Tp Link R470T+ only connecting to Backup WAN in failover mode
I have 2 Internet connections : 1) FTTH and 2) 4G (via ethernet on separate router).
I have configured the TL-R470T+ router as a failover wherein the backup wan shall connect when any primary WAN fails.
However, when both the WANs are available the router persistently connects to WAN2 (Backup) even though the Primary WAN is healthy.
The config was working well till some months ago. I have recently changed the backup WAN router and only since then the issue has happened.
I have verified all the config also as per some references on the internet, still no luck.
Please advise any solutions.
Thanks.
Tanay.
