Description

It's worth understanding more the characteristics of the MAX8997 and the MAX77693.

This could help in understanding if and how we can make external USB devices more reliable. That is needed as the internal WiFi chips don't work with free software at the time of writing.

The MAX8997 is used at least in the Galaxy SII (I9100) and the MAX77693 is used at least in the Galaxy SIII (i9300), Galaxy SIII 4G (i9305), the Galaxy Note 2 (N7100) and the Galaxy Note (N7100).

Some more background information can be found in the WiFi wiki page.
