hp laserjet 400 mfp m425 pcl 6 how to connect to internet

I can print when it is connected with a USB cable, scanning to a USB key, so printing/scanning equipment works. I can ping the printer to the router, then the wireless hardware works. Now the printer will not connect to the router. I serve my 8600 OfficeJet Pro on a local network with a wireless connection to a router.

Update: installing drivers PS does not solve it either. P3015s most are a few years old but is new and still under warranty. For the moment, we have this problem in 4 separate hotels. I would like to know if it is a common mistake that has resurfaced recently. The installed driver is universal PCL6 because there is no specific driver for this printer. After awhile, an error is displayed for the printer in 'devices and printers'. There is no error in the printer event log. When a test page is sent, no data seems to go to the printer. The printer is connected and accessed via a web browser. The problem when the drivers are installed directly on the computer of the user (Windows 7 Pro). This is shared through Windows 2008 R2 servers network printers. We provide that HE supports for a number of hotels, and for about a month, we had problems with a number of printers P3015 different properties not being not able to print.
