Question, got a wireless router, laptop, and desktop pc. Desktop is connected to internet via ethernet cable, no wireless card installed. Laptop is a macbook and works fine on wireless to get to internet. However they cannot see each other on my network. As in the laptop cannot ping the pc successfully, but the desktop can ping the laptop. So it's like the laptop just can't see the desktop. Anyway to fix this, or do I need to get a wireless card for the desktop? Btw, wouldn't be too concerned if my network went all wireless as I'm running WPA security, with 64 character length HEX password, and can enable MAC address filtering, as well as running software fiewall on the desktop.
