Dear Friends,

It is required to find out the following information using the perl
under linux environment.

1. Wireless info:
- Wifi card description
- Driver version
- Band
- Client manager version
- PSP mode

2. Wireless connection :
- Associated, authenticated
- gateway IP Address
- Link speed
- Channel
- Security level

3. Current connectivity status

If someone gives some info (Like : Perl library, Perl function, and
