Wifi issue - Xiaomi Mi Max 2 Questions & Answers

Hi guys,
ever since I upgraded to Oreo based roms I've been having wifi issue.
i'm still using 8.4.19 dev rom (this is the only rom that gives wifi + fpc working)
My wifi works fine for alot of times but sometimes it just stop loading anything at all and needs to reconnect and when this happens i will need to reconnect alot of times....and if i trigger something bigger to load (like speedtest.net or game download) issue comes back again.
i had wrong firmware flashed and nearly bricked my device before (screen completed blank and couldn't even see any LED indicator on). it took me whole night trying out and finally got it back in EDL mode by guessing alot...
is it possible that i already damaged the wifi unit by that?
or should i try to do line flash again to start from scratch?
any suggestions?

found out it's the hardrock kernel causing it...maybe it's just my mi max 2 model doesn't like it.

No WIFI on boot.....

I have had the CyanogenMod 7.0.2 stable encore installed and functioning on my SD card for quite some time (a few months) without any unusual issues.
Approx. 2 weeks ago, upon powering on, the WIFI didn't come on and I received all types of error messages. Things like com.google.process.gapps has stopped unexpectedly, etc. When I try turning on WIFI, it just says “error”. Airplane mode is off. It doesn't seem to matter what I try....booting in recovery doesn't seem to fix anything. Today, I tried putting the update 7.0.2.zip file on the sd card again and booted into recovery mode. It seemed to run through the setup but once again no WIFI ~ just all of the errors with google.process.gapps, and others.
Once in the past 2 weeks upon powering on, it came up into the Barnes & Noble system which freaked me out. I powered off immediately and when I powered back on it came up with the CyanogenMod guy as it should.
Any and all help would be greatly appreciated as to what I need to do to get my Nook back in operation.
Thanks.......
did you ever turn on the airplane mode even once ? (even accidentally?) -- if yes, there is bug which disables wifi at start-up (but you should be able to start wifi without errors.
Also - OC kernel can cause wifi issues. you need to reflash the OC'ed kernel using recovery mode.

I've done that and also have the same issue. However, I have done several nightly updates since so I wonder if that is the real issue. Frankly, I think I like it better this way. Wifi uses a lot of the battery so I think I like it better with it off by default on startup.

Use Glitch v14, the included has some slight lag and glitch fixed it up. You can also LiveOC which allows for overclocking of the CPU and GPU.
signal
Has anyone found the solution for the gray\blue signal switching? So far as I can tell it is caused by the wifi; whenever I go from mobile network to wifi data, the signal bars go gray. The only work-around has been to switch airplane mode on and off. Would switching to the newly released glitch kernel do the trick?
EDIT: I have found out the Google services problem (gray vs. blue signal) is only happening when I join a network which requires a redirect authentication OR if the power saver is enabled.
Just got this phone and flashed it with - AOKP Build23 by vibranturk ROM
I have been reading for awhile now before I received the phone. Thanks vibranturk for all the development here! Excellent roms!
1) When I start the camera app from app on homescreen and from unlock - the phone goes into a black screen
The camera app worked fine again after a reset (just turning off and back on) but after awhile it does the same thing - black screen.
During the black screen, I can press the home button to return back to homescreen
** Resetted again, and all seems well at the moment and still fine after 1 hour!
2) I am not sure if this is the rom or just my screen. Did not notice it at first when i flashed the rom. Turning on the screen to unlock the phone, ie when the light starts, i get this bright green full screen flash for like a second. It does not happen everytime and no pattern of when it happens either.
Anyone else having these problems?
Can someone please update the 'AOKP thread in Captivate Android Development' with my issues, just trying to help with the development.
For the signal blue/grey thing, Seems like it goes blue for me when i have data signal coming in, either wifi or data enabled - lights up both wifi signal (only if wifi is on) and signal bars blue.
I have power saver is enabled as well.
My only issues so far are: vibrate + sound doesn't work, touch screen is over sensitive on certain games, and sometimes using Swype in messaging doesn't input if app was already in foreground when replying.(can be fixed by minimizing and reopening the app) otherwise it's works great. fast/smooth and great battery life.

[Q] Question about Youtube stutter and Wifi connection issues

Guys i previously had stock v20e ..and i flashed stock v20q using one of the LG mobile update tool hacks i found here.It got flashed successfully. I didnt do a factory reset though.
Now though the phone works well..
1)The Youtube videos stutter a lot, restarting the phone fixes it.
2)Also the pressing the wifi button doesnt even show up my wifi router name to connect.Again,restarting fixes it.
(Both these problems occur after continuous uptime of about 2-3 days without power off)
What is causing this? I bought a dual core phone and I expected it to be much faster.Quite disappointed.
Guys is there any fix to these issues?Do you guys experience the same issues on 20q?

WiFi strength, range, and throughput

Rate this thread to express how you think the Sony Xperia Z5's Wifi performs. A higher rating indicates that it has excellent range, throughput, and signal strength. Like when you're taking a dump in the bedroom upstairs, do your videos have to buffer or do they come through without interruption?
Then, drop a comment if you have anything to add!
problem wifi
i have a router of wimax " bm626 hauwei"
z5 dual connect with it but no internet.
instead i have z3 compact at same time
z3 it connect with it with internet.
why
any one can help?
Did you tried to reset router to default settings? Did you tried to update router to newest firmware?
Thank you for providing this information so that we know how to protect their eyes
Well all I can say is I have no issues with signal strength at all. When my WiFi works fine, the throughput is good too. The problem I am having with mine (on both 6.0 and 6.0.1) is that I lose my WiFi connection every few minutes. What happens is I'll be browsing online and after a few minutes nothing is loading but the signal indicator in the status bar shows a full signal. I have to turn off WiFi on my device, then turn it back on in order for it to keep going. Very irritating. I have many wireless devices in my house, this is the only one doing it. Oh and I've tried using 2 different routers, no change.
Anyone else experience this?
No issue with mine, reaching as fast as 400Mbps near the router. Signal strength works as well as the Intel PCI-E wireless AC7260 cards in my house, so that's pretty impressive. Overall pretty satisfied with the WiFi performance.
I'm using a Netgear Nighthawk R7000 router with a fibre connection, so I guess that's something.

