I am one of the users that is not experiencing the DHCP issues but wants to know what exactly is special about the affected setups.

  @Fae 

I received a notification that Firmware 2.1.0 is available for ER605 V2. It said that it is adapted to Controller Version 5.8.4, I was still on 5.7.4 because 5.8.4 is Windows only as far as I could find. I installed the firmware and everything went sideways. My whole network is down, I could not downgrade the firmware inittially. I had to create a new controller on Windows (5.8.4), migrate the Router and then I could downgrade. Now I am working on migrating it again back to the initial controller. Any update on when 5.8.4 will be available for Linux?

 

@everyone

If you do not have a Controller on Windows qith 5.8.4 version, do not upgradeyour ER605 V2 to 2.1.0 until you get the 5.8.4 version of controller.

Current Setup: 1x ER605 v2.0, 1x TL-SG3428X v1.0, 2x TL-SG3210 v3.0, 1x TL-SG2210MP v1.0, 2x EAP670(EU) v1.0

  @Adandu 

I'm on linux controller 5.7 and upgrading to the gw fw 2.1.0 went just fine, something other than the controller version is the issue in your network I reckon.

  @Adandu network is still running, but router is jumping between "adopting", "provisioning", "configuration" and "connected" all the time. Also running Omada on Linux.

  @Loopo I have the same problem/loop. Omada 5.7.4 (linux) and ER605 v2.1.0. My network is also running. 'Clients' is empty. Port information (connection speed etc) is grey/not working. Downgrade won't work.

  @Adandu I've got the same setup as you.  At first, my router wouldn't upgrade...kept throwing an error about not being able to download the firmware.  I rebooted my router then the upgrade went off without a hitch.  Everything is running smooth at this point for me.  Sadly, the new firmware doesn't seem to include a lot of the future features mentioned in the Windows 5.8 controller release notes.  The router release notes make no mention of Wireguard, DNS proxy, or many of the other features.

  @DannyZ I replaced my TP-Link with a Netgear AC1450 and flashed it with dd-WRT from FlashRouter. Picked it because I am  small office home office and need stability and it's old tech. Happily paid $100 USD for them to remote in, set it up, and provide 3 months support  Have had one event when I neglected to log off the router for a PC reboot. Couldn't access it through wire or wifi. By the time I had the second email from  FlashRouter I had rebooted it. Lost 4 of 5 Unifi AP I had to hard reboot and re-adopt. Really hoping this was a one-off event.
