MTU may be limited by this USB modem.
Perhaps MTU can be increased using a router instead, and the router will also provide a hardware firewall through its NAT function. See this:

Use the recommended values in blue above. Setting the value too high will cause slowdown if your line suffers packet retransmissions.

Napsters, you may want to start a new thread since this is a different computer.
As trogers would say, " Optimizer does not work with Vista", however there may be some things he or rollingstone could suggest.
see Philip's article on Windows Vista Tweaks:
http://www.speedguide.net/read_articles.php?id=2574
Run Analyzer and speed test using the laptop and post the results.
Open command prompt and run netsh int tcp show global and copy/post results.
This is what I get, yours should be similar.
C:\Users\SayrePC>netsh int tcp show global
Querying active state...
TCP Global Parameters
----------------------------------------------
Receive-Side Scaling State : enabled
Chimney Offload State : disabled
Receive Window Auto-Tuning Level : normal
Add-On Congestion Control Provider : ctcp ( may be none)
ECN Capability : disabled
RFC 1323 Timestamps : disabled

Have 1.5 Mbps DSL through Qwest (telephone company). Compaq SR2180NX, and 2Wire 2701HG-D modem/router. Usually get 1330 - 1360 kbps down.
First used Optimizer on my old computer that ran ME about 6 years ago when I finally got a 250 kbps DSL connection. Still have the old ME hooked up wireless to my modem and it averages about 1340 kbps.
