MFP does not allow to print through wi-fi connection. wi-fi button is blinking. I tried to solve it with site instruction and finally I switched off wi-fi direct setup that became disabled. now I can not even go to printer ews page.

Hi,

Print and evaluate a Wireless Netowrk Test Report as explained below:

https://support.hp.com/us-en/document/c05874648

Within the Configuration Summary section, can you see the Network Name (SSID) lists your network name or any other value?

Assuming your network name is listed correctly, what information is listed within the Troubleshooting section? otherwise please clarify what exact information is listed for the Network Name, to better understand what are the next steps to try.

Hello,

I followed your instruction, but I failed to solve the problem. 

Troubleshooting says:

Your hp printer cannot find your network. a network name (ssid) was found that closely matches your wireless nerwork's name except for conflicting upper and lower case. run the printer's wireless network setup, and be sure to enter the ssid exactly, including upper and lower case. 

You hp printer cannot find wireless router. check that your wireless router is powered on. check that the printer's network name (ssid) matches the network name (ssid) if your wireless router. if the name don't match exactly, run the wireless network setup to configure your hp printer. 

the problem is: I can't run the wireless network setup. HP smart doesn't see the printer. 

how can I solve this problem?

Please make sure there is no USB cable connected to the printer.

If the power light blinks, wake up the printer by pressing the cancel button and ensure the power light is solid.

Press and hold the wireless button for approx. 20 seconds, only when the Attention light ( ! ) starts blinking release the button.

Now review your nearby wireless networks list, ensure you are connected to your home network and that you see another network starting with HP-Setup.

Open HP Smart and click the Plus sign, then click on Add Printer and follow the steps on screen to select your home wifi.
