B205: Floods of DHCP queries

[sciurius]

This does, indeed, seem to solve the DHCP floods.

I was under the assumption that everything settable from the front panel could also be set from the CWIS.

Hi, Friend !

We`re comrades in misfortune.

We`re also have the same problem. 

But by chance we found that problem is being solved when wi-fi is turned off.

P.S Question to Xerox support. Why?!

Turn off Wi-Fi on the MFP
Press "i"
Down arrow select "Network" and press "ok"
Down arrow select "WiFi on / off" and press 2 times "ok"
Down arrow to select "Off." and press "ok"
Exit the settings menu
And you will be happy))

Thanks for your reply.

TCP/IP, in particular DHCP, is configured and functioning.

Network Setup

TCP/IP Settings
TCP/IP Enabled:	Enabled
Host Name:	b205
IP Address:	192.168.1.81
Subnet Mask:	255.255.255.0
Default Gateway:	192.168.1.1
Automatic Addressing:	DHCP/Auto IP

The problem is that, after the DHCP handshake:

the printer gets its lease and should refresh after 6 hours (the DHCP lease time). However, it reissues DHCP requests every two seconds.

Hi sciurius, 

Thank you for using the Support Forum. The only thing I could find is this article in the online support for your product Fault Code 17-800: DHCP Problem Auto IP Run Message. Solution 2 in this article might help you.  If not please consider contacting your support centre for further assistance.

Xerox B205 with firmware V3.50.01.60_20200715 connected via ethernet cable.

TCP/IP version 6 is disabled.

TCP/IP version 4 is configured to use DHCP. This works, but the B205 repeats the DHCP query every 2 seconds, flooding the DHCP server and clogging the logfiles.

I have now disabled DHCP and entered static data, but this is not desired.

What can I do to stop the B205 from flooding the DHCP server?
