How do you secure a router? My wifi does not always work when using my laptop.?

Drag out the manual

plug your laptop into the router using a cable

access the router

enter the user name and password

go to the wireless settings

enable security

use WPA encryption

give your router a unique SSID

save your settings

disconnect the cable

connect to the router using the new SSID and pass phrase

Once that is done go back into the router using the cable

change the user name and password

save the settings

If you are really worried, enable MAC ID filtering

Enter the MAC ID of your laptop (be careful - blow this step and you will have to reset the router and start over)

now only your laptop can access the router

Have fun

What's the model of your router? Securing it will not resolve your WiFi not always working when using your laptop though.

Pull up a command prompt (black screen) and type in the words ipconfig and hit enter key. Your default gateway is what you want to type into your browser to get to the log in screen. Look on bottom of router and google the default password and username for it. Should be fairly simple once you see the interface of the router. It's just some typing and clicking.
