@Sunshine sorry but did you read my post?

I dont know which is the correct page for my device due to the inconsistency on this Website. The search doesnt yield a result, modifying the url directly works but does not mention a firmware update. The same model in other langusges does so its absolutely confusing.

And to your second question i wrote 'out of curiosity'. Also, if a newer firmware does exist, its for a reason. Why would i not want bugfixes, increased stability or whatever they may bring?

Usually the new firmware for a product is to add new features or fix bugs.

Yes, thats .. what i was saying?

So if it is now working normally and it has no new firmware version released, you do not need to upgrade the firmware.

I know that i don't have to update the firmware if there are no new versions but based on the inconsistent results i am getting from this website, i don't know if there are any for my device. That's what i want to figure out.

And about the issue you mentioned, that it cannot be searched on the DE website and cannot find the firmware, I will feed this back to the local website admin, and let them check it. 

The issue is not that i can not find the firmware but the entire TL-PA717 KIT device is missing from the search in DE.
