Connecting your HP Deskjet 4155e to WiFi is usually straightforward, but it depends on your network setup and how you want to configure the printer. This guide covers the three practical ways to get it online, then walks you through verification and troubleshooting when things don’t work on the first try.
If you only remember one thing: use the HP Smart app when possible, and make sure your phone/computer is on the same WiFi network you want the printer to join. The printer typically needs a 2.4 GHz connection for reliable setup.

- WiFi network name (SSID) and WiFi password
- A phone or computer on the same WiFi network (recommended for HP Smart setup)
- Your router nearby (especially if you’ll use WPS)
- The printer powered on and ready (paper loaded is fine, but not required for setup)
2.4 GHz matters: Many HP Deskjet setups work best when the printer connects to a 2.4 GHz SSID. If your router uses a combined name for both bands (like MyWiFi for 2.4 + 5 GHz), consider temporarily using the router’s separate 2.4 GHz name (like MyWiFi_2G), if available.

Confirm Your Printer Model and Current WiFi State
Make sure you’re working with an HP Deskjet 4155e. On the printer itself, look for the Wi-Fi light or a Wireless button. Before attempting setup, confirm the printer isn’t already connected to a different network.
If the printer has a Wi-Fi icon that’s blinking, that usually indicates it’s searching or not fully connected yet. If it’s solid, it may already be online—verify it in HP Smart.
Method 1: Connect Using the HP Smart App (Most Reliable)
The HP Smart app is the most dependable option because it guides the connection flow and pairs the printer to your network. It also reduces the chance of entering the wrong SSID/password.
Free tools Windows power users keep installed
One-click scans. No signup required.
On Windows 10/11
- Install HP Smart from the Microsoft Store or hp.com.
- Connect your Windows PC to the WiFi network you want the printer to use.
- Turn on the HP Deskjet 4155e.
- Open HP Smart.
- Click + (Add printer).
- Select your printer (it may appear as “HP Deskjet 4155e” or similar).
- Choose Continue when prompted, then follow the on-screen steps to connect to WiFi.
- When asked for WiFi, pick your SSID and enter the password exactly.
If prompted about WiFi bands, prefer a 2.4 GHz SSID. After setup finishes, HP Smart should show your printer status as Connected or Ready.
On macOS (Intel or Apple silicon)
- Install HP Smart on your Mac (available via hp.com or the Mac app route supported by HP).
- Connect your Mac to the correct WiFi (again, ideally 2.4 GHz).
- Open HP Smart and click Add Printer (or +).
- Select the HP Deskjet 4155e when it appears.
- Choose the option to set up a new printer and follow the WiFi prompts.
- Select your SSID and enter the password.
Mac setup often succeeds faster when the printer and Mac are on the same router band (2.4 GHz is the safest bet).
On iPhone / iPad (iOS)
- Install HP Smart from the App Store.
- Connect your iPhone/iPad to the WiFi network you want the printer to join.
- Open HP Smart.
- Tap + Add and select your printer when it shows up.
- Proceed through the setup flow and choose Wireless Setup (wording varies slightly).
- Select the WiFi network and enter the WiFi password.
If iOS asks for permission to find/configure local devices, allow it. Without local network permission, HP Smart can fail to complete discovery.
On Android
- Install HP Smart from Google Play.
- Connect your Android device to the WiFi network (prefer 2.4 GHz).
- Open HP Smart.
- Tap + Add.
- Choose your printer (HP Deskjet 4155e) when detected.
- Follow the prompts to connect to WiFi, then enter SSID and password.
Some Android phones restrict local network access. If discovery fails, check that HP Smart has location/local network permissions enabled in system settings.

Method 2: Connect Using WPS (If Your Router Supports It)
If your router has a physical WPS button, this can be quick. You’ll usually need to press WPS on the router and start WPS pairing on the printer within a short time window.
WPS setup steps
- On the router, find the WPS button (often labeled “WPS”).
- Press and hold the WPS button for 1–3 seconds to start pairing.
- On the HP Deskjet 4155e, press the printer’s Wireless or Wi-Fi button (or choose WPS option in the WiFi menu if shown).
- Wait up to 2 minutes for the WiFi light to stop blinking.
- Verify connection in HP Smart by adding the printer again, if needed.
Gotcha: WPS isn’t always enabled on guest networks or some ISP router models. If WPS keeps failing, switch to HP Smart setup.
Method 3: Connect From the Printer Control Panel
You can manually connect without HP Smart, but it requires careful SSID/password entry. The menu labels vary slightly depending on firmware, but the flow is consistent: WiFi menu → network selection → password entry → connect.
Where to find WiFi settings on the 4155e
- On the printer, open the Setup or Wireless menu.
- Select Wireless Setup Wizard (or similar).
- Choose your WiFi network name (SSID) from the list.
- Enter the WiFi password.
- Confirm Done / OK / Connect.
- Wait for the WiFi light to become solid.
If your SSID is not showing, move closer to the router and confirm the network broadcasts (some “hidden SSID” setups won’t appear in the list).
Use a 2.4 GHz WiFi Network (Common Requirement for Setup)
If your router uses separate bands, connect the printer to the 2.4 GHz SSID. If your router combines bands under one name, consider temporarily splitting them so you can choose the 2.4 GHz network during setup.

