Not that I know of.

Try testing at this link and when test is completed, click the 'More Details' button and post the pop-up report:

Your sending RWIN is low at 5840. Usual value is 16304.

Your receive RWIN is too high. It should be 256960 to suit a latency of 250ms.

Run the WinSockFix to see if your sending RWIN can be increased:

Oops. Now your Receive RWIN is too low at 17520.

Use the following with TCP Optimizer:

General Settings tab:
Custom settings - check
Modify All Network Adapters - check
network adapter selection - your NIC
MTU 1500
TTL - 64
TCP Receive Window - 256960
MTU Discovery - Yes
Black Hole Detect - No
Selective Acks - Yes
Max Duplicate ACKs - 2
TCP 1323 Options:
Windows Scaling - checked
Timestamps - uncheck

Advanced Settings tab:
Max Connections per Server - 10
Max Connections per 1.0 Server - 20
LocalPriority - 1
Host Priority - 1
DNSPriority - 1
NetbtPriority - 1
Lan Browsing speedup - optimized
QoS: NonBestEffortLimit - 0
ToS: DisableUserTOSSetting - 0
ToS: DefaultTOSValue - 80
MaxNegativeCacheTtl - 0
NetFailureCacheTime - 0
NegativeSOACache Time - 0
LAN Request Buffer Size - 32768
Then select "Apply Changes" and reboot to take effect

Your TCP Analyzer shows settings at correct values.

How is your speed in the night?

If you still get a slowdown, do a tracert to http://www.yahoo.com during the slowdown and compare it with another tracert during normal speed to spot for differences in ping times and thus isolate the cause.
