Hi,

The hyperlink assigned to the [Download] button on the "KIT" page is

https://static.tp-link.com/upload/firmware/2023/202308/20230829/TL-WPA8631P(EU)_V4_230817.zip

and the hyperlink assigned to the [Download] button on the "non-KIT" page is 

https://static.tp-link.com/upload/firmware/2023/202308/20230829/TL-WPA8631P(EU)_V4_230817.zip

So, you are downloading exactly the same file in both cases.

  @woozle Ho Woozle.

Yes, I am aware that it is the same file. the confusion is that it says for "TL-WPA8631P KIT(EU)" even on the download page for the "non KIT" version.

So, does it only apply to units that actually mention "KIT" on their name plate sticker on the back, or to any TL-WPA8631P V4 for Europe (both KIT and non KIT)?

  @woozle Spot on and thanks for your help. Encouraging enough to just go for it.

Perhaps TP-Link should simply not provide a separate page for the "KIT" and remove the "KIT" from the firmware name as it is not an actual "version" but simply a package of two components which each have their own support page.

And: yes, I well understand that the wired "base unit" TL-PA8010P requires different firmware (it has its own page for that).

Best,

Thomas
