Hi Chunkerz,

to Cable Forum
In addition to what MGP has suggested above it would be useful to give some though to
how you are downloading.
Normal downloads from websites etc
shouldn't require any additional configuration, however if you are using any P2P programs (for bittorrents etc) you will probably need to look at forwarding/opening some of the ports on your router.
If you could confirm what/how you are trying to transfer that might make it easier to help diagnose the problem you are having.
