What modem? (please include a link to the mfr. support page
) What are the reported speeds using http://Speedtest.net?
What speed are you paying for? What happens when you reset the modem?
If you check the modem specs on the mfr. support page you'll see that modem also includes a built-in router, which means it should be perfectly fine to connect it directly to a PC. If you don't think you are getting the connection speed you are paying for then I recommend you contact your DSL provider, as those types of problems are most likely on their end. Let me know what you find, Scott.
