[NEED URGENT HELP!] Wifi Problem - Xiaomi Mi A1 Questions & Answers

I've installed many custom ROMs, reflashed with mi flash tool, but the problem still persists. So, the problem is, when I'm 10 metres away from the router, I get 0-2mbps. I can barely watch a YouTube video at 1080p. However, when I'm next to the router I get 42mbps. I have confirmed that the problem is only on my phone. Can someone help me?
Things I've tried :
- Installed custom roms
- Factory reset
- Reflashed with mi flash tool
- Remove lines in wlan_mac.bin
- Reset network settings
P.s. sometimes I get 0 bars which doesn't happen on any phones, and sometimes I get 'x' in the wifi icon indicating I have no internet.
P.p.s. When I put my phone on battery saver mode, I have no internet connection. Nothing will load.

Are you using Pie?
Try disabling\reenabling GPS and \or Bluetooth.
They slow down 2.4 GHZ WiFi.
When you're next to your router probably WiFi switch to 5Ghz.

How I solved Wifi problem

Lately I have been reading many post related to Wifi problems in the HD. I had the same. Even I was very near my router I couldn't connect to the net and the signal was very weak.
So I entered my router configuration and I found a solution.
Before, for security options I had: WPA-PSK [TKIP] then I changed to WPA2-PSK [AES] (of course you also have to change your HD connection configuratoin), and now it works great¡¡¡¡
Now I have all the bars for the signal and I can connect very easily.
Hope it works for other people
I have a similar WiFi connectivity problem, but after reading of the poor service provided by most vendors and HTC itself, I will try to gather some more experience with the problem before I contact HTC or my vendor, and hopefully find a solution. Bellow is my experience so far:
I own an HTC Touch HD since January and have a similar problem, only it surfaced last week. Before I had only used the WiFi connectivity briefly. The problems started after I installed an AP on my house expressively for the new PDA. The node is fully open and set to B/G/N protocols.
After a couple days of medium (couple hours per day) use the WiFi connection suddenly quit, the device would try to connect (the top bar showing the WiFi connection animation continuously) and after a few moments gave up with a dialog box stating the current network settings were wrong (even thou they worked fine a few hours earlier).
I tried several hot and cold resets, but only solved the problem after flashing a new ROM; even then the same symptoms reappeared after a couple of days of regular use. Again no re-setting would cure the problem, and now not even flashing the ROM again would work. Nonetheless, some hours latter the WiFi would connect perfectly with the same nodes it refused to before, and in very short time.
I have witnessed this cycle twice and have yet not been able to find a trigger for it, but will keep my eyes open for any tell tale signs, and post any findings here.
I could add to the above mentioned problems.
i got a new hd just few days back.
The wifi worked great. But now it doesnt.
I have disabled wifi, so can start it whenever i require.
I click on wifi button to enable it.
Then open opera, try any website.
it will open fine.
For instance say my email at gmail.com
Now after that if i try to open anysites or even continue with my mail, it shows error saying connection not available.
One of the workaround is to go back to toggele wifi off and switched it on.
Not sure if anyone faces a similar issue.
I's been about a week since my last post and I have already witnessed a couple of cycles of WiFi connecting perfectly and then not connecting at all.
No matter the settings I try after it decides not to connect, it won't. Even to nodes it had connected perfectly and fast jus minutes before.
I thought re-flashing might help but so far has proven ineffective. Once I thought some part of the non-volitile memory was causing the problem since after I cleared the memory I could connect for a while.
Any thoughts anyone?
Same problems here.
For the last hour I have been reading 10ths of threads here concerning WiFi problems.
My HD's WiFi worked fine on my home and outside for about 2 months. Now it doesn't. It reports connection, but no program can use the internet. At best, it seems to be able to exchange some Kbytes the for just a few seconds after a connection is established. Then nothing. Connected but unusable.
Tried everything Internet/My Work/My ISP, WAP enabled/disabled, soft/hard reset, everything.
When connected through ActiveSync everything works fine, all programs see internet.
Has anybody taken their HD to the service? Has any HTC service worldwide identified the problem as hardware and solved it by replacing something?

