Router hook up to another router

[GTT1]

Staying at a place that has internet and the apartment I am in has the cable modem and it is hooked up to a router which feeds internet to 3 other apartments.

Is it possible to take my connection from the router and hook it up to the incoming connection on my router then use the wireless function of my router with my laptop?

Tried but get no connection.

Possible IP conflicts between the 2 routers?

That shouldn't be an issue, the laptop still goes through the router which is assigned whatever IP it was originally given he has the router functioning with DHCP.

Check your router to see if it actually leased an IP to your laptop or ping your router from your laptop. I doubt your laptop and router is communicating and not actually an issue with having a router connected to a router

You'll have to turn off DHCP on your router. This basically changes the router into a switch. You can only have 1 router giving out IP's on a subnet.

The correct term is access point.

Thanks I will give that a try.

Just plug your cable into port 4 on your router. DO NOT PLUG IT INTO THE WAN PORT.

Then disable DHCP and you are good to go.

Go into router settings first, disable DCHP, then plug in the cable from main router to port 1 of your router, just dont plug it into WAN, and you'll be good to go!

Isn't that what I just said?

Also change the default IP of the second router, turn off upnp, "gaming mode", or whatever useless features it might have if you're using it as an AP.

[Gee]

If you disable DHCP, you don't need to worry about the default IP.

[infamouskid]

dhcp has to be off. your also forgetting nat and firewall should be disabled on the second router behind the modem as well.
otherwise you will run into issues with certain protocols and services.
it just requires more configuration for the 2 to work in harmony.
dhcp, nat and firewall should all be handled by router 1.
op what are you trying to do exactly?

He wants to use a wireless connection for his notebook. Says so in his original post.

Is it the same thing if he plugs in LAN port and assign a router IP??

My bad, lol, i clicked post reply at the top before i scrolled down.

I am assuming you mean WAN port.

Actually, it is probably better to plug it into the WAN port, he can actually segment his network.

But to do this, he has to make sure that he is on a different subnet from the original router.

Go into the router and set the IP to something you that you know is far off.

192.168.9.1

The plug in the cable to the WAN port and configure your router with a static IP on the WAN port (Cable Modem setting). Depending on your primary router, the subnet will probably be

192.168.0.1 (D-Link)

or

192.168.1.1 (Linksys)

I would choose an IP that is outside the scope of the DHCP Server. Assuming the primary router is a Linksys, I would use

192.168.1.250

The downside to this, you may have trouble with BitTorrent or routing specific applications to the WAN port.

If you have access to the original router, I guess you can configure it to do what you need.

By doing this, the other three users cannot see your wireless or your computer on the network.

+1

I'd recommend this as well just for the additional "layer" of protection.

[railgrinder]

i'm not sure if anyone's asked yet, but what model is your router? perhaps i can download the online manual and look through the configuration options for you.

on some routers there's an option to change from routinng to bridging mode which should resolve this.

Thanks everyone, I set it up like Gee suggested and it is connecting.

i would not even go with the wan port setup on the second router. too many service restrictions. i would plug into port 1 of the router. assign the same subnet and assign static ips. much easier to manage. and you still have the freedom and security of all the clients that wish to use whatever services.

What I did was plug it in the WAN port then assign each router an IP address. It works but I don't know if it has any effects on the speed or not. My speed shows 100Mbps eventhough my router are gigabit.

lan speed is gigabit. wan speed will always be 10/100.

[mexanh]

I meant the "internet" port of the second router. I'm always confused between LAN & WAN :o

internet port = wan
local network port = lan

[mexanh]

Thanks for the clarification infamouskid :). I saw some people get gigabit internet speed. I wonder how they can get if the WAN is always 10/100. I pay $90/month but the max speed I get from Rogers is around 5Mbps :(. Don't know if my connections are wrong or not.

it does not matter what the link speed is cuz in the end your broadband connection will always be less then 20 megs. like i said gigabit cards are only for transferring files locally within the network. you will no difference in downloads if i were to download a file using 802.11g and if you used 802.11n. it will always be the same speed if we have the same internet connection.

This would be epic fail though if you want to share files among the entire network.

I clearly stated that there would be service restrictions with this setup. Unless he has access to the original router, he will still have restrictions regardless of which methods he uses.

That is the whole point. Why do you want to share files with three other strangers in three different apartments?

[mexanh]

I tried to hook to port 4 and disable DHCP but it has a big hole. No security for wireless on the second router unless you turn it off. So I put it back the way I had before:

I hook the main cable (branched from a port of 1st router) to "internet" port (of second router) then assign different IPs for each router. Of course I have to watch out for the number of user on the first router. Say I have 1-100 of the first one then the IP for the second router should start at 101 or it's better to use 2.1, 3.1... instead of 1.1. It works just fine for me with all the security I want. However, I can only share files with those machines that are hooked to the same router :(
