@Solla-topee Thanks

I'm considering to return the device for a refund for the following reasons:

• Lazy default configuration - wifi country code is hard-coded to DE whereas my TL-WPA8630P was (correctly) configured to GB at the time of manufacturer. TP-Link are doing the same on some of their router range as well which is poor. For most users this won't cause a problem but for my scenarios it does. Not having CLI access to correct this fault is also poor. I know it's a consumer product but so are their routers!
• tp-PLC (Android) V1.3.5 will not detect my TL-WPA8630P as a Device - only the TL-PA8010P 2.0 & the new TL-WPA8631P . If I select one of these and look at Data Rate the other device IS showing. Sometimes I can get it to display if I repeatedly refresh the screen. If I then change the name this resets on next use. This app has not been updated since 27th September 2020 although the product was released earlier so i would have expected it to be recognized. tp-PLC for Windows works fine. Is there a new release of the Android app in the pipeline?

Performance has stabilized but I had to factory reset all three devices and start again from scratch. I shouldn't have to do this

Thanks again
