Hello xda members, I am facing a serious problem of 5GHz wifi netwroks. My university routers have two frequency ranges 2.4GHz and 5GHz. And as Mi A1 also support dual wifi band so my phone keeps on switching wifi networks and it remain unstable even if I sit under the router because when it connects to 5GHz network it become unstable and again connect to 2.4 network and then keep on switching networks. both the networks are single and doesn't show different frequencies and it only show frequency when it connects to network .I googled this problem but not found a satisfactory answers. Actually there was a feature in android nougat to select wifi band manually but this feature was removed in oreo and pie. Kindly suggest any solution. It would be a great help.

I personally think that the Android one team at Xiaomi is trying to ruin the mi a1. I think they're trying to promote the mi A2 more. As I'm still facing issues with wifi not connecting and automatically disconnecting in custom ROMs. There is no solution as of now, and I've lost faith in Xiaomi's Android one program. This is probably the worst purchase decision I've ever made. I'm going to move to the mi 9 se. My Mi A1 is only a year old..
[Guide][Root] How to disable 5 GHz Wi-Fi
Following this post by Ironsigh on LG G3 subforum, I was able to disable 5 GHz Wi-Fi on my rooted Xiaomi Mi A1:
Open a root shell using adb:
Code:
adb shell
Navigate to /vendor/etc/wifi:
Code:
cd /vendor/etc/wifi
Mount /system as read-write:
Code:
mount -o remount,rw /
Open WCNSS_qcom_cfg.ini:
Code:
nano WCNSS_qcom_cfg.ini
On line 253 (your line number may be different), change BandCapability=0 to BandCapability=1:
Code:
#Preferred band (both or 2.4 only or 5 only)
BandCapability=0
Possible values are:
0 = Use both 2.4 GHz and 5 GHz
1 = Use 2.4 GHz only
2 = Use 5 GHz only
Save the file and exit the editor
Remount /system as read-only:
Code:
mount -o remount,ro /

some day ago i change my home adsl router-wifi ap, and i was looking into the wifi setting: there is the possibility to select the bandwitch.
i try to set 40 Mhz in both bands but i note that the phone disconnect itself sometimes so give a try to set 20 Mhz in both bands, the result is no more disconnection.
don't know if is only fate or if there is an issue regarding the 40Mhz bandwitch, or may be is an issue of my router.
this is my wifi network configuration:
-band 2,4 Ghz
-channel 1
-bandwitch 20 Mhz in both bands
-rate auto
-fragmentation 2346 (my router default)
-wpa2-psk
if you are having some problem with wifi try to change configuration if you can.
plese post if this work for you or your configuration.
i also noticed with my arc WiFi would not work properly if i was using mixed mode authentication on my router..
Hi all,
Is anyone having problems connecting to 5ghz bands on their N4?
I reconnected a simultaneous dual-band router that I used while my N4 was on KitKat. It would connect on the 5ghz band without issues, and I could view the 5ghz bands on inSSIDer. I installed the Lollipop factory image and now I cannot view or connect to my router over 5ghz, only 2.4ghz. Setting a different SSID, changing channels and widths does not help.

I'm having the same issue. It doesn't detect any 5 ghz wifi even if I set it to 5 ghz wifi only. I've flashed the factory image a second time thinking that might fix it but it doesn't.
I'm at work now where we have multiple 5ghz networks, and I can't see any of them. Any ideas on what I can do about this? Report a bug somewhere?
I have the the same problem. I've tried high number and low number channels on my Nighthawk using factory firmware default settings.
I solved the issue by reverting to kitkat 4.4.4. I think Google still has some work to do on 5.0.
i've the same problem.... i also thought to revert to KK but dont have the time for it....
i just wish google will fix the 5GHz issue and i wish for black theme (hate this bright white)
Sent from my Nexus 4
i think, the SSID name is the problem?! i'm at work and we have also multiple 5ghz SSIDs. SSIDs without any special character will be shown.
but i have one more problem with wifi. sometimes the phone can't reactivate the wifi module after i used bluetooth in the car. only restart helps
Yeah, I've been having the same issue since upgrading to lollipop.
I remember those issues with one of the older versions of android, but on 4.4.4 all was fine, I could see the networks and connect to them.
Now I no longer see any of the 5Ghz networks.

