Hello,
I've used my Mi A2 around 2 weeks now and I'm really satisfied with the phone. However, I got some annoying issue about wifi. When the signal strength of wifi is not so strong (below -70 dbm), it tends to disconnect for around 10-20 sec and then reconnected again. This happened to me like 10 times since I got the phone. And wifi works perfectly without disconnections when the signal strength is strong enough.
Does anyone experience this issue? Or I got a defected device?
Thank you
Same here, sometimes it just disconnects ...

It is a normal stock android behavior, because android detects that signal of wi-fi is to low, and tries to switch automatically to GSM mobile data, or to another wi-fi if it is available in the area.
I don't have this happen but wifi signal is strong and also; gsm data is turned off.
That *may* help to turn that off possibly, as it obviously can't (now) switch to it?

Even if mobile network is off? Is there a way to change such behavior? I tried to find in the setting but what I just found is Aggressive WiFi to mobile handover, which was already turned off.

I think that it is called smart wifi, or wifi+ option in other types of android OS, and here it is just a automatic option in stock android i guess.
I don't mind it, because it will change my wifi router AP if it get stuck, and need an reboot, so it will automatically switch to another closest one that works.
You better think of some way to get a better signal then to turn off this function.
Try with aps like this on the link.

The thing is that wifi also disconnected when there's no other nearby networks to switch to. I did something to get better signal in my room but this still happened sometimes.

What is the rom that you use? Did you do clean flash? Did you flash any kernel? Did you try to forget the network and reconnect again? More information is needed.

i'm using the stock ROM but i did unlock and root. i am using a asus RT-N56U with WPA2 personal AES encryption for security. Phone set for best wifi performance, wi-fi band on auto, keep wi-fi on during sleep.
I can connect and it will work usually especially if i turn off wifi then turn it back on. However, the problem exists that the length of time the connection will remain with the ability for loading webpages/video is unknown. It could be 2-5 minutes, but i've also tested it and its been able to hold a connection while constantly streaming a netflix movie.
I'm wondering if it could be resolved by setting my phone to connect to my home network via a static ip? seen things related to that elsewhere. It is very annoying and troublesome to have to constantly turn on/off the wifi when im sitting in the same place. I could be reading a webpage then click a link on it and then it will fail to load even though showing i am connected. Then i have to switch on and off. This has happened plenty of times within 30 minutes i've had to turn it on and off 3-4 times. To me that is not "functional".
is it something with my phone or router? or both?

you definitely shouldnt have to connect with a static. it may help but what about when u r in public do you still have the problem?? if not then maybe u should try a new home networking device or play around with the security setting on ur router.
my wifi seems to work fine other than my speedtest results are only 3mbps up. i should be getting as much as 55, i used to get up to 40 on my gs3. i am totally stock, with the same settings.

Do you have sleep mode turned on, in settings, power? Or power saver?

Maybe try unplugging both your modem and router for 10 seconds and then plug them back in.

So I am using a Nexus 6 on the Latest Tmo build (28E?) of Stock Rom and Stock Kernel Rooted, Encrypted.
Since the update that enabled wifi-calling for the N6 I have taken to setting my phone to airplane mode and turning on Wifi only to save battery since the signal at my house bounces back and forth from LTE to 3G and that murders my battery. Most of the time the signal strength graph shows blank and battery app correctly shows the cellular radios as having no on time. However, after being idle for a while (it would seem) the graph begins to show the signal strength as Red (no signal) and the cellular standby shows up in battery usage with the radios as being on (with no signal) and "active for a few seconds". Toggling airplane mode on and off usually restores them to showing up as off. Other times I never notice and it stays on for a few hours and goes back off on it's own. My main concern is that it seems to be activating the radio on it's own, my minor concern would be that my battery monitor app shows that it's using the battery. What could be causing this? I don't think it's a reporting glitch, because it shows up in both the system battery panel and a 3rd party one. If anyone has any thoughts or could point me towards a tool that could help me figure out what's turning on the radio when it's supposed to be off, please let me know. I've included photos from today showing what I'm talking about, the phone has been in airplane mode the whole time in these photos.
Thanks so much!
Kev
I think your issue is one of the reason why I cannot get Wifi Calling working at all. No matter what I do, my phone is holding onto a cellular network. Still trying to figure this out.

