I've been killing myself for weeks trying to get my connection optimized and i'm glad i found this site.  My speed as claimed by my ISP is 2.2Mbps but I'm not getting anything near it.  I'm using Win XP SP2, My ISP is PLDT MyDSL in the Philippines,  I''ve done a full virus scan with kasp[ersky 6 and a spywaare scan with ad-aware and I'm clean.  I've already installed Cablenut and am using the config for MSS 1452 and DSL PPPoE 2000 384.  My connection should be 2200 512 but there doesnt seem to be a config file for it and I'm guessing that might be the problem.  Any help or suggestions would be greatly appreciated.

Below are the analyzer,  speed test, ping and tracert results.


TCP options string = 020405ac0103030201010402
MTU = 1492
MTU is optimized for PPoE DSL broadband. If not, consider raising MTU to 1500 for optimal throughput.
MSS = 1452
MSS is optimized for PPPoE DSL broadband. If not, consider raising your MTU value.
Default TCP Receive Window (RWIN) = 256000
RWIN Scaling (RFC1323) = 2 bits (scale factor of 4)
Unscaled TCP Receive Window = 64000

For optimum performance, consider changing RWIN to a multiple of MSS.
Other RWIN values that might work well with your current MTU/MSS:
511104 (MSS x 44 * scale factor of Cool
255552 (MSS x 44 * scale factor of 4)
127776 (MSS x 44 * scale factor of 2)
 63888 (MSS x 44)
bandwidth * delay product (Note this is not a speed test):

Your TCP Window limits you to: 10240 Kbps (1280 KBytes/s) @ 200ms
Your TCP Window limits you to: 4096 Kbps (512 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 53 hops
TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349) = 00000000 (0)

estimate = 8.38 based on packet size = 11Kbits, RTT = 1321.92msec, and loss = 1.0E-6
The theoretical network limit is 8.38 Mbps
The NDT server has a 8192.0 KByte buffer which limits the throughput to 48.41 Mbps
Your PC/Workstation has a 250.0 KByte buffer which limits the throughput to 1.47 Mbps
The network based flow control limits the throughput to 1.48 Mbps

Client Data reports link is 'T1', Client Acks report link is 'T1'
Server Data reports link is '10 Gig', Server Acks report link is 'T1'

Just one more question.  This section has me wondering

Your PC/Workstation has a 250.0 KByte buffer which limits the throughput to 1.47 Mbps
The network based flow control limits the throughput to 1.48 Mbps

Client Data reports link is 'T1', Client Acks report link is 'T1'
Server Data reports link is '10 Gig', Server Acks report link is 'T1'

Does this mean my ISP is capping me at 1.48Mbps?

Welcome to the forum dobermaxx  wave Welcome!
I figured one of the DSL hotshots would have been in by now.

Anyway I would try the 1.5 DSL settings, or 3.0. Remember to back up if you don't like one you can always go back. And have you read this??

Thanks for the help dude.  I have read that thread and i'm clean and optimized as far as i can tell.   I'll try the 1.5 and 3 settings and see what happens

I have tweaked my settings with TCP Optimizer. You might like to give it a try.
