I got my LG G3 and I'm having issues with WiFi in my house. I upgraded from an S3 and my wife still uses her S3. I'm trying to backup all my pictures to my PC over WiFi on the G3. I have an app that does it automatically when I plug the phone in. I've also tried ES File Explorer with the same results. I cannot seem to finish the backup as the G3 loses WiFi signal and errors every time. I've tried the same apps on my S3 and my wife's S3 to the same PC over the same WiFi and it doesn't fail. I've restarted the G3, I've turned off WiFi, and I've even "forgot" the network and re-connected. I don't have "Avoid unstable connections" or "Wi-Fi signal weak" turned on. I've rebooted the router and, additionally there's no overlapping signals on my wifi channel as I live with hardly any neighbors. I've tried setting the phone down right next to the wireless router with the same results. The WiFi icon never goes away and if I hit retry the transfer starts again immediately, it just seems to be losing connection enough to stop the transfers of files every time.
