established, the WAN link LED will light up red. The reason for this is usually

Numerous other factors involving the Internet itself can also influence the
transfer rate.

Increasing the TCP/IP window size under Windows

If the actual transfer rate of a DSL connection is significantly below the fast-
est rate listed by the provider, there are only a few possible causes (apart
