And I will ask about the laptop: are you sure that only one network adapter is enabled?
Either wired or wireless as needed but not both network adapters at the same time.
Run "ipconfig /all" (without quotes) via the Command Prompt.
Post the results.
Thanks for continuing to address my problem. There's only one Ethernet jack and a wireless adapter as far as I know. Here's the output from IPConfig/all (edited some results because I was concerned I might be revealing some information that should be not exposed publicly):
