Claer Wireless configuration - Laserjet CP1525nw

Question

I had to replace a router in a home of a neighbor, they previously had the subject printer connected wirelessly.  The new router forced me to change the passphrase for the wireless connection from what was previously used.  The same SSID IS being used on the new router.  I have tried all attempts to reset the network settings on the printer and whenever I do and then repeat the wireless setup, be it by WPS, PIN or CD-ROM and USB cable, in ALL cases the connection fails and in best cases says security passphrase is wrong or in worst cases that the printer does NOT see the CORRECT wireless network. The oddest part, apart from the total lack of a solution on the HP forums, or even in the manuals, is that the printer keeps picking up an odd-ball SSID, "HPCP1525-135f8d", mode is ad-hoc and the IP comes up with a "bogus" number which does NOT match any local network, 169.254.123.35.  I have seen IP's like this before on PC NIC adapters which cannot connect, I believe this is some kind of internally assigned IP, not from any networking device.  That combined with the bogus SSID, I am confident the printer is the source of this BAD configuration data. I have even tried to manually set the IP, using a reserved IP on the router which I set up just for this printer.  Still nothing, it fails to connect and collects and saves this bad SSID and IP. How the h*ll do you get the NVRAM of the printer to drop this IP and FORGET that SSID? Do NOT tell me to re-run setup, I have tried multiple times, that may temporarily clear the data, but in re-running the setup it to again collects and SAVES the bad configuration data. My best guess, and another solution which cannot be found ANYWHERE, is how do you do a HARD factory reset on the printer???  I have just about had my fill of the user-friendliness of these HP interface and setup software!!!!! HELP!!!!

I found this on an earlier post and it works for the person.  You have to first connect the printer with a ethernet cable to your network router as there should be ports available and then follow the instructions below: The No-Bull**bleep** Way To Setup Your HP CP1525nw For Wireless Printing Connect the printer to your router via ethernet cable.At this point you might need to navigate via the LCD and printer buttons to the Network setup. It’s a simple menu tree that you navigate via clicking the arrow buttons and clicking OK. Just connect via Ethernet and use DHCP. It should connect itself to your network.Once the printer connects to your network it will display its IP address on the printer’s built-in LCD screen.Enter that IP address into a web browser on a computer that is on the same network. After you click enter you will be presented with a web-based administration interface for your printer.Click on the “Networking” tab.Click on “Wireless Configuration” on the left-hand options.Status should be “ON”
Configuration Method should be “Join an existing network”.
Network Name should present a list of available networks. Click on yours.
Authentication should be set according to your networkClick APPLY and disconnect the wired connection to the router. The little wireless light on the front of the printer will start blinking as it connects to your router wirelessly. Once the light is solid the printer’s new IP address should be displayed on the built-in LCD display.  You should now be able to connect using that ip address.
