HP Deskjet Ink Advantage 4645 cannot connect to wifi

[Lih_j]

Hi, my HP Deskjet Ink Advantage 4645 couldn't find my wifi. I had touched the  "Restore Network Defaults". And when I touched "Wireless Setup Wizard" to search for network/ wifi, the searching keeps going and my printer froze. Hence, I had to unplug and try the whole process again. Nonetheless, it experienced the same things over and over again. Therefore, I couldn't connect my printer to wifi at all.

I also tried to download driver and connect my printer to a laptop using USB-cable so that i can complete printing jobs. However, it couldn't be set up as my laptop couldn't detect my printer at all. Hope anyone can help me.
