Firing up the laptop should have no effect on the PC. They should be
able to access the Internet simultaneously and independently.

Here are some tests to help find the problem:

1. With the laptop turned off, right-click the PC's wired network
connection, click Status | Support | Details, and write down the
values that it shows for IP Address, Subnet Mask, Default Gateway, and
DNS Server.

2. With the laptop turned off, open a command prompt on the PC (Start
| Run | cmd) and type these commands. Each one should receive four
replies:

ping <IP address>
ping <Default Gateway>
ping 216.239.39.99
ping www.google.com

3. Turn on the laptop, right-click its wireless network connection,
and write down the values that it shows for IP Address, Subnet Mask,
Default Gateway, and DNS Server. Compare the values to the PC values
in Step 1 above. The IP addresses should be different, and the other
values should be the same. The IP address should be different than
the Default Gateway.

4. Repeat Step 1 on the PC. The values should be the same as they
were before.

5. Repeat Step 2 on the PC. The results should be the same as they
were before.
