What speed did you pay to get?

8mb

I suspect your OS is Vista. TCP Optimizer cannot tweak Vista.

But your MTU is not within normal value: 1500 for cable internet or 1492 for ADSL.

Try the following with TCP Optimizer and see if it can help to correct your MTU value:

General Settings tab:
Custom settings - check
Modify All Network Adapters - check
network adapter selection - your NIC
MTU 1500
TTL - 64
TCP Receive Window - leave blank
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

The MTU is correct, but it seems your Vista's auto-tuning is turned off.

Ensure your Vista auto-tuning is enabled.

Go to Start --> Run and paste this " netsh int tcp set global autotuninglevel=normal " and hit Enter.

Yes the settings are correct. MTU is at 1500 and auto-tuning is turned on.
