Before the firmware patch I was tearing my hair out. I would turn off my router and be able to keep the printer on and use thru USB but whenever connecting to Wifi, it would have the same problem because of the DNS issue no matter how much I started over and cleared out the connections an re-installed drivers, etc.
I just applied the firmware update and everthing works now. Super duper annoying. I am so glad I didn't discover the problem until today however, when the patch got published. Other folks are in for a rude awakening when they power up their printers later on this year.
