How do i secure my belkin 54g router? we only want people who are in the house to access it

SOURCE: How do I put security on my Belkin 54g router

You set your security by enabling WEP.

When you get in the interface to configure WEP, set a pass phrase. Write down the 3 numeric keys it generates. Then connect to the wireless using your laptop, etc. When it asks for your passkey, do not enter the pass-phrase; enter one of the three keys that were generated by the router. That's the biggest mistake people make when trying to get wireless to work.

Once you've logged into the router (open your browser, and type ONLY this into the Address line, without the quotes: "192.168.2.1). You should get a log in pop-up, "admin" is the username, and the password is left blank (or is sometimes "password"), again without the quotes.

Once logged in, you have a series of menus on the left hand side, Usually large blue lines demark each section, i.e. "Lan Setup", "Internet WAN", and of course the section you are looking for "Wireless". Under each header is listed each of the pages available for that function. For example, under Wireless you'd want the first 2 items: "Channel and SSID" - this is where you set the name of the wireless network; and "Security", which is where you setup whichever one of the Encryption options you want. This Encryption key is the password you will use when connecting wirelessly to the router from a PC.

Hopefully that is enough to get you setup.

Hi there,

Connect a computer to any one of the four LAN ports of the Belkin wireless router. DO NOT use a wireless connection, use a cable.

Open your web browser and type the IP address of the router (by default, the address is http://192.168.2.1.) in the address bar and press Enter.

Click Login on the top of the page to login to the router. By default the Password is left blank, click Submit.
Click Security under Wireless menu.
Under Security, Select 64 bit WEP (or 128 bit WEP).
Select Key 1 and enter any 10 hexadecimal digits - any combination of 0-9, A-F (26 digits if you selected 128-bit as the encryption strength). You may also enter a pass phrase and have the router generate a key for you. Example (0102030405060708090a0b0c)
Apply the settings. 
Please write down the key – You will need it later to configure your and your neighbors wireless computers with the same key.
Remember to set an admin password before you close down, other vice anyone can access you router and change the setup and admin password.
