cp1525nw
Microsoft Windows 11

I have a CP1525nw printer and recently replaced my router. I can no longer connect it to Wifi. WPS fails. I have connected with an ethernet cable and manually entered the wifi info, but it still doesn't connect. There seems to be a way using software called "HP Printer Assistant", but that software is not listed on the HP support website for my printer. I can connect with USB and print. Help!

Hi @TripleFJeff,

 

Thank you for the response.

 

Here's what you can try next:

Temporarily Disable 5 GHz and Use Only 2.4 GHz

Even though your router supports both, older printers like the CP1525nw can get confused:

Go to your router settings (usually 192.168.1.1 or 192.168.0.1).

Temporarily disable 5 GHz band, or rename the 2.4 GHz and 5 GHz SSIDs differently (like: MyWiFi-2G and MyWiFi-5G) so you can target 2.4 GHz specifically.

Re-attempt setup via EWS.

 

Switch from WPA3 to WPA2 Encryption

The CP1525nw may not understand WPA3 encryption (common in new routers).

On your router’s Wi-Fi security settings, make sure it’s set to:

WPA2 (AES) or WPA2-PSK (AES)

Not WPA3 or Mixed WPA2/WPA3

 

Assign a Static IP

Sometimes DHCP bugs out:

While connected via Ethernet, log in to the printer's EWS.

Under Networking > IPv4 Configuration, set:

Manual IP (same range as your router, e.g. 192.168.1.100)

Subnet Mask: 255.255.255.0

Default Gateway: Your router IP (e.g., 192.168.1.1)

Then configure the Wireless settings.

Disconnect Ethernet and restart the printer.

 

Forget Old Access Points in the Printer

The CP1525nw might be hanging onto a previous access point config that’s now invalid.

Go to the EWS > Wireless Settings, and do a Restore Wireless Defaults again.

Then retry connection cleanly.

 

Check for Hidden MAC Filtering

Even if your router says “MAC filtering is off,” it may still be:

Whitelist only mode by default (especially true on some ISPs or mesh systems).

Just to be safe: Go to your router’s MAC filtering section and add the printer's MAC address manually as an allowed device.

MAC address is listed on the Network Config Page.

 

I hope this helps.

Hi @TripleFJeff,

 

Welcome to the HP Support Community! 

 

Thanks for reaching out about your query regarding your printer!

We're thrilled to have the opportunity to assist you and provide a solution.

 

Try these steps:

Verify Network Settings

Ensure your network settings match after the router replacement:

  1. Confirm the new router’s Wi-Fi name (SSID) and password.
  2. Make sure your router is set to broadcast the 2.4 GHz frequency, as some older printers may not support 5 GHz.

Reset Network Settings on the Printer

Clear previous network settings on your printer:

  1. Press the Setup button on the printer’s control panel.
  2. Navigate to Network Setup > Restore Defaults.
  3. Confirm the reset. This will delete any old network settings.

Connect via Ethernet to Configure Wi-Fi

Since you're able to connect via Ethernet, use it to configure Wi-Fi:

  1. Connect your printer to your router with an Ethernet cable.
  2. Print a Network Configuration Page:
    • Press the Setup button.
    • Navigate to Reports > Network Configuration Page.
  3. Open your web browser and enter the IP address listed on the Network Configuration Page to access the printer’s embedded web server (EWS).

Configure Wi-Fi Through the Embedded Web Server (EWS)

Use the printer’s EWS to configure Wi-Fi settings:

  1. Open the EWS and navigate to the Networking tab.
  2. Select Wireless Setup Wizard.
  3. Follow the on-screen instructions to connect to your new Wi-Fi network.

Use HP Printer Assistant

If you were previously using HP Printer Assistant but can’t find it for your printer model, try the following:

  1. Download and install the latest drivers and software for the CP1525nw from the HP Support Page.
  2. During the installation, choose Wireless connection and follow the prompts to set up your printer on the new network.

Print Wireless Network Test Page

Check the status of the Wi-Fi connection:

  1. Press the Setup button.
  2. Navigate to Reports > Wireless Network Test.
  3. Print the report and review any issues highlighted.

Update Printer Firmware

Kindly refer to this link to update your printer firmware.

 

I hope this helps.

I have done these steps except for the firmware, but the firmware hasn't changed since 2014

I can connect through ethernet, then using the EWS it allows me to pick the SSID from a list and enter the password. When it's done, it says that I need to disconnect the ethernet in order to enable the wireless. When I do that, it doesn't connect.

I printed the test report and it says that "No FIltering" = Fail and "MAC address filtering may be enabled", but I checked and it is not.

I should note that the router I replaced was really just an access point for another router that didn't change. I tried to connect directly to the wireless on that router and I get the same thing.

The issue was the WPA2/3. The only way to disable the WPA3 was to turn off the 6GHz. If 6GHz is on it has to be set to WPA2/WPA3 since 6Ghz is WPA3 only and there is no way to set it individually for each band. To set it up initially I had 5GHz off, but now with 5GHz on it still connects.
