I changed my internet provider. Tried my best to connect my printer but cannot do so. Need support.

Tried all instructions available. Unsure how to proceed.

Welcome to the HP Support Community!

Thanks for reaching out!

It sounds like your HP DeskJet 4100 is still "remembering" your old internet provider's credentials, which prevents it from seeing your new network. To fix this, we need to clear its old memory and put it back into "Setup Mode" so your devices can introduce it to your new Wi-Fi.

Reset the printer's network memory.
- Ensure the printer is turned on and at a "Ready" state.
- Press and hold both the Wireless button and the Cancel (X) button at the same time for five seconds.
- Release the buttons and wait for the Power button to flash and the blue Wireless light to start blinking.
Prepare your mobile device or computer for the new connection.
- Turn on Bluetooth on your phone or computer to help find the printer nearby.
- Ensure your device is connected to the 2.4GHz band of your new router (DeskJet 4100 models often cannot see 5GHz networks).
- Close the HP Smart app entirely and then reopen it to clear any old printer status errors.
Re-add the printer to your new network via the app.
- Tap the Add Printer button or the plus (+) sign in the HP Smart app.
- Select your HP DeskJet 4100 series when it appears in the list of available printers.
- Enter your new Wi-Fi password when prompted and wait for the blue light on the printer to stay solid, confirming it is connected.

You can find more detailed help in the official HP printer setup (HP Smart app) guide.

Is the Wireless light on your printer now blinking blue, or is it still showing a different pattern?

I hope this helps.

Take care and have an amazing day ahead! 🚀
