Laserjet Pro M102W blue wireless light off after firmware update

[tan3086]

I installed the 20200605 firmware via USB, now wireless light blinks at poweron then remains off and will not connect wirelessly.  USB connection shows that wireless stetup info is still correct, but light remains off after USB removed and powered down and up again.

@tan3086, Welcome to the HP Support Community!

Press the wireless button to turn the feature on/off.

If your router supports WPS, use these steps to connect your printer to your wireless network with the WPS button on the router.

1. Turn on the printer.

2. Locate the WPS button on your router, but do not press it yet.

   If your router does not support WPS, skip to the next step to connect the printer with the HP Smart app.

3. On the back of the printer, press and hold the Wireless button  and Power button  at the same time for 3 seconds.

4. On the router, press and hold the WPS button for 3 to 5 seconds or until it shows that the WPS connection process has started.

   NOTE: The printer stops searching for a WPS connection two minutes after the wireless button is pressed. If you were unable to press the WPS button within that time frame, attempt these steps again.

   Once the printer connects to the wireless network, the purple Wireless light on the control panel turns on solid.
