Solved hub to router problem help!

August 24, 2012 at 08:43:41
Specs:
My house gets 2 IP address in total. thnx to hub I was trying get my own ip address for my room.
First ip goes to Router 1 and Second ip goes to router 2 or my computer. So when I connect two computers from the hub, only one computer will get internet access for this reason I've been trying to connect Router.

fig 1

modem -> hub1 -> Wireless Router 1 -> internet O
\
--> hub2 -> Wireless Router 2 (or just router) ->internet X

this is how they are connected. (hubs are those that connects internet by AC power)
only problem is Router 2 can't send internet because it cannot renew ip address.
Router 2 says it is getting internet but when i connect my computer computers says no internet connection. I tried going into my router (192.168.1.1) and changed somethings but no work.
but interesting enough.. if I connect my computer straight from hub 2, the internet works.
so
modem -> hub 1 -> hub 2 -> computer O
modem -> hub 1 -> hub 2 -> Router 2 -> Computer X


can some plz help?
oh bytheway modem -> Router -> hub 1 -> hub 2 -> computers O <- this works with mutiple cmputers but I just dont get why it won't work if fig 1...

Ok, well if you have two IP's then we should be able to make this work.

First, you're probably using switches. Hub's are obsolete technology and nobody manufactures them anymore. I doubt that's what you're using. Regardless, even if you are, this should still work.

I would however removed #2 from the mix. Your setup should look as follows:

Internet >> Modem >> Hub/Switch >> Router's 1 & 2 >> Clients

Daisychaining switch #2 into #1 makes no sense since you could be plugging a network cable directly into Switch #1 and from that into Router 2. All you do by sticking Switch 2 between Switch 1 and Router 2 is add another useless hop.

I suspect the issue is your setup on Router 2. Ensure the WAN configuration on router 2 exactly duplicates Router 1's config with the exception of the IP address.

I cant access to the internet throw that router but router actually says it is getting internet but just can't get ip.

To me this says "incorrect DHCP configuration" Ensure the DHCP server on that router is configured correctly with IP's in the same subnet as the LAN IP of said router. Also, the default gateway IP and DNS IP configured in DHCP for clients should also be the LAN IP of that router.

Unless you're paying for more than one IP address, you'll only have one. Typical home highspeed setup is the client gets their IP address settings automatically from the ISP's DHCP server. In most cases these days, that acutally registers to the MAC address of whatever device you have connected to the modem (PC, Router).

If you have a typical "home" highspeed package, what you're trying will not work.

To do what you want you'd have to upgrade to a package that includes "static" IP addressing and more than one IP. This usually costs more, of course.

Why do you think you need "your own IP address" Why isn't connecting to the existing Router and getting internet through it good enough? Perhaps if I know what it is you're trying to achieve I can help you.

first off We do have 2 ip address our internet comes with two ip.
and my family has been having trouble with internet so I was testing it and with about 6 computers plus small devices into one router with one IP my family decide to try seperate that and see.
but like i said the hub actually works but when I connect router to hub, I cant access to the internet throw that router but router actually says it is getting internet but just can't get ip.

"I just dont get why it won't work if fig 1..."

Because hubs don't do routing. You need a layer 3 device connected to your modem.
