Why it is needed: when at home or in the office several devices are connected to one access point, there is a chance to run into a conflict of IP addresses. It happens rarely, but it faces problems with access to the network. It is better to remember in advance the method of solution than at the most inappropriate moment to wool the Internet.

The problem can happen with any Apple gadget, especially if you use a non-branded router. Everything is fixed by updating the DHCP lease on the instructions below. Just a couple of clicks and the problem is solved.

Of course, you also cannot use already occupied IP addresses, since this will again lead to conflict. To fix this problem is quite simple. To do this, you just need to change your IP address. At the same time, you should follow the rules for assigning IP addresses that exist in your local network in order not to accidentally occupy an IP address used by someone else. In this case we will use DHCP technology.


  • Run “System Preferences” -> “Network”;
  • Select the current Wi-Fi connection or Ethernet and click “Advanced”;
  • In the TCP/IP section, click the “Request DHCP Address” button.


Often, these problems can be solved by restarting all computers (iPhone, Mac, etc.) in the local network. When restarting DHCP requests a lease. And your router should issue only those that are not used. Therefore, each device must receive a unique address.

However, it is possible that you manually assigned an IP address to one or more devices, so make sure of that. Make sure everyone is different and they are all on DHCP.

It is also possible that someone is undesirable on your network. Change your Wi-Fi password, just in case. Otherwise, all assign all static IP addresses like this.
