Envy Photo 7855 disrupting internet connection

[taylormade2]

problem here and will getting another brand printer.  It interfers with network connection and is listed in networks around me as a secure network.  My router goes in and out when the printer is on so I just unplugged it and no interference and no internet signal loss.  I will not buy another HP 7800 ENVY Photo again

Dear Customer,

We are extremely sorry to hear that printer has interference with the network.

We found that, it is due to the  some router updates try to stop printer IPV6 requests. 

Here is the easy work around to disable IPV6 on the Printer

On Printer, It is under Advanced Settings once you click wireless or settings (pick the gear icon on the network summary screen).

and turn IPV6 off.

It will help to resolve the issue.

Thanks again.
