Question (SOLVED) WiFi5 866mbps only reached in airplane mode after reboot - Xiaomi Poco X3 Pro

Hi everyone, yesterday I decided to upgrade from the Redmi Note 8 Pro to the POCO X3 PRO, and everything is ok except for the wifi link speed, in my old Redmi Note 8 pro it was around 433mbps but in the POCO is 192mbps less than half the link speed.
The reason why I care about this is because I use Wifi File Transfer Pro to send and receive files between the PC and the phone because it's way faster than the USB transfer protocol even at 192mbps.
Update: I can reach 866mbps after a reboot in airplane mode no matter if I change the network to 2.4ghz I can always go back to 866mbps, but as soon as I disable airplane mode and my connection falls below 200mbps (whether it's by distance or by switching to 2.4ghz) I'm unable to go above 192mbps in WIFI5.
Temporary fix is to reboot with airplane mode.
Roms where this happens in my phone:
Official rom (International, Europe, India)
ArrowOS
EliteOS
Xiaomi.eu (current rom)
Any Ideas?
Final solution
So after a long time trying to fix this problem, I found the solution, it worked in MIUI 13.0.7.0 global.
You have to root your device with magisk
GitHub - Magisk-Modules-Repo/wifi-bonding: Double your bandwith on your Qualcomm devices.
Double your bandwith on your Qualcomm devices. Contribute to Magisk-Modules-Repo/wifi-bonding development by creating an account on GitHub.
github.com
Install the above addon for magisk
Reboot and now the phone will reach 300mbps on 2.4ghz
and 866mbps on wifi 5ghz, I haven't tried wifi6 yet
(Why would you want to do this?)
Well most xiaomi devices are USB2.0 and when you backup before restoring the device, the backup at least in my case took 80gb, and when I moved it to my PC it took me forever at 27mbps in a usb3.0 port, same when I use 2.0.
But when you use wifi file transfer pro, you can get transfers around 70mb/s in 5ghz almost 3 times faster.
So you will save a lot of time in large file backups and transfers.

Maybe try different app? The app seems old.
First check when you connect WIFI 5G and test the speed of internet.
Is PC wire-connected to router or through WIFI 5G?

1-The app is old and simple, but it does its work, the problem is the link speed that limits the connection.
2-This is not an Internet speed problem, it's about the link connection between my phone and the router (max theorical speed).
3-PC is wired connected 1gbps ethernet cable, I can sed files beween the local network at around 120MB/s (1gpbs)
My old Redmi Note 8 Pro link speed is 433mbps and it sends an receives at around 40mb/s, the new POCO Sends and receives at around 12-20mb/s

1. Compatibility issues between Android versions?
2. To check if your WIFI 5G is fully functional on POCO X3 Pro at full speed through internet.
3. So rule out PC and it's link to router issue. Cause still to be found.

1-The APP works fine, the app it's not the issue, the problem is the link speed that limits the app.
2-The 5ghz wifi it's fine, I attached the screen captures where the Redmi is at 433mbps and the POCO is at 192mbps.
Router is set on channel 36, bandwidth 20/40/80mhz, MIMMO enabled, and the distance from the router is less than 1m, same problem with the repeater (which allows around 1gbps speed over 5ghz wifi).
So far seems like a hardware limitation, it could help if you share your 5ghz network info to check your theorical speed.

When you unlock bootloader, your phone will be like a factory reset. If after that is still not fixed, I don't think flashing different Rom would fix it. Hardware issue or compatibility issue may be possible.
Try reboot both router and the phone. (power off, then manually power on with pressing power button.) Sometimes it will magically fixed.
Reset phone connection setting (should be in factory reset menu), then add WIFI setting again.
Find another router with 5GHz and connect to it to see if it's actually your phone's problem or router problem.

So after researching, reading trying everything, up to this day I've been unable to fix this problem.
At this very moment I'm in safe mode (Xiaomi.eu 12.5.3) and the connection is 866mbps.
I'm able to switch between 2.4ghz (192mbps) and 5ghz (866mbps).
Now there is one thing that I just discovered, if I boot with airplane mode, as long as I have it enabled I can switch between 2.4ghz and 5ghz without any issue, but the minute I disable it and try to switch, I'm unable to recover the link speed.

