If all steps fail, please send your PS4 to the service center to check your LAN port if it is for repair. What is really connected on the Host side is something a Guest will never see, wireless or otherwise. If step 5 failed, go into Safe mode Initialize your PS4. vbox4me2 wrote:You are confusing yourself with the LAN connection on the Host and a Guest, they are not the same, a Guest LAN is emulated with also a emulated connected cable.Go to safe mode and do a Rebuild Database, then test.Check modem or router configuration if your PS4 Ethernet MAC address is set to static or your Ethernet MAC address is block.It is also possible that your cable is damaged. Some ISP disabled it via firmware update with the customer knowing. Call your ISP, your modem LAN port 2 and up might be disabled.If the issue persists and you are using a laptop, you may battery drain the laptop and afterward, check if the issue is resolved. You can find out the name of your network card using 'ifconfig' or 'ip addr' commands. Then connect back the power cable to your system (in case of a laptop, put back its battery) and power on the system to check if it is clear of the network adapter issue.

It is possible that the Lan ports could be disabled or faulty. As you in the above outputs, the network cable is connected with the Lan adapter.

Reconnect your ethernet cable to your PS4 LAN port and reconnect the ethernet to the modem router starting from the LAN port number 1 then increment when it does not connect.

If you could connect to the modem, this indicates the ethernet has a problem.

Test your connection, by using the guide below. “CE-33984-7 PS4 error” may also appear when your PS4 ethernet has a problem communicating with the modem router.
