WiFI keeps disconnecting from Envy 6400

[JACKIETOOLS]

Can I connect this printer direct to my Verizon router then use it wirelessly from other PC's and devices. It keeps dropping connection and I have to unplug it each time to get it back on line. Just bought it. Very frustrating. Thanks

My Verizon network has SON enabled. Self-Organizing Networks (SON Is this messing up the connection? Thanks

[JACKIETOOLS]

Also I have numerous printers connected to my PC. I do not want the HP as my default printer. Don't think that should matter. Set it up thru HP Smart App and have 4 home PC using the app to use it The WIFI indicator is always a steady blue but I must unplug the printer and then plug it back in it reconnects. I tried changing wifi to 2.4 instead of 2.4 and 5 but it came offline again. Set it back to both frquencies. About an hour ago I printed out printer info page and shows IP address as [personal info removed]. I just set it manually to that address about an hour ago. When I look at IP address in HP Smart the IP address says [personal info removed] which does not match the [Personal info removed] that printout page says.

@JACKIETOOLS 

For those reading:  Network Information indicates the printer is connected to IPv6.

Printer does not show itself to be connected to IPv4 address.

I am not familiar with SON configuration.

@greenturtle 

Do you have any words of wisdom?

Thanks in Advance.

Just checked and its off line again. I don't understand why it comes coming off line. Any other suggestions

[JACKIETOOLS]

Just unplugged and plugged back in and its back online. Is the printer defective? I thought it was supposed to have more reliable WiFi. This may end being a return if this can't be solved. Thanks for your help

[JACKIETOOLS]

I see it says configured by DHCPv6. Is this normal?

[Dragon-Fur]

@JACKIETOOLS 

Not staying connected to IPv4 is not normal.

Defaulting / Only connecting to IPv6 is not normal.

That said, there is a lot of room for my having missed something.

I am not familiar with this printer series.

Defective? - I don't know.  Could be.  Unusual, though certainly possible.

Related to your network setup?  Maybe. I don't know.  If the SON network rotates connection points, it may be causing the results. 

Hopefully our HP colleague @greenturtle (other side of the planet - forgive delays) will see my request and be able to help.

Nice printer - but useless if it won't work with your network or if it is defective.

If you don't have time to wait, I can well understand your returning the printer.
