Router stops working, needs disconnect and reconnect - not reboot- to restore
I have been encountering a recurring problem with a hotel network using the ER7206 router on an Omada controller.
The network is [Provider’s router] -> [ER7206]-> [Omada switch and rest of network].
What happens is that the WAN connection stops working, so there is no internet connectivity. Inside the network continues to work. From the local Omada portal, the router appears to work correctly.
Internet continues to on the provider’s router and rebooting the provider's router does not help.
If the ER7206 is rebooted, either by unplugging the power or from the reboot option on the Omada portal, the connection stays down.
The only solution is to find the device on the portal, disconnect the wan connection and then re-connect.
A few weeks ago I had a similar problem with this device but that time some websites continued to work. This time everything stopped working.
Has anyone else encountered this problem before or have a solution?
