Linux as we know it still has many problems regarding support hardware especially graphics card, and also on some models of WiFi cards . In recent years it seems that something has improved thanks to the remarkable contribution of companies like Red Hat and Novell which spend most of their forces to improve support for Linux . Unfortunately there are still many WiFi cards that are recognized or not by default work very badly. To solve this problem very often we must either install the drivers provided by the manufacturer , or try to add some configuration to get the connection , to facilitate us this was made a simple tool called Wifix.
Wifix is a simple script which will search and install the rriver for our Wifi card is also available if you add some configuration to get the connection .
If you upgrade the kernel from 3.0 to 3.2 generic , and I riscontrava the classic mistake of detection of Wi -Fi, with this tool you can configure everything properly.
