Losing network connectivity on 400 MFP M425dn

After I set up the printer with the network settings, everything works fine for the first 5 minutes or so. Then, I lose connectivity. This happens whether it is a static IP address or DHCP. I have also updated the firmware to the latest revision. This is happening on both printers we have that are the same model (brand new). Does anyone have any idea why this is happening? Thanks ...

Re: Losing network connectivity on 400 MFP M425dn

Hi gbotko,

try this,

under Networking Tub ->IPv4 Configuration
change from DHCP on Manual, put your ip address and save
Now you can connect to printer with new ip(manual)
now, under Networking Tub go
Advanced options(on right side) and uncheck DHCP options and save
if you have DNS and WNS , you can setup it on Networking tub ->Network Indetification.

Hope it help you

Re: Losing network connectivity on 400 MFP M425dn

Thanks for your help. I did as you instructed but I get the same results. I can ping the printer or get to it through Internet Explorer using it's IP address for a few minutes then I cannot get to it. If I run a continous ping, I get a reply for about 2 - 3 minutes, the I get Request timed out.

I called the HP support line last week and they told me that port 25 was being blocked. Isn't that used for email?

Both items were unchecked

It was enabled. I disabled it.

 

I ran a continous ping and after 2 - 3 minutes, the request times out.

 

Thanks ...

Hi gbotko,

if it router, maybe you need check options on router

It is on our LAN at the hospital. The cable that is plugged in to this new printer is normally plugged into an HP LJ 4200 that we use in this office. We have never had problems in the past with network connectivity from this network jack.

Re: Losing network connectivity on 400 MFP M425dn

Was this ever resolved?

Our company recently purchased many of these models, tons of LAN issues.

HP tier 1 assumes it's our device. Our other networking devices work fine, it's only with the HP MFP425dn.

We're reaching out to our HP reps to see what they can do for now.

I don't mean to dig up ancient threads, but I forgot to reply back and say the issue was resolved on our side. We had to disable PoE at the switch port on our Cisco 2811 routers I believe. May not apply to OP's issue but it helped resolve ours! Thanks.
