Changing the router password is one of the first security precautions one should take with their computer system. This is because routers come with standard passwords, so if the password is left unchanged someone could easily hack into the system.
Check security setting for wireless network in your router settings. Some routers allow to see the key, some mask it with asterisks. If your router masks the key (in router settings), you have to put a new key, if you want to connect more computers.
Most routers have a reset switch in the back. You need to connect the computer to the router using a LAN Cable. Press and HOLD the reset button (you might need a pen) until the lights reset on the router. This will reset the router's current settings and reset the router to default. From there, you may need to reset your routers passwords and other settings. Best way is with your connected computer to your router, using your internet browser's address bar, put in the ip address displayed on your lan connection icon. Most routers have a setup menu flashed into the hardware. If it asks for username/password, check the model's website for default username and password. From there, you should be able to reestablish a new password in the security tab for your router. (Also, if you have an install disk, then you can install the same stuff to your pc where you can modify your settings, which may be easier for the less technical)
New routers have advanced firewall features capable of blocking most security threats.
Implement firewall hardware as well as firewall software on your computer/computer network and implement the use of Access Control Lists (ACLs) on your network's routers.
192.168.1.1 is not your WEP security code. You need to enter that into the address field of your web browser to access its settings page. In other words, put it into your web browser the same way as you would put www.answers.com into it. You will need to enter the administrator password to get in. The default on most routers is "admin". From this point, the process changes depending on what model and brand of router you have. For most routers, there will be a button or link to a wireless security settings page. The WEP key will be there. You need to do this from a computer directly plugged into the router with an ethernet cable, though, as without the WEP key you can't access the network at all wirelessly.
Check with the router manufacturer. But you should be able to access your wireless settings by entering your routers IP address in the web browser. In the future, try installing the software it came with or download it from the manufacturers website.
Routers connect via your computer's ethernet input.

No, in order to reset settings most routers have a reset button that you have to press and hold. Sometimes you may have to power cycle the device as well.
All routers, including wireless routers must be connected to your Internet modem to work correctly. Routers usually include installation discs that will help you with the installation of the router to your network. At least one computer/device needs to be used as a control system so that you can change and test your router's settings. If you do not have an installation disc check with the manufacturer for a free download of the installation software.
