  @NTWRK sorry to bother you but hope you can post an update. Was it working fine for you since the update? The link is updated now to the latest beta but I don't have time to update and roll back if it goes bad again at this point.

Hello, I can confirm that ER605V2 with FW 2.1.1 works with Omada SDN 5.8.4. Also mDNS finally works.

I first upgraded the router FW and it kept disconnecting, then I updated Omada and the router still was disconnecting constantly. I finally managed to make everything work after I forgot the router from Omada SDN, then factory reset the router, then adopt it again. Now everything looks to work as expected. I didn't test DHCP as I am using an external DHCP server and I am afraid to switch at the moment :)

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

@Hendrics no worries! I installed this ER605 v1 update on January 18 and have had no DHCP issues since this date. After I installed the update I force provisioned the router within Omada then rebooted the device. I've had DHCP issues with the all of the previous beta bullds though with this 20230118 beta they have all been corrected. I have not tested mDNS though the configurations are now available.

After updating firmware 20230130 to ER605 V2 the internet web surfing is very slow.

  @Fae Updated my ER605 v1 yesterday, seems to work fine up till now. I had DHCP issues before but they were already solved with ER605 v1_1.2.2 Build 20221015 beta.

 

I still cannot use mDNS on gateway. Option is greyed out. Is that normal? Can you confirm mDNS will be activated on ER605v1 in a future update? Or is this only available on ER605v2?

  @Fae  I updated my standalone ER605 V-1 with https://static.tp-link.com/upload/beta/2023/202301/20230118/ER605v1_un_1.2.2_20230118(beta).zip yesterday. All was fine until this morning.

 

Duplicate IP address assigned and lost internet connectivity. I did a power off reboot and it's fine for now but the previous beta lasted longer before getting the duplicate IP issue.

Dear @tansuk,

I have downloaded and upgraded my ER7206 to the beta firmware. RIght after that I have ran the AI Optimisation, since that triggered the problem last time, unfortunately, i still had the issue. My devices didn't get IP address until I went to the Network section and click "Save" button without changing anything.

Yes, mDNS will be supported on ER605v1 in the subsequent update.

  @Fae 

Hi
Unfortunately, the issue still exists for me. After the upgrade to the beta I restarted the ER7206, but some devices didn't get an IP address assigned... Back to 1.2.1 at least that works again.

regards

Andy
