> Is it actually possible to replace the WiFi card in a laptop? That depends. Unless it's a sealed case, you should be able to open it up and replace the wifi card with one that fits. However, a worryingly large number of manufacturers implement hardware locks which prevent user-installed wifi cards from working with the rest of the computer, denying you control over your own hardware. I don't think that is the case with Toshiba, but Lenovo, IBM, Dell, HP, and few others do engage in this nasty practice.
Your safer just using a USB wireless adapter from Tehnoetic or Thinkpenguin.
