(that above is actually a wap router, see link above, look at the pix of the back) dsl modem to wap/router gives you both wired and wireless as for usb, you want them for the game things (they make usb wifi adaptors for game machines tivos etc), or do you want usb 'dongles' for puters with usb but no wifi? you can cable from the router part of the wap router to one of the powerline transceivers (Plug the other in where you want a wired connection) powerline essentially replaces running a dedicated cable..... laptops usually use mini pci cards for wireless, desktop usually use full sized pci cards for wireless, both (if it has a usb port) can use a usb dongle for wireless wonder from the subject if you knew that they can all work together, and be AND's instead of VS.... personally, i use all three, and they play well together... |
