I cannot connect my new HP Smart Tank7600 Series to my WiFi. It sees my WiFi but will not connect. Gets almost there, then tells me it is unable to connect and gives me an -9 error code.

Welcome to the HP Community --
Check the connection frequency.
Connect the printer to the SSID named network you want it to use (either 2.4GHz or your 5GHz).

HP Printers - Using a Wireless Network Test Report
Sample
Product Specifications for the HP Smart Tank 7606 All-in-One (28C03A)
When the printer is on the network to the extent that you can reach it using the IP address,
Consider using the Embedded Web Server (EWS) to configure the SSID details.

Example – EWS – IPv4
EWS > HP Document / How-to
Use the HP printer Embedded Web Server (EWS)
NOTE: Find printer IP address
Section Open the EWS over a local network orientation
Ethernet
Open your Browser > Type / enter the Printer IP address into URL / Address bar
Tab Network > Wired (802.3) > IPv4 Configuration
Wireless
Open your Browser > Type / enter the Printer IP address into URL / Address bar
Tab Network > Wireless (802.11) > IPv4 Configuration
As Available:
Tab Network > Wireless (802.11) > Advanced
Network Interface on / off, Network SSID name, Security Settings, Passphrase / Password
Select and connect to the correct SSID / network name for the bandwidth you are using.
Note: It is not mandatory that you use a manual / static IP address. Doing so can improve stability.
Example “Alternate” EWS format (new printers)
Open your Browser > Type / enter the Printer IP address into URL / Address bar
Section Network > Primary Ethernet > Check / Adjust Status and other tabs...

Dual Band Network - Considerations
Reminders
Do not ignore your router --
A router that is weak, outdated, poorly located, or incorrectly configured can cause all sorts of odd network behavior issues.
If the printer supports it, connecting using Ethernet is generally a better choice.
Wireless
Some printers, particularly older models, only support Wireless at 2.4GHz
Some printers support Wireless at both 5GHz and 2.4GHz – but not at the same time
Regardless, if the printer won't work or cannot connect to your 5GHz SSID named network, connect to the 2.4GHz network.
If you are running a Dual Band Network,
Check that the router is set up to broadcast all frequencies it supports.
Next,
If your router supports it,
On your router:
Create a separate SSID named network for each frequency supported by the router
What? Create one SSID named network for 5GHz and one SSID named network for 2.4GHz
and
Connect the printer to the SSID named network on the frequency / band you want it to use.
In general,
- 2.4GHz is less fussy about obstacles and supports a longer distance (separation) between router and device (printer)
- 5GHz is faster
