Hi,
I'm using a WPA281 kit (300 Mbs AV200 Wireless N): it's made of 2 different devices:
- the first one (smaller, no exact model is present on the device) is connected to the the router
- the second one (bigger, model is WPA281) is used to connect my PC in another room.


Now I would need to connect 2 more PCs in 2 different rooms but I don't know which model I should buy: I've seen that many devices are sold as "starter kit" and I'm not sure if I can use them just to add 2 more PC or if they can be used only as the one I have (one connected to the router and the other to the PC).


Could someone give me some models that are compatible with my existing kit?
For example, could the TL-PA411 be a right option?


Last question: why the 2 devices of my kit are different while in other ones (like the PA411 above) the 2 devices are exactly the same?


Thanks,
Corrado
