I need to be able to connect a number of wifi devices to a laptop without proper infrastructure; specifically this is my use case...
I have a number of devices that utilize wifi, I have a laptop with my application running. I need to have connectivity between the laptop and the wifi devices. The environment that this runs in means there will not be proper wifi infrastructure.
So I need a method that will connect to my laptop via USB, CardBus or express card (i.e get power from the laptop) that will provide an access point for my devices to connect to. My devices do not support being connected to an ad hoc wifi network, so it needs to be a 'proper' access point. Also the laptop should then be able to be connected to the network through the medium that powers the device, USB for example.
I have found this device so far.
The problem is I can't figure out if my laptop would have to use its internal wifi to connect to the USB access point or if the connection can be through the USB.
I am not sure if such a product exists or not. Does such a product exist? I hope my question is clear!
