Check Security Settings

Greetings everyone,



     I am having trouble connecting my Canon Color ImageClass LBP622Cdw printer to my router. It was working fine until a few days ago and now I cannot reconnect. It's finding the router, but when I put in my key it keeps telling me it cannot connect and to check security settings. I have no idea what that means (I'm not that tech-savvy). Any advice?

Re: Check Security Settings


The printer supports connection to a 2.4Ghz wireless broadcast;



It supports these security standards:


Wi-Fi Infrastructure Mode: WEP 64/128 bit, WPA-PSK (TKIP/AES) WPA2-PSK (AES)
Wi-Fi Access Point: WPA2-PSK (AES)


You'll want to use WPA2-PSK (AES).  Any Wi-Fi 5 class router will support this. 


Set up instructions are here (windows). If you have a MAC, let us know.

I have a MAC, but it seems the printer won't let me connect to the Verizon Fios router (even though it used to be connected to it).
