Thank you @David-TP,

I haven't checked this use case after the reset, and have already sent my device back to the vendor for a repair.

However I'm not too sure this would've worked, considering that after the reset, the fans still weren't spinning. Therefore I imagine it would only be a matter of time before issues started appearing again, due to overheating.

I have the same problem.

1. Unit overheating fan not running.

2. Data drop, stop broadcasting.  Sometime yes, sometime no. 

3. After reset, fan not running also, unit broadcasting Data internet to some devices, sometime drop or no data at all. Most time show as connected wifi with no Internet.

4. Reset again, same things happen.

5. Mesh Tech off, still the same 

6. Beam forming disable,  still the same 

7. Swith to 2.4 GHz - still the same

8. Switch to auto - still the same

9. Switch to 5.0ghz - still the same.

How to do Warranty In Malaysia?

  @Dokterd0k Same issue here in Malaysia with me Deco X50-5G. Fan seems to have malfunctioned. Just about 2 months old too.
