Keep your router on WPA, WEP can be broken in lower than a minute next to the right hacker's tools. WPA give you much better wellbeing.
Depends on the model.
In the wireless config page on the router you should know how to switch it to WPA, I would recommend WPA2.
try this...
type "http://192.168.1.1" in your pattern browser.
If adjectives go according to plan, this should access your router. From near you should see plenty of options/tabs that would enjoy the settings you are looking for.
Many routers hold failure to pay passwords close to "Admin" as the username and "Password" as the password. Sometimes "Admin" is used as the password as ably.
Hope this help some. If it doesn't work, try to locate your IP address and put that contained by the pattern browser instead of the one I give you.
Depending on the router you are using, the address 192.168.1.1 usually refers to a Linksys router and the failure to pay password is admin next to no username. If you enjoy a different router than a Linksys, refer to your encyclopaedia or you can check out for one online.
WEP, wired equivalent privacy, used to be the preferred surety when it first come out. Unfortunately it's not as safe and sound as the newer WPA, wifi protected access encryption.
If you haven't already, the first piece you involve to do next to any wireless router is to progress your admin password. If someone be competent to receive your signal they could try the 192.168.1.1 next to the admin password and after lock you out of your router by shifting the password.
