How do I find out if someone from outside my home is using my wireless network

First, Grab this users guide:

http://www.2wire.com/pages/pdfs/2701HG_user_guide.pdf

Second, Access the interface:

Open a Web browser entering http://gateway.2wire.net.

To access this page, your organization must have the Remote Management feature
enabled. If the feature is not enabled, an error message will display when you click the link to
access this page. See the guide on setting this up, though you should be fine with your current settings. Assure that you can log-in to the Remote Management Feature using the user name and password originally established, or follow the instructions if you are unaware of these credentials.

Then access The Local Network - Address Allocation page shows the name and IP address of each device on the gateway’s local network, and allows you to create DHCP mappings for each device.

This will show all the PC's connected. If you number is higher than the PC's that you have, you may have a free-loader.

View your manual about setting up MAC filtering to prevent this from occurring. Also, please consider setting encryption or "WPA"/"WPA2" up on your router to prevent unauthorized access or viewing of your traffic.

I hope this information helps.

If you have any further questions or concerns, please let us know. If it has been informative, please take a moment to rate the solution.

Hi,
You need to log on to your router/s and look at the log.
You should also change your security settings in your router/s so this won't happen again.

Good Luck!
