Mi A2 Network problems - Xiaomi Mi A2 / 6X Questions & Answers

Hello guys,
Ive bought Xiaomi mi A2 few days back. Despite overal satisfaction with phone I am deeply frustrated with network.
Sometimes when phone is locked for X ammount of time, when I unlock it I see no wifi or no network signal.
My wifi works worse than my mobile data, which do most of work. If i move like 5 meters from router I almost don't get signal at all.
My internet is optic one, and all other phones when being connected on my home net work almost perfect, pages load instantly.
But with mi A2 lets say, at best it is frustration. Wifi randomly connect, disconnect and much more.
I have reseted it to fabric data, I have reseted network options, I have turned off batery saver option.
I updated system to lastest version. Nothing help.
Even after returning phone to fabric state, I had to download updates for 5 hours. Can someone explain me where I should bring logs (maybe I can do it here, and to check if those are software or hardware problems?)
Thank you,
Boris

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.

Dodgy wifi

Has anybody had any problems with their WiFi not connecting? My device seems to fail to connect to wifi after a couple of days and just sits trying to connect. Toggling WiFi doesn't seem to resolve it, and I have to reboot the entire phone to get it back online.
No problem here.
Connects very quickly, never seen it fail to connect, even on my works dodgy BT homehub 3, which used to tie my old Z3 compact up in knots..
Yep.I thought that Snapdragon 835 cause this problem. Xi oami 6., ZTE z17 and Op5 had the same question with WI-FI connection.

I have a sd835 s8 and I haven't had any wifi issues whatsoever since launch. It's a sample size of 1, but I don't know if it's truly due to the sd835
I haven't had any WiFi issues. In fact my WiFi connections have improved using the XZ1 compact over the X performance (the X performance dropped its WiFi connections 3 times during my data transfer to the new phone)
I've had my XZ1c for about a week now (European model) and it connects to my home network (5G) normally. Signal strength is fine, although the galaxyS6 it replaced definitely had superior reception. I do have wifi issues, but only when already connected to the network. When the phone is asleep (screenlocked) it seems to lose an active connection. The wifi connection should be on at all times, even asleep. It will show the wifi symbol, but data apps don't load, and it will have lost the connection as remote for spotify connect (playing on my reciever). It will also switch to mobile data at random times with normal wifi signal strength (even though I toggled this function off in the developper settings).
I'm not sure if this is something that can be fixed through system updates. I haven't seen any forum posts with similar problems though, so I'll try to document what is actually happening before I contact Sony support.
I bought the US version and flashed the UK firmware to get the fingerprint reader to work. No issues whatsoever with this phone. No Wi-Fi issues, overheating, signal strength, battery, nothing. Everything works just perfectly.
Same issue here. Mine is Europe (NL) version. The upload and download speed can be very unstable. And especially when I take it a bit far way, even you see that it's connect to the wifi with full signal strength, it said internet is unavailable.
I'm not sure if this related to the system update of last weekend or not.
Further to my issue. My phone will drop wifi connection and repeatedly try and connect - it usually cannot see any other networks at the time. Restarting the wifi on the phone, or rebooting the access point do not help. Running a packet sniffer on the LAN shows no activity, which indicates the issue is to do with wireless handshaking.
The problem occurs every few days and the only way to resolve it is to reboot the phone, which fixes it instantly.
I contacted Sony and they told me to do a complete reset on the phone, this didn't work. I updated my findings and pointed out that it's seems to be a firmware compatibility issue. Of course, you only get to talk to first line, and as a reset didn't work, they want me to send it off for a warranty repair (which of course will be returned with "no fault found" as no doubt their wifi will be different enough for it not to have been picked up on day 1 testing).
I'm currently trying to gather a bit more information on the fault, e.g. does it only happen on my home wifi etc. I've disabled channel bonding but that didn't help, and I've not jiggled my DHCP settings after seeing plenty of posts describing wifi problems on Oreo for other phones.
It doesn't happen frequently enough and I don't have the time to delve deeply into the network to identify the cause.
One interesting thing was that it went funny at home, but it was working when I got to work. When I got home it still couldn't connect. So I suspect it's to do with a particular compatibility issue somewhere.
no problem here conecting to 5 and 2.4 wifis...

