I had unpacked, set up the printer, loaded the paper, etc and got to the part about setting up the wifi connection. That's where everything went wrong!!! The instructions and printer wanted me to set up through my mobile device. It wouldn't work because the printer can only use 2.4G settings and my iphone is set to 5G. It didn't help to set the phone to 2.4G. Then I tried setting up through the provided computer disk. That didn't work either. I was ready to take the printer back to the store where i purchased it. I waited 2 days and tried again. I researched HP's website and found a statement that changed everything. It said to do the following: On the printer touchscreen, under Setup, Network Setup, select Restore Network Settings. After this is done, under Settings, go to Wireless, selct Wireless Setup Wizard. Type in your routers name and password. IT WORKED!!!!!! After that, I downloaded the set up instructions from the CD to my computer and went through the steps. IT WORKED! Follow these instructions if you are frustrated with trying to set up your wifi. I hope this helps others!
