Hi.  I have just purchased an Inspiron 3650 (3ZRY482), and downgraded to Win7.  I've ironed out all the drivers but one.  It is :

PCI\VEN_168C&DEV_0036&SUBSYS_020E1028&REV_01
PCI\VEN_168C&DEV_0036&SUBSYS_020E1028
PCI\VEN_168C&DEV_0036&CC_028000
PCI\VEN_168C&DEV_0036&CC_0280

Ive tried a dozen different links, but each has failed for one reason or another.  Do you mind giving me some direction?

Thanks,

Jim
