Product: LaserJet Pro 400 Color M451dn
Operating System: Microsoft Windows 10 (64-bit)

HP basic printer drivers can't find my wired LaserJet Pro 400 Color M451dn. It's got it's correct IP address, shows up on my DD-WRT router (TP-Link TL-841N) as active, and DHCP client (has static DHCP reservation). LaserJet's Airprint is working OK, even downloaded & installed online firmware through printer menu & LAN no problem. Computer is online fine, as is printer; they just can't see each other when installing drivers.

Used auto-search, IP address, MAC address, host name: no dice.
Uninstalled drivers & updated firmware, then tried drivers install again: no dice.
Shut off every device: cable modem, router, switch, computer, printer: no dice.

Changed ethernet port from switch to router: no dice.

Wiggled all ethernet cables: no dice.

Installed print & scan doctor: no dice.

Running Norton Internet Security, disabled firewall: no dice.


All OS software updated & current.

(Couldn't give up. Daughter had homework to do on the printer.)

First, I went to Devices and Printers in Windows 10 and chose "add a printer." It was not cooperating, but I gave it the IP address and said "have disk" and directed it to the HP install files (they plop on your root drive when it unpacks at install startup, they were still there). It finally installed the printer, but with all the bloatware I didn't want. So at least I knew it was possible. I uninstalled that added device entry and went back to searching...

This time I searched on DD-WRT for a similar problem and found this online at:

https://www.tenforums.com/network-sharing/72242-lan-connected-not-shared-printer-does-not-see-window...

"Solution found!
The problem was with the router (firmware?). After completing the following the issue is resolved:
1) log in to your router IP. "192.168.1.---"
2) on DD-WRT GUI, select ADMINISTRATION
3) select COMMANDS
4) in commands box enter the following code (make sure there are no spaces at the end):
swconfig dev eth0 set enable_vlan 1
swconfig dev eth0 set apply

5) below the box click RUN COMMAND
6) If this runs without error, then lastly click SAVE TO STARTUP."

I followed the steps and the printer was easily found by the HP install software, auto find, first try. Whew! Now to find out what I did...I'd much rather make the changes to the configuration manually than rely on a set of startup commands every time...

Anybody know DD-WRT well enough to say how these changes can be made manually?

TIA!
