How is the actual network throughput? If it is fine, then actual link 
quality is probably good, and the low values displayed just a cosmetic 
problem caused by a wrong interpretation of the results reported by the 

driverloader slightly adjusts the values to accommodate different and 
slightly incompatible ways that  various GUI utilities interpret the 
numbers reported by drivers. You could try adding a "#define 
/usr/lib/driverloader/modules/GPL/netndis.c (in the generic version) 
and recompiling the modules with dldrconfig -ka to see if it helps.
