I have an iphone 4s running OS6.
My wifi stopped working in that I could select it but there were no wifi sources listed.
I saw online that a network reset might fix the problem, so I did a network reset and that did fix the problem. The wifi was working and wifi sources were listed.
However, the cellular data was also reset.
So I entered the cellular data:
Visual Voicemail (no change)
(other setting unchanged)
Then I turned by phone power off and on.
Now I have a problem. The wifi button is disabled (greyed out in the off position) on my phone, so I can't turn wifi on. It seems that entering the giffgiff cellular data has caused this.
Has anyone seen this specific issue? Can anyone offer any useful advice please?
