imageCLASS LBP246dw Won't Connect to Wi-Fi

[wtansi]

I have a Canon ImageClass LBP246dw printer connected using Wi-Fi.  It was working fine until I got a new router.  I can't connect it to the new one.

I can find the network in Wireless LAN Settings.  But, when I enter the password it tells me: "Could not connect.  Check the encryption key settings."??

Thanks Tiffany,

I didn't include my computer OS because that really plays no part in the communication between the printer and my network router. Although, I supose I could have provided more details about the router itself. So, point taken.

Question: The response from shadowsports wasn't, in and of itself, the solution to my problem. However, I certainly credit them with pointing me in the right direction so I could find the solution. Is it correct for me to click "Accept as solution" on that post?

Greetings,

Please log into your router and confirm its network settings. 

The printer requires a 2.4 GHz broadcast that supports WPA2 encryption.  

If your network is configured to use the same SSID name for all broadcasts or a different encryption methods such as WPA3, the printer could have difficulty or fail to connect.

Thanks for your response, shadowsports.

I do have both 2.4 and 5 GHz frequencies using the same network name. (Both using WPA2-PSK (AES) security mode.) I tried disabling the 5 GHz frequency and the result was the same. Except the message said check the security settings, instead of encryption key.

However, while I had the 5 GHz freq. disabled, I tried connecting from my iPad and was told the password was incorrect. Whether that was true (I have my doubts) or the router had a hiccup, some combination of restarting the router and "replacing" the password fixed the problem.

Thanks for pointing me in the right direction!
