My LG G3 installed the latest update this morning and now it won't stay connected to my home wifi network.I can see my network under the wifi menu and when I click connect it obtains an IP address and connects as normal. The problem is that after it connects I've been getting a good 20-30 seconds of internet and then the connection just drops and I get a message that says the wifi password wasn't accepted. When I reopen the wifi settings menu under my wifi connection it says authentication problem, and when I click on it, it asks for my wifi password again, then the process repeats.Now, I've checked that the password is correct 1000 times and there's no way it's been input wrong. I've restarted the phone, pulled the battery on the phone, reset the wireless router, logged into the router and updated the firmware, reset it again, reset the phone again. I've tried "forgetting" the network and then reconnecting to it, no luck. When my phone first connects I can look at the attached devices from my router and see my phone on there.My wife also has an LG G3 that she got the same time as mine that she hasn't performed the update on yet and she's having no issues, also we have 2 iPads and my daughters iPhone4. The only device having issues is my LG G3 since the update this morning. I've been searching a lot online and not really finding anyone else with this issue. Please help!!

I have not tried that safe mode. But why would it be an app problem when it all started after the system update on Friday? It seems like an update problem to me.

I'm having terrible problems with my lg g3 since the update Friday! I have a very hard time now getting connected to any WiFi. If I do get connected everything is extremely slow or doesn't work at all! If I want to use the internet or most of the apps, I have to disconnect from the WiFi and use data! This is really not acceptable! I loved my phone until this terrible update. Please help!

Regarding this issue, i continued to troubleshoot after my last post, and found it is related to Bluetooth being turned on. If I have Bluetooth enabled, my phone will not use WiFi even though it shows as connected. Because most applications prefer WiFi, they won't even fail back to cell data if they see the phone is connected to a wireless network.

Yes I backed up my phone last week and performed a factory reset. I had some issues restoring phone calls and messages but the phone and wifi worked fine for about a day then went back to performing the same way before the reset.

We definitely want to get this resolved for you asap. Sometimes, when a new software update is released it conflicts with the applications already downloaded on your phone. Have you recently backed up your device? NicholeK_VZWFollow us on Twitter @VZWSupportIf my response answered your question please click the �Correct Answer� button under my response.

StevenG, It was after the Marshmallow upgrade. I had numerous issues with lollipop but not this severe. The Airplane Mode trick does work - if I turn on Airplane mode with wifi, the connection works great. Any app or webpage works just fine. If I go back to regular mode, wifi works terrible.

Hojo_schreck, we know how important it is for all the features on your phone to work properly for you. Is your phone up to date with its software? Do yo have any network monitoring apps that can be removed?StevenG_VZWFollow us on Twitter @VZWSupportIf my response answered your question please click the �Correct Answer� button under my response.

I've been dealing with the same issue for 2 weeks now. Everyone at the Verizon store thinks it's my problem. I even got a new router from Comcast. Did a factory reset and it worked great for a day but then I had Bluetooth problems with my truck. Then last night it went back to doing the same thing. My smart tv plays videos faster than my phone at this point.

almsracing, wow, I did your suggestion and it has made a world of difference! Thank you! Any idea why this works or what the problem might be?

A few of my devices did that same thing, but stopped, and when MM wasintroduced just my G3 started again. I never put two and two together untilyou said it was preMM.On Mon, Feb 22, 2016, 11:32 AM almsracing

Just in case people are still having problems, I managed to solve mine - after doing everything mentioned in this post, I finally found this article: Android Marshmallow problems and how to fix them - AndroidPIT

I updated all my apps, then cleared app cache data.

Some old data from some apps was causing the issue. After dealing with this for a week, it is a breath of fresh air to have a strong wifi signal again!

Probably not the solution for everybody, but it worked for me!
