[nhoj333]

i just upgraded from bellsouth dsl lite , 256 kbps , to extreme 6.0 mbps

Post your TCP Analyzer report.

Two reasons for your low speed:

Your MTU should be 1492 with Bellsouth DSL and your TCP Window (RWIN) is set too low.

Do the following with TCP Optimizer:

General Settings tab:
Custom settings - check
Modify All Network Adapters - check
network adapter selection - your NIC
MTU 1492
TTL - 64
TCP Receive Window - 127776
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

After reboot, post a new TCP Analyzer report to see if your MTU and RWIN have been correctly reset.

download DRTCP and use it to put your RWIN.
