Make sure that the primary network card (non-wireless) is enabled by
right-clicking on "my network places" and selecting properties, then check
to make sure the interface has TCP/IP installed on it still by checking its
properties in the same manner as well. If all checks out there, go to your
start menu and then "run", type in "cmd" and hit enter. At the prompt of the
window that pops up, type in "ipconfig /all" and hit enter. Paste the
results in here, and I should be able to understand the problem a bit
better.
