Firmware Version: 1.2.1 Build 20250413

After upgraded the firmware to 1.2.1 Build 20250413 , my Deco X50-5G V1 often loss connection.

5G signal is full 100%

Before the upgrade it was fine at all and could watching Youtube videos without problem.

Now connection become unstable, cannot open fast.com like usual to test connection or open Youtube videos without lagging.

 

How to downgrade the firmware or reset back to factory setting with the first time origin firmware?

Hi, may I know your SIM ISP?

Have you tried to reset the Deco X50-5G once after the firmware upgrade?

 

Please refer to the following suggestions:

If no further improvement, please send an email to support.forum@tp-link.com with the following details:

  • The screenshots of the internet settings/WAN IP addresses before and after the 5G outage.
  • A screenshot of the Cellular details after clicking "Additional information"

Thanks a lot.

Best regards.

Hi, welcome to the community.

May I know your SIM carrier?

A new firmware 1.3.0 was released a few days ago. It is recommended to update to the latest firmware version to see whether it helped:

Deco X50-5G(EU)_V1_1.3.0 Build 20250724

 

By the way, have you seen Deco turn red during the disconnection?

Wait for your reply.

Best regards.
