Somehow my Router's wireless 'light signal' remain shut after i switch on both modem + router many times. Any idea what happened? Plus i couldnt connect to the internet (LAN) even when the all the remaining 'light signals' remain switched on (yellow)

D-link or default (white and orange)

Hmm i never disabled such settings before. It can be disabled automatically?

Anyway guys, i sorted it out with TM Unifi through phone-call

Here's the cause for it:

The router experienced sudden power shutdown or shortage which caused it to go back to default status (all lights still switched on except wireless light)

Basically, TM unifi reconfigured my LAN network to my PC from their side and lastly after i logged into my pc, they taught me on how to reconfigure my wireless network configuration (d-link 'webpage')

Thanks for the feedbacks from y'all!
