hpdeskjet 3700 can't connect to internet when router changed

[olyshed]

Tried to use a new Netgear RAXS router but had problems with other devices so elected to put the old router back which is an older TPLink - worked fine just wanted to upgrade.  Now the printer won't connect to network-tried everything. HP on line does not help me.  Where on the printer can I enter password name, etc,  I do not have a screen on the printer. HP Smart has my printer on the screen but states "unavaliable".  I'm not tech oriented so need very basic instructions,  Thanks for any assistance

Hi @olyshed,

Welcome to the HP Support Community.
 

Thank you for posting your query. I will be glad to help you.

You're doing a great job trying to reconnect your HP DeskJet 3700 after switching routers. Since this printer doesn’t have a screen, setup can be a bit tricky, but I’ll guide you through simple, step-by-step instructions to get it back on Wi-Fi.

Step 1: Reset Network Settings on the Printer

This puts the printer into setup mode so it can be discovered again.

1. Turn on the printer.
2. Press and hold the Wireless button and the Cancel button (the red X) together for 5 seconds.
3. Wait until the Wireless light starts blinking. This means it's in setup mode.

Step 2: Use HP Smart App to Reconnect

1. Open the HP Smart App on your laptop or iPhone.
2. Tap “+” to add a printer.
3. Select your HP DeskJet 3700 from the list.
4. Follow the on-screen instructions to connect it to your Wi-Fi network:
   • Enter your Wi-Fi name (SSID) and password when prompted.

If the printer doesn’t show up, make sure your phone or laptop is on the same Wi-Fi network and that Bluetooth is enabled.

Step 3: Confirm Connection

• Once setup is complete, the Wireless light should turn solid blue.
• Try printing a test page from the HP Smart App.

I hope this helps.

Take care and have an amazing day!
