WI-FI Sleeping? - Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe

This is a problem I've noticed for quite a few months now, before the MIUI 12 update (possibly even saw it on 10).
The best way I can desribe it is the WI-FI connection seems to go to sleep randomly when the phone has been locked.
I won't get any notifications, I won't get any messages through facebook come through etc. The device still says it's connected to my home WI-FI network though. If I try to browse the web or do something else then it will try to do it instead of saying No Internet, it acts like it does have an internet connection (probably because it believes it's connected to a wi-fi network?) but will never succeed.
If I then turn WI-FI off and on again I'll then get bombarded with notifications and messages I've missed.
Is anybody else experiencing this and is there a solution? It's only a 2-second inconvenience to flick the WI-FI off and on, but it's an annoyingly regular occurence and more importantly I'm missing messages and notifications which could be important to me.

Gray bars and Green bars? What in the world?

My friend and I both have N1's there are times that his radio bars are green and sometimes gray. I have not seen this with mine yet (just got it today). I only have seen gray. What would these color differences indicate?

yeah green = connected to google servers.
grey = disconnected from google servers.
Thanks Guys
Wanted to bump this. I am having this same issue, and my bars go from green to white especially after unlocking from standby. When they are white, I can't connect to anything even though I am connected to wifi at home? This issue is REALLY annoying. Anyone else dealing with this or know of a fix? Sometimes it randomly changes while I am using it. The only way to get it to go back to green is signing into google talk, which sometimes takes 3-4 tries with server connection errors in between. When I am at home I have little to no internet connection via cell, and gprs is all I can connect to, which is why I use the wifi at home. I just don't understand why I can't use the internet if the google server is not connected, and why it drops the google server connection constantly. I should be able to use wifi for browsing apps even if its not connected to google???? Or am I wrong. Please help.
Thanks
(I am running stock, and the phone is not rooted btw..thanks)

try changing your wifi sleep policy to never...
settings--> wifi or whatever--> press menu --> sleep policy --> never
that SHOULD fix it when you're at home... outside i don't know since i dont use data.
cheers!
You're mixing cause and outcome. Your WiFi doesn't work at home, or your phone doesn't want to work with your home WiFi - that's the reason you can't connect to internet, and that's also the reason why you're seeing grey bars.
I have started having this problem this week too. My WiFi is fine. The browser connects and loads pages fine. My connections are now always grey/white instead of green regardless if I'm on WiFi or 3G/2G. All Google services do not work. I am not receiving push emails nor can I force sync in the Gmail app. I've tried to connect by opening up Google Talk but it closes right away. My WiFi sleep policy is already set to never.
My phone is running stock 2.3.4, unrooted.

[Q] No switching to data when wifi signal weak

Here's a classic problem I've been having:
I have wifi enabled at home, and it works great. I walk out to my car parked on the street, and from here my phone still sees my wifi network, but it has a very weak connection and basically can't transmit any data. I open Google Navigation to get directions to drive somewhere, and the phone just sits there trying to find directions, or connect to server, etc.
It would seem that whenever my phone can find a weak or public wifi (which requires a login-screen and does not actually "connect" to the internet), then I essentially get no data connection whatsoever. Isn't there supposed to be a function in the phone that will automatically switch over to 3G or whatever data network is available to fill in the gaps?
This is really annoying me, as Minneapolis has public wifi everywhere, which my phone thinks is "connected" when its really not, so basically its a coin flip as to whether my data connection will work when I'm driving.
Try turning off Wi-Fi?
Of course, I do turn off wifi and the problem is gone, but I seldom remember to do it on my first time. It's most apparent and annoying when I do a voice command or voice search while driving, and then it says "connection error" and I feel like chucking my phone out the window.
If I had true 4G and an unlimited data plan, I'd probably never even bother with toggling wifi on, but as it stands now, with a 200MB plan, I really need to keep wifi on whenever possible.
Is this a common occurrence with Captivate, or Android in general? I ask because this issue just came up yesterday, and I just got owned by an iPhone4 user. We both wondered if it was going to rain soon, so we both opened our browsers, and I was stuck looking at this stupid public wifi login screen, and was putzing around with wifi, when BAM, he just shows me his iPhone with fully loaded weather radar, etc. Hence I wanted to get this issue resolved now more than ever.
Not sure if the phone has this setting but windows 7 has an option to turn auto connect to open wifi spots off. So you gave to manually connect.

