wifi problems after Android M update

[tonyvr4]

I have an LG G3 (AT&T D850) and after the Android M update I am having problems with it not connecting to wifi. I found a trick by turning on AIrplane mode, turning on wifi then turning off airplane mode. It helps but it is annoying to do it every time the phone will not connect.

Anyone know of a more permanent solution?

Have you already tried rebooting your router by unplugging its power for 10 seconds, then plugging back in? Does this problem happen on any wi-fi network, or just home?

I have tried rebooting the router. My other devices or computers work done.

And it is not limited to one wifi location. It happens anywhere and the problem only started after Android 6

That's weird because after the update my G3 is even better than before

Does this persist in Safe Mode? https://support.t-mobile.com/docs/DOC-11934

I found the problem. It was AT&T Smart Wifi. I disabled the app and now wifi works fine. No dropouts or anything.

I am having a battery problem which I will post in another thread

Glad you found the problem! Not very smart Smart Wi-fi app, huh? These kinds of manufacturer- or carrier-specific "optimizer" apps often cause more problems than they try to solve ...

You are right. I found another setting in the Qslide called "Battery Saver"
I don't know what it is supposed to do, but it should have been called "Battery Waster"

The battery time was horrible with it on, even with everything turned off.

I suddenly had Wi-Fi not working properly. This after hard reset because my SD card is dis mounting. Anyway, i switched into airplane mode and also disabled "smart" Wi-Fi. I was able to connect to my home Wi-Fi again.
