salve. Io ho un iphone 4 con iOS 7.1.2 comprato a dicembre 2013 e da circa 10 giorni con qualunque rete wifi persiste un problema riguardante il segnale, in quanto anche a 4 metri neanche dall' access point prende molto poco e spesso sparisce. non saprei proprio come mai, ho provato anche a raffreddarlo ma niente. Qualcuno sa aiutarmi? grazie mille.

thank you but I have just tried every of this options.
Below is a User Tip about Wi-Fi issues. Suggest starting from the top and working down. Maybe one of them will help.
1) Perform a Forced Restart: Hold down the Home and Wake/Sleep buttons at the same time for about 15-20 seconds until the Apple logo appears. Allow device to restart.
2) Reset Network Settings: Settings > General > Reset > Reset Network Settings. Rejoin the Network again.
3) Reboot Router/Modem: Unplug from power for 2 minutes and plug again. Update Router Firmware (check manufacturer’s support website for a newer FW). Also try different bands (2.4 GHz and 5 GHz) and different bandwidths (20 MHz recommended for the 2.4 band). Channels 1, 6 or 11 are recommended for the 2.4 band.
4) Change to Google's DNS: Settings > Wi-Fi > Click on the Network, Delete all numbers under DNS and enter 8.8.8.8 or alternatively 8.8.4.4
5) Disable device prioritization on the router if this feature is available. Also disable any VPN apps and test Wi-Fi again.
6) Determine if other Wi-Fi devices on network are working well (other iOS devices, Macs, PCs).
7) Try device at another Network, i.e., neighbors’, public coffee house, etc.
8) Backup and Restore the Device using iTunes (ask for additional for details if desired).
