Updated on Sep. 21, 2022:

 

Remove the 0918 Beta firmware as some users reported it causes CPU spikes issue.

 

Updated on Sep. 19, 2022:

 

Update the Beta firmware and add the latest Beta firmware for ER605 v2/ v2.6,  which have added the fix that Omada Router may wrongly report the clients status to the Omada Controller, causing the issue that offline clients were still shown up in the Controller Clients list, and connected to the Omada Router (instead of the SSID or network). For more details, check this related post.

 

Updated on Sep. 16, 2022:

 

Update the Beta firmware for ER605 v1 and ER7206 v1 with the latest version, which has fixed the recent DHCP failure issue. For more details, please check out the solution post below. 

ER605 ER7206 v1 - DHCP Server May Fail With 1.2.0 and 1.2.1 Firmware.

 

Updated on July 28, 2022:

 

Add the beta firmware for ER7206 v1 and ER605 v2.

 

Updated on July 27, 2022:

 

With the release of the 1.2.1 firmware, we received some feedback that the DHCP Reservation stops taking effect after upgrading to the 1.2.1 firmware, while reverting to 1.2.0 firmware doesn't have the issue.

For example, you've reserved a fixed IP 192.168.0.150 for some clients (including IOT clients, PC, Printer, etc.), most of them would obtain the reserved IP addresses, but some of them wouldn't. The impacted clients may obtain the reserved IP addresses after several reboots on the clients and the router, but after running for some time, the problem occurs again.

 

After further troubleshooting and investigation with our community members @PapyPom, @Riverfront, @Skeidinho, (thank you all so much for your great cooperation!), the R&D team has finally addressed the issue.

 

Available Solutions Updates:

The following Beta firmware can fix the DHCP Reservation issue on both 1.2.0 (or 2.0.1) and 1.2.1 firmware, and the subsequent official firmware will add the fix soon. As a temporary solution, you may install the Beta firmware below to fix the issue, (the beta firmware for ER7206 v1 and ER605 v2 will be provided gradually, please wait patiently).

This Article Applies to:

 

ER605(UN)_V1_1.2.0 Build 20220114 and earlier firmware

ER7206(UN)_V1_1.2.0 Build 20220117 and earlier firmware

 

Background:

 

Omada SDN Controller v5.0 has supported to configure DHCP Reservation for Omada Devices (mentioned HERE), and also support to reserve static IP address outside the DHCP Range (mentioned HERE). Besides, the DHCP issue caused by wrong configuration (duplicated DHCP reservation) has also been fixed completely with the gateway 1.2.0 official firmware (mentioned HERE).


However, we noticed that there are still some feedback on the "Use Fixed IP Address" (DHCP Reservation) issue after Omada Controller v5.0 (check Here for update) and Gateway 1.2.0 official firmware (check Here for update) is released.

 

Issue Description/Phenomenon:

 

Configuring the "Use Fixed IP Address" on Omada SDN Controller for some clients (IOT devices) doesn't take effect. For example, set static IP 192.168.0.150, the client consistently gets a different address after restart.

 

For more details, you may check for the following threads.

Use Fixed IP Address not working.

IP address reservation still not working reliably

 

Thanks for all of your effort to work on the issue.

After further investigation and tests, TP-Link support team has addressed the problem finally.

 

Available Solutions:

 

The R&D team has made a Beta firmware to adapt to the behavior of the IoT devices accordingly.

Welcome to install and verify that it can resolve your issue effectively.


ER605(UN)_v1_1.2.0_Build 20220328 (Beta)

ER7206(UN)_v1_1.2.0_Build 20220328 (Beta)

Note: Please be sure you have read the Beta Test Agreement before proceeding!

 

 [Case Closed]  Update: 

 

The issue has been fixed in the official 1.2.1 firmware, please check for an update from Here.

 

Thank you for your attention!

 

Feedback:
 

Still doesn't take effect for your clients with the Beta firmware above? 

It might be a different case, please don't hesitate to comment below for further assistance.

 

Looking forward to hearing from you for the test results of the above Beta firmware!

