Summary: It's weird~!I cannot link this printer through wifi to my new dell inspiron 5520. I tried other laptops. It seems that the wireless driver "Intel(R) Centrino(R) Wireless-N 2230" doesn't fit the printer's driver because when I used a USB wireless network adapter to plug in the inspiron 5520, the printer worked! I don't know how to figure out that. So now I just use the USB connector to link the printer to my laptop.
