When the 192.168.1.3 IP address is assigned to a router, you can access it via its URL, which is always http://192.168.1.3. 192.168.1.5 is the fifth IP address on the 192.168.1.0 private network whose assignable address range starts at 192.168.1.3. The same address can also be used on business computer networks.The router has failed and is unresponsive to connections via the browser. This is often the case when using the ipconfig command. A device with IP address 192.168.1.3 dynamically assigned to it may be re-assigned a different address if it's kept disconnected from the local network for an extended period of time. Most networks assign private IP addresses dynamically using DHCP. Attempting to assign 192.168.1.3 to a device manually, like you read above, is also possible.The only other time most users see the 192.168.1.3 IP address is when checking their own device to see what IP address is assigned to it. Even after the DHCP lease expires, a device is likely to still receive the same address the next time it joins the network unless other devices have also had their leases expire.Other common router addresses are 192.168.0.1 and 192.168.2.1, but there are too many possibilities to guess them all. The characters"192.168.1.3"or the four numbers - 192, 168, 1, and 1 must be keyed into a configuration screen on the unit.Network troubleshooting steps should be followed to determine why a router set up at 192.168.1.3 is not responding. The length of time, called a lease period in DHCP, varies depending on the network configuration but is often two or three days. In other words, if your network is using the 192.168.2.x range, for example, setting up one device to use the static IP address of 192.168.1.5 will just make it incapable of communicating on the network, and thus will not work with the other devices. This is often the case when using the ipconfig command. However, simply entering the IP number does not guarantee its validity on the network since the router must also be configured to include 192.168.1.3 in its address range. The same address can also be used on business computer networks.
