2.4 GHz is not working anymore. It has always reliability issues in the past but fully stopped working for the last 3 days. I see several similar post people complaining about the same issue, but still no official fixing to this issue. This is unacceptable. The product has clear quality issues and the manufacturer does not take any action.

I tried literally everything to fix this, but now I just gave up.

I am super dissappointed and will consider to change to a more reliable router (definitely not TPLink).
