Look at the default interface if all the ports are enabled.

I had something similar on the ER8411 after upgrading to 5.14.?? I don't quite remember the version after 5.14, the problem was that one of the ports on vlan 1 was removed from the default lan interface. and since the default interface cannot be modified, I was also unable to enable vlan 1  on that port.

what I had to do was delete the router from controler and readopt then all ports was enabled..

default inerface looked like this and did not allow to be changed.

Hi,

Thank you for your suggestion.

You're right—I can't modify or remove LAN interfaces on the default LAN. Unfortunately, I'm unable to reset the router and readopt it, as I am not on site. If I reset the device, it will lose all ISP configuration, and without an internet connection, I won’t be able to remotely access the router again.

Was there ever a resolution to this? 

I am running:

• Software Controller 5.15.6.7 (Release Candidate)
• ER707-M2 v1.0 1.2.3 Build 20240822 Rel.52946
• SG2210MP v4.20 4.20.4 Build 20241104 Rel.40492

If I try and check "[] WAN/LAN3" for my VLAN 1 LAN Network, I get the Error: "The interface of Default LAN cannot be modified."

Thankfully I have an open LAN port I can use already, but this is not great...

Current settings:

When I try and check WAN/LAN3 for LAN Network and click Save:

  @daubstep 

yes it can be fixed in two ways,
1. delete router from controller and readopt it
2. change the interface to WAN and then remove WAN again.

  @MR.S Thanks for the reply, it's good to see there is a workaround... it's unfortunate that most workarounds require nontrivial network downtime - I'll have to wait for off-hours to try this:

😭

Modify the WAN ports?
Modification of WAN Ports will reboot the gateway.

  @daubstep 

set aside an hour for the job. it has to be done twice since you have to remove WAN again to enable LAN and the router is not that quick to boot
