Netopia DSL Router (DHCP Server) was giving address to connect to Internet

How did you connect the computer to the router. If you are using a DSL modem it will have a DHCP server in it that is allocating IP addresses across your network. If you added the router to the computer via a hub or network switch what is the computers ip .
address. Remove the WI FI router - turn off P.C and then Go to cmd or dos prompt if windows based system and type in ipconfig and press enter to see if ip addresses are 10.0.0.2 if they are your dlink router uses 192.168.0.1 so you need to make the dlink router ip addressand subnet setting to match the Modem ip addresses of the DHCP server. Change the ip address of the dlink router to be 10.0.0.2 and change the modem to allocate DHCP IP addresses from 10.0.0.10 to 10.0.0.255. Only do this if IP addresses are 10,0,0,1 to 10.0.0.,254 on the desktop p.c with the dsl or cable modem connected.without the router being involved. (you may need to ask the ISP what the user name and password is of the modem and it should be ip address xx.xx.xx.1 so type this into a browser to change the modem settings. 10.0.0.1 or 192.168.0.1 just remember if the modem is 192.168.0.1 so is the Wi router from d-link and you will have an ip clash problem)
. How do you do this by ethernet connection from only the desktop directly with only the Wi FI . router. Go to a internet browser and type in the URL 192.168.0.1 and then change the router ip address to match what the DSL modem DHCP issues..
Page 14 of Router instructions see http://files.dlink.com.au/Products/DIR-615/Manuals/DIR-615_C2_Manual_v3.10.pdf
in the manual it states to use a direct ethernet connection for the setup program but you need to be connected to the internet for it to work but if the IP addresses are wrong or clashing will have no internet. You also want to set the modem as the DCHP server and disable the DHCP server in the set up of the wi fi tand set the WI FI router default gateway as the ip address of the Modem. if any DHCP server options in the WI FI router sert to the modem ip address. .

plug the computer into the modem testing dhcp
if it gets internet the modem is the dhcp server
the plug into router by itself disconnected it from modem testing dhcp if gets ip address and no internet it's the dhcp server
dhcp can be done by the modem or router. I bridged mode the modem and let the router do dhcp. of course the router must be pppoe for dsl. been years since I had DSL, hope it helps

The ip address conflict is likely caused by a manual IP address that is entered into the printer that is overlapping with an automatic address that your router is giving out. Either switch your printer to DHCP so it gets an automatic address, or reserve the address in the router's DHCP list or pick a manual address to assign that is outside of the range of the DHCP server. Most router will start at address XXX.XXX.XXX.100 so if you pick an address between 20 and 40 then you should not have any more issues with conflicts.

Hi
I get that you was connect to the internet by wireless connection .
so in you connect with access point connected directly to dsl modem so try to restart the access point and try to connect again ...and reset the wireless in your device... may be it works .

I think this problem occur cause access point or DHCP server cant give your device new IP address..
so you must clean the DHCP leased addresses by restart the access point or enter to server and do that from DHCP .

else you can try to assign static ip address has the same network id with router ..
for example : if router ip is 192.168.1.1 so you must assign ip address like :
192.168.1.x while x number between 2 and 254
hope that helps you

DHCP SERVER in Router and DHCP server in Wireless Conflicting - Set WI Fi DHCP router leases to say 192.168.0.10 to 192.168.0.100 and default gateway as 192.168.0.1 and on the router set the router's ip address to 192.168.0.1 make the Wi Fi router address 192,168.0.2 . Set in the router the DHCP address leases to 192.168.0.101 - 192.168.0.254 and default gateway 192.168.0.1 or deactivate one of the dhcp servers and rely on one dhcp server like the routers and then deactivate the wi fi's dhcp server.

Title: Setting-Up a Wired Computer to Obtain an IP Address Automatically Article ID: 4033
Configuring a wired computer to get an IP address automatically will enable it to get an IP address from a DHCP server. Instead of manually entering the IP settings which will consume much time, performing this procedure will ensure that the computer will get the correct TCP/IP settings.
Configuring a computer to get an IP address automatically is useful when:

• Connecting a computer to a network with a DHCP server. Ensuring that the computer is getting the correct TCP/IP settings.

