I installed Lineage OS, the problem didn't show up anymore.

installed all the apps previously installed, everything still working fine after a week.

Redmi Note 9
Hi, I plan to buy Note 9 pro, but this wifi problem prevents me to do so. Is this issue still present on 11.0.11 or only fixed for some people?
Im on global MIUI 12.0.2 now and havent experienced any wifi related issues in a long time now. ( and I spend the vast majority of my time working at home connected to my home wifi.)

If there was a work around software patch implemented, ive not noticed any negative impact of it in terms of connection/reconnection or battery life.

Im on miui 12 issue still happens. But iv said this years ago its a hardware issue and never will be fixed.

Can you please share your access point settings or logs from your access point, so we can try to help you?

Probably it's something about your AP settings or you have a defective device, since it was finally fixed from version V11.0.7.0 on QJZMIXM

not the access point, its happening on multiple ones. looks like xiaomi getting the huawei treatment now so serves them right for putting out dodgy hardware.

    Can you share with us how you did the hack in MacroDroid? It'll be very helpful :)
    Done, it restart the wifi every 15 minutes. You'll didn't notice it

    seems to be solved with 11.0.3 on my phone

    Hey,

    it seems to be solved with MIUI 11.0.3 on my phone (fingers crossed).

    Here is what I did:
    Because of the fact, that there is no other OTA update per default than 11.0.1 for my phone (yet), I had to download it from
    https://c.mi.com/oc/miuidownload/detail?device=1900378 (can't link it due to "new user status")
    I live in germany and thought I should have a "Redmi Note 9 Pro global" Rom, but the Update process told me about "a different radio version". So I took V11.0.3.0.QJZEUXM which is for the EEA Version (no idea what EEA stands for; bought my phone directly from mi.com/de).
    To install it, I had to go to "settings - my device - system-update" and klick the "11" multiple times (like 5-10 times), since it says something like "additional update options enabled". Now you can klick "the three dots - choose update package" and choose your downloaded file.
    After the system checked if it's the right one, you can install it by a klick.

    I didn't root my device or something like that, the updateprocess is (as I believe) identical to an OTA Update. The packages is directly from mi.com, so I wasn't afraid of installing it ;)

    I'm running this version since yesterday afternoon, with no Wifi issues so far (fingers crossed again) an no forced reboots.

    Hopefully this may help you ;)

    greetings

    In these days i were in contact with xiaomi assistance for this issue. I passed them several logs and did some tests. Today they said me that it is ready a test version that solves the problem and they will pass me it in these days

    Is root necessary? Thanks for your work.
    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.

    The dirty hack I've posted above hacks it. To be clear, not a fix... very much a hack.
