Wifi shield (FI 250) dont connect wifi house, HELP

good day
I’m using Arduino Mega 2560 and the shield wifi fi250 , however the same are not communicating , tried to update the firware unsuccessfully searched several codes on the internet and also without success, could help me ?

That’s a common problem: Please see this reference of SoftwareSerial Library . Not all pins of Mega can be used as softwareSerial pins, so choosing right pins while using Mega with shield.

And maybe you can visit the usage between GPRS Shield and Mega.

Could someone post a configuration (jumper settings, pin connections, …) for this shield to work with the Mega2560 ?
I’ve tried for days to make it work but still no success !
