I have an iPhone 4 and last week the wi fi signal strength symbol was not showing up at the top. I read things such as turning airplane mode off and on but it didn't work and after about an hour it randomly came back. Today it has done the same thing and I have not been able to get wi fi back so I have to use 3G. Does anyone have a solution for this?
IPhone 4 WiFi Connection Problems?
That could be so many different things actually.first of all believe it or not other devices such as wireless security cameras and such can interefere with a phones wifi capability. So be mindful of this, also there are suchthings as wifi jammers now days that folks like to use to be all covert and incognito.your best bet though is to make sure that you are on a wifi network that is compatible with the iphone security key. I have noticed that most phones will not hook up to a wifi router that is using the wep2 type of security key.the best type is the regular wep it doent usually give problem.
Sorry to say that it is nothing to do with that. It's not a localised problem, MILLIONS of iPhone users have reported Wi-Fi failures in the past month alone; it's all down to Apple's latest operating system and they should be ashamed.
