original access point, it undertakes a new search.
Dual-Band Wireless A+G Broadband Router practical purposes, this number is usually permanent. Unlike IP addresses, which can change every time a computer logs onto the network, the MAC address of a device stays the same, making it a valuable identifier for the network. How do I reset the Router? Press the Reset button on the back panel for about five seconds. This will reset the Router to its default settings.
Dual-Band Wireless A+G Broadband Router Appendix B: Wireless Security Linksys wants to make wireless networking as safe and easy for you as possible.
