I'm using my phone on ATT, in an area with pretty good LTE coverage. My bootloader is unlocked, and phone is rooted. Stock rom. I have one wireless network saved, which is my home network. I manually set this up when I got my Nexus 5, I did not import wifi settings from a backup. For the first few weeks, everything was fine. This is a relatively new problem I've noticed, maybe the past week or so.
My daily routine generally goes, leave for work in the morning, come home in the afternoon. I'll start my day connected to my home wifi. When I leave, most of the time it will connect to LTE. Maybe only 10 - 15% of the time, it will connect to HSPA, and just show the "H" icon, not LTE. If I'm stopped at a stop light, I can toggle airplane mode, and it will automatically connect to LTE, even though I'm in the same physical location and haven't moved. Along the way to work, which is about a 5 mile drive, I can notice it searching for wifi networks, picking them up all along the way. I can check the available wifi list, and see it updating. I get to work, and it will pick up the wifi networks there, which I do not connect to. It stays on LTE all day.
8 hours later when I leave work, wifi is no longer scanning for networks. Even if I go into my wifi options, and manually choose "Scan", it won't update the list. I'll go 5 miles home, and it'll still show the same work wifi networks with nearly full strength, despite being miles away. Hit "scan" again, and nothing. Doesn't refresh the list. If I try to connect to one of the far out of range work ones, it'll just switch to "saved". Toggle airplane mode, and it'll start scanning networks again, and automatically connect to my actual saved home network.
I've toggled all the settings in the advanced wifi options. I've tried the FXR WiFi Fix and Rescue app (https://play.google.com/store/apps/details?id=com.brilliapps.wifiandmorefixer), which deletes all my saved wifi settings and re-added it, still the same issue.

I saw several posts suggesting that leaving WiFi on where you have WiFi connection helps you to save the battery which I'm finding pretty strange. I thought WiFi actually drains battery faster then anything else. Are savings due to the fact that WiFi is more efficient then 3G or does it actually holds true that it saves battery?
All things being equal, Wi-Fi uses less power than 3G. Wi-Fi radio waves don't have to go as far, so they're easier to generate. When Wi-Fi is on, 3G is off, so you'll save power if you're actually transferring data.
A lot of programs will initiate data transfers by themselves when connected to Wi-Fi though, so perhaps that is why some will notice higher drain when Wi-Fi is on.
Also, if Wi-Fi is left on and you are on the move, your battery will drain since your phone is constantly searching for available networks.
Unless you've changed the settings, however, when your phone's screen it off it switches back to 3G to handle data.

This however, is untrue. At least for me. I run the leaked 2.2 and my WiFi is always on at home, my data connection is never active. I check this by dialing *3282# and hitting send.

When I have wifi switched on I lose around 5 to 10% an hour. With it off I lose 1 to 2%. I don't have anything set to sync differently via wifi. I only have a few apps that sync data and those are set to do so every 4 hours or so.
I have tried leaving it both on and off overnight to test this and every time I've left it off I woke up with a full battery. If I leave it on I have to charge again in the morning.
When I'm going out I turn wifi off so that my phone isn't constantly searching for signal.

In the Wi-Fi advanced settings (Hit Menu when in the normal wi-fi settings), there is a Wi-Fi Sleep Policy (which specifies when to switch from Wi-Fi to mobile data)
By default, my device was set to 'When screen turns off'. the other options were 'Never when plugged in' or 'Never', I switched mine to 'Never'. You should notice that when you turn your screen on, the wifi icon doesn't show up right away. Of course, I'm on 2.1, so this may be different in 2.2, but check it out.
For me, I get no cell signal in the building at work so I need to keep wifi on. If I turn it off my battery drains fast from the 3g radio constantly trying to lock on a signal.
It depends in the quality of your 3G connection, but all things equal I have seen that using WiFi instead of 3G does save battery, when the WiFi is connected of course. Anytime a radio is constantly searching for a signal or trying to hold a weak signal, power usage tends to go up.

Check out Y5 Battery Saver.
This app turns your wifi on/off based on the cell towers that you are on. You just connect to wifi, enable the app, and it remembers what cell towers you were on while you were in range of that wifi location. as soon as you are off of those towers, it turns off wifi. to add new wifi locations, just disable the app, connect to the hot spot, and re-enable the app.
This gives you the best of both worlds. you get to save battery while you are using wifi and when you are out of range it doesn't continually search for new wifi networks to connect to.