The best I can tell, "Android OS" is the only thing that shows any mobile packets sent or received so it's got to be a system thing.
If you have the myT-mobile app installed try uninstalling it I found that app totally screwed with my Nexus 6, turning WiFi on when I had no desire to use it.

Unfortunately that's not the fix. I don't have that app installed. Tmo is sending me a new SIM as I am also randomly having Wifi calling drop in and out even while my wifi is connected.
Does anyone know any app that would let me see specifically what app is engaging the mobile radio?

... I just joined to see why is my Nexus 6 receiving calls in airplane mode (and Wifi off...). It's a recurrent problem... everytime there's an update I have this issue...
I have it enabled and it says it auto turns off WiFi and back on when near used wifi locations but it doesn't do that at all. Does it simplyeave WiFi on but low energy?

Yeah it works.
How do you know it doesn't do it? Cellular phones hand off betwixt cellular and wifi all the time.
When and how often it does is based on some under the hood shenanigans that we dont know about.

I don't think it's supposed to turn off. What that phrase means is that it will connect to WiFi when it's near a saved access point and will use mobile data when none are nearby, but WiFi will still remain on.
What adaptive WiFi does is it will use mobile data even if it's connected to a WiFi access point if the WiFi signal is bad.
I'm not sure what adaptive wifi supposed to do, I have it off and it switches between wifi and cell as it should. Is it switching in the middle of data transfer or something? Because right now I probably drop connection if move outside wifi range and will be on cell tower on the next redial. But to tell truth I never tested it.
So basically it's a gimmick, because Wifi as it is, will auto-connect to previously connected networks as long as you had wifi on. If i'm interpreting the screenshot properly the feature "turns on" wifi, therefore, it must be able to turn it off? I've even manually turned it off to see if it will turn itself back on when i get back home and nothing either.
No documentation on Samsung's site as far as i can find

Basically if you're connected to WiFi but have crappy signal like .2 kbps, it will start using your mobile data even if you're still connected to that WiFi. With adaptive WiFi turned off, it will keep using the crappy WiFi connection until you manually turn WiFi off or manually disconnect from the crappy network. Pretty much the reverse of WiFi calling (use WiFi if phone signal is crappy). Note the exceptions sentence at the bottom, it will not use mobile data even if the WiFi has a crappy signal if the crappy WiFi is exempted.
The "turn on" statement is correct, it will automatically turn on and connect to WiFi when it's in range of "trusted" access points (similar to "trusted devices" and "trusted places") but there is no automatic "turn off", at least, it hasn't done that while I've been using it.
OK i see what you are saying
wifi does not PHYSICALLY TURN OFF. wifi is still connected--the phone will auto switch to the stronger of the two. it won't turn the on screen "switch" off if that is what you are looking for.
its not a gimmick. it works if you are in an area with robust wifi and/or cellular. its supposed to work "in the background" so you don't know its going on.
google fi kinda does this. since google fi uses tmobile and sprint, the phone auto switches between the two carriers depending on which is stronger at the time. i've seen this happen by monitoring an app.

Not a gimmick at all. I work at a hospital that has wireless routers throughout that all piggy back the same access point. I see Adaptive wifi in action all day. Keeps me from losing my connectivity from my work portal.
don't think I want to have this on: I have limit on my cell data, let's say I start downloading something large, let's say 5- 10 GB movie from Amazon on wifi, then I go to my upstairs bedroom, wifi gets weaker, so it switches itself to stronger cell tower and eats my whole month data allotment in one evening, before I even notice? And all I had to do is keep the phone downstairs, next to the router to avoid it. Or am I missing something?

Exactly what happens to me when I leave home. My phone (old Note 7) will stay connected to my home network but won't be able to pull down any data from the net. It has to be manually turned off.

Any 3rd party apps you can recommend that would do what i am looking for?
so an update. It work exactly how it says it would. I had to drive 7 miles out, but wifi automatically turned off, even with scanning off, once i got home it turned back on.

