As far as i know, two TL-WA701N can do what the instruction shows. However, i also know that one can be AP, another one can be repeater or client to establish the wireless connection between two units. That depends on your purpose on how to use them. If one is TL-WA701ND, the other is another model but also access point, this would be no problem but not sure because if some products are too old, then there could be some problem. I am sure that the model like TL-WA701ND with tl-wa801nd, tl-wa901nd, there can be connected wirelessly to each other.