Whenever I turn my screen on, my wifi icon is right there. No delay in it showing up. I don't remember ever changing the sleep policy when I updated so I believe this is the default behavior for 2.2

+1 on Y5. There are a few other apps in the market that claim to do the same thing, but I think Y5 is by far the easiest to set up and works really well. Nice little utility so you don't have to keep remembering to turn off the wifi manually when you are out of range.
Now if I could just find a app that does the same for my bluetooth when it is near my car....but that I think is much harder to do without it actually polling.
I have been using tasker on my tablet for about 2 years now, and all of a sudden, for the last week or two, it has been acting differently. I have a tablet installed in the dash of my car and use tasker to turn off all radios (mobile network, wifi, bluetooth, etc..), turn off the screen, etc.. when the car turns off (no power), and then turn all of that stuff back on when the car starts (power). The problem is that all of a sudden, after a couple of on/offs of the car, if I use the airplane mode on/off, it gets stuck and I have to restart the device (basically, in the notification panel settings, the airplane mode is half lit up, like it is in the process of turning off/on). If I use the mobile network on/off, it will show that it is picking up the network, but I cannot connect to the internet (shows the bars are full, for instance, like it detects the network, but I can't access any data). Also, to go along with these two things, I used to, when leaving my car parked overnight, come back to maybe a couple percent loss of battery life... now, it is dropping significantly (probably 30+% or so each night).
Anyway, I have been searching around online for a while now and I cannot seem to find an answer anywhere. I installed a new SIM card from Verizon, have factory reset it, and nothing works. If I disable the cell data disconnect (either mobile network or airplane mode), when I come back, it shows the signal bars with a small "x" in it and no connection. Either way, only a restart fixes the connection.
Attached is a screenshot of my devices info if that helps as well as a picture of what the "half stuck" airplane mode looks like.
Any help/info is greatly appreciated... thank you!

Sometimes my WiFi goes away, LTE kicks in for a second, and then WiFi comes right back. I don't know for certain, but it may only happen when the phone has been unused for a while, right after I first pick it up to do something. But I have the WiFi power saving option turned off, so that WiFi should stay on all the time. And I seem to recall it happening just at random sometimes, too, in the middle of browsing websites or social media apps. It'll say "no connection" and I'll look up and see LTE kick in, then WiFi come right back, then I'm all good. It's very annoying.
On top of the quick WiFi cycling issue, sometimes WiFi will just completely stop working. When I go into settings, it says it's disabled and I can't turn it back on. Going in and out of airplane mode fixes it. This only happens about once a week or so. The other issue is by far more annoying.
Anyone else experiencing either of these? I'm on Verizon with a black 128 GB stock, unrooted, if it makes a difference.
Thanks!
I personally haven't seen this on my VZW Pixel although I use it with T-Mobile service. These are as suggestions only, and it may or may not help, but you could try using any order below.
1) The setting to keep WiFi during sleep is on, right?
2) Have you tried to use your phone without sim card in it and see if WiFi is still acting strange?
3) I would also suggest to go to Settings>Google>Networking and see if you have WiFi assistant on or off. There is a setting under advanced as well.
4) Does it happen on all WiFi networks or when using on particular one? You could forget that network and then join again.
5) Alternatively you could "Network settings reset" under Settings>More>Network Settings Reset - after the reset, you may need to rejoin all the networks, pair Bluetooth devices and so on.
Got a new S8+ yesterday.
Everything is fine except WIFI, it keeps disconnecting all the time, going on and off, until it finally stops working...
I tried removing all background signal checking and all unnecessary options, and also I did reset it to factory twice, but the problem persisted...
I have my former S7 Edge on the same network without problems...
I am having the same issue. Disconnect then reconnect every few min.
I had one disconnect this morning but it transfered to the 2G instead of the 5G.

Check your network settings; it may be switching between LTE and WiFi to "conserve energy, buy having the strongest connection." I have had that issue in the past with other devices.

Tried that already, but it is completely disabled..
In fact
Nearby Device Scanning is OFF
Wifi Calling is OFF
Location is PHONE ONLY
Smart Network Switch is OFF
Network Notification is OFF
Hotspot 2.0 is OFF
Keep WIFI on during sleep ALWAYS
and it is still happening.....
When I was first provisioning the device at home I was running it off a Ubiquiti AP Pro and kept getting disconnected. I took it off WiFi and ran the setup on 4G LTE only and connected to my WiFi after. I run Google Fiber and did some 5GHZ speedtest and was never less than 600mpbs up and down. Absolutely 0 chance the initial issue is my network at home. I haven't seen it disconnect since the initial setup but that does worry me a bit. I'd wipe the network profile and set back up.
Probably unrelated but I've found that the 5Ghz WIFI strength on my S8 5.8inch is terrible. The 2.4Ghz is fine though. Compared to my Pixel the 5Ghz is on average about 1/3 the connection speed at same range as the pixel and has much lower strength signal (testing with WIFIAnalyzer). If I cup the phone with 2 hands in landscape mode (how I normally watch videos) I often lose my WIFI connection completely from the 5Ghz network here.
Me to having same issue with WiFi disconnect automatically getting irritated from that
How to fix this guys
Had the same problem on mine. Setting the IP address to a Static IP fixed the issue.
Try going to settings, backup and reset, reset network settings. See if that works.

I've had an S7 for a couple of months now and I am having issues with it switching to known WiFi networks, especially at home.
When I return home it just doesn't switch to WiFi automatically. My wife's S7 does. So I copied her WiFi settings, and it still doesn't switch back to WiFi. I have smart network switch off and I've tried with it on. No luck.
I thought it might be my router, the Sky Hub, but we changed to virgin media at the weekend. And it's made no difference. It's like it isn't scanning for WiFi networks, when I look it doesn't show mine until I turn WiFi off and on again on my phone. I've searched Google but can't find an answer.
Does anyone have any suggestions? It's annoying me now.
