Try a wired connection.
Got this from a forum:

The error ce-33987-0 indicate a network timeout. You should troubleshoot your network to try and resolve the issue.
Troubleshooting a wired connection:
Ensure that the modem uses an Ethernet connection, not a USB connection.
In some instances, it is necessary to restore the PS4 system’s default settings before establishing a network connection.
Ensure that all network equipment is correctly configured and that all cables are functioning correctly (if in doubt, try using different cables).
Ensure that all network equipment firmware and drivers are functioning and up to date.
Check that the wireless access point (usually a router or hub) is functioning correctly by attempting to connect the PS4 system directly to the modem.
If the problem persists, check if other devices can connect to the network. If not, there may be a problem with your Internet service. Contact your Internet service provider for more information.
Troubleshooting a wireless connection:
Ensure that all network equipment is correctly configured and supports 802.11b or 802.11g wireless protocols.
If your wireless network is secure, ensure that the WEP or WPA security key is correctly entered.
Ensure that all network equipment firmware and drivers are functioning and up to date.
If your wireless network is MAC filtered, ensure that the PS4 system’s MAC address has been correctly entered in the MAC filter table as a permitted device.
If the problem persists, check that other devices can connect to the network. If not, there may be a problem with your Internet service. Contact your Internet service provider for more information.
