EAP245 V1 not working again
EAP245 V1 not working again
2019-09-15 17:10:50
Model: EAP245  
Hardware Version: V1
Firmware Version: 1.4.0 Build 20180323 Rel. 32551

We have several EAP115-wall, EAP225-wal, EAP225, and one EAP245 on a CentOS-Omada-Controller (3.2.1)

After half a year we had the first Problems with the EAP245, TP-Link told us, that there is probably a Hardwareproblem. After a replacement the EAP seamed to work.

Now there are again Problems with this specific EAP.

 

Just this EAP disconnect periodicaly from the Controller accessing it directly is refused by "System is initializing,...".

After some hours or a restart it connects again to the Controller but is unable to get a proper WiFi-Channel. The Channels for 2.4 GHz and 5 GHz are shown in the Controller as "--" or with a high value.

The "locate" function is also not working, but that's probably caused by the old firmware.

 

We moved the EAP from the TL-SG2210P to a TL-SG3424PV2 to make sure, that no Powerproblem cause the troubles. We also reset the EAP several times and reinstalled the Omada-Controller in a fresh CentOS without any result. Actually the EAP is directly connected with a 2m CAT7 Cabel to the same Switch, where the Omada-Controller is connected.

 

Is there anone who has also Problems with the EAP245V1?

Is there anything else we can try to make the EAP work stable?

You mention the "System is initializing,...", do you mean you cannot adopt the EAP normally? Could you please describe the issue more detailedly?

 The channels for 2.4G and 5G are shown in the Controller as "--" or with a high value, please upload a screenshot about it.

@forrest 

Sorry for the late reply.

 

After a reset the EAP can be adopt as usual. (With or without forgetting it in the Controller)

It seams to work, and change the state in Omada from "Pending" to "Provisioning" to "Configuring" and then to "Connected".

No Channels are assigned

After a while it loose the connection to the Omada. That means:

- In the Omada the EAP is listed as Disconnected

- The login at the Webfrontend of the EAP is not blocked anymore (no message that the EAP is managed by Controller on signin)

- The EAP is still present in the network under the given IP-Adress but on the login-page of the EAP (not Omada) the message "System is initializing,..." appears

 

After just reboot (not reset) the EAP it also reapears in the Controller with the same behavior. "Provisioning" -> "Configure" - > "Connected" -> "Disconnected"

Could you please send us the backup file of the configuration? 

By the way, as you said, only EAP245 V1.0 has this problem. EAP225, EAP225-Wall don’t have this problem. Could you please tell us what’s the version of the firmware of these EAP models?

Omada-Software is running on CentOS with Version 3.2.1

 

The Firmware of the

225-wall: 1.2.0 Build 20190222 Rel. 34350

115-wall: 1.4.0 Build 20190216 Rel. 60523

 

But the other AP's don't belong to the Problem becaus:

The behaviour of the EAP245 is the same on an seperated VLAN with seperate, fresh installed Omada-Controller.

 

Another test i just did is resetting the EAP245 again and not adopting it with any Omada.

In stand-alone-mode the EAP245 just shows up settings for 2.4GHZ.

Changing those settings is also not possible because the frontend complaines that the Tx Power(EIRP) should be "dBm (10-0)". Neighter the default value of 19 nor any other Value is accepted.

The default Network "TP-Link_2.4GHz_5002A8" is not bradcasted.

Trying to reupload the actual firmware is not possible, the frontend replies "The version is the same as the running firmware."

From the screenshot, it seems that there is something wrong with the firmware. We recommend you to download the latest firmware (20180323) and upgrade it again.

@forrest 

Can you please describe me how to do that?

As written in my last post: "Trying to reupload the actual firmware is not possible, the frontend replies "The version is the same as the running firmware.""

At a remote-session (Teamviewer) it became clear that the Firmware was broken.

The EAP refuse to flash the same (actual) firmware.

Therefore it is mandatory to downgrade first (flash any older firmware) and upgrade again to the actual version to renew the firmware.
