Wireless configuration sir , i am using unbuntu 7.10, and i am not able to access my wifi device nor i can access wired connection , so what should i do to make my wifi work

Boss i will tell you how top set up a wireless connection on your laptop through a Wi-Fi network. You should however know how to configure your settings manually to be able to connect your Wi-Fi card to the wireless network.

The first step for the configuration is to determine what SSID, Channel, Mode and WEP you are using.
What is SSID?
SSID is the acronym for Service Set Identifier which is the name of your wireless LAN made up of 32 alphanumeric characters. This service can be set manually through your client network settings. In order to enhance the network security system, some wireless access points will automatically disable this feature.
Wireless Channel Selection
Access points or so called APs mechanism is used to automatically detect the channel selection. Your network can hence have various APs that will manage each channel selected and make their power regulations. A wireless station will be load balanced across the access points in order to enhance its bandwidth.
WEP
WEP is a short term for Wired Equivalent Privacy which is a system of data encryption used in a wireless network in order to allow authorization control for a 802.11 wireless local area network.
How to set up your wireless connection
Nowadays, a modern notebook is built with a wireless modem that has a wireless power system and an activation button found on the keyboard. This button will allow your laptop to connect or disconnect with your wireless modem. If you do not have your user manual to be able to identify this key, here is what you can do: as a toshiba user please follow it.. For Toshiba users

• Those using a A100-078 can use the sliding button on the right-hand side of the laptop
• M40 and M70 users can use the ON/OFF antenna-like button.
• unbuntu users either of avobe features.