I haven't gotten around to this yet. Do you still have wifi calling and volte available?

So far my wifi has been fine...
Mine is worst, i couldnt get it to connect at all but all my other device including xperia xa, xzp, laptop, Ps4 PS3, everything connect without any issue whatsoever, already excahnged once and still the same.
Think mine is struggling with either a single access point or VLANs. I need to dig further, but that requires buying a new AP - this phone is getting more and more expensive!
exactly same issue as Dashers describes with my XZ1c. I am not watching it closely, but it seems that it is hapenning after around 2 days online. Never happened before on same network with my previous Z3c, which had run months without restart and any problems whatsoever (till its display died

I have more or less the same issues, and a reboot always solves it. It happens with both routers form ASUS and Draytek.
Additionally I see issues with Spotify connect dropping or not being found on my Sonos (hardwired to LAN), but not so much to Chrome Cast Audio on the same network.
I don't have a problem connecting to wifi, but I seem to have a different issue. Even though wifi scanning is toggled off in settings, my phone still seems to be scanning according to Battery Historian. I think this is one of several things contributing to my high idle drain. Does anyone else have this problem?

Yes, wifi and BT scanning are both turned off in settings and have been since the beginning, but both seem to be happening anyway according to Google's Battery Historian tool. When I go back in to see if they've been toggled on by an app or something, they still appear to be off.

I have this exact problem. One second its 100% signal and is workin as expected. The other second it just drops and tries to reconnect like crazy. I have even had moments when i am unable to find my wifi after said disconnect. All my other devices is working like normal on my wifi. Using Asus n66u 5ghz.
I have been having the same issues as mentioned above with my XZ1 compact(european). My issues with dropping wifi signal seems to be happening when there are two different wifi signals to choose from. They are both on my local network. One is an extender due to the size of my house. When it can detect both signals, it can't make a decision on which one to choose. Once I remove a device(forget wifi device), it stays connected to the other with no problem. Since it isn't trying to compete with the other.
Has there been any improvement on this issue?

Mi 9 bad reconnection when low signal on mobile network

When I am using a mobile network (both 3G and 4G) and the signal is low, sometimes I lost connection (That's normal), but the stange thing is that phone don't reconnect soon and it remains offline. I have to manually reboot or enable/disable airplane mode... and the signal come back.
I'm using Mi 9 for about 5 months. I am on the last firmware and even on old versions same thing...
Anyone has got similar problems?
Hi i have also some problem with my connections, I am from Germany I got my Mi 9 since a week (Rom was Global Europe 10.2.30 EEU) now I have the Global Rom (10.2.13) but this is also no solution.
Sometimes it shows me a Network but I tried to call my girlfriend and it has no dailtone, also it shows me network but I can't receive calls, same problem I have with mobile data, it shows connection but then it isn't connect to the internet.
if I switch off the mobile data connection and switch it on then I have normal connection.
I hope there will be a fix in the next update....I heard that some people have that problem.
Mine loses signal sometimes on the subway but reconnects by itself in 30-60 secs, i find that a bit slow but overall I think it holds onto the signal better than the phones i had in the past. This is the type of issue that would be solved in 1 month at most but here we are, an update almost every 2 months that "optimizes" one thing and weighs in at 500+ MB.
Mine have the same problem. When I'm on the subway it lost the signal and when I go out to the street again I have to enable/disable airplane mode to get signal again, because it can't connect automatically like a normal phone.. I'm from Mexico and I have Global ROM 10.2.13.0

