WIRELESS ROUTER SECURITY
When you power up the wireless router and the LEDs are ON then the router appears to be OK and this also applies to the DSL or cable wireless modem. To check if the modem is configured to your ISP settings and the modem connects to the Internet, connect the modem with a LAN cable to your laptop and check if you can get into the Internet. To connect to your wireless router, it needs the router's wireless settings configured and also needs the wireless cards in all the laptops and or computers to be configured with the router's wireless settings. Then the laptops and desktop computers can communicate with your wireless router.
