PLEASE PLEASE PLEASE help me out with this because neither the TP-Link Technical Support on call could resolve this (despite 5 calls that I made), nor could the email support resolutions resolve this issue. They have been giving same responses now - to no resolution.

So I have tried this with 2 Archer C20 routers and still saw the same issues. The issue is:

My current setup is-

I have a PPPoE connection setup.

Service name specified has already been put in the router's Network page.

Connection always on

Issue:

When i restart the router (remotely from the router config page or from the hardware itself),

2 out of 10 times (or someetime more than 7 out of 10 times), the WAN light turns Orange and the internet does not work, and neither does the WiFi.

I have tried:
Changing the connection type to - Connect manually WITH Max Idle Time: 0

Using the updated Firmware where the dropping of Internet was more frequent and it was determined entirely a Firmware issue.

Downgrading the firmware helped reducing the multiple disconnections TILL THE TIME the router is not being rebooted. After the reboot, the issue persists as mentioned above

NOTE: This issue was not observed when I had my older router setup: Model - TL/WR-740N
