Windows 7: IP Adress Conflict

IP Adress Conflict



What does that mean? I have a PC, which is connected to the Router via a cable, besides that, two more notebooks use the Wireless network provided from that very router.

Looking forward to your help!

If you have assigned IP's manually (statically) it means that a device already on the network already has the one the computer with that error is trying to use.

Can you give us some info about the network setup?

Have you setup your internet connection for your ethernet card with a fixed i/p? If so, what appears to have happened is that you have DHCP setup to issue I/P addresses to wireless connections on your router. When a wireless connection talks to the router, it gives an address that is within the range setup for your DHCP server. If you then connect with a fixed I/P ethernet card and the adress of this is the same as one of those issued by the DHCP server, you end up with the message you are seeing. Try setting you fixed I/P address for the ethernet card to a free address that is outside the range set in the DHCP server eg. if your DHCP settings are for address ranges 192.168.1.2 to 192.168.1.20 then set the fixed I/P address on the ethernet card to say 192.168.1.30. Give that a go and let us know how how you get on.

Thanks for your prompt answers.

The problem is, the wireless network was set up by an acquaintance of mine 3 years ago. Since then, I tried many times to access the Control Panel, but never could I succeed because of the forgotten password.

The things have worked perfectly for three years, it was just a few days ago I that I got the message several times on the startup.

Until I find a solution to the Network Control Panel Access matters, does the problem seem to be serious enough not to be left behind?

Thanks again!

I have a wireless router at home, and i set my network connection to "obtian IP automatically". If i choose "Sleep" not "Shutdown" after using my computer, and meanwhile another device start using the network, then when i log in again i get the same messege "IP Adress Conflict".

If you contact your ISP, they should be able to give you the setup details for your account. Then download a copy of the manual for your router and find out how to reset it to factory defaults. Once you have reset it, follow the instructions for setting it up using the settings you got from your ISP. That way you will be in control of your network and not your acquaintance. Other than that, follow mak74 's advice above and select to obtain IP automatically. This will mean that your computer will get a new I/P address from your routers DHCP server every time you login. By resetting your router to your settings as suggested you can make sure that enough I/P addresses are available for use.

Well, I talked to the person who has set up the Router and he told me the only thing I have to do is to make the network assign IPs automatically. The good thing is, it has to be done from the computer, not from the Network Control Panel, as he says. So, would you please give me some instructions?

What about if you disconnect anything that is connected to the network except for your pc and the router. The router will have a reset button somewhere on it, press and hold for 30 seconds. If no reset button then google the model of the router for a manual on how to reset it. From a command prompt type ipconfig. The default gateway shown is the ip address of your router. Type the ip address into a browser window and then youll be able to access the router config, then allow the router to auto DHCP. If youve only got 2 other computers linked to the router theres unlikely to be a problem, but as per the other posts to be sure set their ip addresses to something outside the dhcp range of the router.

Click on network icon at the taskbar, click "open network and sharing center", at the left click "change adapter settings", right click on "wireless network connection", choose "properties", at the "network" tab click "internet protocol version 4(TCP/IPv4) then prorerties, then choose "obtain an IP address automatically" "obtain DNS server address automatically", and if you'r network provides IPv6 follow the same procedure click "internet protocol version 6(TCP/IPv6) then prorerties, then choose "obtain an IPv6 address automatically" "obtain DNS server address automatically".
Good luck

I suggest you follow the advice in ripperita's reply as this is setting up the issuing of addresses by the router. Mak74's advice will allow you to set your computers end up, but I would advise that you deselect the "internet protocol version 6(TCP/IPv6)" as this sometimes causes problems and you are unlikely to nedd to use it soon.
