Model: ER707-M2  
Hardware Version: V1
Firmware Version: 1.3.0

I initially configured WAN/LAN3 to be a LAN port. I have tried to reconfigure it as a WAN with IPV4, Dynamic IP (no IPV6 configured) but when I select Connect on the interface it fails, no connection is made, no IP address is displayed. I have confirmed that the same network works without issue if it is connacted to WAN/LAN2.

 

I can return WAN/LAN3 to operate as a LAN port and it provides a connection and works without issue, when set to WAN it does not provide a LAN connection.

 

I previously had a ER605 and I was able to configure those ports without issue, so it seems unlikely to be operator error.

 

Any suggestions as to what is going on?

  @Clive_A I am unsure as to the underlying issue. I "forgot" the original router (605) I was replacing. I adopted the new router, using the workaround with logging into the management page of the unit in Standalone Mode and and manually setting SYSTEM> Controller Settings, Controller Inform URL, specifying the IP address of the controller to allow the adoption to take place. At this point I also set WAN/LAN3 to LAN mode with the presumption I could adjust it later once the unit had been adopted by the Omada controller software.

 

The unit was fully operational with the exception of  if a port was changed from LAN ro WAN the modfied port would not connect to the WAN side equipment and did not obtain an ip address etc.

 

I was able to negociate some addtional network down time and today I :-

a) Forgot the ER707-M2 from the site

b) Did a reset on the unit using the hardware reset switch, pressed for 5+ seconds with power cycle.

c) Entered a new user and password

d) Excuted the adoption failure workaround

e) Re-adopted the unit

 

I was then able to change the ports from WAN/LAN2 onwards between WAN and LAN operation without issue.

  @tda2806 

Are you facing the same issue as this?

 

If you have switched to a new product, it is best to readopt it. Or reboot the system after the adoption.

Do you still have the backup before you change the WAN/LAN port? 

The backup is when the issue exists. We need the original backup before we can locate the reason. 

If you'd follow this up, please reply back and I will notify you how to send the backup.

  @tda2806 Same issue here, I can't get a WAN connection on the WAN 3-6 ports. I'm on 1.3.0 firmware from April.

There are two ways for you to go now.

1. Follow the instructions which is marked as the solution.

2. Provide a backup privately. We will require you to work with us in your problematic environment. A remote session may be needed.

 

This appears to be more of a problem when upgrading from an old controller or firmware, as the stored/synced config seems to be wrong on the router. We need more details and analysis before we can make a conclusion.

  @insomniac Just a quick note, I didn't pursue this further as I didn't have a backup of the non working, refusing to change LAN to WAN and WAN to LAN configuration. Once I got a working configuration that was stable I have left it alone, the old saying "let sleeping dogs lie" came to mind.
