  5. Press the Power button on your PS5 to power it back on.

Following the process above will cause both the hardware and the software components of your PS5 to re-initialize, sometimes automatically solving minor problems without requiring further troubleshooting.

Power Cycle Your Router

Since it’s entirely possible for the problem to be router-related as well, it’s often a good idea to power cycle your router before moving forward with more demanding troubleshooting steps, which is another quick and easy process that you can go through in no time.

To power cycle your router, you can follow the steps we have outlined below:

  1. Power your router off by pressing the power switch or button.
  2. Unplug your router from power.
  3. Wait a minute or two with the router unplugged from power.
  4. Plug your router back into power.
  5. Power your router back on by pressing the power switch or button once again and wait for it to initialize.

Following the process above will cause prompt your router to re-initialize your home network and its connection to the Internet, which can lead to minor connectivity issues being automatically resolved.

Disconnect the Ethernet Cable on Both Ends and Reconnect It

Disconnecting the ethernet cable from both your PS5 and the router and then reconnecting it will allow the link between the two devices to be re-established while also making it possible to ensure that the cable is correctly connected to the Ethernet ports and that it’s not damaged.

For this solution, start by removing the connector from one device first, followed by the other, gathering the cable, and placing it in an area where you can inspect it.

Once you can see the entirety of the cable, examine it and the connectors that are attached to it for any signs of damage, such as kinks on the cable, exposed wires out of the cable jacket, loose connectors on either side and wires coming out of the connector.

After confirming that the Ethernet cable and its connectors don’t have any visible issues, proceed with plugging the connectors back into your PS5 and your router while ensuring that they are fully pushed into the Ethernet port.

As Ethernet connectors and ports have a system where the connector locks into the port once it’s connected correctly and only can be pulled out by pressing the tab down, you can verify that everything is in order by giving the connector a soft pull, and observing whether it moves or wiggles.

Switch the Ethernet Cable to Another LAN Port on the Router

Considering that a malfunctioning LAN port on the router can easily be the culprit behind the Internet connectivity issue you’re facing on your PS5, even when everything else is working as intended, switching the port is definitely a solution worth trying, especially considering how simple of a process it is.

For this process, all you will need to do is to unplug the Ethernet connector from the LAN port that it’s connected to on your router and plug it into another one, as most routers come with multiple LAN ports that are placed right next to each other.

One thing to watch out for when applying this solution is to ensure that you aren’t plugging the cable into the WAN port on the router, which is usually also located next to the LAN ports and can be hard to distinguish due to it practically also being a standard port that accepts an Ethernet cable.

Set the Internet Connection up Again on Your PS5

In some cases, something as simple as setting the Internet connection up again on your PS5 can solve the connectivity problem you’re facing, as this process will cause your PS5 to remove the pre-existing data about the connection and set it up again.

Below, you can find a step-by-step guide for setting up the Internet connection of your PS5:

  1. Open up the PS5 dashboard by long pressing the PlayStation button.
  2. Navigate to the Settings section by selecting the cog icon on the top-right of the screen.
  3. Navigate to the Network section.
  4. Navigate to the Settings section through the left pane.
  5. Choose the Set Up Internet Connection option.
  6. Select the wired connection from the Registered Network section, and press the Options button on your controller.
  7. Choose the Forget option from the dropdown menu, and confirm by pressing OK.
  8. Choose the Set Up Wired LAN option from the Networks Found section.
  9. Press the Connect button.

Please note that this process will erase the pre-existing wired connection information on your PS5, such as a manually inputted IP address or DNS server.

Manually Assign a Static Local IP and DNS Server to Your PS5

Your PS5 not being able to receive a local IP from your router due to a DHCP error is another factor that can prevent your PS5 from establishing a connection with your router, leading to the occurrence of the “LAN cable not connected” error that you’re seeing on your screen.

Below, you can find the steps we recommend following to manually assign a static local IP (and DNS server) to your PS5:

  1. Open up the PS5 dashboard by long pressing the PlayStation button.
  2. Navigate to the Settings section by selecting the cog icon on the top-right of the screen.
  3. Navigate to the Network section.
  4. Navigate to the Settings section through the left pane.
  5. Hover over the wired connection from the Registered Networks section, and choose the Advanced Settings option from the dropdown menu.
  6. Choose the IP Address Settings option, and choose Manual from the dropdown menu.
  7. Input the IPv4 Address, Subnet Mask, Default Gateway, Primary DNS, and Secondary DNS fields accordingly.