I have a similar problem. Where I work the phone goes from 4g to 3g, to avoid this I open the phone settings 1 (by entering * # * # 4636 # * # * on the call keypad) and switch from lte / td-scdma / umts which is default option to only lte.
The problem remains the same when the phone loses the line and then finds signal again, because although there is signal after I do not receive photos or audio from wa or cannot I access the services of play store for example and I have to switch to default option again...
I'd like to know if there was a method to increase the power of the antenna module even just a little with root permissions ...
I have a similar issue, especially when I am driving car - I am from Germany.
When I start driving with Google Maps open (to have an overview of the traffic), after about 30 minutes my Mi 9 loses connection and won't reconnect, even if I switch on/off airplane-mode etc. This does not happen every time, but relatively often. To get back network connection I have to restart the phone.
About 2 days ago when I was home I lost connection again. Google Maps was still running. After closing the app my Mi 9 immediatly connected to network. That may have been coincidence, but next time I will close Google Maps if my phone loses connection again in the car and will report here.
I am on Xiaomi.EU 9.9.26 Android Q (I just installed *.27 v2), had the same issue on different Xiaomi.EU Android P releases.

It happened to me several times and I can't understand why ...
In this case the connection seemed to be good too, I had all the signal notches in Lte, but in reality it was absent.
I had to restart.
Known problem it seems...?
Hopefully Xiaomi will fix it soon.. wonder if custom ROMS have the same problem

So, as I said I report back.
Today again after about 30 minutes my Mi 9 lost connection (0 bars). Again at about the same region. Probably the connection is bad there. However, my Mi 9 didn't reconnect even after few minutes (sometimes I waited 5+ minutes and IT didn't help).
I closed Google Maps and another App, which requires GPS. Nothing happened. Then I deactivated GPS from the quick menu and my Mi 9 connected immediately to the network with full bars.
I have "o2" as network provider.

I changed to LTE only, and use it for some hours...
It didn't help. Same as before.
Thanks anyway

Yeah, I know, For me is the same.
When I lose connection I've to change to LTE, When it happen again, I've to do it again so I come back to default option.
I do this to avoid restarting the phone and to be faster, but the issue remain anyway...
But remember, When u're in "only LTE" option, you will not able to call
Workaround is change to 3G connection preference
Hi everyone!
I have the same issue and after lot of things that I have done, as change MIUI to Global version, now I can use 3G without problem, but if I try to use LTE/4G after some minutes using GPS in high accuracy, LET connection turns OFF.
So, my workaround is change to 3G connection preference when I need to use Waze, Maps or any other app high accuracy.
I have the same problem too, and I always have to reboot the phone to get the data/wifi to work again. But just a minute ago I had the same problem and I just killed all tasks in recents and the network came back without having to reboot. May be coincidence or I'm on to something.
From experience this problem should have disappeared for quite some time now.
I have always been using EEA ROMs. I believe I have not seen this problem at all in MIUI 12. It has been such a long time since I last saw the problem I don't really remember if this was fixed during the MIUI 11 era.

Try disable and enable airplane mode instead of rebooting

Oneplus 3t Wifi Issue more in the topic

Hello everyone,
sorry for opening a new topic on this, but i cannot seem to find a solution for my issue.
So first of all, my mom has a 3t which was updated a while ago and since then according to her, wifi isnt working, well it only works if it is lets say back to back to my oneplus6t while hotpotting and even then when it connects, it sais no internet. Long stry short, since she has unlimited 4g she wasnt really bothered by this, but since then she upgraded, and its been sitting inthe cupboard for a while. 4g is working aswell, no issues on that, flawless internet, only having issues with the WIFI
What ive done sofar:
- downgraded to os 7.1.1 from the latest 9.0.6
- reset whatever i could, ettings, cache, hard reset
- signal for cellular and bluetooth and nfc works no issues
-rooted the phone now
-opened up the phone, checked the wifi cable, even replaced it
-after opening it up, i saw the liquid indicator turned red on the top left corner of the motherboard
now, it well could be hardware issue, but on the other hand it a bit fishy
because everytime it is scouting for networks, the signal strength seems fine, then it drops and disappears as soon as i want to cnnect
also, i cannot simply just connect to these wifi, i have to setup a static ip address, then it would connect only when it is lets say back to back to my oneplus 6t hotspot.
so when it connects theres no data flow no internet connection at all.
now, has anyone any kind of suggestions what to do next?
thanks for listening

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.
