My office have been using Maxis for more than 6 months, but for the last 1 month, been getting internet disconnection intermittently. Maxis technician came and changed the router, still happened... Then TM technician came and said their line is tested ok up till the modem.

Then I just noticed today when it happened that the lan port LED indicator where we had cable connected devices still blinking after i disconnected the cable. This implies that the router hanged, causing the internet disconnection....
