UMI Plus wifi problems

alareth1976

Hi,

I have an UMI Plus with these specifics

Android Security Patch Level : June 1, 2016
Baseband Version : MOLY.LR11.W1539.MD.MP.V9.P15, 2016/07/19 17:19
Kernel Version : 3.18.22\rom@91umi.com #4\Thu Nov 17 10:39:53 CTS 2016
Build Number : UMI PLUS.V3.01_20161117

Out of the blue it has started to have problems with Wifi.
Sometimes I'm using the phone as WiFi hotspot for my Android Car Stereo and I noticed that every time I enable WiFi hotspot, once I stop it WiFi won't turn on.
I needed to restart the phone in order to have a functional WiFI, but then it would happen again. After 4/5 times just stopped working and I need to reset phone to factory.
Now happened also when I disable WiFi for a bit. Once I tried to enabled it, it just won't. Go on for 1/1000 second and then turned itself off. So I probably need to reset it to factory... AGAIN!
Even stranger, If I enable WiFi hotspot I can connect to it and it works! o.O

Someone can help me?

thank you

Hi again....

I also tried to activate BLUETOOTH and the problame is exactly the same : Bluetooth goes back by itself to OFF after a quick time !

WHAT IS UMI DOING ABOUT THESE PROBLEMS ??

I have sent emails, but UMI technicians or staff DO NOT EVEN REPLY !!!

Hello to other poor victims of UMI PLUS WI-FI problems ! I just received yesterday my brandnew UMI PLUS and was happy... until I discover the terrible problem with the WI-FI which goes back to OFF very quickly after beeing set to ON.
What is UMI doing about this problem which affects a lot of machines and, as it seems, not only the PLUS model ?
IT IS URGENT dear UMI technicians !
Thanks...

First, update the firmware on the router.

I had a similar issue. I disabled the Standby intelligent power saving option in the Battery settings panel and the Wifi issue disappeared. Also, battery saving is way better since then.

\n\nSame problem, got my UMI Plus E yesterday and immediately faced the WiFi fade-out problem.
Firmware update on the air to the latest official one:
Android Security Patch Level : January 5, 2017
Baseband Version : MOLY.LR11.W1603.MD.MP.V30.4.P12, 2017/01/13 10:31
Kernel Version : 3.18.31\rom@umidigi.com #17\Fri Feb 17 10:14:52 CST 2017
Build Number : UMI PLUS E.V3.02_20170216

...and the WiFi fade-out problem remained unresolved.
Went through all the solutions, got rid of the Russian language as a main display - changed to English instead, that resolved the problem with Battery saver profiles error only (used to pop up every time I tried to turn WiFi ON).
Hard Reset with complete wipe-out helped somewhat, but with furter setting up of the new phone the problem returned.
Home WiFi router TPlink AC750 Archer C20 runs the latest firmaware, still could not hold wifi with this thing on either band (2.4 / 5 GGz).
What else I miss or shall I just demand warranty replacement ?

UPDATE:
Problem seems to be resolved by completely switching OFF all of the battery Smart Controls / Battery Saver - WiFi now runs without interruptions.

Tried this option, did NOT help either....

Hi there. I think that I solve this problem. Go to developer options and turn on " Aggressive Wi-Fi to mobile handover"

Mi Umi también tiene problemas con el Wi-Fi, parece que el problema se ha iniciado con la actualización de Android 7, espero que los desarrolladores arreglen este problema lo más pronto posible, ya que trastear apagando ahorrador de batería o actualizando el no se que no hay tendencias ser nuestro problema si no el de Umi y sus desarrolladores.

Espero respuesta de Umi
