If you are seeing slow Internet speeds under Linux (2.6.17 or newer) or Windows Vista make sure your router supports RFC 1323. If it does not then this is likely your problem. To fix it, upgrade or replace your router. RFC 1323 is a performance enhancement for TCP/IP networking which LInux and Vista support. Unfortunately, it seriously hurts performance if the network hardware doesn´t support it properly (or at all).
