Hello @ All

 

Important notice, that saved my life..

 

After reboot of ER605, we waited, til internet connection is available and then JUST switched OFF the OC200 controller.

 

Since then, internet, wifi and lan connection is stable, now for 1/2 hour now... m8be this will help someone.

@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.

 

This looks like the key for me - I am on 5.7.4, but the frustrating thing is the firmware upgrade was offered through the controller software (ie: v5.7.4). I did not go looking for the firmware on the TP-Link website - and it does not look like it is offered there anyway.

 

I can't see a down-load for 5.8.4, so I am stuck with either rolling-back the firmware or dealing with an issue every day. I did find that going into the ER605 properties pop-up and hitting "force provision" does fix the problem - at least temporarily.  The issue seems to be the 2.1 firmware is not taking instructions/configuration from the controller software unless it is forced.... and when leases run out it is not renewing. Immediately after a force provision it handed out IP addresses.

 

I'll wait to see if this has embedded the configuration or whether I'll have to do it every time (or just roll-back the firmware)

 

EDITI can see 5.8.4 is available on the US site - but not yet on the Australian site

  @Fae I loaded the ER605(UN)_v1_1.2.2_Build 20221015 (Beta) a couple weeks ago and am still getting duplicate (actually 4 IP addresses assigned to one MAC address). Is there another Beta build available?

  @trak55 

 

@Fae has abandoned this thread and is not providing any feedback after countless requests. 
 

version 1.2.3 has been released but does not fix any of the existing problems.

It's my understanding that the ER605 V2 is not afflicted with this issue.

I have an ER605 V2 and it is affected by the DCHP issue with the latest firmware.

 

Before I roll back to the previous firmware, I might try updating the controller software because I have read that v2.1 firmware only works with controller software 5.8.4 (I'm on 5.7.x)
