Author Topic: Assigning static ip to printer? Mike Heenan Phenomenal Film Handler Posts: 1896 From: Scottsdale, AZ, USA Registered: Mar 2000 posted 11-15-2010 10:48 AM                     My folks have a Canon Mx870 wireless printer, and it tends to "pause" after a few prints jobs. I generally have to reset the router to get it to print again. I read up about this printer and they recommend giving it a static IP. My folks have a belkin N router, and I went into it's home page, but couldn't figure out where to assign the IP. Anyone else have a problem like this?  |  IP: Logged Mark J.

In other words you have to tell the device to NOT use DHCP anymore, and assign it an address (outside of the DHCP scope) manually. The other option you sometimes have depending on the router is to tell the DHCP server in the router to assign a particular address to that device's MAC address. That way when the printer boots up and requests it's address from DHCP the server will recognize it and always hand it the same address. We generally do that for devices that we manually setup anyway just in case they lose their configuration for some reason and reset to factory defaults - at least we know they will have the same address when they boot up. I know how to do that in a Cisco router, but I'm not sure about how to do it - or even if you can in a Belkin router.  |  IP: Logged Randy Stankey Film God Posts: 6539 From: Erie, Pennsylvania Registered: Jun 99 posted 11-15-2010 11:22 AM                     One thing to be careful of... Be sure that the static IP assigned to a given device does not conflict with any others. If your router/modem uses DHCP to assign IP addresses to devices on your local network, it is possible that it can assign your chosen static IP to another device. That will cause IP conflicts and all sorts of rotten things can happen. Let's say you assign your printer an IP of xx.xx.xx.15. As long as the device stays on-line, the DHCP system of the router will reserve that IP and won't assign it to any other devices. However, if your printer goes off-line and another device comes on-line, the system MIGHT assign that address to the new device. Then, when your printer comes back on-line with its preset IP, there will be a conflict. The thing you need to do is to make a setting in your router/modem so that your chosen IP won't ever conflict. I have a Westel modem/router. If I go to my settings panel (192.168.1.1) I can either shut off DHCP all together or I can limit the range of IPs that the router gives out. If you shut off DHCP, you will have to manually set the IPs for every device on your home network. This might work for situations where you only have a couple of devices. But, if you have lots of devices that come and go, it could get unwieldy when you have to set IPs by hand all the time. On my router, there is a way to assign a range of IPs to DHCP and the rest will be manually set. My Westell is set to assign IPs between xx.xx.xx.15 and xx.xx.xx.47 via DHCP. All other IPs have to be assigned manually. It is highly unlikely that I will ever have more than 32 devices on my home network at any given time. In my case, it is a simple matter to be sure that any manually asigned IP address is outside the range of xx.xx.xx.15 and xx.xx.xx.47. If I do that, I won't have to worry about conflicts. Just to be safe, If I ever have to do a manual IP assignment, I do it in the xx.xx.xx.128 to xx.xx.xx.255 range. If I ever need to keep track of more than 127 IPs at my home, there are other problems to worry about besides DHCP. To change the printer's IP there should be a few ways to do it. One, you can use the printer's front panel to print out the configuration page. Your IP address should show up there. You can then, go into your router and block out that IP so it will not be assigned to anything else. (Assuming you can get into your router's config page.) You can also use your browser to go to the printer's IP address. It should pop up with a config page where you SHOULD be able to set the printer's IP to something that won't conflict. You MIGHT have to connect to it via a wired ethernet connection to make the changes. I don't know that brand of printer. Other than these generalities, I don't have much else to tell you. I bet you're already up to speed on everything else I mentioned... Aren't you?  |  IP: Logged