My nexus 4 (with Lollipop) behaves a bit differently. It does see 5GHz networks when set to 5GHz only, but doesn't see them in automatic mode.
I'm connected to the 5 GHz band on my WiFi AC 2X2 MU-MIMO Router but the link speed is only 72 Mbps instead of the 433 Mbps that I should get on WiFi AC 1X1 Client. The problem is not on the router because my laptop with 2X2 network card can connect at 866.7 Mbps link speed.
When I set my router 5 GHz Mode to 802.11ac only my Mi A1 won't connect to the network anymore unless I set it a again to mixed.
ROM: Stock March update with locked bootloader
Router: TP-LINK Archer C60 V2
5 GHz Mode: 802.11a/n/ac mixed
Channel: Auto - 153(155)
Channel width: Auto - 80 MHz

I'll do a factory reset but now i'm going to select Spanish (United States) instead of Spanish (Ecuador) to see if that works without rooting my device and installing Xposed.

I noticed that my mi A1 has problems connetting to 5GHz networks on certain channels (usually >100). Try switching in your router settings your 5GHz WiFi channel to something like 36 or 40 and see if it helps.
I can connect 5GHz wifi with 200 Mbps link speed by install Magisk modules "WiFi Bonding (Qualcomm)"

I can connect to the 5 GHz network but i can't get expected 433 Mbps link speed with a AC Router instead of that it only gets 72 Mbps (WiFi N).
Maybe try a custom ROMto see if it is a hardware issue or a ROM issue? I have no issues with 433mbps on 5GHz AC.
If you can also try another 5GHz network to ensure that it isn't a compatibility issue with your router, then we can narrow down the possible issues.
Did it ever connect at a higher rate than 72mbps? Or have you only had this phone for a short time? Maybe see if you can find an older stock ROM to fastboot flash to ensure it isn't the ROM that is messed up?

In which channel if your 5 GHz network working?
PD: This is my second Mi A1 because the previous one got stolen from my house so when I bought it the first thing that I did was installing Oreo and then a factory reset. Also I bought the new router the next day so I've never tested it with Nougat.
btw have 72mbit/s on 2,4GHz as well :/ tried on stock and LOS 15.1

In 2.4 GHz it's completely normal unless you set your router channel bandwidth to 40 MHz (not recommended if you live in a very populated area with a lot of nearly WiFi networks) and enable channel bonding on your devices and you'll get 150 Mbps.
I unlocked the bootloader and flashed latest fastboot ROM with MiFlash using clean all and lock, I'm still getting 72 mbps but the WiFi signal has improved and also now I have Mi Drop, Mi Community and Mi File Manager preinstalled. I'll try a custom ROM in this days and I'll post the results.

It's on auto, currently channel 36. I have no problem with 433Mbps connection on 5GHz, being about 20 feet away in another room with 2 walls in between. I can be upstairs in a bedroom, not directly above the router, and still have over 300Mbps connection.
This is running a Linksys EA6900 router with XWRT Vortex/Merlin custom firmware, and Mi A1 running Pixel Experience with Franco Kernel R2.

I'll give Pixel Experience a try if Xiaomi doesn't launch Android 8.1 with Project Treble this month.
Hi,
wifi hotspot on 5ghz band fails to start / still invisibile to other devices.
It works well on 2,4ghz.
logcat shows messages about missing files and various errors when starting wifi hotspot on 5ghz
I'va tried resetting network settings in both smartphone and PC, no way. Already Tried the DUN trick too via adb.
Oneplus 6T - a6013_41_181103 - oxygenOs 9.0.5
Italy - TIM+Iliad
Just me?
Inviato dal mio ONEPLUS A6013 utilizzando Tapatalk
Same here
Edit : ok so I launched a software to analyze my WiFi network and I found something interesting : when I changed my 2.4 GHz to 5 GHz the software find my hotspot for like 1 or 2 seconds and then it disappears.
having the same issue. happend on OOS 9.0.6 and also 9.0.7. really annoying because my old OP3 is working with 5ghz Wifi Hotspot..
having this issue too!
as you describe hotspot on 2.4ghz is no problem, but when I switch it to 5 ghz and enable it, it's not discoverable/connectable....
+1 have the same issue, even not visible on my notebook
currently I'm on:
9.0.12
rooted - Magisk in place - NO twrp
elemental x kernel
problem still exists for me...
In part this is copied from the xiaomi community because no one is responding there.
I have the xiaomi Mi 9 Lite on MIUI 12.0.10 (still waiting longer than 1.5 year on miui 12.5).
If I connect my phone to our WiFi network its is connected to Wifi 5 (AC). But afer some time its goes automatically to wifi 4(N). which is not the intention. Is here a fix for?
Our Wifi network has suppord for Wifi 5 (AC) and is set to maximum performance. If a setting in the network needs to be changed, it won't happen Because I can't access the network settings.
Wifi 4 is slower and consumes more energy....
