I recently created a home network between my desktop and laptop. My cable modem is connected to my desktop through a NIC, and the connection is shared with my laptop via CAT5 and the intigraged network card on the desktop's motherboard. Both PCs are XP.
When the internet is being used on the laptop, my mouse (and my programs to a certain extent) lag. Why? Should I try another NIC in the desktop and not use the integrated one?
