MFP M28w no wireless connection

[hein14]

Yesterday I described my problem: My MFP28w laser jet printer suddenly does not have a WiFi connection anymore. The Wifi button is blinking blue. The printer works well with my Mac via an USB cable, but not with my MacBook Pro via WiFi. The rooter appears to be working well (Wifi download speed around 85 Mbps). I did the usual: pulling the plug on the printer and the rooter, restarting the MacBook, all to no avail.  I tried to reset the printer by pushing the ON/OFF button for 20 sec, without result.

Today I managed with the hp smart app to to do the first two steps for WiFi connection, that is the app managed to find the printer and to configurate it. However it could not  connect the printer to the WiFi network. The only advice I got is to move the printer closer to the router, but it is already only 1 m away. Now I am stuck.

I gather that there should be other means to reset the printer (other than pushing th ON/OFF button) but I cannot find them.

I am pretty frustrated about the lack of support I get from hp. I can also not find on hp websites any phone number for customer support in Belgium (apart from an unhelpful chat with a virtual assistant). My two year guarantee for the printer has just expired - if in the end I have to buy a new one I will think twice before coming back to hp!

@hein14, Welcome to the HP Support Community! I’m here to help.

I understand you are not able to connect the printer to the wireless network. Check these parameters:

1.) Remove All Barriers: Certain building materials can get in the way of weaker signals like Bluetooth. Metal, bulletproof glass, concrete, and plaster are particularly bad, and marble, plaster and brick aren’t great easy. So if you’re really struggling with interference, your first step should be to move your Bluetooth devices away from these materials. That means no brick walls between you and your devices, and definitely no metal desks! 

2.) Change Router Channel: If you have an Apple router and you’re constantly getting interference with your WiFi, try rebooting it. Upon restart, the station will search for a new channel. Specifically, a different channel than the one your Bluetooth devices is using to communicate. If you don’t have an Apple router, you may need to instead go into your router settings and try changing the channel manually. Experiment with different channels to see which one works best. 

3.) Move Closer to Your Router: If you often find that you’re getting interference when talking on a wireless headset while on a WiFi call (you’ll know because you’ll hear static), try moving closer to your router. This will give you a more robust WiFi connection, so the Bluetooth frequency can’t overpower it. 

  

4.) Get Away From Microwaves and Fluorescent Lighting: Both emit frequencies of 2.4GHz, and moving away from them will distance you from the source. 

Let us try these steps:

• Restart the router, the printer, and the Mac
• Make sure the printer and the Mac are connected to the same wireless network. Either 2.4 or 5GHz network.
• If you have a Dual-band router and both 2.4GHz and 5GHz networks share the same name/SSID, the printer will not be able to connect to the network. In this case, contact your Internet service provider to assign different names to both networks.
• Also, check with your Internet service provider if your router is able to forward 'Bonjour packets'.

Bonjour locates devices such as printers, other computers, and the services that those devices offer on a local network using multicast Domain Name System (mDNS) service records. The software comes built-in with Apple's macOS and iOS operating systems.

• This printer supports WPA encryption, check if the router is on the same encryption method. If using WEP or WPA-PSK+FT change it to WPA-PSK

Use the WPS method to connect, refer to - Connecting an HP Printer Using Wi-Fi Protected Setup (WPS)

Once connected, the blue light will become steady.

Perform a ping test to check the connectivity

1. Obtain the IP address of the printer by clicking on the Wireless icon on the printer
2. Open a new Terminal window (it's located in Applications > Utilities, or you can just start typing it in Spotlight).
3. Enter “ping” followed by the IP address of the printer. 
4. Press Return. Press ctrl C after 10 pings
5. There should be 0% packet loss, share the results in your next post.

Hope this helps! Keep me posted.
