Make sure nothing is blocking the connection between your PS Link device and your PS Link USB adapter. Try connecting your PS Link USB adapter to a USB port on the front of your console* or computer.
Try moving your wireless router away from your PS Link devices.
If you have a wireless router that operates on multiple frequencies, please try disabling each frequency and testing your PS Link connection.
If other wireless devices are operating close to your PS Link USB adapter, remove them and power down the devices to see if the connection issues are resolved. Example devices include:
Smart home devices (outlets, lights, thermostats, etc.)
Try using a USB extension cable (sold separately) to place some distance between your PS Link device and potential sources of interference.
Try moving closer to your PS Link USB adapter to see if the signal quality improves.
If you’re using a USB 3.0 hub with additional high-speed connected devices (external hard drives, etc.), safely unplug the devices and see if the connection issues are resolved.
*PS5 consoles (CFI-2000 model group - slim) require a USB-C to USB-A adapter (sold separately) to connect to the front USB port.
