Deco X50-5G V1 Issue after Firmware updated
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, 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.
