Question
Hi Brian, my roommate and I each have a PC on one modem 2wire. Mine is XP wired and roommate is Vista wireless. When my roommate turns his PC on I loose my online conection on XP. I searched online, but found this same problem by other users and no solution. I doubt the problem is from malware and just wondered if you have heard of this occurring before and maybe have the solution. One user with this problem online said he even bought a new router with no luck.

Answer
Hi Mike

Sorry for the delay in getting to your question, as I've just returned from a week away.  The good news is that there is no malware associated with your connection problem.  My suggestion would be for you to try a different router.  Even though you stated someone else tried this solution, the router is not able to handle both connections, either due to a setting or a malfunction.  If you can, borrow someone else's router before purchasing a new one, just to be sure that this is the problem.  Also try replacing the ethernet wire going to your computer.  It may be faulty.  Let me know if any of these suggestions solved it for you.
