rhess :

Hello, are you available?

rhess :

Hello

Customer :

yes

Customer :

hello rhess

rhess :

I'd like you to start by click on the Start Menu.....in the search box, type cmd and hit Enter on your keyboard

rhess :

a black windows should pop up where you can enter commands. let me know when you are here please

rhess :

Hello?

Customer :

here but black box has now gone

rhess :

Okay, it should still be in your taskbar though. Below this window you are looking at now to the right of the Start Menu button, do you see a little black box that says C:\_???

Customer :

yes

rhess :

ok, you can click on that to get back to that window

Customer :

ok should i do that now?

rhess :

Hang on just a minute

rhess :

I need you to do the following.....but it's going to cause you to lose your connection for a moment

Customer :

ok

rhess :

Follow these instructions exactly......

Customer :

ok

rhess :

With the black window open, type ipconfig /release and press Enter on your keyboard. Then, type ipconfig /renew and press Enter on your keyboard.

rhess :

the first command is going to remove the IP address from your computer, at which time you will lose connection. The 2nd command will give your computer a new IP address, and hopefully this will remove the conflict

rhess :

Any luck??

Customer :

didnt lose connection-nothing else has happened that i know of

rhess :

you did leave the chat and come back in

rhess :

you may not have noticed that you lost connection, but i think you did

rhess :

how many computers are you running in your home?

rhess :

There is a way that we can test if this worked

Customer :

one

rhess :

Do you have a wireless network? Any gaming consoles (PS3, XBox)?

Customer :

wireless. no gaming consoles

rhess :

Does your wireless require a password to access it?

Customer :

no

rhess :

Ok....I'm pretty sure you have a neighbor accessing your wireless network

rhess :

An IP address is a unique address that each computer is assigned within a network

Customer :

I do have a neighbour that spends a lot of time on his computer

rhess :

If any device on the network shares an address, this can cause an assortment of problems, including messages about a computer having the same IP address as another computer

rhess :

If you have no other devices in your home, I'm fairly confident somebody is "stealing" your internet access. It's actually very common.

rhess :

The best way to protect from this is to protect your wireless network with a pre-shared key that requires a password. Unfortunately, because of the technical nature of setting it up, it's beyond the scope of the service I can provide you. If you contact your Internet Service Provider, however, they should be able to set this up for you

Customer :

ok will try that thankyou

rhess :

In the meanwhile, the steps we performed should resolve the issue for now. But I would still take action to secure your network. If somebody knows what they are doing, they can use your unprotected wireless internet to access files on your computer.

Customer :

scary-can they also access my prepaid dollars?

rhess :

It depends on how good they are and how malicious their intent is. Honestly, I wouldn't worry too much......more commonly, people just use free internet access to browse the web and save a few bucks on paying for their own service.

rhess :

There are ways to tell what devices are connected to a network, but again, that requires advanced knowledge and differs from router to router.

Customer :

do they use up my gbites in doing so?

rhess :

If you are on an internet plan that has a limit on data usage, then yes

rhess :

Let me stress the point that this is not definite...There's a slight chance I could be wrong, but based on what you told me and how common wireless stealing is, this is the most likely scenario

Customer :

I am so will aquire password pronto

Customer :

ok, i wont go making accusations yet then but will get password

rhess :

Unless you have any other questions, I am going to Opt Out of the question to allow another expert to review your issue. I'm pretty sure I am right about this, but a fresh perspective may provide insight that I am unable to. If you no longer get the messages, then my solution fixed the problem and you need to get the network secured. If I am wrong, perhaps somebody else will have the correct your problem. I just want to make sure you get the best service possible. If I am right, you can Accept my answer so that I get credit for it. Otherwise, I hope your problem gets resolved.

Customer :

thankyou for your expert help and advice rhess

rhess :

No problem. Have a great rest of the day!

Customer :

does this mean my problem has been resolved?

rhess :

Hello, I just wanted to follow up with you to see if my solution fixed your problem
