"A wireless router with the network name (SSID) you entered was not detected." Appears

1. Check 1 Is the wireless router turned on?

   If it is already turned on, turn it off, and then turn it back on.

   Do not proceed to the next screen of this guide until the power is turned on. The connection to the wireless router will be temporarily disabled.

   Check the above and press the OK button.

   After that, return to the previous page, enter the correct network name (SSID) in the printer screen, and then press the OK button.

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), including case sensitivity.

   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.

   Check the above and press the OK button.

   After that, return to the previous page, enter the correct network name (SSID) in the printer screen, and then press the OK button.

4. Check 4 Check that the security protocol is the same between the printer's Wi-Fi and the wireless router.

   Normally, there is no problem as long as the security protocol is set to something that includes WPA2.

   If "IEEE802.1X/EAP (WPA/WPA2/WPA3 Enterprise)" is set on the wireless router, change it to "WPA/WPA2/WPA3 Personal." This printer does not support "IEEE802.1X/EAP (WPA/WPA2/WPA3 Enterprise)."

   The wireless router's network name (SSID) is normally described on the wireless router; for details on the security protocol settings, see the manual supplied with the wireless router or contact its manufacturer.
