how do i fix ip address conflict so my two computers can use the same dsl connection?

Question

I just hooked up two computers to my DSL modem via a network router. I then set up the home network in Win XP on both computers and restarted both. Both computers are giving me a Windows system error "There is an IP address conflict with another system on the network." I then tried repairing the local connection on each computer - trying to get a new IP address for both computers. That didn't work. The only way i can get on the internet is if I unplug one computer from the network router - no IP conflict that way and the internet works fine with just the one computer. So how do I get both computers on the internet?

Thanks for the first two answers, but they are not helping me so far. I downloaded the Linksys sd205 manual, and it is simply "plug in the wires" and therefore not much help. "Repair" did the release and renew, but it hasn't helped after two tries on both computers. It took me a while to figure out what you meant by Default Gateway, but I found that under the cmd prompt "ipconfig /all." when i pull it up on the internet "http://66.141.186.69/", it tells me it can't find the page. Now what? More detail in the answers would help. I'm one of those users who knows just enough to blow up everyone's computer on the block! lol

Answer 1

Well I hate to say this but YOU NEED A ROUTER, the SD205 is just a five port switch and has no routing ability so it will not work to do what you need.

A router will supply seperate IP addresses for all computers on the inside system and will connect them to the Internet using the ONE IP that you have.

A switch will just connect all computers together and attempt to get an IP from your ISP -- which just supplies ONE IP thus all the conflict problems.

Interesting problem. I used to work in internet support, and this error does usually come up when people use a wireless router. I would check your tcp/ip properties and see if something is hard coded in your computer. Does Teton use DHCP to allocate IP addresses, or do they use static IP addresses for clients? To check to see if you have a hard coded IP: Click 'Start' and go to 'Control Pannel' Open 'Network Connections' Right click your LAN (local area connection) and go to 'Properties'. Find TCP/IP in the list of 'This connection uses the following...' Highlight it and push the 'properties' button. Most ISPs use DHCP, so if that is the case you should have the radio button filled in to "Obtain IP address automatically'. If your ISP uses static IPs, the radio button will be filled in to 'Use the following IP address' and the fields will be filled out. You should find out from Teton how that info should be filled out, because you may have an IP address configuration setup in here that was from your previous ISP.

Depends on the router. What you really need to do is make the router give out DHCP IPs. This means the router gets an assigns each computer a different IP and simply uses it's own to connect to the modem. Type in the default gateway IP into your web browser and it should bring up a screen that will allow you to edit your router settings to enable DHCP.

Answer 4

WIRES supposed to be crossover cables
to check default gateway do cmd prompt and type ipconfig/all and press enter you should see your default gateway and ip addresses---- if they have the same default gateway ip address the router is good if both computers have the same ip address theyre in conflict-----solution assign manual ip addresses to both computers they must be near the range of the default gateway ip addresss if your default gateway is 192.68.3.1 then assign one computer 192.68.3.4 the other 192.68.3.5 (example).

need your comments on this thanks.

Answer 5

try accessing the settings of your router by reading the manual
adresses vary but mine is 192.168.1.1 username and pass is usually admin or it could be username is blank and pass is admin or vice versa then go into the settings of computers hooked up and try telling it to realease the ip addresses and everything

good luck
