Deco M4 issues after firmware upgrade
Deco M4 issues after firmware upgrade
2022-05-09 08:39:37
Model: Deco M4  
Hardware Version:
Firmware Version: 1.5.4 Build 20220113 Rel. 38349

I have three M4 Decos that were working fine, last week i saw a firmware upgrade in the app so i did it now the firmware is 1.5.4 Build 20220113 Rel. 38349 and the nightmare started:

 

- wifi drops constantly like every couple minutes

- sometimes even wired internet stops for anything from second to minutes

- network optimization said that wifi is congested then it optimized it but problems started again after some time

 

I have tried to restart all the Decos it did not change anything.

 

Is there a way to revert to previous firmware? or any other way to fix this nightmare

  @Vesparion 

Thanks for the feedback.

It could be reverted back to the previous 1.5.x version(not below 1.5.0) via web UI manually.

But since 1.5.4 is the latest version, I wish you could wait for a while and help me get some information first:

1. Will you see any Deco turn red when the internet is disconnected?

2. Please save the system log when the internet is disconnected before a restart.

Best regards.

The deco i'm near by in the office is red when I went upstairs to see the main deco it was yellow by the time I got there.

 

How do I upload the file? the option in the post says failed to upload.

 

below the log file via google drive for a disconnection event that happened around 10 minutes ago

  @David-TP @TP-Link I have exactly the same experience as you described after the update. Wireless and wired connections seem to lose internet connection and far from stable. Going back to previous firmware.

  @Fellnas 

Welcome to the community.

I see your Deco M4 is on V3 and 1.5.1 is the latest official firmware.

1.5.4 is for Deco M4 V1+V2 and your case might be a little different.

Would it be possible to start a new thread here with more details about your current issue with Deco M4 v3?

 

Thank you very much.

Best regards.

My issue was fixed by downgrading to 1.5.2 firmware, all works fine now after the downgrade.

  @Vesparion I had the same problem with the latest firmware (with v2 Decos). Rolling bact to 1.5.2 Build 20210916 Rel. 56193 was the solution.