Im having the exact same issue as you... the connection to the WiFi itself doesnt disconnect.. But what is actually happening is that the Device itself seems like it is putting itself in to this wifi sleep state briefly for a minute or 2 and then just suddenly comes back to it's senses (suddenly wakes up and starts sending/receiving data packets which then resumes loading like normal.. and it does this randomly at nonspecific times..
It could happen within a minute or 2 of using the wifi... or sometimes even after an hour or so of streaming (sometimes within 5 minutes of streaming)....
***NOTE***
My Xperia Z5 has custom ROM and Kernel and is rooted with SuperSU with Xposed and busybox installed running Latest Marshmallow 6.0.1 (.224) Firmware..
THEN I suddenly decided **** this, I'm actually going to fix this shi* lol ( you know that moment when you just had enough and finally decide to bother doing something about it, ).. that's the moment I had..
Anyway to keep this simple...
After several hours of troubleshooting, testing and diagnosing , and trying to narrow down, isolate and fix the damn problem causing it to happen, I'm not sure 100% just yet but I may have found the problem and the fix to this IF the wifi "Hanging" doesnt occur anymore after doing some minor editing of the system files. (Only able to do with a rooted device) .
I will inform you guys with my results in a couple of days and hopefully the outcome is good news .. IF not, ill just have to keep trying and if all else fails ill just factory reset the device since getting everything back on to my phone will only take 30 minutes..
Peace!

Awesome, keep us posted if you find anything! I'm looking into it at my end as well FWIW, I have factory reset and even re-flashed the firmware multiple times with no improvement. Just trying to save you time and effort into reinstalling and stuff
Sweet as bro, thanks for the heads up.. Well so far I haven't noticed any dropouts of any sort as of yet. But I still have some things that I am testing.. Will update soon..

Well.. Here i am.. And unfortunately the issues still persisted.. To top it off, my phone decided to start having random moments where it would just restart on its on, even when left idle for a non specific amount of time. Anywhere between 1 and 3hrs.. I started getting really ticked off with it, so I decided to factory reset the device and install the latest (stock) firmware .253 from Sony using xperifirm and flashtool.. Flashed successfuly, applied latest andropluskernel, applied root, and xposed and also debloated the rom.. so far its been little over 12 hours and i havent really noticed any WiFi issues apart from the WiFi at some point tends to almost seem like it lags and slows down briefly and then just loads.. Not as bad as it was on previous firmware .225 .. Overall performance and battery on device seems pretty decent, without Amplify, without disabling any services or any system tweaks of any kind...
So now that I am onthe new firmware and rooted etc... I will as of this point specifically going to dedicate my diagnosticsand testing solely on the WiFi issue and see if I can find a permanent fix this time on the latest firmware..
Will report back soon.. Hopefully what I have in mind works..
(buffer size, WiFi chip power tweaks, WiFi sleep timers, etc etc etc)

Sorry its been a while..
Just been busy..
So far on the recently updated firmware (.253), I have not had any wifi issues as of yet. And it has been fine since my last post...
One thing ive noticed though is that by default the wifi scanning frequency is set to 180seconds by default.. If you can, try and change the interval between wifi scanning and see if that helps at all..

No worries at all, I have too which is why I didn't see your reply for almost a week.
I haven't updated yet to .253, not sure how to go about it so I have been delaying. I've been poking around the forums here trying to see if anyone posted any instructions on how to upgrade if you are rooted on .224. In the mean time I will keep looking through logs and I'll try the WiFi scanning.
The crappy part is I recently turned on the fingerprint reader and I am also experiencing issues with that. Once or twice a day I get "fingerprint hardware not available" and have to reboot my phone to get that functionality back. I see others with the issue and it happens regardless of firmware so it's probably a marshmallow issue.

All good..
Well you're gonna have to download the firmware from xperifirm and flash it via flashtool.. And since you're rooted with 224, you will have to download the new andropluskernel v34 for 253 firmware.. And TWRP custom recovery 3.0.2. specifically for the Xperia Z5. If you need help on locating the files/guides, I can link them to you, since we aren't in the right thread for this topic .. Just shoot me a PM if you need to and ill happily point you in the right direction.

WLAN Problem pls help!

Hello,
I got an WLAN Problem with my Xiaomi Mi 9. Im currently using the newest Miui Global Version and tried many other ROMS, but got almost everywhere a WLAN Problem. My WLAN is like freezed. Im connected but it takes like 1 min until something load completly. The only way to fix it is turning Hotspot on for 5 sec, then disable it, restart the phone and turning Hotspot on again and disable it. Then my WLAN works perfect, until I restart again. I just doesn't understand what is causing this problem. I also tried different ROMS like Xiaomi EU and CrDroid, but I got the same problem. The only ROM that worked without WLAN problems was Pixel Experience, but its draining my battery too hard. Can anyone help me with this strange problem? Btw I already made a thread where I said I fixed it, but the problem came back after 2 restarts.
