For most people, just using DHCP is fine. (Dynamic Host Confugration Protocol, it automatically assigns IP addresses, and tells your computer which DNS server and gateway to use).

Works great for getting IP's to computers.

He seems to be having a problem with his router and modem having the same IP address. This does happen from time to time (both want to use 192.168.1.1 for example).

Somewhere in the router there will be a spot that you can change the default IP address of the router. Look for somewhere to change the LAN IP or a Networking Tab or something similar. I looked around the internet for a bit to see if I could find anything but I couldn't. Just know that there is definately a way to change that address, it's just a matter of figuring out where to go to do it.

Yeah this is pretty sucky. I know there's a way to change it on my Linksys though. Just disconnect the router from the modem tonchange it obviously.

OH, I dont think I totally understood his problem! I do now though.

I think for Netgear routers, the page to change the router's IP address is called "LAN IP Setup"

Default Re: Basics on configuring IP addresses for a wireless router

still doesnt work
my ips for the modem and router are different
modem: 10.0.0.138
router: 192.168.1.1
this is strange
when i run the wizard on the routers interface it detects my connection as static ip when it isn;t
and then asks me for my DNS
i checked ipconfig and ipconfig/all and my DNS was shown as 10.0.0.138
which is my modem's IP
im confused =S.... i'm getting online help from netgear to see if they kno wat the problem is

I'd also call your ISP. They might be more help than Netgear.

What IP is your computer getting? If it is not getting a 192.168.1.X address then something may not be plugged in right and that may be the problem.

Also some IPs do MAC filtering and require that you let them know that you have a router so that they can update their modem to provide internet to the router instead of your computer.

That's strange. The modem and the router should not be sharing the same IP address. The 192.168.1.x is a sub-network for just your home. But anyway as you've posted your modem is not sharing the same IP so it's something else.

My guess is something on your ISP's end. They haven't registered your MAC address or some BS like that.

^^It's possible that his modem is giving out the same range as his router is trying to. I've run into this where the modem is using a 192.168.1.1 for it's lan port and the router tries to use the same address so the computer gets confused.

Shouldnt the modem be on the same subnet as the router? as in... Router = 192.168.1.1, modem = 192.168.1.2 and PC = 192.168.0.3?

Default Re: Basics on configuring IP addresses for a wireless router

Not always. Again I don't know how to exactly explain it, but I've run into an issue with a particular ISP in the area that has their modem set to 192.168.1.1 and if you have a router that uses that same subnet, you have to change it to 192.168.2.1 in order for everything to work. I've run into it know about 5 or 6 times.

It took me like 2 hours to figure it out the first time, but now any time I run into this ISP I change the router IP and it works perfect.

Ah, that's strange!

Most of the time in the UK, people use routers with the modem built in, so i've not had much experience :P

Really? My friend has that and let me say, they blow chunks. I find that most of those arent exactly top end so you don't get the best performance, plus I enjoy tinkering with routers. I think thats sort of a mess waiting to happen combining those two in one.

I've never had problems with them - why do you think it's a mess waiting to happen? As long as the components are up to spec and not going to fail after a year or so (and pretty much all of the known brand ones I've used have been fine) there's no reason why it shouldn't work as well as an external modem, and if it's cheaper that way I'm all for it! It's the same story as routers with wireless access points built in - as long as their designed properly then there's no reason why they shouldn't work as well as plugging in an external one.

Of course, if we're talking about badly made or ill designed hardware then things are different and the same applies if we're talking about a large corporation network rather than a small home network. But on the face of it there's nothing wrong with designing things that way

Well my main gripe with them is you don't have too much oppertunity to move the device around for optimal placement. Like with my modem and router seperate I can move the router/AP around and place it in a better space but my cable modem is pretty much stuck in its current spot unless I want to call the guy up and have him cut more holes in my wall. You could always get another AP but still.

Have we tried restarting the whole shabang? Unplug the Modem and the router. First turn on the modem, wait for a few seconds for it to fully come up online and then turn on the router. Possibly any IPs hangin' around messing things up such as the DNS server having the same IP as the modem?
Just an idea...

I'd contact your ISP before you start messing with the modem. Netgear is probably just looking for an out, blaming it on something else. Have you talked to the ISP at all about this problem? They should be able to help you.
