OfficeJet 4650 Won't connect to Wi-fi anymore, tried many solutions...

A couple months ago I helped a friend set up a new Win10 laptop and OfficeJet 4650 wireless printer.

It worked fine upon initial intstall. Recently I went back over to set up a new router/modem they got.

The internet connection is working fine and wifi is connecting on all other devices except the HP printer.

I've tried the WPS button as well as entering the wifi password manually...several time. It spins for a while and comes back saying it can't connect and to try again. It never works.

I went into the printers deeper settings and turned of IPv6, only because the computer's network settings didn't have anything listed under IPv6. That didn't change anything as far as successfully connecting...it was just a try.

I also tried turning off the 'automatically acquire IP address' thing in the printers settings...that didn't have an effect either.

I tried to manually enter the computer's IP and subnet mask numbers in the printer but that didn't make it connect either. It wouldn't allow 198.162.1.4 to be entered, it said the numberr must be less than 255...so I did 198.162.1.1 which it allowed, but had no effect of trying to connect.

If I recall correctly, when I look at the network settings in the printer menu...the IP was blank or not available or something like that. I also tried uninstalling and re-installing the software, since it worked when it was installed the first time, but that had no effect either.

Connecting with USB still prints normal.

Any other suggestions ? This printer was purchased for the sole purpose of printing wirelessly.

Your IP is most likely wrong.

You need 192.168.1.x...

I mis-typed the IP in my original post, the numbers in your response are what I used on the printer.

That is when I had to type 192.168.1.1 even though the computer's network settings actually said the IP was 192.168.1.4

It wouldn't let me use the number 4. Also, it was also set up in this format on the printer xxx.xxx.xxx.xxx

Further down in the computer's network settings it also said 192.168.1.1 rather than 192.168.1.4 but even though it excepted that IP address, the printer still wouldn't connect to the wifi name/password.

Reset the printer back to Network Defaults.  

Now let's set a static IP correctly.  In your router:

Set the starting DHCP address to 192.168.1.100

Set the ending DHCP address to 192.168.1.150

Set the static IP in the printer to 192.168.1.10.   Now the printer is outside the DHCP window of the router.

Set router wireless to channel 1 never 'auto'.    Make sure printer is at least 5 feet from router.

Now use the Wireless Setup Wizard if you have that on the front panel to connect to your SSID with password.

Thanks, I'll try that the next time I go over to their house to fiddle with it.

Quick question, am I changing the Static IP/DHCP numbers in the computers network settings...or...by going to 192.168.1.1 in the browser's address box ? 

Also, I'm wondering why I have to do any of this at all ? It worked fine on the initial/simple set-up, at first, and obviously they aren't marketed as having such a minutiae filled installation that the "every day user"  wouldn't understand.  Further evidenced by the fact that the supplied installation papers mention nothing of these type of steps.

You are going into your router at 192.168.1.1 and changing the starting and ending DHCP addresses in the router.   Then in the printer you are going to assign a static IP outside those addresses.

Why?  Well Printer manufacturers don't want to fiddle with the router settings, and router manufacturers don't have the same default settings and don't want to fiddle with printers.  Mainly because printers are dumb.  They are the only device that can not send an interrupt to the router by itself.
