Frequent Connection Drop NBN - TPLINK VX420-G2h Modem

Level 2

Hi Team,


I have recently upgraded my TPG internet connection to superfast and received a TPLINK VX420-G2h Modem/Router. 

Recently the connections started dropping out frequently and reconnects within few seconds. in the system log of the modem i can see the below error everytime the dropout and reconnection happens.


could you please advise how to get this resolved. this is really impacting my business.

Hi @saravanan0610,


There are different types of dropouts that you may experience:


1. Network dropouts, this dropout is caused by a line fault on TPG or NBN's network. Affecting all device(s) LAN/Wireless connected to the modem/router this may require a real-time test and investigation by our Technicians and Engineers.


2. Wireless dropouts, this issue only affects the device(s) connected via Wi-Fi which can easily be fix by doing adjustment to the modem/router's settings.


3. Dropouts caused by ongoing outage in your area. 


In the event that you experience dropouts via Wireless/Wi-Fi connection, we recommend having a read on the following articles:
