Hi, My iPad 2 has been working just fine, then it suddenly stopped seeing my wifi router. The iPad appears to be functioning normally, except for this problem (I can't get on the internet). My router is working OK (I've posted this from my laptop, using the same router). Is it possible that the 'aerial' in my iPad has just malfunctioned? Is it a recognised problem, and can it be repaired? Any advice would be gratefully received. Many thanks!
