Hi Kathy Koch,
For the HP ENVY 6400e, the easiest approach is to use HP Smart to complete the wireless setup and connect the printer directly to your Wi‑Fi network.
You can try these quick steps:
- Install the HP Smart app on your PC or mobile device.
- Turn on the printer and place it near your router.
- Open HP Smart and select Add Printer.
- Follow the on-screen prompts to connect the printer to your Wi‑Fi network.
- Once setup is complete, print a test page to confirm the connection.
If the printer does not appear in HP Smart, you may need to place it in Wi‑Fi Setup Mode first. HP's setup guide for the ENVY 6400e can provide the exact button combination for your model.
I hope this points you in the right direction. If you run into any specific error messages or the printer cannot be detected during setup, please let me know the details and I'll be happy to help further.
