DHCP and Printers help

Question

i have a printer (brother 2070N) that i have connected to my router and so my notebooks can print wirelessly. here's my dilemma, I first set it up a couple days ago and it worked fine. Today i can't print. None of my notebooks can't print. So i first go to printers and faxes, right click the printer and go to properties. Then i click on ports and find the printer port. It has an IP of 192.168.2.104. So i go to the router page (linksys) to see what the IP address i'm getting. Well since i'm using dhcp it has changed to 192.168.2.106. So i know i have an IP conflict. My question is how do i change it in windows so it will update the IP when it needs to. If i punch in the printer's IP in internet explorer, i get the printer's page and i see that it has the IP as 192.168.2.106. So it updates everywhere except for in windows. Does anyone know how to get this resolved???

thanks

I think what you're seeing and describing is normal DHCP behaviour - as you have different PC's or devices (printers/scanners etc) in your home network - then IP addresses can (and are allowed ) to change.

Obviously though you may need a certain device like a printer to have the same IP address time and time again - so you can always refer to it or use it.

Resolution : On your home router which is being the DHCP server - simply do a statis assign of MAC address to IP address (DHCP reservation). So for your printer MAC address - reserve the IP address you always want it to have. The DHCP server will then not offer it to any other PC or device except the printer.

So that sounds like it's going to be a fix. i just need to know how to do it. I have a linksys wrt54g router. I went through it and i must be overlooking it. i see where i can set it to static but that disables dhcp all together

I was looking at mine but i don't run the linksys software any more.i was looking in my manual  and found that online.. .i know you can do it if you run DD-wrt..

see if this works

Yeah, DHCP reservation is a pain with the WRT54G. Its located under Management on the Administration page about halfway down. I am not at home, but I think its MAC address * IP you want reserved *

Alas checking a few websites and even Linksys - it seems the WRT54G does not support nativley the simple DHCP reservation feature.....various blogs comment on this.

So you have two choices :

(1) Download a 3rd party firmware image - e.g DD_WRT which does have this feature

(2) Statically configure the IP address, subnet mask and default g/w on your printer - and then ensure the DHCP scope on the WRT54G starts higher than the printer address - so it never offers out your "statically assigned IP printer address"

I would try the 2nd choice first
