Since 6.0 my wifi is crap.

[chaz904]

I updated to 6.0 marshmallow a week or so ago and it completely destroyed my wifi. I am a cable installer so I hook up 3 or more modems/routers a day. My wifi just turns off and back on every 30 seconds or a minute. I know its not my router and it with every wifi I connect to. Any ideas? Im on TMobile. Also my battery life has went to hell.

Same here, Wi-Fi went to shit. Battery consumption as well, is noticeably different. I've been able to manage some of the battery with greenify and amplify but still not as good. On the bright side I don't have any more lag when scrolling through programs or through web pages et cetera so I'm happy there. I'm sure we'll see some marshmallow ROMs pop up over the next few months that may address some of these issues, that would be nice.

I turned off Wifi Scanning from Location>3 Dots>Scanning then forgot my WiFi connection and set a static IP Address and used Google DNS for my home Wifi then cleared all caches and it seemed to help some.

My understanding is that MM defaults to ipv6 and that's the problem. I wonder if setting up ipv6 on my Router will help more going to try that next.

Is this a bug everyone is having?

From what I read, yes.

In Developer Options I switched to use Legacy DHCP client and my Wifi is fast again. Battery is still draining fast but I'm going to reflash MM clean this weekend and see if that helps.

I have a metro pcs variant running a stock tmo variant's marshmallow.

I don't have the Wi-Fi issues.

Battery isn't improved. Maybe slightly worse. Nothing drastic. Its standby time is much better but when I'm actively using it for extensive periods I'm noticing the Battery seems to drain a bit more quickly than before.

From what I understand, Doze kicks in when the phone is completely motionless and hasn't been used in a while.

I'm going to try and test it this week and leave the phone on my desk at work unless I get a call or make a call or text.

My wifi is going out every 30 seconds. It is almost to the point where it is a disadvantage for me to use wifi because after it cuts out between the time it takes to switch over to 4g I have no service

Is this only at home or every wifi hotspot you go to?

le

Every Wifi. I install cable daily. I try and connect to the router to change passwords but it wont even stay on long enough to do that.

Fixed my wifi by flashing stock mm 10b stock rather than taking the ota update route that I did before. Wifi is back to being lightning fast again.

After flashing 20b wifi wouldn't turn on at all so I performed a factory reset and it kicked right on and is fast as it was in lp.