| Router Setup | What to do | Why it matters |
|---|---|---|
| Separate 2.4 GHz and 5 GHz names | Select the 2.4 GHz SSID in HP Smart/control panel | Improves discovery and reduces setup retries |
| Single combined SSID | Use the router’s “Smart Connect” off or choose 2.4-only name if available | Printers may fail if they end up on 5 GHz |
After Connection: Print a Test Page and Verify the IP
Once WiFi is connected, confirm it with an actual print. In HP Smart, choose your printer and select Print or Print a Test Page (wording varies).
If you prefer checking network details, you can view printer network info in HP Smart or the printer’s network status menu. Look for fields like Wi-Fi status, IP address, and Network name.

Setup problems usually come down to network band mismatch, permissions, or the printer not actually joining the intended SSID. Work through the fixes in order for the fastest resolution.
Printer won’t show up in HP Smart
- Restart the printer and your router (power off, wait 20 seconds, power back on).
- Make sure your phone/PC is on the same WiFi network (not mobile hotspot, not a different SSID).
- Disable VPN temporarily on your computer/phone.
- Check local network permissions for HP Smart on iOS/Android.
Wrong WiFi credentials / endless retry loop
- Re-enter the password from the control panel using the printer’s character keyboard (copy/paste isn’t available).
- Verify you aren’t using an auto-correct or hidden character in the password.
- Try a manual WiFi reset on the printer (WiFi menu → Restore/Reset Network Settings, if available), then set up again.
Connected to the wrong network (2.4 vs 5 GHz)
- Confirm the connected SSID in the printer’s WiFi status screen.
- If the printer is on the wrong band, re-run the WiFi setup and choose the 2.4 GHz SSID.
- If your router uses band steering, temporarily separate networks or turn Smart Connect off.
Restart sequence that usually fixes it
- Turn off the HP Deskjet 4155e.
- Power off your router.
- Wait 60 seconds.
- Turn the router back on and wait until WiFi is stable (usually 2–5 minutes).
- Turn the printer on and wait for the WiFi light to settle.
- Run HP Smart setup again.
Update firmware and drivers
Some connection issues are firmware-related. Update the printer software/firmware using HP Smart on your computer or check HP’s support page for the latest firmware and driver for the Deskjet 4155e.
After updating, reconnect to WiFi (don’t assume the update automatically keeps the old network settings).
Comparison: HP Smart vs WPS vs Manual Entry
| Method | Best when | Main downside |
|---|---|---|
| HP Smart app | You want guided setup and fewer credential mistakes | Requires phone/PC permissions and local network access |
| WPS | Your router supports WPS and the printer is near the router | Often fails on certain router/ISP setups or guest networks |
| Manual entry | You can’t use an app or need to set exact SSID/password | More typing errors, especially for long passwords |
FAQs
Why won’t my HP Deskjet 4155e connect to WiFi?
Most failures happen when the printer is trying to join the wrong band (5 GHz vs 2.4 GHz), the WiFi password is mistyped, or the device running HP Smart is on a different SSID/VPN. Confirm SSID/band and retry using HP Smart.
Do I need to connect the printer to 2.4 GHz WiFi?
For reliable initial setup, yes—2.4 GHz is the safest choice. If you only have one combined SSID, use your router settings to ensure the printer can connect to the 2.4 GHz portion.
Crashes, No Sound, or Screen Glitches?
Random freezes, missing sound and display glitches usually trace back to one bad driver. Find and replace yours safely.Free scan · under a minuteWindows Errors? Fix Them Before They Spread

Open HP Smart and confirm the printer status shows Connected or Ready. You can also check the WiFi status/IP details in the printer’s network menu.
Can I connect the HP Deskjet 4155e to WiFi without a computer?
Yes. Use the HP Smart mobile app or the printer’s own WiFi setup wizard/menu to connect directly from the printer.
Will connecting to WiFi replace USB printing?
No. WiFi adds a network path. If you ever need to print via cable, you can still do it, but you’ll generally want to use one method consistently to avoid driver confusion.
Bottom Line
If you want the highest success rate, connect your HP Deskjet 4155e to WiFi with the HP Smart app and ensure both your device and printer are using the same 2.4 GHz network. Most “it won’t connect” cases resolve after correcting SSID/band and re-running setup.
When things get stuck, use the restart sequence, verify the printer’s connected SSID in network status, and avoid VPN/local network blocks that prevent discovery. Once it’s online, HP Smart makes test printing and printer management simple.
