Mobile Printing & Cloud Printing

I recently purchased this printer (OfficeJet 8710) and when I first hooked it up, the wireless functionality worked fine. The next time I tried to print something wirelessly, I couldn't. It had been disconnected from the wireless router somehow. I contacted support, and through 2 hours we tried multiple things including turning the printer on and off about a hundred times, and changing a setting on my router. Nothing worked and I ran out of time as I had an appointment. That evening, I tried to connect the printer again. I managed to make it work but I'm really not sure what I did. I think I finally got it to work through the app on my cell phone but I'm not sure. It worked GREAT for about a week, and then today, it refuses to work again.

It can find the router, but when I enter the password to sign in, it tries to connect for a minute or two, and then says "unable to connect to the network. For diagnostic information, touch "Print Report."

It prints fine from the pc, but I can't get it to connect to the network so that I can print from my cell phone or laptop, both of which worked find last week. As far as I can tell, nothing has changed.

I also downloaded the troubleshooting program and nothing there worked either.

For the diagnostic results, they say:

Also, it has a suggested soluction with is that I need to disable MAC address disabled, but it's already disabled so it can't be that.

Any ideas?
