Hi all, I bought a Sony X900F last June, about a weeks ago, my tv cannot connect to Wi-Fi. I thought maybe it was my wifi router issue, but my phone, ipad can connect to wifi. I reset the TV but it still cannot connect to wifi. Does any of you know what the problem is

I think its hardware issue, maybe your wifi module is broken.
