Intel (R) Centrino (R) wireless N 1030

I have a dell XPS 15 L502X fitted with the above radio card.  Right from first purchase the wireless would not connect.  After visits from an engineer the machine was taken back and then replaced.  Since then i have had repeated dropping-out of the wireless - at least three or four times.  This appears to happen after Windows updates for some reason - anybody know if this is right?  To get the wireless working again - iam an ancient computer inadequate - I have had to go to Dell support who have on each occasion taken remote control of my laptop and after hours on the 'phone and on-line activity managed to get the wireless up and running again.  Earlier this week Windows had a major update and , guess what, I have lost the wireless connection again.  Does anyone have a simple solution to this? or is Dell support the only source of action to get a fix.  I have been using Dell computers ( I am posting this through my desk-top) for a number of years but if I cannot get a resolution to this problem I will not renew my machines with Dells.  I have a 20 year old Toshiba laptop which still works (slowly) but has never had a Wireless failure.  What is wrong with theses Dell supplied wireless cards.  Reading briefly through the community pages I see lots of similar problems to mine being reported.  Get it sorted Dell.   Can anyone help?
