iphone 4 ios 6.1.3 wifi weak signal
Can anyone help, I have just bought a second hand iphone 4 but it looses the wifi signal if the phone is greater than 2metres from the wifi router. We have 2 other iphones in the family that work ok so its not the router that is at fault.
The iphone is on ios 6.1.3.
I had new covers fitted and at the same time the person installed a new wifi board but it did not improve the performance.
thanks
iPhone 4, iOS 6.1.3
