I have the same problem
Done that close all active apps and re boot
Done the settings - safari - clear cookies & clear history
Still safari ( crawling pages $ continue to crawl
Wifi is fine ... Other devices on wifi work fine
iPhone safari is a rocket ( touch wood )
Ipad - 2, iOS 6.1 , safari is crawling
