Hi Andre, I decided to force an "update" actually by "changing" the device and choose the option to allow me pick the device drivers manually (of course not recommended). I installed the Atheros's AR9285 drivers which the effect of removing the device "Dell Wireless 1702.811b/n/g. I now have Atheros AR9285 Wireless Adapter which has been working fine since! No Freeze ups so far and performance has been good! Thanks a lot for your patience and diligence. I hope it will continue working fine.
