Losing connection to L26500

[eahicks]

Anyone shed some light on why I keep losing connection to my printer, and why every time I check my IP settings, they have changed? Either the IP address changes, or the default gateway changes, on its own. I am at a loss. I can't print anything because when I do, the print starts, and then cancels and tells me no data is sent to the printer, and then I check the IP settings again and something has changed.

There is a place on the control panel or through the computer interface to set your printer to a static internal address.
If it looses the connection and it is set to automatic, the router may assign it a new address not necessarily the same one.
Check the manual for setting the ip address, be sure it is not already being used by another computer, printer etc.
You can run an internal ip scan with something like angry IP to see what addresses are already being used.

I have done all that. I have always set it manually. I have changed the IP address to several open addresses. Something is happening that is not only changing the IP address, but also the Default Gateway. Subnet never has changed. And the default gateway seems to get changed to the what the IP address is, which obviously will not work.

If the network settings are defined to use Static Addressing on the printer itself (entered through the front panel on the printer), there is effectively no way that the printer's IP Address can change, barring a hardware malfunction. Issues with your router, switch, or cabling cannot change a static IP Address that is set on the printer itself.

Most routers that are using DHCP will begin serving addresses at a lower area of the range (usually 1 or 100), and go up from there. If you set the printer manually, using a Static Address to a very high number (between 245-252 or thereabouts), there is little chance for duplication with DHCP addresses set by the router.

Well I just went in to the router settings and DHCP is on, of course, but had a starting number of 192.168.0.1. I set it to start at ....100, but kept my printer's IP as a lower number (.30 in this case). Seems to be ok for now....we'll see. I assume it won't touch that since it is below range.
