If youre like most people, now days, your router offers 2.4 & 5gh capabilities. My phone is connected to the 5gs for obvious reasons. I tried everything I could to get this connect and it never found the printer. Then, I read a couple of reviews and someone mentioned they couldnt get it to connect to the 5 g connection but could the 2.4. I change my phone to 2.4 and the app recognized it immediately and worked without any issues.
So first and foremost connect to 2.4 and it should work great.
