I have Dial-up. I do not know how they will be connected as I don't have my laptop yet but just wanted to know what it'd be like...That will depend on how you are connecting both. Are you on dsl or cable? If you are connecting through a router both being on one line will have a tendency to pull down the bandwidth slightly. If one is being used for downloading a large file that will be more noticable. But if your connections are discreet each on a separate port you shouldn't see any large drop.
