I'm not completely sure which specific version of the TL-WN725N adapter you have. The information available does not explicitly state whether it is the V1 or V2 version. To obtain this information, you can check the packaging or contact the manufacturer directly for more details.

The TP-Link TL-WN725N Wireless N Nano USB 2.0 Adapter is not strictly plug and play, as it may require the installation of drivers to function properly. While it is relatively easy to set up, users typically need to install the provided drivers or download them from the manufacturer's website to ensure full functionality.

Sorry, I don't know, it doesn't say. You would have to ask the PM.

Unfortunately I cannot answer your question. This adapter works great for using a wifi router to go online.

Mine (bought August 2014) is a Realtek RTL8188EU (USB Id 0bda:8179).

What do you mean by normal USB? USB is a standard and backwards compatible. This means that you can also use it with a USB 3.0, but just pay attention to the plug compatibility.

Ja, es läuft auch unter Windows 10.

Yes, this should work under Raspbian. However, I recommend the following USB dongle for one franc more: TP-LINK TL-WN823N (USB 2.0, 300Mbit/s)
