What should I do if I see error code E-5 on my network connection report?

Error code E-5 indicates that the security mode (such as WEP or WPA) does not match the printer's current setting. If your router's security is not one of the supported types (WEP-64 bit, WEP-128 bit, WPA PSK, WPA2 PSK, or WPA3-SAE), you should change the type of security on your router or access point and reset your product's network settings.
