I have a dsl connection which is pppoee based i.e we have to put username and password in order to connect to the internet.

Acutully my dsl provider give me a USB Adapter here is the link of usb adapter he has given me http://www.tp-link.com/us/products/details/?categoryid=243&model=TL-WN7200ND[^].

he removed the antena from the back side and connect this usb adapter to the wire which is connected to some device on my roof( antena) in order to improve wireless signals that are coming from their main router.

now i connect to the dsl just through usb wire to this wireles adapter whose antena side is connected to the roof antena with the help a wire.(it limits me to use dsl only in one room) i want to connect through my dsl wirelesly in my house.

I want to ask a question can i connect this usb adapter to any wireless switch to enable my dsl to wirelessly available at my house???