I have just encountered a similar problem, but already used wpa/wpa2 with aes. Have tried a hard reset with no joy. My old HTC Touch has no probs connecting via wifi nor does my laptop so I would surmise that the prob is with the HD and not the router.
I am going to try flashing with the latest version of Duttys 6.1 rom and see what gives.
Edit: Tried flashing with new rom with no success. Take a look at this post.
http://forum.xda-developers.com/showpost.php?p=3769339&postcount=7
There are a couple of files to download but i only used the second ie this one.
http://forum.xda-developers.com/showpost.php?p=1363759&postcount=2
Now no problems and can connect via wifi no probs, ip address assigned by dhcp.
Try to go into WiFi settings and move the power slider to max performance. I need to do it here to access my router. This happened also with my HTC TyTN II, with any recent radio firmware. The original WM 6.0 ROM and it's radio work fine in low power mode, but the new ones appear connected but are always at 1 Mbps and there's no traffic until you move the slider to performance mode.
You go into WiFi settings and you configure manual IP and DNS so as router.
DNS is important.
Whit manual configuration, Wifi work always.
(sorry for my english)

This is not a solution. I didn 't buy the device to be able to connect to my home WiFi only. What about public hotspots? Or hotels? Or whatever outside your home?

[SOLVED] Strange Wifi problem, need help

Hi
I have a problem about accessing internet using wifi. I connect to network, it's ok. But after nearly 30 seconds i cant access internet anymore. My phone says everything is ok, i am connected to my modem, my internet connection is ok but i cant use it on my HD before turning off- and on- my wifi. But i can only use internet for a short time again.
I tried hard reset but everythings is still the same. I am using BlackstoneHenge max stability&speed rom.
So what causes that problem? What should i do?
have you tried turning off your router and turning it back on after a few minutes ?
also try and set the wifi signal strength of the blackstone to performance and not battery. that way, the signal will be stronger and probably not drop. i had the same issue yesterday after flashing another rom, without setting it to full performance, the wi-fi would constantly drop signal and even when i was connected, it would not access the internet properly.
thanks chef_tony and mjuksel
i disabled power save mode of wifi and set to performance mode as you suggested. my problem looks solved now, thanks so much
Solved, thread closed

"Failed to connect to network"

Lately I've been having serious trouble connecting to Wifi networks. This occurs both on my workplace network and home network. I have tried resetting my Network Config, but this didn't fix anything. The only thing I've found that will allow me to connect to Wifi is to restart the device - but I have to do this every time I want to connect to a different Wifi network than I was connected to previously.
One strange thing that happens with this is that when I disable Wifi - whether it be via quick settings or in settings - it doesn't actually disable Wifi. The toggle switches to off, but I'm still able to see nearby Wifi networks. The only way to fully disable Wifi is to enable Airplane Mode.
This has been happening recently since I performed a Factory Reset, flashed the latest factory image, and rooted.
Anyway, any help with this would be greatly appreciated!
UPDATE: Looks like switching from Automatic Wi-F- frequency band to 2.4 GHz fixes the issue, but that's not really ideal, as I prefer my 5 GHz network at home.

Wifi and 4G stuck together - how to fix this?

I know i'm not alone since i've seen this issue not only on my phone. When i'm at home my phone is mostly connected to wifi. My router is Linksys AC1900. Sometimes both the wifi and 4G icons appear together. when this happens my battery is draining like hell. a simple restart of the phone or the router is not a solution - i found that in order to make the 4G icon go away i need to first turn off the router so the phone is connected only to the mobile network, than i have to turn off both the data connection and wifi of the phone; than i need to go and clean the cache through the builtin recovery menu. the problem is that sometimes even performing all these things is not enough and the 4G icon won't go away. Download booster and Smart network switch are both turned off, but playing with them do not really affect the issue. also i tried connecting to both 2.4 or 5ghz wifi with no difference. i also tried setting a fixed IP address for my phone, but again this does not affect the issue. any ideas? i'm pretty certain that it's not a hardware issue since i've seen it happening to other people too. it's quite annoying since it's totally destroying the battery life of the phone and it seems that there's no real solution for this behavior.
What model number is your phone? Have you considered reflashing firmware / factory resetting the phone?
The model is 935f. I've tried reflashing with stock several times (the phone is not rooted) but after a while the problem comes back. This is the only issue I've had with this phone but it's quite annoying.
I've got the same issue. The only solution i've seen till now is to reflash with a custom rom.
Same
I have picked up the same type of issue. I did some snooping around and have found that if I have my mobile data on when in the streets and when I get home and I turn on my wifi, that if my wifi signal is very bad and my mobile data is on, then it would show both signals. It's as if the phone tries to get whatever data from both, since the wifi is so bad. I agree that it really chows the battery. The only fix I could get to work is to switch of the data and move closer to the wifi where it's the strongest. I will sit at the router for a minute or two, It then automatically removes the 4g sign and only works on wifi. If I stay where the wifi signal is bad and disable mobile, it stays there even though my data is off.
Did you do a factory reset and restore your phone to its original settings?

5Ghz Wifi help.

