Solution
If the security on your router or access point is not one of
the following types, change the type of security on your
router or access point and reset your product's network
settings.
• WEP-64 bit (40 bit)
• WEP-128 bit (104 bit)
• WPA PSK (TKIP/AES); also known as WPA Personal
• WPA2 PSK (TKIP/AES); also known as WPA2 Personal
• WPA (TKIP/AES)
• WPA2 (TKIP/AES)
• WPA3-SAE (AES)
• WPA2/WPA3-Enterprise
Latin America: Also make sure you are connecting to the
2.4GHz band on your network and using the password for
that band.
If your router or access point has MAC address filtering
enabled, register your product's MAC address so it is not
filtered. Locate the MAC address on the network
connection report and check your router or access point
documentation for instructions.
If your router or access point is using shared
authentication with WEP security, confirm that you are
using the correct authentication key and index.
If your router or access point limits the number of
connected devices, raise the connection limit. See your
router or access point documentation for instructions.
