Missing radio interfaces on EAP615-Wall
Missing radio interfaces on EAP615-Wall
2022-07-24 21:20:40
Model: EAP615-Wall  
Hardware Version: V1
Firmware Version: 1.1.0

Looking through my controller UI recently, I noticed that no client devices were connecting to one of my EAPs (EAP615-Wall). When I reviewed the its configuration, I noticed that neither radio had a channel configured. So I logged into the device via SSH and ran ifconfig, but it only showed eth0, lo, and br0 interfaces. The ra0 and rax0 interfaces were missing!? Restarting, resetting, running standalone, downgrading, upgrading, switching POE ports/switches... all did nothing. It seems like a hardware issue, but why would this happen all of a sudden? The device was fairly cool to the touch (unlike my other 615, which was warm), so I'm at a loss as to what happened. Has anyone experienced this before and, if so, what did you do?

  @prooney It looks like a hardware issue. After resettings there should be a default SSID called "TP-Link 2.4Ghz_XXXX", if you cannot see this default SSID, you can contact tplink and ask for warranty

  @Somnus, thanks for replying. Yes, I've contacted support to investigate the issue, but I agree it's likely a hardware problem. For completeness' sake, here's what I'm seeing in the controller for that EAP:

 

But for a functioning EAP, here's what I see:

 

 

And from SSH, I only see eth0, lo, and br0:

/bin $ ifconfig

Hope this helps someone else identify this issue.

  @prooney are you solve the issue?
why you have big amount of error and dropped packets?

+20y experience in Linux/UNIX, +12y VMware, +10y as network admin, +8y as AIX admin (professional) I really know what is going on at background, please don't try to cheat me TP-Link :)
