Changing/Dynamic IP problem in Canon iR6570

[Heineken]

Hello guys, I have a network problem with an iR 6570.

Here is the situation, I have set the IP address of the photocopier to 192.168.1.100 that has to be connected to a network router with internet connectivity + 4 computers.

Next, I set a fixed IP for each of the computer with a prefix of 192.168.1.XXX. Everything works fine. The photocopiers and computers are well connected. However, whenever I set a fixed IP for the computers, the internet for these computers would not work.

When I remove the fixed IP settings from the computers, the internet work again and the photocopier networking works as well.

However, everytime the internet/router is restarted, the IP for the network router seems to change and the photocopier networking would not work again.

Is there a solution for this problem? How could I get both the internet and network printing to work at the same time?

Have you set the gateway of the PCs? You will need to set this, otherwise they will not have internet access, this will usually be their router / modem, if it is a small network. (Try 192.168.1.1 or 192.168.1.254, these are the most likely ones).

For small networks I would recommend you don't use a static IP address for any device, you have no control on what they might add or remove from the network, if they decide to change the router you may end up with a completely different IP range and whatever devices are static won't work. Best use the hostname (or computer name, as it is sometimes called) for connecting to devices and set everything to DHCP.

Additional Tip: 1)- One of the most common sources of Network setup problems is loose Cables. Be sure
each end of the cables connects tightly.
2)- Set the router i.p address as stated by ruben above; either 192.168.1.1 or 192.168.1
.254, in all cases ensure that the network mask on all the devices are set to 255.255.255.0, for the 'Class C' network address you have chosen.

I usually leave the gateway address column found in the computers blank.

I notice if i type in a gateway address such as 192.168.1.1, the internet wont work simultaneously along with the photocopier.

But I am going to try this solution again.

If you set a PC to DHCP, whatever it picks up as the gateway is what you can type in manually. Same goes for DNS. If the PCs have more than one network connection; only one gateway should be used, and it should only be entered on one of the NICs.

Thank you for the explanation. Will get back here once I get my hands on the machine.

You HAVE to have a gateway. The gateway is the network's path to the outside world.
You also MUST set the DNS servers or else domain names such as Google will not work.

Re: Changing/Dynamic IP problem in Canon iR6570

For anything you want to set up with a static address the first thing you need to do is find the DHCP range of the router or DHCP server. With that information, you want to configure your static IPs outside of that range. Dedicated devices like servers, printers, and the like are best managed with a static IP. If you're dealing with a standard commercial router, more than likely your static address of 192.168.1.100 is probably the beginning on the DHCP range. You'd be better served to set all your computers to DHCP and put the copier to 192.168.1.10 to keep it set. This will also allow you to get all of your network information to properly configure the network settings for the copier. Any connections that need to go to the workstations from the copier should, as ruben correctly stated, should be set by host name. This will also let you know that your internal DNS is working.

Is your router dropping the internet? You have two options, setup a static IP network with a proper gateway and DNS, or find out why your router is dropping. As Kronical said you have to have a gateway and DNS addresses for internet to work. Use the IP of the cable modem/DSL router for your gateway and use the default DNS for your service provider or use open DNS, a public DNS service. Using open DNs is one way to isolate your service provider or the modem as the problem. You can use open DNS even with DHCP, just don't "obtain automatically" the DNS and manually enter these: 208.67.222.222 208.67.220.220 Do you have DSL or Cable modem? DSL routers sometimes have a "keep alive" or "heartbeat signal" for the PPPOE connection. Better still is setup DSL modem as a bridge and have your router handle the PPPOE. If it is a cable modem try using the open DNS servers to isolate the modem or service provider.

enter proper gateway address & DNS in PC.

Ok guys, thanks a lot for the help. DHCP reservations solve this problem!
