Slow Wifi issue on android 11. - General Questions and Answers

I updated my redmi note 9 pro max to android 11 on june 25th 2021 by a normal OTA update and after that update the wifi speed has decreased drastically on my phone.....the mobile network works fine but the wifi is now at 30-45% of its initial capacity. every other device on my router has the max bandwidth. i reset my phone for like 10 times....but this issue persists....... does anybody else face this? if yes then what can be the way to fix it?

I'm pretty sure your issue isn't caused by the OTA you flashed.
What frequency band is used when you establish a Wi-Fi connection, 2.4 GHz or 5 GHz ?

[Q] CM9 build 14 Low wifi signal

Whatssup guys ? I have installed CM9.1 build 14 for HTC Explorer, it's working fine but there's one little problem, my wi-fi signal is low when I'm not close of the router, In the original htc explorer rom I had very good signal . How do I fix this ?
it just displays that way..otherwise speed is same as stock rom.
This commit: https://github.com/sakindia123/android_kernel_htc_pico/commit/9b0f1c0702e210bdbd1a6b9eeca9fba6cce984c8, might be causing it. Try reverting it, and compile a kernel, and test for WiFi range.
Even though it *might* fix it, battery backup might be directly hit.

[Q] Wifi Bug Nexus 5 Stock(5.1)

Wifi Bug
Hello ?. Nexus 5 (5.1 stock) here. Cm 12.1 managed to fix the wifi problems on Nexus 5? 
The problem that i have is very weird. My wifi signal is full , seems connected to the internet but something is wrong because several times i have not internet access at all. When i turn off the wifi on my Nexus 5 and turn it on this will fix it temporarily. I will flash cm 12.1 with the hope that this will fix it.
I have several devices connected to the same router , only my Nexus 5 has this problem and after the lollipop update. It happens when is connected to other routers as well . I read a lot , i search all over the internet for a solution . It seems a bug on lollipop.Several nexus(lollipop) users have wifi problems. Thats why i am asking if cm 12.1 is wifi bug free. 
Thank you and sorry for my English..
Stock lollipop is god awful. 5.x based rooms aren't much better but you should be able to flash one that fixes your issue.

Stryflx rom need help on some bugs

Hello. I install stryflx 5.1.1 rom v1.5. Yesterday. Its seems very good in using.
I found some problem
1. My xperia L hang 2times only option is to remove battery.
2. On factory reset its doing stuff optimising apps.
3. About phone software update and its below option not working setting forced closed.
4. Internal browser not much worthy.
5. On change pixel density to max menus are going outside of display.
6. Only 3G option not there. Hence drinking battery by switching network btw 2G and 3G. On network manually search not telling which is 3G or 2G network.
Sorry for bad english.
Except above
This rom is very good. I love it.
Waiting for new update.

5ghz WiFi , Sony Xperia E5 , Xiaomi Note 4 : frequency/channel question

I cant post in the xperia forums so ..
I have both the Sony Xperia E5 and the Xiaomi Note 4 on my 5ghz home network and everything is rosey , however , i have a quadcopter ( drone) that has a camera using the 5ghz network , i have tried to connect it to the phones but cannot see the quadcopters camera , it does however appear on my daughters iphone when she scans the WiFi for access points so i know the camera is working it is just that the 2 android devices cannot see it.
I understand that there may be a difference in bands/channels used between countries and that some bands/channels are used/not used depending on geographical location , so , is there anyway that i can "open" the phone in order to be able to see the camera on the drone ? i am hoping that this can be done with software or via a relatively simple method ( i do not understand why the Note 4 doesnt see the camera as it is obviously a global rom )
The channels/bands in question are 149 and 153
Thanks for any information you can provide

Android 10 issues
Ever since i updated my A7 to Android 10 i'm having issues with it. First thing noticed is that internet speed decreased. Second is that i'm unable to connect to wifi with hidden SSID. Furthermore apps - and the phone itself - seem to be working significantly slower comparing to previous Android version. There is NO illegal software on the phone and it is regularly updated to the latest app releases and everything worked just fine & fast until the Android 10 update was done.
As i'm reading, same thing happened to users of other manufacturers phones after Android 10 update (for example Huawei).
Anyone else is experiencing samelike issues?
yes, everything you describe. Same here.
Im back to 9...
Does anyone having problem cannot change camera resolution?
