  1. Doing so will take you to your router's page. [8]
  2. Some routers are protected by a username and password. If you didn't set the password, you can usually find it in your router's manual. [9]
    • You can also look up your router's model number and name online to see if you can find the default username and password.
    • If you set a password but no longer remember it, reset your router to restore the factory settings.
  3. Each router's page will differ slightly from other routers; you'll likely find the router's settings.
  4. This will usually be in the "Network Settings" section (or your router page's equivalent). If you can't find DHCP there, look for it in the "Advanced" settings, "Setup" settings, or "Local Network" settings.
  5. Click the Enable switch, checkbox, or button. In some cases, you may first have to click a Disabled drop-down box and then select Enabled from the drop-down menu.
    • You may also have the option to change the number of devices that can use your router. Be careful if you do this, since allowing for too few devices will result in connection errors for one or more devices.
  6. Click the Save or Apply button to save your settings. Depending on your router, you may also be prompted to restart your router in order for the changes to take place.

    Can an iPhone be removed from a router without access to the actual device?

    Yes. Simply prevent the iPhone's Mac address or IP address from connecting to the router in the access control of your router settings.

    It should take 1-2 minutes for a router to reboot. It could take up to 5 minutes though, so don't be concerned if it takes too long.

  • Question
    I tried using admin and password to log into my router, but it won't let me in. It asks for city I was born in and father's middle name. I input the info, and it says that the info is not correct! What should I do?
    R2_d2000
    Top Answerer
    I sounds like someone else set up your router, but didn't give you the information. You will have to reset your router back to factory settings. There should be a reset button on the back of the router. You can push it with a paperclip, and hold it down for about 30 seconds. This should reset the router.