Ah, that's the thing. I noticed my WiFi would automatically turn off sometimes and sometimes not, and I couldn't reproduce it reliably. It's most likely either distance or time you have to be away from the "trusted" access point.
Congrats, now you can forget about toggling WiFi forever!
I think this setting has been screwing with my wifi related Tasker profiles. Suspect it really does turn wifi off.
I used to switch my wifi off manually when leaving the house.
All this #[email protected]\%! public wifi, blocking my internet because asking to log in....
Any shop or restaurant where you walk in does it.
And you do not know it, till you search the web and see that there is no internet at all till you switch your wifi off or log in to the shops fishing routers.
Adaptive wifi is a must have and a great improvement.
E.g. walk in a MacDonald's with adaptive switched on or off, you will see it is mother's little helper.
You need to have enough data from your provider of course.

Now that is some sweet use of the English language!
Im turn WiFi every time ON per Wifi disonnect or lose intensity. Im turn ON screen and WiFi connect/intensity up
Settings - WiFi - Settings icon - Wi-Fi always ON during sleepmode: ALWAYS.
PD: Sorry my bad english
¿solutions?
PD: use b156 patch1
EDIT:
I think I have found the problem. Wi-Fi+ activated. Turn OFF
No. Huawei has completely buggered the wifi implementation. It is easily the worst I have ever seen on a modern phone.
I have access to conformance test equipment as part of my daily work and so I have tested some more difficult to pass test cases.
The P20 pro fails nearly all wifi alliance handover tests that I have checked.
For example, when you are on a cellular connection and then you access a wifi network which requires a login, like at an airport or McDonalds, the cellular connection must be kept until a data connection via wifi can be positively initiated.
The P20 does not wait. You can see that it performed a PDP context deactivation on the cell side and trys to use only wifi. Fail
I have the same issue. WiFi is set to not sleep with screen off, but if I'm streaming from my Plex server over WiFi, it always cuts out after a couple of minutes after the screen being off.
What do you mean by "Wifi+ activated"? Where do you turn that off?
I have the same problem and it really sucks.

The only solution is to get a different phone. Huawei has completely F'ed up Android with their EMUI nonsense.
I have this strange issue that has been with me almost since the beginning. I haven't been able to trace when it happens, but it now seems almost 100% of the time.
I only have WiFi in the house (wifi6, if it matters). If I go out, I only have 4G (I left only 4G and disabled 5G). I have no data until I put the phone into airplane mode and back, or I disable and re-enable mobile data.
Same thing when I go back in the house: no data until I disable and re-enable WiFi.
I've disabled the option for 'always-on mobile data' or similar, it's quite a battery drain if there's no cell signal.
Seems like a very strange bug, I don't have this with any of my other phones.
So you have both WiFi and 4G enabled and they don't switch seamlessly?
Exactly. I always have to restart each one of them, usually by toggling airplane mode. Was wondering if anyone else ran into this issue.
Ok this really is strange. There are 2(!) different toggles to enable data switching between WiFi and 4G, but for me it works flawlessly without them! As soon as I get out of my home WiFi range, 4G kicks in, and when I get in range again, the phone connects to my WiFi...
Hi, i have this problem too but it's not always.
I have a wifi 6 router too.
I also have problems switching from wifi to 4g. Need to toggle airplane mode on/off. 5g deactivated. No wifi 6 here.
I always assumed my vpn is causing problems during the switch to 4g. But hearing others have the same problem i would assume its zenfone problem.
I never had any issues in this area with my ZF8. With the option to have cellular always on I could walk out of my WiFi zone during a video call and no drop or short pause would appear.
With this off the network need a few second to work, and some apps need to be refreshed/restarted to gain connection. Never needed to toggle connection for this to work.
Maybe a reset would be enough or check for updates.
Ah, exactly! It does not necesarily need a network restart, but some apps just lose connection for a while, which can be from a few seconds to >1h. Which is even more weird as the icons are showing full connectivity. I would go out of the house, do stuff, come back later and I would only get the notifications when I'm back inside the house.
Rarely I had the connection drop completely (no signal) when switching, but I haven't noticed this happening since the last update.
