I have an LGG3, and it upgraded to Marshmallow. I immediately started having issues with staying connected to wifi. (Every 15 seconds to a minute it would connect/disconnect) I called Verizon and they went thru and had me do a soft reboot on phone. Had me reset phone back. Nothing worked. They sent me a replacement phone, and it was fine until it did the updated as well. I contacted LG, and they said to send my phone back, they'd fix my phone and send it back to me. I got my phone back, and it wasn't my phone (as I had recorded the IMEI number before I sent it in.) When I called them on it, they said they repair a phone, and send another one back to the consumer. (Which wasn't what I was told in the beginning.) When I got this phone and started it up, it already had the marshmallow in it, and low and behold I'm having the same issue. (In the beginning, I also contacted my internet provider, they pinged my router and it is fine, as no one else is having problems with their phones either in my home.) Everyone is pointing their fingers at everyone else, saying it's not our issue, but, here I am stuck with a phone that won't stay connected to the wifi. I'm getting really frustrated, because there is no fix, and no none is willing to help me fix the issue on my phone. My family and I share data, and I love to play music, and I'm always having to watch my data to make sure we're not going over because of this issue. Like I said, I've done everything that has been asked of me. I've researched the internet looking for a fix, and there seems to be nothing. What can be done to fix this issue?
