WiFi internet speed dropped considerably after firmware update. Although wired connection is working fine. Also not able to downgrade firmware build to 1.4.1. Any suggestions?

  @Orais 

Thank you very much for the feedback.

It is suggested to install the beta firmware here to see whether it helped:

By the way, can I have more details about the wireless speed issue?

How much wireless speed you can receive before and after the firmware upgrade?

Have you enabled Device or Scene QOS?

Wait for your reply and best regards.

Thanks!  @David-TP 

 

I installed the beta firmware as you suggested and so far my speed has been restored. I have also turned of Qos. Seems stable so far. 

 

Regarding your questions on speed, my home connection is a 40Mbps, and after the firmware upgrade (1.5.0 Build 20240311 Rel. 66190) it dropped to 0.2Mbps at best. Although the _guest signal and wired connections were working as usual. 

 

Should I turn off the Automatic Firmware Upgrade setting, until a patch has been released to activate Qos again?

 

Thanks!

Thank you very much for the update.

I think you can turn off the auto firmware upgrade for a while until a stable official 1.5.0 version is finally released later.

Best regards.
