My computer is downloading things at 45kbps at maximum. I also have another computer but it's downloading at speeds of 290 sometimes more than 300 kbps. And I don't have a router either. I'm just directly connecting each of the computers to the cable modem one at a time. Can anyone please help me fix this? It gets real annoying when I try to upload stuff to my website when I can only upload at this speed. And it takes forever to download really large applications. Well thanks in advance for the help. Oh and here are the five questions answered.

1. I have a Cable Connection.
2. I'm subsribed to Charter Pipeline and the advertised speed is 384kbps.
3.

TCP options string = 020405ac0103030001010402
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 MTU to 1500 for maximum throughput.
Default Receive Window (RWIN) = 10164
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 10164

RWIN is a multiple of MSS
Other values for RWIN that might work well with your current MTU/MSS:
511104 (MSS x 44 * scale factor of 8)
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 RcvWindow limits you to: 406.56 kbps (50.82 KBytes/s) @ 200ms
Your RcvWindow limits you to: 162.624 kbps (20.328 KBytes/s) @ 500ms
Consider increasing your RWIN value to optimize TCP/IP for broadband.
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

4. I'm using Windows XP.

Try thease in the sg optmizer below me to download and install when done saving changes and rebooting take another analyzer i have to see if mtu got ajjusted.

select - cable
check - custom settings
network adapter selection -
check modify all adapters
maxmtu -1500
TTL - 64
TCP Receive Window leave blank
MTU Discovery - yes
Black Hole Detect - no
Selective Acks - yes
Max Dup ACKs - 2
TCP 1323 windows scailing is checked
Other Settings tab:
Max Connections per Server - 10
Max Connections per 1.0 Server - 20
Lan Browsing Speedup - optimized
Then select "Apply Changes" and reboot to take effect.
