HP DeskJet 2755e All-in-One Wi-Fi Setup

The HP DeskJet 2755e All-in-One has a model-specific wireless setup path. Use the printer’s own controls and the current HP setup software rather than repeatedly resetting unrelated settings.

Set up Wi-Fi

1. Use HP's DeskJet 2700e wireless setup/HP app flow and place the printer in Wi-Fi setup mode when required.
2. Keep the setup device on the same normal Wi-Fi network and temporarily disconnect VPN if it blocks discovery.
3. If the router/network name or password changed, restore Wi-Fi setup mode and add the printer again.
4. If setup still fails, use HP's Wi-Fi diagnostics rather than repeatedly reinstalling unrelated print software.

If the printer is not discovered

1. Confirm the router is on and the phone/computer is connected to the intended network.
2. Temporarily avoid guest networks or VPNs that can block local-device discovery.
3. Check the printer’s network/WLAN status or connection report where this model provides one.
4. If the printer is already connected but one computer cannot find it, repair/re-add the printer on that computer instead of resetting the printer network first.

After changing router or password

Run this model’s wireless setup again with the new SSID/password. A driver reinstall alone cannot reconnect a printer whose saved router credentials are no longer valid.

Before calling it a driver problem

Prove the network layer first. If the printer itself is not connected to the router, fix Wi-Fi. If it is connected and another device can print, focus on the affected computer’s queue/software.