Ok, so I have a us997 LG G6, and it refuses to connect to my home 5ghz wifi (NETWORK_SELECTION_DISABLED_ASSOCIATION_REJECTION=1), its done this on nougat and oreo, i figured it was something wrong with the wi-fi radio/chip, whatever, but today I looked into it more, get ready, because hopefully someone can explain this on to me...
1. If I try and connect to my home's 5GHz wifi it has the error "NETWORK_SELECTION_DISABLED_ASSOCIATION_REJECTION=1" then the network disappears completely. (Wi-Fi analyzer shows nothing on 5GHz)
2. (at this point i tried to see if it was all 5GHz networks or just my router, so i started a hotspot from another android phone (Galaxy s5) and connected to it, and BOOM, connects right away (5GHz, channel 149, 'Very good' signal strength (makes sense, the devices are within a foot of each other), ok.
3. So I set my router to channel 149 and connect to it, it connects but has very poor signal strength, despite being no more than 3 feet from the router... honestly, i'm lost now, so I figure ok...
4. I turn off the hotspot on the s5... and IT DISCONNECTS (from the home network), and then the home network disappears... honestly, what... so now i am completely lost, I just want my 5GHz wifi. please help XD
(any other device i try connects completely fine to my home network...)
(AND on top of this all, I can make a hotspot on the G6 on 5GHz and it works just fine, devices connect with proper speed and 5GHz band!)
edit: If i am connected to ANY wifi network (5GHz or not) the 5GHz home networks shows up, but it still cant connect, when i disconnect from all networks, it disappears again)
TEMPORARY SOLUTION:
Disable WiFi
Go to the service menu (us997: *#546368#*997#) (h870: *#546368#*870), goto field test > WiFi test > select 'core both'. Press start
Go to the root of the service menu again, goto FTM test > select 5.0GHz, press start, you should see a 'Start Successful' message.
Exist the service menu enable and disable WiFi a few times, and that should fix it... Thanks to: cabal06ba for solution!
I don't know the details but when I unboxed and rebooted G6 for the first time, it didn't catch the 5 GHz signals either. I've searched some and found out that this was a common issue. Some people said "restoring the phone to the factory defaults" solves the problem. I've immediately done a restore process and 5 GHz is working like a charm now.

I've reset my phone a bunch of times between updates and rooting mishaps, and nothing (not in the mood to do it again), i will try resetting network settings.

Network Settings Reset didn't do the trick for me either but with help of your first post edit I've found a fix (long-term functionality not yet approved):
1) Go to phone and dial *#546368#*870# to enter the hidden menu
2) Go to field test > wifi test > OTA
In my case it was disabled and enabling solved the problem! (actually I don't even have a clue what this setting is exactly for, found out through trial and error)
3) Then went one step back, entered FTM test, set 5GHz, started and boom, "start successful"! (before it had failed)
4) Finally I went back to regular WiFi-Menu, was switched off so had to turn it back on, no networks, off an on again, 5Ghz was back and still is after several reboots + resetting network settings once again to double check.
Hope that works for others as well!
Don't have an WiFi hotspots that are 5ghz near me now, I will test later, but I have tried using the WiFi test to enable 5ghz before and it didn't work
Edit: Well it said start successful, so hopefully it worked (BTW if you are on a us997 device replace the 870 code in the number with 997)
Edit 2: Devcheck reports '5Ghz support: yes', previously it reported no. Thanks!
Edit 3: Still does not stay after disabling WiFi
Also Even after a factory reset, still stuck on 2.4G
(Cant attach image for some reason, Error 500)
Without a registered SIM card, wifi works at the lowest common denominator on the G6: 2,4ghz channels up to 11 and 5ghz 36 to 48.
So where mobile signals are too weak, wifi is also limited.

I have a registered SIM, I'm on Verizon, Mobile signal is weak everywhere but standing outside a tower because its Verizon...
Once the phone had been registered with the provider, wifi is fully supported even w/o mobile network. Provided the SIM stays in and you don't perform a factory reset.
I had to get a nano sim in order to use my G6. It "unlocked" my G6's wifi, but i continued to use my trusty S5 for a while, so the G6 reverted to bad habits.
Part of the G6's antennae are in the metal frame, but i don't know which ones. These work best while kepping gripped, with no insulating case. While not bridging them all electrically with your hand, which is no good.
The first device with frame antennae, the Iphone 4 had to be modified for this reason. The first batch required the use of a rubber case or frame.
In my case, 5GHz did not work as long as the bootloader was unlocked. Even after I reinstalled the original OS via LG Bridge / Repair. Once I re-locked the Bootloader again, the LG6 connected to 5GHz.
I hope there is a way around this. Probably this behaviour don't apply to custom roms.

I'm still having the same issues, doesn't matter if it's stock ROM or custom , really don't want to relock my bootloader.
