Blue light is blinking and printer won't connect to wireless

[Strickler2]

Printer had been successfuly set up and operational, but today the blue light is blinking, it won't connect to our wireless, and won't even print using the ubs. I have unplugged and plugged back in several times, and removed and re-loaded the software, but problem persists.

Power off router and printer. Power on router, wait 3 mins. Power on printer and see if it connects to the router.

Thanks. It worked after I also powered down my computer. 

Any idea what caused this to avoid happening again?
