The s8 is shown as connected to one of the decos just now (it's been like that before then reverts to the unavailable messages above)  but a quick check of the network shows the iPad is currently in the same situation. It works fine and shows in the main device list as connected but if I check each individual deco's connected devices it's not shown against any of them. I've also seen the same on a galaxy s9 and the iPad. 

All 3 decos are showing 1.3.1 and there doesn't seem to be any problem with connectivity. 

Edit 

Just to add a look on the management pages at 192.168.68.1 shows the ipad below having a wired connection which is clearly wrong

The 3 devices I see problems with are a Galaxy S8 and S9. Both european models with Exynos processors

The third is an Ipad UK model 

Yes as per origonal post the devices work just fine its just odd there are shown as wired when they are not. My S8 has shown as connected to all three deco's in the house at some point but often it gives the error above in the Deco app.  At no point have I had any pop up message though 

Ok so as of 5 mins ago my S8 was showing in the deco appwith the above error so pinging from a wired windows 10 machine

I am seeing the same error on some devices on my new M5 install.

Doesn't seem to affect connectivity of the devices in any way, and seems to be when the device has roamed from one mesh point to another.

Latest firmware.

Simon.

I have the same issue,and I do have a problems with my slave decos,they often offline, and the weirdest part- the app shows there is no connected client to the main deco unit.

I have a set of 3 pack,

firmware 1.3.1 on each,

the main deco working in router mode,

this is my second set of m5 , the first one has not issues like that,

@Kevin_Z 

We are also seeing this message " Unavailable for current firmware" . All 3 M5 Decos's have the same firmware . This issue seems to occur when a device first connects to the network then roams to another AP. It is not limited to Android devices,Apple devices are also impacted. But my iPad roams happily and reports where it is connected.However, an iPhone is currently showing as  " Unavailable for current firmware", yet this device is normally shown on the correct AP. Network connectivity is not impacted when this device location is not shown.
