This is probably the issue, please star it if you are also noticing this: https://code.google.com/p/android/issues/detail?id=96632
Whenever first disconnecting to a WiFi network (e.g. leaving a place), while the phone is "temporarily avoiding poor connection" (as seen in the WiFi settings page), mobile data doesn't kick in until it fully disconnects, resulting in the phone being disconnected from the internet until the WiFi signal gets stronger, or one gets far enough from the network for it to disconnect fully.

As far as I can tell it's a Lollipop issue.

I was reading an article about how the iPhone will automatically connect to WiFi instead of using the carrier network, when WiFi is available. As well, it manages the WiFi on the phone in a manner which minimizes battery usage.
Anyone know if any of the Android Phones do this?
Related to that, even if it doesn't automatically do that: If we are in a free WiFi spot that we know about and turn on WiFi, will the Android phone use the WiFi as prioritiy over the carrier network, thereby negating need to turn off access to the carrier network?

If you have 3g open, and you enter a wifi area, there are apps you can download which will immediately connect to that wifi spot without you opening Wifi, but those apps drain the battery and will connect at any wifi that you have previously used, thus becoming annoying. I tried it last year on my Android device.
It is much better to simply activate wifi alone, then it will connect to that free wifi spot alone IF you have previously connected to it.
I'll give two examples: At home when I connect my Android device to my wireless router for the first time, it will ask me for password. Then it saves it, so that if I close wifi, it will open 3g alone, but then if I re-open WIFI on my device, it will connect automatically as it saves the password of all wifi spots you have, and it shows you also the list of all saved spots.
The same thing goes for open free wifi spots, first time you connect to it normally without a password, second time it will re-connect alone as long as you have Wifi opened on your Android Device. I wouldn't have my cell to connect to any wifi alone without me opening wifi as it drains battery a lot.
As soon as you open Wifi, and there's an open wifi place or a private one (provided you have entered the password before), your cell will automatically connect to it and will no longer use carrier network until you shut off WIFI.
Thanks for the detailed reply. Much appreciated.
Actually, pretty much what I expected to hear.
Ran into some weird issues this weekend with my wifi connection with my focus.
The phone would randomly disconnect from my home network (strong signal, secured) and connect to an open network with weak signal. I would find this out as I would try to do something that required data and it would just hang and do nothing, I would have to go into settings and disconnect from the open network, reconnect to mine.
Frustrating that there was no way to force it to use our home network or to forget the other network and it stay forgotten.
Anyone had any similar issues. It was just this one day it did it, but was incredibly frustrating. I'm still within my 30 days, so if this is going to be an ongoing issue, I might should reurn the thing for something else.
It happened 4 times on my Note 3 in the last 10 days. I'm home or at work under wifi. Go out and try to use mobile data and I get an error message that I have no connection. Yet my LTE signal shows 50% and above in signal strength. I tried to turn on airplane mode to turn it off to force my phone to latch onto the closest cell tower and it's still doesn't fix the issue. If it happens while I try to upload some files, I check my email or try to browse the web and it confirms that I have no working connection to the web. I end up rebooting my phone and it fixes the issue. It's as if the phone is still looking for my wifi connection and "forgets" to switch to cellular connection once I leave the building. I know there is a setting under wifi that says to auto switch between wifi and mobile network but it doesn't seem to make a difference.
I'm running the official BTU 4.3 release on my I9505
I've noticed two issues with 4.3
a) Wifi
From time to time, perhaps daily, my phone loses connection to my home wifi. I get a notification which says something about being disconnected -- don't remember the full text. When I click on it I get taken to the list of wifi networks and underneath my local wifi network it will say "Sign-in is required".
It may be working as designed - checking my newish BT HomeHub 5 I can see the PPP session recycled twice overnight. Oddly this was initiated by upstream admin according to the logs, not a vdsl failure.... since the hub will intercept pages when ppp is down it's possible this caused the confusion
b) Security policy
I sometimes see a notification that an app required access to system, but didn't have permission - yet when I click on the notification I get taken to a full list of apps -- how do I find out which one was trying to be naughty?
The WiFi problem can be quite annoying.
I think this is not an improvement over the previous functionality.
The idea seems to be that as soon you have to manually log in to a WiFi network Android switches to the cellular connection to make sure you are always connected.
The thing is that at my work place this means every time I get somewhat out of range of WiFi (elevator, toilet, staircase) and walk into range my WiFi stays disconnected until I remember to reconnect it.
I only have to actually sign in once a day, but as Android thinks it is a network you have to sign in to it will not automatically reconnect to that network.
Meanwhile the phone is using up my data allowance....
So my problem is that after i connect in any wifi network, my phone says "no internet" however I really have internet connection (for example i can go to facebook), and after reboot it works normal sometime. Tried factory reset with no any help. So does someone have same problems and if you do, did you fix it?
My phone does this with any wifi network and everytime reboot "fix" it. Also i don't do anything special before this problem appears.
Phone: S7 Edge (G935F)
OS: Android 7 Nougat
so it's just cosmetic?
I guess to determine if you've internet the smartphone is pinging a certain server which seems not to be available in your case.
I only did restart once and while I'm on recognized network, it was fixed permanently. It happened only on first use, you may need to reboot the router

Okay, thanks for the info, i'll test that and see if it works for me.
EDIT: it didn't work for me

Well i guess it's only cosmetic since i can use browser normally and my whatsapp etc works great. I just don't understand why it works this way.
I have similar issues on my wi-fi. When strength of signal goes under 50% (ca <65 dBm), it starts to lag and very offen lost connection to the internet...pretty disturbing and dissapointing I have to say.

Okay, is it like it's really losing connection or just saying that like in my case (i have the connection, but my phone thinks i don't so it shows that "no internet" notification in wifi settings and in the wifi icon)?
It is really also losing of connection, download stuck or is really sloooow. It is also indicated in status bar in Wi-Fi icon (exclamation mark) and under Network name is "Internet can be unavailable".
When the signal is weak, I can't even finish network test through Ookla app - upload test can't be finished.
Same situation is with other wifi networks...in my work when the signal is at 50% signal, it keeps disconnecting and reconnecting, my other phone has stable connection at the same place where Edge is strugling
