Resolve Getting 169.254.X.X (APIPA) Windows Automatic Private IP Address

When a Windows computer failed to get valid IP address from DHCP server, OS will automatically assign a Windows generated Automatic Private IP address called APIPA to it. This automatic Private IP address is in the range 169.254.0.1 to 169.254.255.254. In a nutshell we can say any IP address in the range (169.254.X.X) is APIPA and it shows your computer is not connected to any network. Since APIPA (169.254.X.X) is a private IP address, your computer will not communicate to any other computers connected in the network(connected to a DHCP server). If you want your computer communicate to other computers in the network, you must change 169.254.X.X IP address by fixing the issues which prevent your computer from getting a valid IP address from DHCP server. This tutorial explains major reasons to get APIPA and how to resolve it.

APIPA = Automatic Private IP Addressing

All Windows versions like Windows 8, Windows 7, Vista, XP etc support APIPA except Windows NT. Follow the instructions belo…

Simple Guide For Router To Router Cascading

When you extend your current network, you may need to add more routers to the existing network. Without knowing how to perform router cascading, you will fail to add extra router to the network successfully. In this tutorial you will learn how to connect extra routers to the current network by cascading routers without having any network issues. There are two ways to cascade a router to another router. Before configuring the second router for router cascade, make sure that it is not connected to the main router (where the broadband modem is connected).


Different Methods to Cascade Two Routers LAN to LAN Router Cascade

Connecting one of the Ethernet ports (LAN ports) of the second Router to one of the Ethernet ports (LAN ports) of the main router. In this method, the devices connected to the second router and the devices connected to the first router are in same network and can communicate each other directly.

WAN to LAN Router Cascade

Connecting the Internet port (WAN port) of the sec…
