Printer not compatible with 5Ghz WiFi SUDDENLY

[MargB]

HP Officejet Pro 9130e all in one.  Printer suddenly quit working after just 5 months.  When I called customer support, HP says my printer doesn't support 5 Ghz and that is why it quit working, but I've been using it on another HP computer and then my new HP computer (both desktop) since September 2024.  They told me to call my internet provider and have them split it to 2.4 Ghz.  I did this and Sprectrum came out the same day.  He told me the printer DOES support 5G and said the HP support person just didn't want to acknowledge that the WiFi antenna had a sensor problem.  I might not be saying this correctly.  But when I originally called Hp I had a solid blue WiFi light.  After he completely removed the printer from everything, I had a blinking blue WiFi light.  Spectrum connected printer using a ethernet cable so that I would be able to print.  Now I have no blue light at all.  I think HP should repair or replace printer so I can use the WiFi option.  And where do I find the information about wifi compatibility?   Has anyone else had this problem?

@MargB, Welcome to the HP Support Community! 

Thanks for reaching out about your query regarding your printer not being compatible with 5Ghz Wi-Fi!  
We're thrilled to have the opportunity to assist you and provide a solution.

It sounds like you're dealing with a frustrating issue with your HP OfficeJet Pro 9135e printer, particularly regarding the WiFi connectivity. Let's break it down:

WiFi Compatibility: According to the HP OfficeJet Pro 9135e specifications, this model should support both 2.4 GHz and 5 GHz WiFi bands. If the printer was previously working on both your old and new HP desktop computers, the issue might not be with the WiFi compatibility itself but with the printer's WiFi module or settings.

Blinking Blue WiFi Light: The blinking blue light typically indicates that the printer is in WiFi setup mode, meaning it’s not connected to any network. This could be due to a problem with the WiFi antenna, a misconfigured network setting, or a hardware malfunction.

Possible Causes and Steps:

• Reset the Printer: Perform a hard reset on the printer by powering it off and then on again. Sometimes, this can resolve issues with the WiFi connection.
• Reconfigure WiFi Settings: Try setting up the printer’s WiFi connection again. You can do this by navigating to the printer's control panel > Network settings > Wireless Setup Wizard, and connecting it to your WiFi network.
• Check for Firmware Updates: Ensure that the printer's firmware is up-to-date, as an outdated version can sometimes cause connectivity issues. You can check for updates through the printer’s settings or via the HP website.

Ethernet Cable Connection: It’s great that Spectrum connected your printer with an Ethernet cable, as this temporarily fixes the printing issue. However, this doesn't resolve the underlying WiFi issue.

Additionally, you can verify this in the printer's settings or check the network configuration page if you’re able to access it.

Let me know if you need further assistance.

Take care and have an amazing day!
