Hii. I updated to the latest firmware like a week ago. First week everything seems fine. Today i noticed my speed arent going above 20Mbps. I tried placing another sim, same situation. I tested both sims using my Phone, easily achieve 200mbps+-. I will downgrade back and check again if the speed changed or still the same

The new software is not available to automatically update yet.
You need to download it from the TP-Link website and install it manually.

Just noting that I experienced the exact same issue - once upgrading firmware my speeds were awful, even when trying to fix the network bands it didn't help. I tried to downgrade the firmware following TP Links advice but the router ended up being bricked - luckily I was still in warranty and TP Link helped, I have since received a new router but not upgraded the firmware. Came to this forum today to see if there was any update on stability but I think I'll stick with older firmware for now..

@David-TP I updated to the latest version and everything seemed to go pear shaped. I was unaware that QOS became enabled and restricted upload and download speeds to 0.1mbps. This meant that while I was connected to the internet it was impossible to download anything. Disabling QOS resolved the issue.

Hi, thank you very much for the feedback. It would be very helpful if other users run into a similar issue.
I did see this feedback occasionally that QoS was automatically enabled and set to 0.1( or a lower number) Mbps download/upload. It seems not to be related to a specific model.
I'll note it down first and report to the engineer for further confirmation.
Thanks a lot.
Best regards.

@David-TP When will version 1.2.1 be available as an regular update via Deco mobile app? From my understanding now it can be installed via web UI only. Particularly, I'm interested in information regarding Czech Republic region. Thank you for the answer.
