Broadcom 802.11g Wireless Network problem?

Lenovo G430 Broadcom 802.11g Network Adapter problem? (written by oman) if you have already search and try all the blogs and forums found by google, try this one, coz this already happened to me and I found it by myself... when I found it I felt so stupid fooled by the system. Here is the clue: (written by oman) remember that there are some switches for notebook wireless before you can use it:
power switch, you need to switch this power on, located under your left-hand position.
hotkey switch, press fn-F5 for lenovo G430 or another key for other notebook.
make sure that you switch it on when hotkey displayed
that's all! have a nice weekday!
