MX490 says its connected but won't print wirelessly

[alexthewhale]

I have a Canon MX490 and it will connect wirelessly to our wirless network using the button on our modem. The printer itself will then say it's online but when I try to print from my computer, the computer says its offline. i've tried restarting both without success. When I first installed the printer/software it printed well but has since gone offline and not come back. I'm using MacOS Sierra. Thanks!
