Once you log into your router click on the wireless link.
On the bottom of the wireless page click security.
Here you can change your wifi security.
Once done just click apply and the that's it.

Note: Once you change the wifi security settings you will have to reconfigure your wireless devices with the new wifi security.

Hello,
Download and install free open source Router Commander software from www.routercommander.com. After problem happens, see in router commander's syslog what the reason is.

You could setup two different profiles, one for each wireless router.
Configure your home wireless router with a different SSID and encryption setting to the office wireless router.
Then configure the wireless card in your laptop with two different profiles, one for the office wireless router and one for the home wireless router. When you want to use the home or the office wireless router, just call up the profile you require.

open the access points in the internet explorer
in it set the wireless security to WEP and provide the network encrypted password

You need to log into the wireless router either by a computer that successfully connects wirelessly or by physically connecting with an ethernet cable. Once connected, log into the router by open a web browser (Internet Explorer, Mozilla Firefox, Google Chrome, Apple Safari), and typing the router's address (usually 192.168.1.1 or 192.168.0.1) into the Address (or URL) line. The default usernameand password is usually "admin" & "admin" or "admin" & "password". Once successfully logged in, look for a tab or link that says "Wireless" or "Security". You'll be able to change whether security is enabled or disabled, and the password associated with it. Your security options are WEP or WPA (or WPA-PSK). WPA-PSK is the most secure, but WEP is also an acceptable choice. Select the security option of your choice and either enter text into the passphrase generator or choose your own password and type it into one of the security key text fields. If you use a password that is not a plain english combination of letters and numbers, be sure to write it down so that you can enter it as needed on other wireless devices that need to access your router (ie-pda phones, game consoles, laptops, desktops, etc). Be sure to save changes so that the security settings and password is saved.
Let me know how you make out.
