IP address conflict.

[SOD'EM]

Every day or two, I get a thing comes up on my screen saying there is an IP address conflict. There are other computers using the same IP address (or something like that). I have just ignored it as my sons computer uses the same wireless router. I was just wondering if it was possible somebody else (not from this household) could be linked to my router? Is there a simple way I can find out. There are a couple of reasons I have decided to try and find out. The first being the fact that I had to reset my wireless router sometime back and I have to use a universal password at the moment (no idea how I can change that). Another reason is because recently I have been losing my wireless connection (albeit, only for 20 seconds or so but can be a pain in the arse if I'm in the middle of a game or something) a few times a day lately. The third reason is the fact that this never used to happen, it's only the last couple of months really.

you've got a pc set to a fixed ip then

 

make sure they are all set to get IP by DHCP

 

if you look on the rooter homepage

it will give you menu options and somewhere will be a tab that allows you to view the wired and the wireless assigned IP's [pages will be separate areas for each]

 

then look at the device name that has the conflict see if its a named device on your network

Thanks dx. I'm not sure how to get to the router home page. I am with Virgin Media if that helps.

typically 192.168.1.1 or 1.100

This post is very old. Maybe this will helps:

 

To solve this problem:

• Click Start/Control Panel/Network Connection
  
• Right click on the concerned connection[Properties]
  
• Select "Internet Protocol (TCP/ IP)" then properties
  
• If the "obtain an IP address automatically" is checked and you still have this problem check the bubble "Use the following IP address"
  
• Enter the IP address, Default Gateway (depending on the range supported by your ISP).

no fixed IP's will not solve the issue here

as how do you know its not already assigned?

Easy way to check as suggested is to try to login to the router as suggested at 192.168.1.1 or 1.0 or 1.100 or 0.1 or 0.100, it should be one of them, although I think the last may actually be the cable modem (that connects to the thick cable).

 

Virgin use Netgear routers, the default login is name:admin password: password or virgin, or is the name virgin ?, try the variations, and as suggested make sure DHCP is selected, you can also click attached devices to see who's using it.

 

It is unlikely even if someone else has hacked in it would make this error as it would still give them a new IP addy

 

IPconflicts occur whwen two people manually choose the same (static) IP but it sometimes occurs on DHCP systems, ipconfig /release and ipconfig /renew should fix it.

SOD'EM,

 

I realise this is quite an old thread now, but are you still having problems with your IP address?

 

There is a fairly simple method of securing your home network, which would alleviate your concerns re neighbours 'borrowing a cup of internet' - called MAC filtering.

 

If its still bothering you, I'll post up some instructions.