If you don’t know where to start to find the appropriate values, here is a quick guide you can use:

  • Subnet Mask – This value is 255.255.255.0 by default for a standard home network. You can get more information from your router’s interface.
  • Default Gateway – This is the IP address you use to access your router’s interface page. You can usually find this IP address on a sticker under your router or by checking the connection information (such as ipconfig on Windows) through a connected device.
  • IPv4 Address – This is an arbitrary IP address that falls into the IP range of your home network and isn’t already occupied by another device. To ensure that another device doesn’t use this IP address, you can check the router’s interface for the IP addresses of the connected devices.
  • Primary / Secondary DNS – You can use the DNS servers of your choice for these sections, with OpenDNS being a good option if you don’t have any particular DNS servers in mind.

While not a necessity, you can also add your PS5’s MAC address and the static IP you would like to give it in your router’s interface, which will ensure that an IP address conflict can never happen.

Enable the UPnP or DMZ Setting of Your Router

While they aren’t the same thing, enabling either UPnP or DMZ serves the same purpose of allowing your PS5 to open any port that it requires for a successful connection to the servers, which can potentially resolve the connection problems you’re facing.

Even though the exact process of enabling UPnP will vary across different routers, you should easily be able to find this setting by logging into your router’s interface.

When UPnP is enabled, all the devices in your home network, including your PS5, will be able to open any ports that they need for a connection dynamically.

On the other hand, to enable DMZ and put your PS5 into it, you will need to find the DMZ setting in your router’s interface and specify the local IP of your PS5 as the DMZ server.

Note that you will need to allocate a static local IP to your PS5 for DMZ to work as intended, as this will ensure that the IP address you have specified to be the DMZ server always belongs to your PS5.

Unlike UPnP, which allows all the devices on the network to dynamically open any ports they require, DMZ will automatically open all the ports from the get-go, but only for the device you have specified to be in the DMZ, which will be your PS5.

Please enable UPnP or DMZ at your own risk, as they are both considered features that can potentially introduce security risks to your home network.

Clear the System Software Cache of Your PS5

Clearing the system software cache is a process that removes the temporary files your PS5 has generated over time to make certain processes quicker, which can sometimes resolve minor software issues that stem from these files being corrupted.

To clear the system software cache of your PS5, you can follow the steps we have outlined below:

  1. Power off your PS5 by pressing and holding the Power button until the power indicator light completely goes off.
  2. Put your PS5 into Safe Mode by pressing and holding the Power button until you hear the second beep, which should occur 7 seconds after the first beep.
  3. Connect the controller to your PS5 with a USB cable.
  4. Press the PlayStation button on the controller.
  5. Navigate to the “Clear Cache and Rebuild Database” section in the menu.
  6. Choose the “Clear System Software Cache” option.
  7. Confirm by selecting the “OK” option.

While clearing the system software cache of your PS5 won’t cause you to lose your data, you may have to reconfigure some of the more minor settings stored in the cache.

Replace the Ethernet Cable With a New One

The last solution we recommend applying is to replace the Ethernet cable that connects your PS5 to the router, as this will allow you to rule out the potential scenario of the Ethernet cable itself being the culprit behind the issue.

When purchasing a new Ethernet cable, our primary recommendation would be to go for one that is Cat 5e or higher (assuming that you have a high-speed internet connection) from a reputable brand and seller, which will ensure that you don’t face any potential issues related to the cable, both in terms of speed and quality.

While not much should technically go wrong with an Ethernet cable, purchasing a cheaper one can sometimes result in the cable malfunctioning due to poor manufacturing quality and send you down another rabbit hole of troubleshooting.

Conclusion

While the “LAN cable not connected” error is definitely not something you want to come across on your PS5, especially if you prefer to play multiplayer games, you should most likely be able to solve the problem at home without having to send your PS5 in for a repair.

To summarize, let’s quickly go through the solutions we recommend applying to fix the “LAN cable not connected” error on your PS5:

  • Power cycle your PS5 to resolve any minor connectivity issues that can arise from the PS5’s operating system.
  • Power cycle your router to resolve any minor connectivity issues that can arise from the router.
  • Disconnect and reconnect the Ethernet cable to ensure that the connectors are correctly seated in the ethernet ports and that the cable is not damaged.
  • Switch the Ethernet cable to another LAN port on the router to rule out the possibility of the particular port creating the problem.
  • Set the Internet connection up again on your PS5 to reset the related information and re-initialize the connection.
  • Manually assign a local static IP and DNS server to your PS5 to ensure that your PS5 can connect to the router, even if the DHCP server isn’t operating as intended.
