Someone else is using your IP

I was using my MacBook yesterday and I got a warning telling me that someone else is using your IP. The mouse started to be funny and not doing things that I wanted it to do.

Then I just let it go and then the mouse started to move around going into my history, systematically opening folders and then I just hit the shut down button.

Does anyone know of any solutions to this problem. It seems that somehas broken into my computer and has taken control

Thx if someone can tell me something to do.

One word, firewall. Turn it on.

Are you using your Mac on a home wireless network? If so, make sure your network is secured with a complex WPA2 password. Also, as -aggie- recommended, turn on your firewall and enable stealth mode.

We may never hear the rest of the story. Since this is their first and only post in the forum, there is only about a 33% chance the OP will ever post again.

Follow up.

I will definitely post what happens and what I did. If this is going to work I appreciate the help I got. And the least thing I can do Is at least let the people that helped me now if it worked or not.

I have no doubt that you are probably correct.

I am/was curious if the OP left VNC enabled with no passwd, had a Trojan installed by providing the admin passwd, or something like that.

I highly suspect that there is a lesson of caution to be learned by all of us here.

Unfortunately, none of the answers here are likely on track. They are all playing off your assumption that your computer has been somehow "broken in to".

First, it would be helpful to show us the EXACT error message. Not your paraphrase, but the exact words. And what you were doing when you got the message.

However, I can give a good guess. (But only a guess in absence of complete information.)

This message means that there is another device on your home network that has the same IP address as your Macbook. This would normally only happen if you are using static addressing and you've plugged-in the same IP address on two or more devices. The primary symptom would be flakey or completely non-functional networking on the devices with the identical addresses.

Tell us about your home network. (Router, etc.) Do you have an iPhone, iPad, Internet-connected TV, etc. etc. etc.?

Normally, today, in a home network, each device will be set up to "obtain an IP address automatically" (i.e. get an address from a DHCP server). Your router is a DHCP server, and will give each device a unique address. You need to make sure your router is set up for this (normally is by default) and that it's been set with a sufficiently large "address pool" for the number of devices (and possible guest devices) in your house.

Should you, for some reason, have more than one router, (I have a second WiFi router in my living room, for example, to provide complete coverage) you need to make sure you are running DHCP on only one of the routers.

Feedback of my first post !

Thx for all replies.

Things I have done !!!

(GGJstudios)
I have turned on the firewall and enabled stealth mode.

I have checked the password for the router and it is now WPA2 password.

For the DHCP server it is turned on.

About my computers and router.

i have several of macs in the home and mac mini. I have also iphones and ipads. One windows computer (Hope no one nows where I live )

I have two routers but they are not the same wireless, i have different password and name for different router.

Facts about the problem:
When this happened i was in the same room as the other person and we both started to watch the screen while someone as i would prefer to say was browsing through my computer. I was propably browsing hotmail or Facebook when it first happened. And the second time when it happened I was just browsing Facebook and some other stuff hotmail and news pages. This computer is mostly used for browsing and not working with programs and other stuff.

Question:
Lets say i have opened and installed some **** from a hacker that wants to get access to my computer and I have trojan on my computer. How can i know, how can i get rid of it ???

I will keep posting If there is something new that happens. And I appreciate if someone else has a input to this threat. But until now there has been no strange activity on my computer and I hope something worked out, but if it happens again I will start to post again and I will try to record it to my phone and upload on youtube so everybody can just see this strange sh**.

Regards
Gummi

I'm in a hotel using their wifi and got the same message as OP. Creepy to say the least. I did not lose control of my cursor but I quickly shut down my wifi, enabled wifi again and got the message that someone else was using my I.P. address. I am know tethering off my Xoom tablet's 3G (ducks before fruit/beer bottles are thrown at me for using a Xoom) ahem, anyway... I went to my Settings/Security and Privacy/Firewall and set up my firewall to block all incoming connections except those required for basic internet services. Has another guest at this hotel accessed my I.P. address? Should I be worried?

Use ransom characters for your passcode for your router. Mine is over 25 random characters, the more the better. I also have my SSID hidden, not sure it helps, but I'll try anything to help.