According to your update, you said ArrowOS and any MIUI ROMs had the issue.
Tried other ROMs?
If all the ROMs you tried had this problem, it may be firmware/kernel sourced and maybe Android 11 issue.
I think I've seen some people on this phones or other phones had WIFI issues, and had reported improved or somewhat compatible when without using mobile data and changing WIFI router to 802.11 a/b/g/n which is old and better stable, but may have slower speed.
If MIUI has this issue, you can report to Xiaomi with your video.

Yes I tested all the roms for the same purpose just to check the 5ghz link speed and all of them resulted in the same 192mbps what kernel do you recommend me to start testing?
I don't know, following my logic I've come to think that my phone has a hardware problem, maybe interference or a bad contact in the antena and the link gets throttled down to prevent data loss, but that's just a theory however I want to fix it.
One more thing, my brother has a Redmi note 10 and my mother has a Redmi Note 8, and they both experience an identical issue, but they are limited to 96mbps (half my throttled speed 192mbps), and if the reboot with airplane mode and wifi enabled, they both reach 433mbps (half my full speed).
So I'm almost 100% sure that there is a problem with the kernel or the modem firmware that's causing this, I just want to find out how to fix it once and for all.

Some Custom Kernels are listed in the Index thread, you can try to see if any would help, some custom kernels may only be accessible in Telegram group.
I'm not a developer, and not into coding, so can't help on solving. You can try and ask in Telegram group to see if some developer knows how to fix it, and the response there should be faster than in XDA.

Just tried Etherious kernel 3.0 (3.1 was incompatible) but no use, 192mbps persists, perhaps it's just a firmware/modem problem, probably I will be selling this poco and purchasing POCO F3 instead, hopefully that phone works better :/

I would say try a non-Xiaomi phone to test.
All your phones you listed are Xiaomi-related brands, and all had similar issues.
If you buy, lets say Samsung, and the problem still exists: it's more likely your WIFI router's problem.
If Samsung phone or other brand Android phone does not have this issue, it's more likely Xiaomi's problem.
You can still buy Poco F3, but it's not easy to find where there problem is from if test only with Xiaomi-related brand.
You can try iPhone as well, but since iPhone are completely different design, it's not easy to find out where the culprit is.

Everything depends on the antenna and the modem used in the device. It should have been optimized to work at 2.4 Ghz (which is actually good as 2.4Ghz is used more then 5Ghz in most cases). The airplane mode is not an issue. When it is turned an and turned off later, the modem is triggered immediately in which gives you a spike in speed. Just like, if you take rest for a while and run, you run faster then when you keep running straight!

2.4ghz wifi networks not working

Hey guys,
Flashed stock 5.0 on my nexus 5 using TWRP.
After the device booted up, i noticed it could only connect to 5ghz wifi networks and not 2.4ghz.
Any ideas why this is occurring?
Cheers
Same here
Yeah strange. I'll try re-install the stock ROM and see if I notice anything different..
Yes, exactly the same problem here. Funny thing is that I can see the network, but can't connect.
EDIT: So it seems there are multiple issues, found some bug reports related to what I'm experiencing:
https://code.google.com/p/android/issues/detail?id=78702
https://code.google.com/p/android-developer-preview/issues/detail?id=1548
https://code.google.com/p/android-developer-preview/issues/detail?id=1620
Oh ok, I can't even see them. Do you get an error, or the phone just refuses to connect with an error msg?
On WLAN Settings there is a Menu called Advanced
There you can select if 2,4 GHz, 5,0 Ghz or automatically both.
Maybe after putting automatically you see them both?
I seet the WLAN, can put password, but it tries to connect and then stops connecting and always tries to reconnect from time to time...
Thanks guys! I worked it out. My routers 2.4ghz band was on channel 13, I changed it to 7 and it showed up. Don't understand why it couldn't see it before, but now it works! Hooray! Cheers!
If you're having troubles guys, try to tweak the channel on your router

And what if your network at work has above 11?
Then you can't do sh**... Seriously Google
Yeah, WiFi in 5.0 is major screw up. There are at minimum 3 major issues:
- 2.4 GHz band channels above 11 unusable
- https://code.google.com/p/android/issues/detail?id=78702 (or https://code.google.com/p/android-developer-preview/issues/detail?id=1548 reported on developer preview)
- https://code.google.com/p/android-developer-preview/issues/detail?id=1620
And then there was that excessive power consumption related one - supposedly responsible for the 5.0 release delay.

