[Q] [MIUI] Internet goes off when phone is locked

Hi,
I'm currently using miui 1.10.21 from miui.nl and ilstone's iphone theme,
when my phone is locked i notice there is no internet connection, and when i unlock it then the internet connection icon pops-up and there is a connection, sometimes when locking my phone the internet connection stays connected longer than other times. I want it to be connected to the internet all the time for things as e-mail pushing and messages from whatsapp..
How can i fix this?

By internet connection do you mean "3G/HSDPA/EDGE" or do you mean WIFI?
If Wifi there is an option under wifi connection to set Sleep Policy. Set it to "Never".
Just make sure to toggle it off then when your not using it, if indeed you are referring to wifi. Will cause extra battery drain if it's always searching. If your talking about 2g/3g there are apps that will shut data off when screen is off, perhaps you have one doing that without realizing it.

Galaxy Note 5 N920W8- Wifi Cuts In And Out

Wicked wakelocks and WiFi issues
Just yesterday I started having wicked WiFi issues, where both 5GHz and 2.4GHz networks would connect, then immediately disconnect, then connect again a few seconds later for it to just do the same thing, over and over. It keeps sending reports everytime it does it. I haven't factory reset though, but I'm going to have to.
Also, I keep getting insane wakelocks. Android OS is the worst, causing 7h+ of wakelocks in a 10h day. Google Play Services is pretty bad too, around 6h+ in that same 10h day.
Anyone else having major issues like this with their Note5? I have the N920W8 model, which I can't really find any info about anywhere
Im having similar wifi issues. Initially trying to connect to my 5ghz N home network (wpa2 psk) connect attempt, drop, connect attempt drop rinse and repeat. After a while it connects and stays connected, however, connecting to any web pages is painfully slow (like a super slow dns lookup), and i frequently get failed web page loading errors or failed to download apps from teh app store. Wifi calling is useless in this state. The same thing happens on an open hotspot network at work (2.4ghz) and the corporate (5ghz n) network. The note will ususally eventually drop wireless and force me back onto LTE. I looked at my data counter after just 3 days, and had used 27gigs of LTE, which is more data than I've used on tmobiles network since last year. Had some spotty wireless issues with teh note 4 rev 3 5.1.1 as well prior, but only had that phone for about 10 days before swapping for teh note 5. Prior to that I had the nexus 6 and no wireless issues on the same networks.
J'ai le même problème avec le 5g damn!!!
Luckily i have a dual dualband router, I set up the alternate AP 2.4ghz N wpa2 psk and the phone appears to be working fine at the moment on that network.
I ended up factory resetting and it appears working for now. A static IP address (DHCP reserved in the router) seemed to help.
Another issue I have though is when disconnecting from WiFi and connecting to mobile data, it seems to have DNS resolution issues until I turn data off and then back on. Not sure if it's the phone or the carrier (Wind Mobile) but it's pretty consistent
Not seeing these issues on my W8.

I'm just having dreadfully slow WiFi on my att model, but it doesn't drop connection
Dial *#0011# and click "wifi settings" from the menu at the top right corner. Turn off power saving mode and restart the phone, see if that does the trick.
If not, google search "note 3 wifi issues" and/or "note 4 wifi issues"and look for answers there. In all likelihood the problems that are being experienced with Wi-Fi on the note 5 are similar to the Wi-Fi issues that the predecessors experience when they launched.

It's Lollipop. It's a known bug in the software since Nov 2014 and Google hasn't addressed it. I too had issues with my WiFi when I first purchased it. But I found the work around. The bug is in the security software. The WpA2-PSK with TKIPS or AES which is a catch all, reeks havoc on our WiFi chips. It doesn't allow the phone to have proper DNS addresses resulting in severely slow internet or dropped connections.
Solution: Change your security standard to WPA/WPA2-PSK without AES or TKIPS.

Is that a phone setting or a router setting?
Hey guys,
I've got an Australian Samsung note 5 that has wifi problems. It started not working all of a sudden so i decided to go along with it but after a while i felt the need to try and make it work again. So i went into recovery mode and factory resetted (thinking that it would help) but then on the boot up after i came to the setup screen and found out that i was screwed. The samsung setup screen doesnt let you go past the setup screen without any wifi. Please help, i wanted to post a thread but im new to this community so i am restricted.
Thanks
p.s wifi networks can be detected but only when the phone is held right next to the router.
I fixed same problem of wifi, its a setting in phone, but you need to root phone, its system setting in system folder.
Any updates on this? Im running one 920g completely stock and another 920g with hybrid n7 port v9. Both have this same issue.

How to make wifi stay on while the phone is in standby?

I have 2 phones:
nexus 5 running lineageos 7.1.1
zenfone 2 running android 5 (asus stock)
Both phones after going in standby they drop wifi connection. and by drop i mean it stops working but if i wake up the phone there is no sign of searching network or anything that suggest its searching for network.
i know this because im using whatapp web and it says phone disconnected. and for more than 20 minutes...i got tired of waiting for connection
After i start to use the phones again, the web whatsapp resume its functions.
This does not happen if i use only 4G and disable wifi. not even when phone goes in standby.
Is there any way to make wifi stay on even after phone goes in standby.
Ive already marked the wifi connection to be always on. zenphone 2 "power saving" mode is put to performance also.
so is there anything else that i can do to fix this? both phones are rooted.
i guess nobody has any kind of clue

My note 9 seems to be killing my home wifi network.

I have several different devices connected to my wifi and dont have any issues. When I connect my Note 9 to the network it initially works fine. After being connected for a while my internet seems to go down. My phone shows that I am still connected to the network but says internet may not be available. All the other devices in my home lose internet connection as well. I can't get back on to the internet until I power cycle my router. Sometimes it will happen immediately after connecting my phone and sometimes everything will work for a while before going down. It has never happened when the wifi on my Note 9 is off. It's pretty frustrating and I haven't been able to find solutions. Anyone got any ideas or had a similar experience?

Sometimes, the router's memory becomes full and needs flushing in order to work properly.
If the router needs rebooting often or you find yourself unplugging your modem every few days, you might need to request a new modem from your ISP ( if they provided it ) or purchase a new router.

Redmi note 9 wifi glitch

My redmi note 9 is on miui v12.0.6.0 QJOINXM (Indian version). The wifi router in my house supports 2.4GHz/5GHz dual band. My phone often disconnects from wifi. It is like the phone is showing connected to wifi but there is no upload or download speed. I have to turn off the wifi option in phone settings and turn it back on for the connection to work again. It happens every 1 minute or so and it is very frustrating. Please if anyone could give any suggestions.
I am also facing the same problem. Did you get any solution?
Same here, bloody annoying.
Connects to access point no problem, remains connected to access point no problem but it's pot luck if you get data flow.
Using my Redmi right now, so hopefully this posts ok.