Unable to connect pop up

I've been getting a pop up window appearing pretty often that's getting very annoying now saying that it's unable to connect with pictures that show a phone a wifi signal then a red ! and then a globe with troubleshooting , cancel or retry buttons!
But I am connected and have good signal, anybody know what's going on?
Also, and I don't know if this is linked, but recently when I connect to my wifi, my phones data rate is either really good (as it should be 3ft away from router) speed check around 25mbps d/l 12 u/l or extremely poor lucky if speedtest app shows over 1mbps!!!
I've done all the usual things, reset router, checked settings, reboot phone etc, etc, any ideas?
Thank you!
Running stock 4.3
Happens for me too!
Me too, only after the 4.3 / 5.5 update.
Wi-Fi is connected at 72Mbps, just getting that annoying popup.

Moto G (Dual Sim) Internet Connectivity Issues

Hi, I'm new here so forgive me if I do something wrong^^
First of all, I have a Moto G 2014, Dual Sim which is running on 5.1.1, to be more specific, this ROM. I was using this ROM for about 4 months already so that shouldn't be the issue. My problem is that after my phone connects to the internet, usually using H+. The connection to the internet is working perfectly fine, but after a while of not using the phone it loses the connection. It still tells me that it got a strong H+ connection, but nothing (browser, apps, anything) is able to connect to the internet. Enabling & disabling airplane mode usually fixes the problem. From time to time it also happens, usually when I lost some sort of wifi connection (regardless if I disabled wifi or I got out of range) it happens that it shows full connectivity but with an exclamation mark. This only goes away if I reboot or enable & disable airplane mode again.
Is this issue known/is there any solution to
I have been experiencing the exact same thing as of lately. I thought it was a byproduct of downgrading from (Stock) Marshmallow to (Stock) Lollipop (yes! it's happening even on stock ROM) where at times the WiFi losses connectivity when the phone had been sleeping for awhile...even though I have the "Keep WiFi on during sleep" option on under WiFi's advanced settings. I had no idea that it also happens with data connections ! ...as I don't use it (too expensive for me), now I'm uncertain what could be the cause. I can see how this would be an inconvenience if you use a lot of social media apps as I sometimes do not get my WhatsApp messages when this happens and sometimes I don't even receive my Hangouts messages until I open the app manually.
It's strange, at times when my phone sleeps for awhile and it losses connectivity and I wake it, it will reconnect just fine and other times it just goes into this state where it reconnects with full signal strength but with an exclamation mark next to the WiFi icon in the notification bar. When this happens, no matter what I try it stays in this state, I tried turning off WiFi and turning it back on, also forgetting the network and entering the info and reconnecting to it but none of that works. I didn't know that turning on and off airplane mode can help....I'll have to try that one, rebooting the phone was the only solution I found which is just inconvenient and somewhat annoying.
I too, am interested in a proper solution. I don't know why the phone ignores the "Keep WiFi on during sleep" option or why at times it connects but have not internet access! It should be noted that it's not a problem with the network, It's not due to an incorrect password or anything like that as I am the one that administers those things and when it happens other WiFi devices such as my Tablet PC, Laptop etc can connect and access the internet just fine and it only happens sometimes on the phone (Moto G 2014). This doesn't seem to happen in Marshmallow...but I hate Marshmallow and I can't remember having this issue on Lollipop post Marshmallow update (how I wish I had never tried out Marshmallow!!!), which is why I thought it was related to downgrading, .......did you downgrade ?

Delayed notifications over Wi-Fi

I am having issues with receiving notifications on time over Wi-Fi after screen was turned off for 10+ minutes. Usual delay is about 5 - 10 minutes. I don't have any problems with same applications and scenarios over mobile connection. These apps are chat and video call apps: WhatsApp, Viber, Duo, Slack. This is especially annoying for calls, because I just get missed call notification (after 5 or so minutes or if I manually launch the app), instead of a call ring. I ticked all of them off in "Optimise battery usage" section. Same behavior on Oreo and now on Pie version. Same behavior on my home network, my parents' house network and at my work place. Browsing, streaming and all other things over internet work, no issues with it, so the connections were good. I have SMN960F model, if that matters.
At first, I thought this issues are caused by Doze when the phone is in "Connected to Wi-Fi" state. I don't even know if Doze could distinguish those two states (Connected to Wi-Fi or Connected to Mobile). But since everything works just fine over mobile, I doubt it is Doze. Now I think it is something related to my Wi-Fi settings, but I can't figure it out.
@Japro
Did you ever figure this out?
