I experienced the same problem (LAN & WiFi unresponsive from day 1) and I can confirm it’s the tp-link router (likely the custom firmware problem) that maxis provides are the culprit. After changing to my own router, I haven’t had any disconnection problem anymore. Maxis give cheap router with half baked firmware to us and it’s suck big time! I don’t even rant about maxis ‘cukai’ about 10% of our subscribed speed...