  @Fae 

Thanks for the Update

I have just upgraded from 

Model:ER605 v1.0 Firmware Version:1.2.0 Build 20220114 Rel.76871

to 

Model:ER605 v1.0 Firmware Version:1.2.0 Build 20220328 Rel.57418

 

I will give this beta firmware some test

 

Here is some information about my network setup

In addition to ER605, I am also using

TL-SG2008 v3.0 IP Address:10.15.0.7 Firmware Version:3.0.2 Build 20210806 Rel.55686

TL-SG2008P v1.0 IP Address:10.15.0.6 Firmware Version:1.0.2 Build 20210806 Rel.55686

 

Both of these had their DHCP set to none to prevent conflict with the ER605

 

I also own 5 TP-Link Tapo C200 Camera and Some of them will have the static IP problem as described in the previous post

I have configured them with a static IP and every Monday when my ER605 reboots on schedule. Some of the cameras will end up with an IP that is not the configured static IP.

A simple click on the "reconnect" button within the Omada Controler will set it back to normal.

However since these cameras are used for security purposes, manual reset and frequent IP changes render them useless.

Dear @btx,

 

btx wrote

Why is there no possibility to upgrade firmware in omada controller software? I do not have a problem with switching back to original for upgrade, but whole process takes then too much time, instead one would like to flash directly from controller and device should be adopted on next reboot.

 

Sorry that I'm not quite sure if I understand your question right. Are you looking for a way to upgrade the gateway firmware via the Omada Controller? If yes, you may navigate to Device Config -> Manage Device for Custom Upgrade where you can manually upload the firmware by clicking Browse.

Dear @btx,

 

btx wrote

  @Fae Few weeks ago somebody gave me back his tp-link hardware, it included tapo c200 cam's which in fact are the only wireless devices having this issue in the network. He also used P100 (or P110), I did not check if those got wrong addresses (in fact I even did not reserve them in my testing, as there is nothing which one would do like streaming with a cam). I wrote this just for correction, as you wrote that this resolves issues with IoT devices, but from what I can see, the issue is in all wireless devices from strictly tp-link (at least in my tests).

 

Thank you for the information. I actually did test the beta firmware with a few TP-Link smart home devices (I think they are also IoT devices) and it proves to work. If you get different results, please feel free to report here.

Thank you for your kind feedback. This beta firmware should be able to fix the issue, please take your time to verify it.

 

Kind note that the MAC address is not something we need here. I'd suggest you edit your reply and delete the product MAC address as it might be sensitive private information. Thank you for your attention!

  @Fae 

Ok, first after the patch all seems to work well.

 

I upgrade from:

ER605(UN)_V1_1.2.0 Build 20220114 Rel.76871

to:

ER605 Version:1.2.0 Build 20220328 Rel.57418

 

My setup is:

TL-SG2210MP v1.0      1.0.2 Build 20210806 Rel.55686

EAP265 HD(EU) v1.0    5.0.4 Build 20211021 Rel. 57494

 

After 10-11 hours i face a internet disconnect and after that i can't connect to internet. I try many times to reboot my  605 and my ISP modem(DSL LINE works fine tested with other router) but nothing. I manage to solve the problem only with (down)grading to stable version Rel.76871 but with the same problem for my cam Tapo C100.I also try to manual connect (PPPOE) but same result .

 

In mean time and when everything was still works with beta firm i try to manually restart,  reboot, power cut my Tapo C100 and everything works fine no change IP.

Thank you Fae and TPLINK !

I can confirm that the DHCP IP address reservation functionality issues appear to be resolved after flashing the following firmware to my TL-R605 v1.0 router :  ER605(UN)_v1_1.2.0_Build 20220328 (Beta)
 

OmadaLinux v5.13.10 R605 V1:1.3.0 - Build 20230511 R.51317 SG2008P V1:V1.0.8 Build 20230602 R.73473 SG2008P V3:V3.0.5 Build 20230602 R.73473 3 x EAP245 V3:V5.1.0-Build 20230104 R.79433
