The printer is connecting through the USB cable and is working fine, when  i folow the oin screen instructions to  convert the usb printer to Network. 

following is happening. 

wireless setiings are retreaved from py PC, 

then after i press next after selecting. " Do you want to connect and store these settings on your printer.

i am getting the following message" your printer failed to join the wireless network.  

"Issue: The network name (SSID) you entered manually could not be found.
Solution: Check that your wireless router is powered on. When manually entering your network name (SSID), make sure you enter it exactly including upper and lower case letters and any spaces.:

all the settings are good, previously the same printer has worked on the same wireless network. 

Also when i press the wireless and cancil buttons together for 3 secounds, on  the printer, nothing is happning, - it says in the user manual that the "powerlighjt will blink for a few secounds, then the printer will be in setup mode(wireless light will continue to blink until the printer is connected) 

but none of the above is happening.
