Increasing the TCP/IP window size under Windows
If the actual transmission speed over a DSL connection is significantly lower
than the maximum specified by the DSL provider, there are very few potential
error sources with your own equipment.
A typical problem arises when a Windows PC simultaneously sends and
receives large quantities of data over an asynchronous connection. This situ-
ation can severly impact download speeds. The cause of this is the RCP/IP

value is too small for asynchronous connections.
Instructions for increasing the windows size are available in the Knowledge-
Base in the Support area of the LANCOM Systems Web site (www.lancom.eu).
