Same here, I'm on 1.6.7 and my Deco X50 (1.0) tells me I'm up to date. When will 1.7.1 be offered directly from the app?

  @JanRekenaar 

 

Updates are pushed to the app by region and mac address so not shocked you see it on the site and not in your app yet but as long as it for your region and hardware version its ok to download 

Need help with the Deco app, setup, Ethernet backhaul, network switch or rolling back firmware? Router or AP mode? https://community.tp-link.com/us/home/forum/topic/699816?page=1

  @osexpert New router, same problem.... Seems google tv's and the likes are whats dropping the most. I tried the old Zyxcel from my isp, actually its stable, but slow. I have ordered usb-c to ethernet adapters for the google tv's. Annoying.

  @David-TP  DOH/DOT disabled. And it was always green and says everything ok. I tried the latest 1.7.0 as well. But the wifi disconnects persisted. Specially bad with Google TV (I have several). Even tried disable beamforming. But I gave up and they are now binned. I think it may be a hardware problem because they were working fine in the beginning. But I have a recollection that Qualcom/Atheros was notoriously bad at wifi becoming worse over time, and possibly all wifi chips they make (still) are junk. So this time I went with a Broadcom powered router, hoping it will be better. Thanks.

  @osexpert 

Hi, welcome to the community.

Have you also configured DOH/DOT? if yes, it is suggested to temporarily disable this feature to see whether it helped.

Have you ever noticed Deco turned red during the disconnection?

If there is an ISP router in front of the Deco X50, it is also suggested to set the Deco into Access Point mode: 

How to set up Deco to work in Access Point mode

 

And if you'd like to spend a little more time and update to 1.6.7, I can forward your case to the senior engineer for further assistance.

Wait for your reply.

Best regards.

  @X50problem  massive problem with 1.6.7 even after disabling EasyMesh. I had two x50, but removed the satellite and only main unit left, but problem persisted. Wifi drop all the time. Wifi speed degradations. Some web pages can not be reached, even on wired. Now downgraded to 1.6.1 and its better, allthou wifi still loos3s internet at times, but a lot less often.

How hard is it to create a wifi router that is stable? Almost impossible, it seems. I guess the future is 4g/5g, its actually much more stable than any wifi I have ever used. Thanks.

Hi, thanks for the notification.

I was told that only the US account ID doesn't have EasyMesh on the Deco APP. For other regions' account IDs, I think it should be fine.

Best regards.
