Why is the WiFi on my iPhone 4 so slow?

[Oliwia]

Today my iPhone 4 WiFi became really slow, it doesn't really connect and when I try to send a message on Facebook it takes like 30 seconds, the WiFi on my laptop is really fast. What happened ? Please Answer.

As iphones age they start to malfunction. The first thing to try is a reboot of the phone. Hold the power button and the home button together until the apple logo appears. Wait for the phone to reboot and then retry your internet/wifi

DON'T reboot it like Joey said please that's only for when it freezes and other must do times, which is NOT this time. First, it's the wifi signal you have may not be that strong and having multiple devices on a wifi signal slows it down. Second what I believe it is, is the wifi router is probably a different or more profile settings than the iPhone accepts. Since most wifi routers are update to accept newer wifi signal types. Since whenever you hear 802.11n a/b/g/n and things like that and the letters are those profiles accepted and the iPhone's wifi signal doesn't have some of the newer stronger profiles which more and more routers have since it's like 3 and a half years old now and may only accept a couple of those wifi profiles. The last thing is it's always good to just turn your wifi router on and off every few weeks or months just to give it a refresh. It's more of a router and wifi profile issue than an issue with the iPhone itself at all.
