LAN cable is not connected is a common issue that many PS5 users encounter when they try to play online games with other people. This error appears because your computer needs to be connected to a local area network (LAN) to connect to the internet. If you don’t have a LAN connection, you won’t be able to access the internet, which means you won’t play online games. Simply connect your console to the internet using a cable or WIFI to eliminate this error.
