You have to edit a file called "WCNSS_qcom_cfg.ini". On Mi 8 SE its located in root /vendor/etc/wifi.

Just set BandCapability=2 and restart phone.

Here is an excerpt from the Mi Community very fresh from today regarding the Note 9Pro/S. They seem to be working on something concerning the Qualcomm modem. Maybe this is our current problem.

Weekly Bug Fix Report:

- Random reboot Redmi note 9 pro/S V11.0.4.0.QJWINXM Still under investigate

- Qualcomm will release CR for Modem crash issue

Hello, I have a redmi note 9S with the same issue. I'm in Italy on a MIUI Global 11.0.6 and as soon as I put the phone to sleep wifi says it's still connected but it doesn't work. The only way to make it work again is turning wifi off and on again.

I have a g wifi network. I also gave the phone a static IP address, I tried disabling the wifi assistant and changing the phone region, no luck.

The xiaomi italian assistance didn't really understand the problem and I'm losing hope that this message ever reaches the developers.

[Redmi Note 9S / Note 9 Pro (Indian Model) Question] skezza:
Nope and I've switched to using MacroDroid now as Hotspot mode isn't supported in Automagic but works fine in MacroDroid (different reason). So both are good for this.

Unfortunately, the update seemed to work for 2 days but was a false positive. It happened again today. I tried a different experiment, I used Allcast to torrent and play a film at the same time (cool feature on Allcast) and it worked fine despite sleeping for 2 hours. It's definitely some bug in the low power or low usage mode. I am sure they'll fix it soon.

For now the Automagic/MacroDroid hack fixes it.
[Redmi Note 9S / Note 9 Pro (Indian Model) Question] cimdrap:
It's a generic advise, not resolve the problem for sure. They have to fix it in the firmware

[Redmi Note 9S / Note 9 Pro (Indian Model) Question] cimdrap:
Ok there is a little problem: i was tired waiting for a solution from them and installed the Xiaomi.eu.

Just to see if the problem persists with another rom and i just noticed it does.

But now the question is: what should i do when the assistance will give me that test version? Should i flash over?

I want to avoid reflashing the global stock setting again all my stuff and maybe relocking my bootloader
[Redmi Note 9S / Note 9 Pro (Indian Model) Question] lucadica92:
Probably it'll be an addictional package, so it would be better to be on stock firmware.

Relocking bootloader should not be necessary.
[Redmi Note 9S / Note 9 Pro (Indian Model) Question] Zasnizas:
We don't know yet what causes of the WiFi issue here. Maybe it because of rom bug or hardware problem. For me I have used my RMN9S more than two weeks now and I don't have any issue with WiFi, no problem at all. So I don't know whether this is because of bug. Hopefully xiaomi can further investigate this issue and solve it

---------- Post added at 04:26 PM ---------- Previous post was at 04:22 PM ----------

Yes, I think there are some devices with this problem. I've also a problem with an Internal Error while switch the camera or change 1080p 30fps to 1080p 60 fps.

I think that Xiaomi will see all these devices come back very soon.
[Redmi Note 9S / Note 9 Pro (Indian Model) Question] Fandi901:
Hello everybody,

I have the same problem.

Here in Germany are special routers from AVM that FritzBoxes have.

I also tried a Fritzbox, and tried pretty much everything, but the error remains.

Yesterday, however, I found a clue.

The Fritzbox offers guest access, which I used for some time without encryption, and so the RN9S has not failed for a long time. In the forum androidhilfe.de this has already been confirmed by someone else.

We normally use WPA2 encryption in Germany, since using the wifi externally is legally problematic.

At my workplace I have open wifi and there are no problems either.

Other routers are of course also affected, but the Fritz boxes all have this problem and these boxes are very common in Germany. Without encryption, this is also not a good option.

You can do it for a test, but it shouldn't stay that way.

Can anyone pass this information on to a Xiaomi employee.

Greetings,

Andreas
[Redmi Note 9S / Note 9 Pro (Indian Model) Question] ov2rey:
Relax. Let's wait for the firmware update to fix the wifi bug... Did anyone test other phone with 720G processor also have such wifi issue?
[Redmi Note 9S / Note 9 Pro (Indian Model) Question] Naroyas:
Thee we have a little Problem. The only other phone out there with an 720G is the "realme 6 Pro", but it has no global release at the moment.
[Redmi Note 9S / Note 9 Pro (Indian Model) Question] Fandi901:
There is probably only a second device from Realme with the 720G. This is not marketed here in Germany. So the device is not particularly common here.