To configure a computer to automatically get an IP address, you have to check the TCP/IP properties of the Ethernet Adapter installed on the computer. Follow the steps below for instructions.
NOTE: Make sure the wired computer is properly connected to a network with a DHCP server.
Checking if the Computer is Set to DHCP
NOTE: The instructions provided below only apply to Windows 98, ME, XP and Mac operating systems. If you are using Windows Vista, click here for instructions. For Windows 7 users, click here for instructions.

1.) The setup needs changing
2.) first off the dss-24 is a network switch not a router
3.) all of your pc equipment should be pluged into that device.
4.) chose one port as an uplink to your att modem
I think your problem is that the new modem is only giving out one ip address. So what ever first pc is turned on that is the one that grabs the address.
5.) you will most likly need a router to take the one ip address assigned via att then dole out additional ones. Remember the dss-24 is not a router. It simply connects everyone together. Each device still needs an ip address given from somewhere. Your old cable modem probibly did that but your new att dsl most likly does not.hence the new router will do that.....
to set it up do the following
2.) Find out the ip setup needed for your dsl service
A.) gateway ip
B.) primary & secondary dns server ip`s
C.) subnet mask
3.) get into the setup of your new router and then plugg in
all of these values using a fixed if address in the router
4.) connect routers wan port to one of the modems port. u may have to use a cross cable or straight look at the link lites to find out if they are talking to each other
5.) make sure that the routers lan side is setup for DHCP
6.) connect one lan port off the router to an uplink
of the dss-24. Then reboot everything
7.) viola it should all work internet on evey machine and file sharring.

You can use below steps to install router

ROUTER SETUP

1. Please remove all the connections from the router. Connect power to the router and then connect a cable from the computer into any of the 4 lan ports on the router. Make sure the modem should not be connected to the router or to the computer.
2. Open up the Internet Browser (Safari, Internet Explorer, Mozilla Firefox, Opera, etc.).
3. Put http://www.routerlogin.com/basicsetting.htm or 192.168.1.1 address bar. press enter
4. Login to the router with the Username as "admin" and Password as "password" (please note that the Username and Password are case sensitive).
5. Click on lan ip setup under advanced.
6. Change the lan ip to 192.168.10.1 and under use router as a dhcp server change the starting ip as 192.168.10.2 and ending ip as 192.168.10.51, click apply and click ok for any popup message that arise.
7. Once the browser display some error message like CANNOT FIND SERVER, ACTION CANCELLED etc, Connect the dsl modem on the wan port of the router and restart the computer.
8. Power off the dsl modem and the router after making the connections.
9. Power on the dsl modem and wait till the dsl light comes on, then power on the router.
10. Open a web browser (Internet Explorer, Mozilla Firefox or Safari).
11. Access the router (http://192.168.10.1).
12. Login to the router (Username = admin Password = Password).
13. Click on Setup Wizard and then select "Yes" and Click "Next" on the detection window.
14. It should give you a "Dynamic IP Detected" or "pppoe detected"(type the Username & Password of your dsl account in case of pppoe detection) and then click next.
15. Click Apply.
16. Logout of the router.
17. Open up another browser window and try to access internet.

Please rate the service positively if issue resolved
Thanks for using Fixya

It will be one of two things or both - either your computer is not setup for DHCP or your router is using the same IP address as your ISP or both.

To check ISP IP address connect your computer to your modem then: from start => run => CMD (hit enter after this)
a command window opens, type "ipconfig /all" without the quotes.
The line with "IP address" gives you your ISP IP addr.
Compare this with what you get from your router manual if they are the same then do the following:

To configure your computer to use a DHCP IP address, go to the Control panel => network connections => Properties (right click on your default connection) => double click Internet protocol (From general tab) => (a new window pops up) from the general tab ensure that "obtain an IP address automatically" is selected.

To change the IP address of your router check your manual and do the following:
IP Addr => 10.10.1.1
Sub net mask => 255.255.0.0
Default gateway => IP address from your ISP
Make sure to the router is set to act as a DHCP server.

You should be up and running.

The Netopia Is a business-class router. Not clear from you question are you running Small Business Server or Windows Server 2003? If its the former, it has a wizard that will configure your LAN & the Netopia.
You can configure the Local IPs on the Netopia in the DHCP settings in expert mode.
The VP (VOIP?) phones are acting as a DHCP server & re-configure the network to their defaults.
Any 1/2 decent IT person (witth some real qualifications) could figure straiten this out...beware of "Techs"
