Why isn't the Wi-Fi on my iPhone 4 working, even though the signal is strong?
It worked this morning. It worked when I went out for lunch (Starbucks has free Wi-Fi, duh.). And it worked when I went shopping (at Target.
However, when I came back home around late afternoon it stopped working. I have Wi-Fi in my house, and even when the signal is strong, it just keep loading it. No usual checkmark that shows it works. The Wi-Fi works fine on my brother's 3DS and we already checked the home computer router. I just don't know what's wrong.
The profile might be corrupt. Try to remove it and let it reconnect.

- Why isn't my Wi-Fi signal as strong on my iPhone? A few weeks ago I had great Wi-Fi connection, for years. But now I can't catch Wi-Fi from anywhere in my house unless I'm in the room where the router is… I got a new router but as soon as I leave the room (where the router is) my Wi-Fi signal drops! It's not only happening at my home but also at my gram gram's house and my sisters house. It's really frustrating. So I know it's not my router it's my iPhone.
- Why is my car playing music from my iPhone, even though I didn't do anything to make that happen? Also, I was watching a YouTube video at the end of yesterday, and when I got in my car, the title of the video appeared in my car audio display screen. Could I have watched the video? The car has a backup camera, so there's a TV screen in the car. (BTW I have a 2015 Honda Civic LX)
