TRy doing it a couple of times ... Do it exactly in this order....
1. Go to settings .. safari .. And "clear history and website data."
2. Close safari by double clicking on the home button and swiping the safari window up off the screen.
3. Go to settings .. General ... And "reset network settings". .. You will have to renter your wifi router password after this
4. Restart your iPad holding the home button and power off key till you see the apple logo ..
I still get the occasional safari crash on links at certain web sites. One way around this is if you know it always happens on a certain page ... press down and hold on the link until a menu comes up and then select "open in new tab"
