unwired ubuntu..

wireless network for Desktop PC.
Sounds crazy .. isn't it?
Actually, some crazy and not-so-conventional stuff to be done in it.

Well, managed to do it somehow..
lot of thanks to kushal.

Used D-link wireless card and LinkSys AP.
Some other useful stuff is here and here.
Now BIG headache was easily solved by WiFi-manager.
Later on, found one more tool to scan all the APs.
Tomorrow, I will do some basic routing table and removing some bugs.

PS: one strange error coming again and again:
If I use wired as well as wireless interface togather(even for different LAN and different purpose), My http/tcp connection are being reset. It might be at proxy/gateway level or at my own computer PHY.
