2. Check 2 Are the wireless router and printer installed in an open space where wireless communication is possible?

3. Check 3 Check your wireless router's network name (SSID) and password, including case sensitivity. Note that a password is required after selecting a wireless router.

   Network names (SSIDs) may differ between the 5 GHz and 2.4 GHz frequencies. They may also differ between when the security protocol is WPA3 and when none or WPA/WPA2 is set.

   Write down or take note of the network name (SSID) described on the wireless router, and then check the name, including case sensitivity.
