HP DeskJet 2855e Won’t Connect to WiFi, Step by Step Fix

Your HP DeskJet 2855e refuses to connect to WiFi, and now nothing prints. You may see the printer offline message, flashing blue light, stuck print jobs, or error messages saying the printer is not responding. Sometimes it prints a test page with a USB cable but fails over wireless.

This is frustrating, especially when you need to print something quickly.

In many cases, the real cause is outdated or corrupted printer software on your Windows computer. A recent Windows update can interrupt how your printer communicates with your network. The good news, this is usually easy to fix. Follow the simple steps below to reconnect your HP DeskJet 2855e and get back to printing.

Quick Fix Checklist

Before diving into advanced steps, try this quick checklist:

• Restart your printer and WiFi router
• Restart your Windows 10 or Windows 11 computer
• Make sure your printer is within range of your router
• Confirm your computer is connected to the same WiFi network
• Clear any stuck print jobs in the queue

If your HP DeskJet 2855e still will not connect to WiFi, continue below.

Why Your HP DeskJet 2855e Won’t Connect to WiFi

Your printer depends on software installed on your Windows computer. This software allows your PC to talk to the printer over your wireless network.

If the software is outdated, missing, or damaged, your printer cannot properly communicate with Windows. This leads to:

• Printer showing offline
• WiFi setup failing
• Printer not responding
• Slow printing
• Blank pages
• Color printing problems

Windows 10 and Windows 11 updates can sometimes replace or disable printer files. Even small system updates can interrupt the wireless configuration. That is why this issue often appears suddenly.

Method 1 – Fastest Fix Using DriverAssist (Recommended)

The quickest way to restore your WiFi connection is by using DriverAssist. It automatically finds the correct software for your HP DeskJet 2855e and installs it properly.

This saves time and avoids downloading the wrong version.

Follow these steps:

1. Download and install DriverAssist
2. Open the program and start the scan
3. Let it detect outdated or missing printer software
4. Click update and allow it to complete
5. Restart your computer

After restarting, reconnect your HP DeskJet 2855e to WiFi using the printer setup option in Windows Settings.

Why this works:

DriverAssist detects compatibility issues between your printer and your Windows version. It ensures the correct files are installed, which restores wireless communication and fixes printer offline errors.

Method 2 – Download Software from HP Website

If you prefer to install manually, you can download the correct software from the official HP support website.

Step by step:

1. Open your browser
2. Go to the official HP support page
3. Type HP DeskJet 2855e in the search box
4. Select your exact printer model
5. Choose your Windows version, either Windows 10 or Windows 11
6. Download the full feature software package
7. Run the installer and follow on screen instructions
8. Restart your computer after installation

Important tips:

• Make sure you select the correct Windows version, 32 bit or 64 bit
• Do not download software for a similar HP DeskJet model
• Avoid third party download sites

After installation, use the HP Smart app or Windows printer setup to reconnect the printer to your WiFi network.

Method 3 – Update Through Windows Device Manager

You can also attempt to update the printer through Device Manager. This method is built into Windows, but it may not always find the latest version.

Steps:

1. Right click the Start button
2. Select Device Manager
3. Expand Printers or Print queues
4. Right click HP DeskJet 2855e
5. Choose Update driver
6. Select Search automatically for updated software

If Windows finds an update, install it and restart your computer.

Limitations of this method:

• Windows may say the best software is already installed
• It may not detect corrupted files
• It does not always install full feature software

If this method fails, use Method 1 or Method 2.

Reconnect HP DeskJet 2855e to WiFi After Updating

Once software is updated:

1. Turn on the printer
2. Press and hold the Cancel button and Wireless button together for five seconds to reset network settings
3. Open HP Smart on your PC
4. Select Add Printer
5. Choose your WiFi network
6. Enter your WiFi password

Wait for the blue light to turn solid. This means the printer is connected.

Why This Problem Keeps Coming Back

Many users fix the issue once, but it returns after a Windows update.

This happens because:

• Windows updates can overwrite printer files
• Network settings may reset
• Security patches may block older printer software
• Corrupted installation files remain on the system

If your HP DeskJet 2855e keeps going offline or disconnecting from WiFi, the software may not be fully compatible with your current Windows build.

Keeping your printer software updated prevents recurring connection problems.

How to Keep Printer Software Updated Automatically

Instead of manually checking for updates every few months, you can use a tool that monitors your printer software.

Automatic update tools:

• Detect missing files
• Install compatible versions
• Reduce wireless communication errors
• Prevent printer not responding issues

This is especially helpful for Windows 11 users, where frequent system updates can interrupt printer connections.

Windows 10 vs Windows 11 WiFi Issues

Windows 10 users often experience printer offline errors after feature updates.

Windows 11 users sometimes see devices disappear from the printer list entirely.

The fix steps are the same, but Windows 11 may require re adding the printer under:

Settings > Bluetooth and devices > Printers and scanners

After updating the software, always restart your system.
