Why doesn't my FWA505 return from Cellular mode to Ethernet

torstax

I have configured my FWA505 to use Cellular WAN as backup for my Ethernet WAN.

If I unplug my Ethernet WAN cable, the FWA505 switches over to Cellular WAN as intended.

But when I connect the cable again, the FWA505 refuses to use it until I turn power off and on.

I use the system info on the admin home page to see what WAN is currently used (see picture)

My configuration of WAN backup is exactly as in this post:

Noted: the option "The Destination for Connection Check" need to set up the destination that both cellular WAN and EtherWAN can ping.

How to get FWA505 to accept the Ethernet LAN when it comes up again?

Hi @torstax

When you reconnect the Ethernet WAN, the FWA505 should automatically switch back to Ethernet WAN within a few seconds. However, the WAN status displayed on the web interface under Homepage > System Info might take some time to update. Additionally, a refresh of the web interface may be required to see the updated status.

Could you try refreshing the web page and confirm if the status updates correctly? Let us know if the issue persists, and we'll be happy to assist further.
