Swapped routers, printers offline

Switched routers (Netgear Nighthawk) and am having printer problems.  Printers are hardwired and basically nothing changed except the router; all network connections are the same.

Software: Windows 11 (26200.9728); all drivers up-to-date

Hardware:

      ASUS Vivobook 14 Flip

      Canon ImageCLASS MF465dw laser printer

      Epson Ink Jet

Fiber > Router > downstairs 5 place switch > Wire in wall > Upstairs switch > Printers

Reset Canon printer.

I have these ports active on my computer.  Tried to delete the TCP/IP ports and they would not delete (in use).

I thot deleting them might let me start over.

 Spent 3 hours on-line with COPILOT without success, troubleshooting.  After all Copilot troubleshooting, both printers IP are set to 0.0.0.0.  Copilot generated this:

Summary of the problem: The printer’s IPv4 address remains 0.0.0.0 under all conditions. It never obtains an IP address from DHCP.

Troubleshooting already completed:

·        Set IPv4 to Auto Acquire / DHCP = SET

·        Performed Initialize Network Settings

·        Power‑cycled the printer after reset

·        Verified the Ethernet cable and router LAN port using other devices (they obtain DHCP normally)

·        Connected the printer directly to the router’s LAN port with a known‑good cable

·        Bypassed all switches, patch panels, and intermediate wiring

·        Rebooted router and printer multiple times

·        Confirmed link lights are active on both the router and printer

·        Confirmed no MAC filtering or isolation on the router

·        Verified the printer is not set to manual IP mode

Result: Even when connected directly to the router, the printer still shows:

·        IP Address: 0.0.0.0

·        Subnet Mask: 0.0.0.0

·        Gateway: 0.0.0.0

Tried to contact Canon.  Impossible.

Anyone have any suggestions that might help me get my printers back on line?
