We have a wireless router connected to DSL and a desktop computer. At least 7 computers connect or uses the same internet connection through the router. I heard that one or two computers/laptop sometimes cannot get through the internet and their computer will display a message that says, there is a conflict in the ip address. Do you have any idea of the problem? How can we resolve this problem? KEEP SMILING = NEIL (red star 89 @ 1530)

Ok, the IP Conflict means another computer/laptop has the same IP address as the one getting the conflict message. Usually means there is no security set on the router, and DHCP is not set. If in fact there is no security on the router such as WPA, it should be set immediately. Another case would be that one of the others systems has been assigned a static IP, meaning, it was put in manually. If the router i set to DHCP and assigns an IP address that has already ben manually entered, you will get a conflict. I would release and renew the ip adress, setup security, then try to connect again.

oh i know what your problem is. one of your computer is set to use a specific ip address. base on the picture your using a linksys router. the ip address that it provides to your computers usually starts with 192.168.1.100. now let's say you have 7 computers. if you will be checking their ip address their ip address will be like this: 192.168.1.100, 192.168.1.101, 192.168.1.102 and so on. now if let's say you open just one computer and instead of it set to obtain an ip automatically which is the default setting but set to use a specific ip address like 192.168.1.101 - will this work - YES definitely because it is one of the ip addresses that is provided by your linksys. but here is where the problem would start, once you open the second computer - which is set to obtain an ip automatically it will try to pullup the same ip address -192.168.1.101 and not 192.168.1.100 or 103. why because linksys thinks that he still hasn't provide this ip address because only one computer is connected and it thinks that the ip address he provided was 192.168.1.100. it is really confusing and it is really very hard to explain. the best way actually to solve this is to check every computer wireless or wired using the router and check if their network card is set to obtain an ip automatically. if not set it to automatic and that will fix it. and also make sure you enable your wep key which is the security key for your wireless so that no one can tap to your connection. the reason for this is there is also a possibility that the one tapping to your router is set to obtain a specific ip address conflicting with one of your computer. have a good day:)

Ahh so correct! If I may add another reason for setting up the WEP encryption is that say someone DOES tap into you wireless, and is pretty knowledgeable, chances are they can get into your router, as neilchua said the default IP for the linksys is 192.168.1.100, now if they are connected via your internet, know the default IP for a linksys, they would most likley know the Admin user and password. You see, if a computer savvy person gets connected to your wireless, they know it is not secure and most likely, if you have not setup security , then it's likely to them that you have not setup a user or password, and they can use the factory defaults! Good luck!

i have already gone with the process of resetting the router to the default settings and reconfiguring it. now we are secured with wep. but still, there is one unit here that still to be reconfigured for it has static ip address. thanks a lot neil.

Sounds like the router doesnt have enough DHCP address's to give out thus when you try to connect to the internet though that router you get a ip conflict error. go into the router config and make the ip range larger for the dhcp assigned ip addresses.

All you have to do is to hold the reset button of the router. Run the Initial set-up cd ( make sure to follow the steps carefully) after running the Initial set-up cd. Tried to perform power cycle turned off the modem first, router, and the computer, wait for 3 min, turned -on the the modem, router and then the computer wait for other 3 min. I'm sure it will work.!

No problem you can connect up to 15 users using your router.You will getbetter speed if you do like this....Use wireless only for one or two laptops and connect any 8port switch to the one of the 4 ethernet ports of the router and connect your 4 pcs using patch cables to that switch.and connect your remaining 3 pcs to the remaining 3 ports of your router .Now you will get better speed than wireless connection speed.

I am not so sure about this way but I guess it is your speed in the DSL is the problem and the only way to solved the problem about your internet connection then you have to go to th company to have an additional speed........

hi neildc, I hope you will be getting tips and opinions from members who knows about that topic! Sorry I have no idea about it!

Hi Neil, You may have to get in touch with the service provider, you cannot use the same ip address for two computers on the account and at the same time, I hope that will help. Tamara
