Can a laptop run two wifi adapters at the same time?
I'm just wondering if I should spend the money on another wifi adapter. My laptop has two usb ports, and I have the idea of using a second wifi adapter as a cheap signal strength meter for the first wifi adapter. I would use the adapters own software to show signal strength, and attempt to reduce it's ability to receive a full strength signal at point-blank range by wrapping it in aluminum foil.
Or will this just crash the laptop? Has anyone tried anything like this? What else could I do to run a signal strength meter for $20 while testing new wifi antenna's? Getting another laptop is out of my budget and I don't feel like spending $20 either if it wont work.
