Wi-Fi on iPhone goes in and out

On my iPhone the Wi-Fi always goes in and out what do I do.

There are 2 possible causes. One, (unlikely) the Wi-Fi chip in the iPhone is bad. Bring it to the genius bar at an Apple Store. Two, (much more likely) you're Wi-Fi signal isn't strong enough. Try standing close the router or connecting to a friends network. If it works better when you do that, your know your signal isn't strong enough. The only way to fix this is to buy an extender.

  • Sprint Iphone 4 goes from 5 bars to No service and Searching? I called sprint and they tried everything on their end and told me to reset the network settings, even resetting the entire phone, and nothing helped. I read somewhere that the antenna is touchy on these phones and wearing a case may help? I would like to hear any fixes and if anyone else has had these issues. It worked completely fine the first day I had it and then it just started losing service for no reason.
  • My Wi-Fi goes out every hour exactly? Anytime I turn something on (xbox, iphone, ipad, laptop, ect.) I have exactly one hour (to the second) till my Wi-Fi cuts out for about 5 seconds and it disconnects me from everything. But as soon as I try and reconnect it suddenly starts to work again. This is getting continually frustrating and I was wondering if anyone had any idea on how to get this to stop. I'm using a Netgear Wi-Fi expander so I get better connection. Does anyone have any ideas?
  • My iPhone screen goes black and won't come on but if I press the screen you can hear the key bored? I've only had this iPhone for 2days! The screen comes back on after a while nut it keeps going black
  • My iPhone 4s randomly stops sending iMessages and only goes to text message? So I have been texting my friend all day and then randomly my iPhone switches to text message instead of iMessage, like it was using before. I have a strong Wi-Fi connection and I also have unlimited data. My internet works when I go online with my phone, but the iMessage still won't work.
