What's the exact error message you receive?
It seems you are offline...
Can you also check this process before you reply me...
Check if you can connect TV to your wifi router on a open network which means without a password. You have to set wifi network without key by login to router. You can set password ***** wifi network after it..
This process helps to confirm whether TV connects to wifi network atleast on a open network..
Please update status
waiting to hear from you
