Hi buffy1,
I have linked two article at the bottom of my post that show how to connect your TS6420 to Wi-Fi, if my steps are not clear.
To connect your PIXMA TS6420 to your Wi-Fi, please follow these steps:
1. From the Home screen, please press the OK button on your TS6420 one time.
2. Repeatedly press the down arrow to select Wi-Fi setup and press OK.
3. Repeatedly press the down arrow to select Manual connect and press OK.
4. Select your home's Wi-Fi network name and press OK.
5. Next, please input the password.
Below the password input box, you will see an icon with two interlocking circles and a A 1 @ to the right of it.
Currently, the a is selected. If you need a capital letter or number instead, press the interlocking circle button on your printer until either A (for capital letters) or 1 (for numbers) is selected.
To input a letter or number, press the up or down arrow.
Once you have selected the desired letter or number, press OK. That will bring you to the next position so you can then select your next letter or number.
6. When the whole password is entered, press the Start button.
Your TS6420 will connect to your Wi-Fi.
