Slow network access

I have a notebook which demonstrates slow network access
on my home network but not on other networks such as my
office. At home I have a T1. Through the nic on the
notebook I am obtaining at best in the 200k range for
downloads sometimes lower. A PC that also connect
through a nic, as opposed to wireless, downloads at 1.4
meg. Both are wired through a switch into a router. I
plugged the notebook into the same wire that the PC uses
and got the lower speed. Both have static ip addresses.
Otherwise the settings are the same. I took the notebook
to the office, plugged it into the office network after
changing to a different static ip and obtained 1.3 meg.
I'm running Zone Alarm on it but taking that down doesn't
help. I've tried tweaking with various programs and that
doesn't help. Anyone have any idea? Thanks!
 
This may be due to high latency that you have at home over the T1 line.

There are several utilities out there that can optimize your TCP Sliding
Window for a specific situation, however, if you are comfortable with the
registry, you can try to increase your TCP Sliding Window size yourself:

See 'TcpWindowSize' in the following article.
http://support.microsoft.com/defaul...port/kb/articles/q314/0/53.asp&NoWebContent=1

The default value is 8760 (2238 hex). You add the TcpWindowSize key as
specified in the article, to the
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\TcpIp\Parameters
location and set it to a higher value (such as 0xffff).