The Fritz boxes mentioned have a very high market share here.

The manufacturer is in Germany, I do not know if these boxes are offered worldwide.

So it will be difficult to find someone who has this realme smartphone and a Fritz box.
[Redmi Note 9S / Note 9 Pro (Indian Model) Question] thriller76:

It seems to me that things have changed.

The device is still logged off after some time, but then reports back again within a few minutes.

Before the update, I tested the guest access of my Fritzbox: Without encryption there are no failures, with encryption they are back.

Why obviously? It's not uncommon for UMTS and WiFi modems to be coupled into one module supplied by a single vendor.

it was only when I woke it up that it went online again, but now automatically.

So unfortunately it is still not a solution.
[Redmi Note 9S / Note 9 Pro (Indian Model) Question] Naroyas:
The strange thing is that the phone still receives the identification of the router, but can no longer send anything.

I tested it with Tasker. I can trigger a ping, which is only done when the phone is connected to my router. So the phone registers the packets from the router, but sending packets to an IP in my network is not possible. Means download is available, but there is no upload anymore.
[Redmi Note 9S / Note 9 Pro (Indian Model) Question] DGP_Maluco:

[Redmi Note 9S / Note 9 Pro (Indian Model) Question] skezza:
Someone rightly pointed out earlier that the WiFi seems to jam in an upload mode. You can even see it once jammed with a single arrow facing up.

Now here's a strange one... I started looking at the options last night and disabled MacroDroid. I toggled WiFi assistant on. The last time it crashed, it disconnected and reconnected instantly. Has been fine overnight as well.

I wonder if the entire modem crashes and this is a dirty fix by Xiaomi.
[Redmi Note 9S / Note 9 Pro (Indian Model) Question] terry_mccann:
Well....interesting problems. Waizing for our 9s any minute.

Guess if I will have that problem for the time being I will use the freeware HostedNetworkStarter and create wifi access via an old laptop until it is fixed.
[Redmi Note 9S / Note 9 Pro (Indian Model) Question] ConradB:
A suggestion to the eager testers among you.

Turn on the mobile hotspot on a Windows 10 computer / notebook and connect the 9s to it. Possibly it works.

Simply tap on the WLAN symbol on the bottom right of the display and switch on the "Mobile hotspot" menu that appears.

A right click on the small tile brings you to the setting options.

No mobile data is required for this function, the computer can be used normally while the hotspot function is active.

[Redmi Note 9S / Note 9 Pro (Indian Model) Question] Naroyas:
not in StandBy. only when I turn the Display on

---------- Post added 3rd May 2020 at 12:29 AM ---------- Previous post was 2nd May 2020 at 11:38 PM ----------

I have found something very interesting in my attempts today to find the problem. If the error occurs then the upload is not really broken. I can still see all other networks an can instandly reconnect me to any other network without restarting the WiFi of the phone.

Together with the facts that when you open an unencrypted guest WiFi with the same router, the bug does not appear and in some casec you can skip the bug with an repeater also I have no problem with the WPA2-PSK (AES) encrypted WiFi in my Office, there could be a trigger for the bug.

This leads me to the conclusion that the reason lies in the type of encryption. The encryption for the newer FritzBox devices is WPA2-PSK (CCMP) which is an advanced Version of WPA2-PSK (AES) and you can't change it in this devices. All the other devices, that I have found, where the bug does not appear have the WPA2-PSK (AES) encryption.

So this could be the key to solve the bug. Maybe the encryption service of the Note 9S stops working properly in StandBy after some time and the WPA2-PSK (CCMP) key can't be generated.. What do you mean? Can this be?

So yesterday I contacted the German Xiaomi Support chat, and the guy I was talking to admitted that the problem's known and that they are working for a fix. He couldn't tell me when it's going to be fixed, though, but he mentioned that MIUI 12 is going to be released mid June, and that it has highest priority and should be fixed before the other update gets rolled out.

Just a bit confusing that some people were told it's an unknown problem, too - support these days, huh? ;)

Unfortunately using WiFi via an access point doesn't solve it for me. My AP is an old Belkin F7D4302 running DDWRT using the 5GHz band.

Hope there's a fix soon.

May be it will work if you changed the WPA Mode from (psk2+ccmp) to (psk2+aes) or (psk2+tkip) as others suggest , I am using gargoyle/openwrt and can do this using WinSCP or Putty SSH , so may be you can as well for DDWRT , using the same programs or the GUI .
