Problems with WIFI G7 Plus

2019-04-01, 22:47 PM

Hello, a few days ago I have a Moto G7 Plus and I notice that the WIFI connection is disconnected and reconnected randomly. Is there any solution to this problem? Anyone else have this kind of problems?

Previously I had a Moto X2 and I never had any problem with the WIFI connection of my house.

Thank you

Sorry for my bad English!

Hello marcos1979,

 

Thank you for writing to us, can we quickly try to remove and reconnect to the network. Go to Settings > Wi-Fi >Touch the "network name" > Forget > Reset your router > Attempt to reconnect to the network.

 

Let us know how it goes?

Yes, I already did that and it did not work. In addition, I tried resetting to factory without restoring the system configuration or apps and it did not change anything.
The router is a TP-LINK TL-WR1043ND v1 with firmware OpenWRT 15.05.1 with the patch against "KRACK ATTACK" installed. Today I tried reinstalling the original packages without the patch and I'm testing how it works. The problem does not always appear, it can happen several times in a row in a matter of minutes or it may not happen for several hours.
I removed the "KRACK" patch on the router because I read somewhere that it can give problems with the new versions of android that, apparently, are already protected against this vulnerability. Some "guru" of networks that can clarify something about it?
There are no disconnection reasons in the router's registers, only a re-authentication, in some cases several in a matter of seconds. Seeing how it works with other devices, the router registers the disconnection due to inactivity (when being turned off, for example). But in the case of Moto G7 nothing appears.
At the moment I can not test with another network because I need it to be one in which I can stay connected for a long time and, in addition, be able to access the router's logs to see if it reconnects at some point because, sometimes, reconnection it occurs while in sleep mode and I have no way of knowing except through the logs.
Now I am monitoring the situation with these new changes. If the failure occurs, I will try to upload the router records to inform more about the situation. The strange thing is that this never happened to me with any of the devices that connect to the network!

 

Thanks for your help!

Do not!
I just had the same problem!
This is what appears in the router logs:

Re: Problems with WIFI G7 Plus

I think I celebrated ahead of time ... It just disconnected after 4 hours and a half and on the router only the following record appears:

 

Tue Apr 2 20:07:21 2019 daemon.info hostapd: wlan0: STA xx: xx: xx: xx: xx: xx IEEE 802.11: authenticated

This is an example of what is observed when a device stops responding:

The last 2 line never appears with the Moto G7.

 

Some help?

Thank you!

I do not know why, but my answers disappear. I apologize if they duplicate.

I already tried to erase the network configuration and restore the factory configuration without success.

Attached the router registration.
I was also able to capture an error report on the phone but I do not know how to analyze it.
Any help is welcome!
Thank you!

Hello again. I reinstalled the original firmware on the router and I have the same problems.
This is a screen recording of the problem:

https://drive.google.com/file/d/1K_l2BspICub4yW2RUwOy5k27u_TLlFiZ/view?usp=sharing

My network is WIFI-2013 and, as you can see, it connects in some opportunities.
Any ideas?
Thank you! I'm desperate! I need to know if I request a change of telephone.

 

Thanks!

Hello again. I keep doing tests and deactivating the option "Allow legacy 802.11b rates" in the router I see that it remains connected until now.
Can someone confirm that this is what causes the problem? Or is it just coincidence and can the fault return?
Thank you!

Thanks for the additional information, we want to look further into this, we have IMEI of your device, this can help us investigate and see what's causing the disconnect. Also, kindly send a Bug Report regarding this. Bug Report will collect information about your current device state.

Here's how:
Note: Capture the report right after the issue happened.

1. Go to Settings -> About Phone -> Tap on Build number 7 times on the build number to go into the developer options mode]
2. After the above steps, Developer options will be enabled.
3. Go to Settings ->Developer options -> Enable USB debugging > Toggle On
4. Enable Settings -> Developer options -> Enable Bug Report shortcut > Toggle On
5. Enable Settings -> Developer options -> Enable Wi-Fi Verbose Logging > Toggle On
6. Once the issue is reproduced, Go to Settings -> Developer options -> Click on take Bug Report or Press Power button and then choose Bug Report from the Power down menu.
7. Wait for some time until the Bug Report is collected. It takes around 3 to 4 minutes to collect the Bug Report.
8. Then upload the Bug Report to your personal Google Drive and then share the link to the BugReport on the forums in a reply or via a private message.
9. Provide observations of what you saw happen right before the Bug report was taken. Please indicate the time that you observed the behaviour in local time.

Let us know if you have any other questions?

This may have nothing to do with your problem of losing wifi but I had a similar problem with my security wifi cameras losing wifi. Finally I solved it.

 

My router is connected to an ancient ups whose battery was dead and therefore no longer providing uninterrupted power to the router. I bought a new battery for it. The wifi losses disappeared .

 

If there are fluctuations in the power supply to you router these small split second power interruptions can cause some devices to lose wifi.

 

Add a ups to your router and maybe your problem will disappear.

 

Let me know if this helps.