WiFi problem

I've noticed WiFi problem in my moto g 2015.
My home WiFi is not connecting, it reacts like gone through infinite loop. My home WiFi is having WPA2 protected access.
Every else's WiFi is connecting to my phone.
Please help.
It would help if we had much more details. A link to a video would be perfect. Does this happen with any other Wi-Fi networks?

Did you manage to resolve your wifi problem?
I bought the Moto G (2015) 2GB RAM / 16GB ROM for my wife and she's having problems with the home wifi. It often says there is a "connection error" and loops to try to connect again and then fails. Her work wifi seems to function ok.
Having read about similar problems with older moto gs, people recommended (1) turning on and off airplane mode. (2) changing channel number of router.
Both sometimes work and sometimes don't. But it's not really a permanent solution. I'm a bit reluctant to do a factory reset and reinstall everything if it won't resolve the problem. The device came with the latest firmware already installed (5.1.1) and I haven't rooted or unlocked bootloader so should be a pretty clean install.
Anyway, would like to hear that factory reseting could resolve this issue or not before trying.
Thanks for any advice!
Mine does it every now and then. I just unplug my router, wait a minute, plug it back in, and then it connects.

Yes. It works for me too. But what happens if you're on a public or work wifi where you can't reset the router? It doesn't really seem like a long term solution.
Is this a standard problem with this phone? Anyone else have a similar problem or preferably a solution?

Yeah resetting other than home router is not the answer. It's an Android issue as all my phones do it from time to time. I haven't been able to figure it out. The other "fix" if you can't reset the router is try going into the Wi-Fi settings, and forget the network/name, and then add it back as new. It takes longer, but it could work for you. That's how I get around it when connecting to work when it won't auto connect.
Hi, I had also faced the same problem with a open wifi network which is free for 15 mins ..
Other than that one ..i had every router connected to my phone..
I was thinking the problem is not in your phone.. It's in router which might be old ��
Because old routers will have 802 a or something which are in compatible to some phones..
Or the router is not allowing your phone to get connected.. As your phone is latest and it has advanced protocols inscribed in it..
Do one thing.. Shed some light on this now :
1) router model (if known to you)
2) phone models which got connected to that router and it's operating system version (like 5.1.1)
And there is also one more point.. I found our phone might find problems connecting to 5ghz band router ..while it works fine for smaller routers like 2.4ghz
We can decide when you dig some info about the questions I mentioned...
We will get answers
Just turn off wifi and then turn it on it will fix the problem

My router is a netgear CG3100Dv3 (using WPA2-PSK [AES] encryption) and uses 2.4 GHz. I don't think it's the router's fault though because I've had many friends connect with a variety of phones and none of them have had the problem before. I currently have a Oneplus One (android 5.0.2) and have used a Nexus 4 and Samsung Galaxy S (1) on this router without problems. Maybe it's a problem with android 5.1.1 as I guess not many of my friends have it yet. I've written to motorola support but they still havent got back to me.

Strange. I've never had a problem before with wifi. Maybe I've been lucky until now. Yep - have tried forgetting and reconnecting to wifi signal. Again, a temporary solution that will quickly become irritating when there shouldn't really be a problem for such a simple operation.

It's a temporary solution but a pain in the arse if you have to reset the router every few hours. And as I said before, what happens when you can't connect to a router which you can't reset? (i.e. public, work)
Change the router's channel, then refresh the wifi in the phone.

Firstly i agree that our Moto G has some kind of issue with some routers.. but there will be solutions for them from the ROUTERS POINT OF SIDE to make it work
i have read about your router .. Things i suggest (if you have already done them then let me know )
1) your router has option to change MODE to get speeds more than 150mbps.. try changing that 802.11 MODE , restart your Phone and Router and also keep CHANNEL to AUTO , try changing the security WPA to others also..
2) your Wifi of your phone will have a MAC address , copy that and paste in your Router to allow this device..
i am still finding info on your problem..
the reason why i think your Router can solve the problem is : i had once read about 802.11 b/g/n/ac types.. i am getting a doubt that they are the ones causing the problem.. if you are aware of it
have a look at this bro once : http://www.smartmobilephonesolutions.com/content/cant-connect-to-wifi-on-android-smartphone

Ok. Will change channel to auto mode. It was already on "up to 300 Mbps". Will also put MAC addresss in the router.
However this still relies on having access to the router. What happens when you don't have access. If this is going to happen on many routers then I prefer to return the phone and buy one which never has this problem.

