Hi Siyu Qio,
I'm not sure to understand your question, but this is what I did
- went to the shop to buy this USB stick
- plugged it in a USB slot of my PC
And now I'm trying to understand if I can switch/enable/disable these 2
bands, and more importantly, do I really need to?
Right now, my feeling is that "it just works out of the box", I
shouldn't try to do this kind of things. I just try to understand this
dual-band thing.
Chris
