Hello, I'm having some trouble deciding wich tecnology I should buy for getting Wi-fi on my bedroom. I already count with a TL-PA4010 KIT, and I wanted to know if it would be better to get a TL-WPA4220 or a tp-link router for the same price and get it connected to my TL-PA4010 KIT. I'm not sure about the adventages and disadvantages, and it would be great if someone could give me some advice! Thanks!