I'll give a wifi fix app a go to. But they just seem to automatically delete known wifi SSIDs and passwords.
Another option would be to root and install new ROM and radio, but would prefer not to.
It seems like a lot of Nexus 5 users on 5.1.1 are having wifi problems too:

Just a quick update if there is anyone else reading this thread with a similar problem.
I changed the channel mode to auto and that has seemed to fix the problem. The moto g seems to connect without problems now. I didn't enter the MAC address nor used a "wifi fix" app so far.
Fingers crossed...
I have the same problem. Wifi just stops working and had a ! Symbol beside the wifi icon. I have probably had a 100 phones and devices connected to this router without a problem. I have changed a bunch of settings the router and it didn't help.
Disabling wifi off then on works, but that is no solution. I will try anther Rom or kernel. I am on resurrection 5.1.1

My problem was slightly different in that the phone wouldn't even connect to the wifi signal. It would cycle continuously between "connecting" and "authentication error".
Does it work with other routers?

Thanks for your help! I'm still a little wary that the phone will have problems in the future on other routers, but it's a good enough fix for now. Hopefully a later firmware update will sort it out.
Unfortunately, my wife took the moto g on a business trip last week and could not connect to any wifi signals (her colleagues did not have a problem).
Not sure what to do now. I'm in contact with motorola support but they don't have any suggestions yet (apart from blaming the router - which has never had a problem with any other devices!)

Unfortunately, my wife took the moto g on a business trip last week and could not connect to any wifi signals (her colleagues did not have a problem).
Not sure what to do now. I'm in contact with motorola support but they don't have any suggestions yet (apart from blaming the router - which has never had a problem with any other devices!)

Well I just emailed Amazon and they're sending a replacement. Hopefully this will solve the problem

Wifi problem on MIUI 12: Disconnects & Ramdump

After updating to MIUI 12.0.1.0(QJKEUXM) there are sporadic WLAN reconnects (8 to 10 per day) and only when the device is in screen-off state for some time.
In addition, there is a folder "ramdump" that fills up continuously with files like
ramdump_wlan_2020-08-03_20-48-05.elf and
ramdump_wlan_2020-08-03_20-48-05_dmesg.log
for every reconnect.
This folder now contains 358 files with 2.54 GB of ramdumps!!!
It started all with the MIUI 12 update. The first ramdump file has a date right after installing MIUI 12. On MIUI 11 Wifi was fine.
I tried every setting (Wifi Manager on/off, disable IPV6, fixed IP, fixed channels, etc.), but the problem remains.
Could you please check, if you also see ramdumps from wifi on your device and report back here?
It would be awesome to know, whether I am the only one with this problem. In that case, I would go through the hassle of a hard reset. Otherwise, I would just wait for another MIUI update...
Thanks.
The folder ramdump exists in my device but it's empty.
I didn't notice any WiFi disconnection. In MIUI 11 5G WiFi networks suddenly disappears but seems to be fixed in MIUI 12.
BTW, when you said "disable ipv6" you did it in your router or in the device? (I don't know how to do it in the device).

I did this on the router. I don't think there is a setting on the device itself.
And thank you for checking on your device, appreciated.
As you said that disconnections happens when device is screen-off maybe the problem is related with a kind of Power Saving option. Check if you have any WiFi Power Saving option active in your router.
For instance, in my router I have disabled "RX Chain Power Save" in both WiFi bands (2.4G and 5G). I have also disabled the Ethernet Power Management options, but I think it should not be related to your problem.
Good luck.
My router only has Power Management options for LAN, but not for WLAN.
I am on a combined mode 2.4 GHz/5 GHz on a single SSID. I could separate both to end up with separate SSIDs for each frequency. This is the only setting, I did not try yet.
Just to let you know. I found a solution:
In my router, I changed wifi encryption from "WPA+WPA2" to " WPA2 CCMP" and the problem is solved.
Weird though that this setting never made any problems before, not with my old phones and not with MIUI 11.
Having exactly the same problem except changing WiFi encryption doesn't solve it. Is there anyone else with this issue?
I need to turn off WiFi6 and all problems are gone.
I used to have the same problem on a OnePlus device, and this was the reason:

If it starts to drop out again, split the SSIDs.

