[driverloader] Signal Levels for WG511v2 (Marvell chipset)

[Linuxant support (Jonathan)]

Hi,

it is possible, as you mentioned, that they use a proprietary way to 
transfer the link quality value and this is why the Windows XP wireless 
configuration tools report inaccurate values just like DriverLoader.

You could contact the vendor of your wireless card and ask the question 
to see if this is the real source of the problem.
