Configuring a adsl2 router

Hi,

I had switched my isp. The new isp had provided a cisco dpq2160 cable modem which has a ip address of 192.168.100.1. I have a desktop and two laptops so i need to configure my Binatone dt845w adsl2 router.

When i connect my desktop to the modem the ip assigned is 27.7.58.XX, gateway - 27.7.56.1 subnet - 255.255.248.0.

I assigned the same to the adsl wireless router. The modem is connected to the ethernet port of the router and then connected to the desktop. So the router settings are the same as the previously mentioned settings.

The router assigns the same ip the desktop and i'm able to connect to the internet only on the desktop. My mobile is assigned the ip of 27.7.58.156 but mot able to access the internet. If i change the router ip or the local pool range nothing works.

How come the modem IP is in different range compared to the desktop IP it assigned. When accessing the modem with its Ip it doesnt show any settings other than this. (Ofcourse with values which i didnt include.)

Name
Modem Serial Number
Cable Modem MAC Address
Hardware Version
Software Version
Receive Power Level
Transmit Power Level

I know that the current settings are wrong. Please guide me to configure this. Thanks in advance

By looking at the set up guide for the dpq2160 I can see that it's not just a modem, it's actually a modem/router and for some reason this isn't explained very well at all in the products set up page. It does show the Modem's Ethernet port plugging directly into a switch which means it has DHCP capability and is actually a modem/router.

Since it's DHCP capable and you are trying to use another router with this modem it's required that you go into the set up page for the Binatone and turn off DHCP, because at this point you are really only using the Binatone as a switch. You also don't want to use the WAN port on the Binatone, plug the dpq modem into the LAN port on the Binatone.

You should not need to set up any type of static IP's as the DHCP from the modem/router will give the Binatone it's own IP after you turn off DHCP.

If you need to set up the Binatone as a access point you can access it through it's new IP which will be assigned from the modem/router.

Nope not able to do what you have mentioned. The modem doesnt assign ip addresses.
To be clear I disconnected my router and directly connect the modem to my laptop running Ubuntu it was not even able to establish a wired connection. IMO I think that they hardcoded the IP to my desktop while activation. Is it right? is it even possible? the modem is just for the conversion i guess.

You can usually shut down the modem/router for a few minutes or use the reset button, when the lights come back up on the modem, plug in the router and it should pick up an IP from the modem/router. After that you just need to type the newly assigned IP into the URL on your browser so you can set up the router.

You might try calling your ISP for information about their modem/router or how to change the hard code to your desktop. Usually the mac spoof setting or a reset will fix that.

If you scroll down the page I posted a link too for your modem/router, go to 15-32 about half way down the page.

You can see the modem plugging directly into a network switch then it goes straight to the other networked machines, this means that your modem has DHCP capability which means it's actually a modem/router.

You can even see where they plug another router or access point into the network switch directly. This is where your secondary router should be picking up an IP. You can also plug directly into the router from the modem/router but you will want to use the LAN port on the router only, LAN port to LAN port, don't use the WAN port on the router.

I found an article which mentioned that the mac address of the desktop is used for security reasons. So only when the modem detects that mac it assigns the ip. This is the reason my ubuntu laptop was not able to connect. I found the mac spoofing option in the router, changed it to the mac of the desktop. Now the problem is we need to connect the WAN port of the router with the modem. My WAN port is not a usual Ethernet port it is rj11(phone). This port is small and Ethernet cable doesn't fit into that. I have a rj11 cable which i used before to split the dsl from phone lines which was used for the old isp. When i connect the that cable the modem doesnt detect the connected cable the link LED in the modem goes down. I'm sure that the WAN port should be used in this case. Check the link. Article

I'm not too sure on the phone lines but generally speaking once you come out of the modem/router's LAN port it's supposed to go from there to the router's LAN port, not the WAN port. We never use the WAN port on the second router.

I think some router's have both a phone type plug and an Ethernet port but I'm not really sure if you can get an adaptor for that.