December 2020 security update is now available

Hi,
Just received it, but only 3,6 MB. So I guess none of the bugs have been fixed.
Cheers
Add another email account and Customize your Pixel still present
Updated today, did usual reset through recovery, my daisy works fine. Atm zero annoying tips in settings.
Will the December update fix the multitasking bug on Mia2 lite ???
So I just updated to V11.0.16.0 via fastboot.
I am still having the same problem (since my first upgrade to Android 10 about a few months ago) with my Wi-Fi. Every 20-30 seconds, Wi-Fi connection is lost. Then after a few seconds of waiting, it is established again. Then after 20-30 seconds, Wi-Fi is again lost. It goes on like that, endlessly until I just deactivate Wi-Fi and use mobile data... but this cannot be the solution, don't the Dev's have to notice something is wrong with Wi-Fi??
Is anybody else having the same problem with Wi-Fi?

Before upgrading to Q, on P, zero wifi' s issues ?
Maybe something' s changed in your area, new wifi signals could interfere with your device.
Have you checked other devices, like a pc or other mobiles ?
If your router is dual band you might try 5ghz, daisy works fine in my experience on 5ghz regardless of android version.
Did you try a reset from settings or recovery in these months in search of improvements ?
Personal curiosity, why did you use fastboot for updating your device ?

I only have a 2.4GHz router, but the problem is happening no matter which channel I choose on the router setup (i.e. the frequency within the 2.4GHz band).
We have several Wi-Fi devices in this household, including Wi-Fi repeaters to strengthen the Wi-Fi signal around the house... end user devices include multiple notebooks that use Wi-Fi access, a Smart TV and I also use another smartphone as a backup (Nexus 4) and neither of these devices does have any problems with the Wi-Fi.
Also, my brother is using the same phone the same way (with fastboot flash every time there is an update available) and he is having the exact same problems with Wi-Fi on his Mi A2 Lite.
Also, the Wi-Fi issues are the same when I am at the library and connected to a different Wi-Fi. So in my opinion it is unlikely that there is a problem with the Wi-Fi at home.
Around the time the Android 10 update became available, I started activating Bluetooth on my device 24/7. However de-activating Bluetooth has no effect and my Mi A2 Lite still loses Wi-Fi connection just as often.

Reset from settings only, but it should not matter because I am flashing all partitions every month, whenever an update is available and the problem is happening as soon as I completed the flash and started the device for the first time.

I am using Magisk to gain root access to this device. There is a guide on XDA that I follow for doing the update via fastboot, so that I can continue using Magisk. As far as I know, OTA update still fails when any of the partitions has been tampered with, for example by installing Magisk and patching boot.img.

If the wifi' s issue began for both devices, yours and your brother' s one, after you decided to use magisk on stock rom it could maybe be the monthly flash procedure the reason of such problem.
Have you tried to flash a custom rom and check if issue continues to occur ?
Personally, as reported, i' m using 5ghz wifi without any issues, zero disconnections on last stock december build.

I think I was not as clear in the post above. We have both been using the Mi A2 Lite with Magisk and Android 9 since December 2018. So we used Magisk to root the phones right when we got the phones. We had no issues with Wi-Fi on Android 9 with Magisk. Only when we updated to Android 10 in spring/early summer 2020, we encountered the connection issues.

I did not do that because most Custom ROMs that I found for this device have problems on their own with some features, and I like having a nearly stock Android experience. However, I get your point that this might be a good opportunity to check whether or not this is a problem with the official Xiaomi ROM or the Mi A2 Lite's Wi-Fi modem, i.e. a hardware problem maybe.

