How do I renew the PC’s IP address?

Go to Command Prompt, type “ipconfig /release” to clear all the network interface’s current configuration.

Type “ipconfig /renew” to obtain a new IP address from the DHCP server.


 
 
 
 
Alternatively, this also can be done by disabling and re-enabling your network adapter.

What should I do if I received an Automatic Private Address (169.254.x.x)?

Things you will need to do: 

1. Ensure the network cable is connected properly (wired connections)
2. Ensure that the router is has DHCP server function
3. Ensure that the PC is DHCP enabled
4. Renew your PC’s IP address
5. Restart the router and PC

1. Loose or damaged cables may cause un-wanted disconnections or trouble in communications between devices.

2. If the router has no DHCP server function, any hosts connected to the router will not be able to receive a DHCP offer IP address. User will need to set a static IP address in order to connect to the network.

3. If the PC is not set to receive DHCP (set to static IP address), and which may be different from the router's network, the 2 devices will not be able to communicate with each other.

4. If you are very sure that the router has DHCP service enabled and PC is also DHCP enable, but still cannot receive a correct IP address, you may wanna renew your IP address to receive a new DHCP IP address offer from the router.

5. If after all this settings still does not solve the issue, you may consider to restart both the router and PC.

What it means if I received an IP address of 169.254.x.x when connected to a router?

It means that either your PC is not DHCP enabled or the router’s DHCP server is not working properly.

169.254.x.x is an Automatic Private Address, which is a non-routable address and should not be used




If your PC is connected to a DHCP enabled router, the network adapter will be able to accept a DHCP offer IP address from a pool of available address from the router.

In normal scenario, a common private address issued by a DHCP enabled router will be 192.168.x.x

How do i check my PC's IP address?

You can access your PC’s network connection windows and check the details.

Alternatively, open Command Prompt
StartMenu --> Run --> type "cmd" (with out the "") --> Click "OK"

Type “ipconfig” (without the ""). It will show you the properties of all the network adapters available on the machine.

How do I test connectivity of my router?

You can 'Ping' between network devices to test the connectivity between them.

Open the Command Prompt window from the Windows start menu

StartMenu --> Run --> type "cmd" (with out the "") --> Click "OK"

You will see a DOS like window like this. This is the Command Prompt

Type "ping x.x.x.x" to check the connectivity, where x.x.x.x is the IP address of the network device that you want to ping.

A successful reply means the devices is connected.

A unsuccessful reply means the device may not be connected correctly, Or, there is no device connected with this IP address.




How 'Ping' works is actually to send a request to a specific host (or device) and wait for an echo to get to know if connection between the sender and receiver is OK.
