Wireless canon printers suddenly can't connect to wifi

[Delllap]

So I've got wireless canon printers and they've been working fine until today when I turned on the printer and the light that signifies the wifi connection wasn't on. It says the computer is offline. My other wireless printer says its connected but I keep getting error reports. I can only print if I connect a USB cable to the computer and printer. It happens on all the computers and I've tried restarting the network by unplugging it and everything. Any idea what's wrong and how to fix it?

FYI I have no computer/network knowledge whatsoever so I have no clue what's going on.
