HP Deskjet 2721 offline - I keep coming back to the same point of my printer being connected to the wifi but not online. I do not know how to get it to go online.

Hi @Kate1001,

I'd like to help!

To better assist you - 

1. Are you trying to connect your printer to your home network or public network?
2. What is the status of the wireless light on the printer, steady or blinking?
3. What device are you using the printer with, a Windows computer, Mac, Android or an iPhone? 
4.  I would like to know, is your router set to work on 2.4 GHz network or 5 GHz network band?

Let me know!

Hi Jay,

Thank you very much for responding I really appreciate it.

it's a home network

The status of the wireless network is blinking

I am using a Windows computer

The last question I am not sure but I believe it would be 2.4 GHz as it is slow
