Many people don't like the hassle of assigning a static IP address to every PC on the network. The Dynamic Host Configuration Protocol, or DHCP for short, eliminates the need to do this by allowing it to automatically configure IP settings. This manual and the examples are based on the Qwest Actiontec Q1000 router. Other routers will differ slightly from this. but the standard procedure is the same for all routers.

Steps

Configure a Router to Use DHCP Step 1

Step 1. Launch a browser

Connect to your router by entering the IP address. This varies by brand and is stated in the router's documentation.

  • Here are some known IP addresses for different routers:
  • Linksys, 3Com, Asus, Dell, US Robotics: 192.168.1.1
  • Qwest (AKA CenturyLink), DLink, Netgear, Trendnet, Senao: 192.168.0.1
  • Belkin, Microsoft, and SMC: 192.168.2.1
  • Apple: 10.0.1.1
  • If you've lost the documentation and your router isn't listed, search Google for your router's name and "default IP address" to find the correct information.
  • Another way to find your router's IP address is this: On a PC, open Command Prompt (click Start > Run/Search for cmd) and type ipconfig. Find the line with Default Gateway, and try that number.
  • On a Macintosh, open the network control panel (System Preferences…, network) and search for router:

    This is the IP address of your router.

Step 4. If you want, you can change the number that DHCP assigns the IP addresses

This is optional and depends on your personal preference. If you're not sure what this is, it's completely safe to skip this step.

Some routers have the option to specify the maximum number of DHCP clients. If your router has this option, add up all computers, smartphones and other devices that use the internet (such as Apple TV). Add a few more for guests who come to visit and want to use their smartphones with the internet. When the maximum number is reached, no one else can get an address until another one is no longer used

Tips

Refer to your router's manual for instructions. This general guide should get you started in most cases. The basics are all the same, but the actual location of parts within the router software differs

Warnings

  • Make sure you have physical access to your network device in case you need to factory reset it.
  • Activating DHCP on an unsecured wireless network is something you should definitely not do. That way, anyone can connect to it and steal your bandwidth without any networking knowledge.
