Samsung Note 5 WiFi and Battery Drain Issues After Marshmallow Update (6.0.1)

Ever since I did the recommended Marshmallow update, 6.0.1, I cannot connect to any WiFi at any location. I even switched routers to determine if that was causing the problem. I have embedded a side by side comparison of a speed test between my Note 5 and Note 3. Technical details of setup are at the end of this post. Also I noticed a significant battery drain after the update. I did the update I believe this past Sunday, March 6.

Technical Specs of Network:

Equipment:
- Cisco WRVS4400N (latest firmware)
- Cisco RV180W (latest firmware)
Internet Speeds:
- Hardwired: 200+ Mbps download / 30+ Mbps Upload
- Wireless

Although I have unlimited data with WiFi in these locations I need to be able to maximize my speeds. Please advise on fix. I have tried to reboot phone, start in safe mode and throwing the Note 5 against the wall (haha, just kidding)

I am also having battery drain issues. Didn't even last 7 hours of idle time when fully charged!

Turn Bluetooth off and wifi will work again. I am having the same problem.

Thank you. That is a viable workaround. A problem associated with me and I'm sure others is I use a Fitbit and stream music to Bluetooth headphones. Fitbit uses Bluetooth to sync.

Another problem I found is that when the phone is on mute all alerts come through as if it is on normal sound. As always I've tried a reboot and safe mode.

Verizon and Samsung - ARE YOU WORKING ON THIS? I've been a loyal Verizon and Samsung client for years and have a corporate account. Don't change my mind.

who's you're internet provider??

fwiw:

my battery usage has been about 50% better after 6.0.1, doze works well.

I have Time Warner Cable. Hardwired speeds are 230+ Mbps down and 30+ Mbps up. As mentioned in an above reply I turned BT off and got 14 Mbps down and 23 Mbps up. My Note 3 performs 100x better.

I am running the latest Arris Motorola Modem SB 6183 I think Docsis 3.0, Cisco gigabit wireless router and all lines are over Cat 6.

I'm having the same problem since the update. But only on networks on 2.4ghz. If I connect to my 5ghz network it works great. Very frustrating while on the go. Hopefully an update will fix this.

I am having major battery drain issues since the update on my Note 5. I am hearing Samsung is working on an update to help fix both wi-fi and battery issue. One other issue I ran into is the power saving mode, its almost useless to yse the immediate function as it will not allow anything to sync. I need certain things to sync regardless and others not so much. They need to create a place where you can set exceptions.

bearone21

that's what power saving is all about, use as is but you don't get any options.

bogger44fl:

i don't do wi-fi unless it's encrypted, never public wi-fi.

I am experiencing the same issues. Wifi only works when connected to an AC channel. If I am just connecting to wireless n router I can not get any bandwidth. Tested and verified on 5 different networks.

Has anyone had issues with putting phone on vibrate and mute but still have sound come through? The only way for me to avoid this is to turn on DND. Another PITA.

xstreampros

Some other weird things I have found is when the phone is on do not disturb mode and I'm on a phone call and put on speaker it hangs up the call. Also in order to get the phone when set to vibrate and mute I have to turn notifications and system volumes all the way to mite manually through settings - sounds and then place in vibrate or mute mode. Otherwise they are full volume but grayed out when setting.

I have also had wifi issues since marshmallow 6.0.1. One poster is correct that wfi and bluetooth are not playing nice together. Wifi dies with Bluetooth on. Shut Bluetooth and wifi is fine. I wiped phone to factory twice and still the same issue. Wiped the cashe partition as i saw in other forums with no luck. Battery life is terribe now as well. maybe it has to do with these communication issues. I was hoping marshmallow would make batter life better with googler doze but it's worse. Verizon tech, is there a way to reload 5.0???? This device has become unusable.

alngater73

Yehh, Verizon we need something done here. I rely on my phone to not drop 2% battery in 1 minute!!! Basically carrying a brick at this point.

bearone21

how about before the update, you don't say but how many apps are you continually updating fb, twitter + any other media, stocks/bonds, email, nor whether you had problems before the update.

robveee:

doze works well for me, increasing batt life with the same use of the phone before the update.

Just adding a +1 as I am also experiencing the issue with my note 5 after the marshmallow update.

Both at home using an almond+ router (either the 2.4 or 5 ghz channels) and at work using a corporate cisco network. If I want to stream music to listen to on my bluetooth headphones or over my bluetooth stereo connection I have to disable wifi which is great for my date usage :smileysad:. Needs to be fixed immediately.

My wife and I have S5 galaxies. Both bought the same day. Both have BT dropouts with marshmallow. Mine had battery drain in 6.0.0, hers, not until 6.0.1. Mine is much improved in 6.0.1. Comparing the two, I went in the Battery control panel, and noticed, hers was running Cloud 27% of the time. Mine was not on. She doesn't use Cloud, so I went into application manager, and hit disable and Force Stop. It asked if I wanted to revert to the factory version, and I replied yes. Now her battery life is much improved, although we both run battery saver, as I will not connect with work wi-fi, as it filters too much content. Check your Battery Control Panel under Settings to see what is draining you!

I RESET MY NETWORK IN SETTINGS. THIS IS MY RESULT.......NOT MOBILE DATA
