Try to forget the network on the Android phone first and reconnect it to the Deco M5. 

 

Besides, you can disable fast roaming, change wireless settings (including wifi name and password) to give it a go. 

 

Try to reboot the phone as well. 

 

Any updates, please let us know.

Thanks.  Have done that (forgot network and reconnected).   Also reset phone and router, re-booted decos, and other fixes I found online.  Nothing worked.

My wife's phone (same Samsung version as mine) getting exact same problem.  Days after update of Deco units (3 x M5 , V1) .  Computers all connecting fine and our 2 phones can connect to router easily - just not to the M5's.

 

Appreciate the help! Cheers

Thanks for your reply. Then please provide the information below so that we can do further analysis. 

 

1. The model number of the Samsung phone and its OS version. 

 

2. The Deco app version. 

 

3. The current network diagram; besides, you can simplify the network--connect the main Deco to the modem only and verify whether the two phones can connect to it. 

 

4. Can they detect the Deco's wifi network? Or they can see it but failed to connect to it? Any error message pops up? 

 

Thanks in advance.

@JustinP 

Hi,

Would there be any error message when Android failed to authenticate

What are the model numbers and operating systems of those Android devices?

Did this issue start just after the firmware upgrade?

Have you added any of these devices to the blacklist?

Thank you very much and wait for your reply.

@TP-Link 

 

Thanks for the reply, Samsung S6 & S6 edge,

Running Android 7 

 

error is can not authenticate

 

No problems with the system before we installed the firmware.

 

brand new system just installed yesterday so no units on any black lists.

@JustinP 

Hi, thanks for the update;

For these devices(Samsung S6 & S6 edgeRunning Android 7+iPhone 12), I guess that they randomly got the error with ‘cannot authenticate’ and could not connect to the internet;

And most of the time, they connect to the Wi-Fi and work fine?

(So, it is more like these devices would drop the internet connection occasionally and reported with the not-authenticate error; )

If yes, how often did this issue occur?
