When you have a network of computers, they are connected together so that every user has access to all of the shared network files. If your network isn't protected correctly, you are leaving these shared network files and the integrity of your network open for outsiders to access. You can protect your home or work network by ensuring you have a password set up, creating a network security key, changing the advanced settings, and turning on Windows firewall protection. Learn how to prevent unauthorized network access to keep your home or company network safe and protected.

Question
How do I clean up my home network?
Allan Cramer
Community Answer
It's hard to determine what you mean by "cleaning". If you mean disconnecting any unpreferred connections, you can simply change your router password. Or if you meant completely wiping everything on the network, there is usually a physical factory reset button on the router. If you cannot find that, you can access the router's menu by typing 192.168.0.1 or 192.168.1.1 into your internet browser bar. The access password/username is usually on a physical sticker on the router. Find your way to the "Factory Reset" option and presto (all routers are different, though). If you select the last option, you will have to set up a new Network if you wanted to browse the internet.

Question
How do I disable network access on my computer?
Community Answer
On a Windows computer, click on your Network options icon (next to the clock in the lower-right corner of the screen). Then click "Open Network and Sharing Center." Next, click "Change Adapter Settings," on the left side of the window. If you're on a LAN cable connection, right click on "Local Area Connection," then select disable. If you're on a wireless WiFi connection, right click on "Wireless," then select disable. To re-enable network access, simply right-click again and select "Enable."

Tips
These steps should only be completed by the network administrator. This way only one person ensures that all settings are correctly set and that all users have the ability to access the network. Passwords should be changed at least once a year and whenever an employees' position has been terminated. Ensure that all employees or family members keep the password safe and that they don't save the password in their computer if others have access to it.
Thanks
