They will only troubleshoot to a PC connected directly, but most providers now include a router with your deal. You are paying for the 1.5Mb (or whatever the case may be) throughput to your house and they don't mind much what you do with it from there aside from having a web server or something similar. Wired routers are pretty secure and wireless ones can be reasonably secure if you get a newer one.

I am sure someone else could 'splain it bester.
