My desktop works fine as long as I don't use my laptop nearby. Just turning the laptop off doesn't help. Turning the internet off on the laptop didn't help, either.
If I unplug the aircard and take it to my art building, and use my laptop there, and just leave the laptop there, it doesn't interfere with my desktop.
My Kindle doesn't interfere, although my desktop tells me there's a conflict. I just close the box and everything seems to be fine. I tried to convince the program that it isn't a conflict since I want both to operate. It seems to think I don't have the authority to make that decision, but it still works.