Could you check if your Mi A2 Lite works on 2.4GHz Wi-Fi without disconnection issues? From my experience, 5 minutes of testing would be enough. Usually I see the first disconnections within 30 seconds after I activated Wi-Fi (2.4GHz) and disabled mobile network.

Checked rn, 10 mins on 2,4 ghz, wifi works fine, zero disconnections.
About custom rom, you could try los17.1 from Reujea0 or crdroid from Opal. Imo los and crdroid roms are very close to stock experience. Moreover, i recently read on los17.1 thread that dev would like to switch to next release, los18, anytime soon.
And yeah, you should avoid it isn' t an hardware failure.

Thanks for checking this out and getting back at me. I did some further research, as I found out that another user on mi.com (the official Xiaomi forums) reported that when updating to Android 10, he had problems with switching between WiFi's (switch took a long time, download/uploade rate on WiFi very slow, https://c.mi.com/thread-2854872-1-0.html).
I then disconnected the repeaters on my network and found out that WiFi on my Mi A2 Lite is working without any problems, as soon as the WiFi router is the only WiFi host and no repeater is used to extend the range of the WiFi network. Maybe there is a problem when the device is handed over between repeater(s) and router within the same WiFi.
The Mi A2 Lite is my daily driver. As soon as LOS reaches official status, I will flash it on my device and try it out. For now, I will just continue using Mobile Data.
I think after update phone has less lag. Still have to reboot, but it is a little better

Hotspot disconnecting each 8-10 minutes, no way!!!

I had a terrible deception when I renewed my Xiaomi Redmi Note 8 Pro for a _Xiaomi Poco X3 NFC, because I thought that the connectivity issues I had with Redmi Note will disappear in the Poco X3.
The problem is that each time I use my hotspot wifi connection to share 4G internet with my Surface, or my Amazon Fire, after 8-10 minutes suddenly wifi connection stops, and I get my device frozen in the middle of a film, TV series, etc.
I use it also to work outside, and the only remedy I have so far is to press the bottom on the side to unlock the phone each 4-5 minutes, if I remain doing this the connection stands.
Anybody have the same issue? How can I fix it?
I read time ago when i had the redmi that it was something iremediable in MIUI, is that true???
Thanks to all, I am desperate.
Not a real solution but you can always set the device to remain unlocked at your location and always on -- better plug in the charger while this is on, BTW...
In Hotspot settings there's an option to automatically turn tethering off if no device is connected. Though it shouldn't make a difference as you're actively using it and it turns off anyways. In developer settings there's a switch for Hardware accelerated tethering which is supposed to lower the power consumption of said function so it might affect how long it stays on.
I can't fix it, anybody could tell me a solution????
Isn't anybody else suffering from this, or simply nobody cares about it??

Assuming you have tried the settings I suggested and the workaround from pnin your best shot is probably doing a Factory Reset or flashing the full stock ROM and doing "format data" to exclude a hardware issue.
As you can see it doesn't look like a common problem with our device as over a hundred people have seen this thread. Two of them are trying to help you.
PS: I've just tested it by watching a 20 min video on my huawei tablet connected to POCO X3 hotspot no problem. It hasn't disconnected and the Hotspot is still up.
But it is a new smartphone, it started from the first day I had it. How can a factory reset fix something that was since the very beggining??
It happens to me everyday and now it is still happening.
The only other option is that my Surface and my Amazon Fire 8, both of them disconnect automatically from it, which is very strange thing.
same problem with me, im using POCO X3 GT its a new device, which i bought it two month ago, its keep disconnecting from my PC, when i using tethering either, wifi tethering or USB tethering both have same problem,
after a certain time, its keep disconnecting, and weird, that the no connection show on my PC, but while i checked on my Phone, it said still have connection,..
please give me some solution....
ive got the same issue here, just got used to it ... ive given up on all the solutions here there and everywhere ... i think its a bug in the software of the redmi note 8 pro ...

Hi guys i would like to announce that I might just possibly found the solution to the disconnecting issue. 3 steps.
The first step go to your setting .
Second step find for the battery and performance setting.
3 steps find the setting symbol in the battery and performance page.
You then might see the a command "turn off mobile data when device is locked" set to 5 minutes or what so ever in your default then change it to never.
This should solve the problem off the hotspot keep disconnecting when you connect from the external device.
