ArcticWolf ~ run TCP/IP analyzer to check your MTU, then you can try Cablenut Settings Calculator to make YOUR own .css file. . .run a tracert from the command prompt,  to determine your latency.

. . .under 'Cablenut Setting Files', you may want to copy 'Printable Settings' and 'save as' in Notepad.  Then insert the settings manually into Cablenut Adjuster ~ then 'SAVE as' ~ to create YOUR .css file ~ then 'Save to Registry' in Adjuster.

Hi Artic Wolf,

We can try to use the TCP Optimizer to set the MTU to its highest value if this value is not a limitation imposed by your modem/router. In the latter case, adjustment has to be made by tweaking the driver of the hardware.

Download the TCP Optimizer at www.speedguide.net and do the following:

General Settings tab:

Custom settings - check

Modify All Network Adapters - check

network adapter selection - your NIC

MTU - 1500

TTL - 64

TCP Receive Window - blank

MTU Discovery - Yes

Black Hole Detect - No

Selective Acks - Yes

Max Duplicate ACKs - 2

TCP 1323 Options:

Windows Scaling - uncheck

Timestamps - uncheck

Advanced Settings tab:

Max Connections per Server - 10

Max Connections per 1.0 Server - 20

LocalPriority - 5

Host Priority - 6

DNSPriority - 7

NetbtPriority - 8

Lan Browsing speedup - optimized

QoS: NonBestEffortLimit - 0

ToS: DisableUserTOSSetting - 0

ToS: DefaultTOSValue - 240

MaxNegativeCacheTtl - 0

NetFailureCacheTime - 0

NegativeSOACache Time - 0

LAN Request Buffer Size - 32768

Then select "Apply Changes" and reboot to take effect

You can use the feature in TCP Optimizer to find the value of your largest MTU.

Open TCP Optimizer, set MTU to 1500, click 'Largest MTU', then enter any website address and click 'Start'. Your comp will send out pings and establish your system's largest MTU value.

If your largest MTU value is more than 1452 we can make a ccs file for you following the value.

If after trying both and MTU is still set at 1452, here is a ccs file for this setting.

After loading this ccs file and speed testing, you can make modifications to the following 2 fields and see if it works better:

DefaultReceiveWindows - 62128

Tcp13230pts - 0

RWIN setting of 124256 is suitable for latency range of 150-300 ms.

RWIN setting of 62128 is suitable for latency less than 150 ms.
