    I am receiving an "IP Address Conflict" message every few minutes. I received one a few weeks ago, but didn't think much of it. Now I get disconnected every time it comes up, so I don't want it to continue.

    I have a wireless router, 2 ethernet lines run into it (2 computers), and a third wireless connection (3rd computer) uses it.

    What might be the problem? I read someone might be using my IP, but because I have 3 computers in the house, I don't know if that's the cause. I've had this setup for about a year and had no problems though.

    Is your wireless network encrypted? Are you using static or dynamic IPs, or a mixture? Before you get the "conflict" message what is your IP address, and what are the IPs of the other 2 computers?

    1) Is your wireless network encrypted? -- If it is, it's hardware. I haven't configured anything.

    2) Are you using static or dynamic IPs, or a mixture? -- I think a mixture? It's the same every time I log on, but I think it changes every now and then?

    3) Before you get the "conflict" message what is your IP address, and what are the IPs of the other 2 computers? -- The IP addresses are all the same on each computer.

    "The IP addresses are all the same on each computer."

    Guess we don't need much detective work to determine the problem! Since each device on a network needs a unique (on the network) IP address it should be clear what's causing the "IP Address Conflict."

    And, as an aside, not encrypting your network is a good way to allow moochers or worse access to your internet service and to your computers.

    Would you be able to tell me how to get 3 separate IPs and setup an encryption?

    With a router there's seldom a reason to use static IPs on computers, so I suggest just make sure your router's Dhcp server is enabled and set the computers' TCP/IP properties to 'obtain IP auto' and 'obtain DNS auto.' Else if you need static IPs, then just assign different ones.

    Depending on your router you enable encryption in the wireless or security or advanced section. If possible use WPA-PSK. If you use WEP use a hex key (not a passcode that gets translated).
