How to set up security? - Linksys Computers & Internet

If your computer is connected to a network or the Internet, it is advisable to use computer security tools, such as a firewall, to protect your computer from unauthorized access or viruses. Windows operating systems come with a built-in firewall, malware protection and Internet security. These settings are automatically configured to the factory's default settings when you purchase the operating system. To alter the settings for these security features, access the Windows Security utility through your system's Control Panel.

Open the "Windows Security" utility by opening your "Start" menu and selecting the "Control Panel" option on the right-hand side. Windows XP users can click on the "Security Center" link in this window. For Vista users, click on the "Security" option, and then click on "Windows Security Center." Click on the "Windows Firewall" option to change the settings for your firewall, if you are using XP. You can turn the firewall on or off, and also configure which programs are allowed through the firewall. Vista users should click on the "Windows Firewall" link in the left window pane and click on the "Change settings" link. In this window, you can block programs from passing through your firewall and grant access to new programs. Click the "Internet Options" selection to configure your Internet security settings. You can raise or lower the security level for different zones using preset configurations, or you can create a custom security level. You can also reset the Internet security level to its default settings. Click on "Automatic Updating" in the Windows Security Center to configure your system's update settings. In Vista operating systems, click on "Windows Update" and "Change Settings." You can configure your update settings to automatically check for updates daily or weekly. You can also set a convenient time for your system to update to prevent interruption. Automatic updating can be turned off by selecting the corresponding option toward the bottom of the window. Select the "Malware Protection" option to edit malware settings if you are using Vista. This option is not available in XP's version of Windows Security Center. You can turn the malware protection programs on or off using the arrow to the right of the "Malware Protection" bar. Click the "X" button to exit Windows Security Settings.

hi, I think you may try WPA2+AES setting while setting up wireless connectivity, it will ask network key to setup. It is more secure setting for wireless usage.

Your network's security needs to be set to the WEP OR WPA security setting, as those are the only security settings that the 3DS is compatible with. Here are step by step instructions on how to change your security settings.

Hi there! here's how you can do that. Hope it helps. :)

Security Settings
All of your phone's security settings are available through the Security or Restrict and Lock menu.
Accessing the Security Menu
1. Press > Settings > More... > Security.
2. Enter your lock code to display the Security menu.
Accessing the Restrict and Lock Menu
© Press > Settings > More... > Restrict and Lock.

Unless you set your browser up for high security, this certificate is bogus. Rarely does a security certificate notice appear on yahoo without having set your browser up for high security.
Lower your security if it set to high and see if the message disappears. If your browser security is set to normal, then this is a bogus certificate for a bogus yahoo site.

By setting up WPA2 encryption you are securing your wireless network from unauthorized access.

go to the wireless access point admin settings (not on your wireless adapter on your laptop). then check wireless security settings. if you see something there such as security key, that is the security key that you need to set up on your laptop. if security key is not visible, try to see if there is an option there which says unmask to show the security key, then copy it to your laptop. if all else fails, change the security key in the wireless access point and change all the wireless adapters that connect to it accordingly to the new security key you set it up.

My security settings are not supported or are not compatible
If your network name (SSID) is displayed on the Nintendo DS with a gray locked icon (pictured below), then your router is set up with security that is not supported by the Nintendo WFC. Playing multiplayer over the Nintendo WFC is only compatible with the WEP security setting, even when playing with a Nintendo DSi. WPA and other security settings are not compatible. Solution:
You will need to either change your security settings on your router to "WEP" (recommended), or disable all security. For information on changing the security settings of your router, click here.
