Cox Preferred....Help make it faster :)

[kvnband]

I'm on the Cox preferred plan.  I was getting about 520-530 KB/sec down but then an installer came out today to add cable and I'm down to 503 KB/sec down....

1.  Running Win XP

2.  Cox Cable 4mbps download, 512Kbps upload

3.  Cablenut installed (but don't know what ccs file to use)...

TCP options string = 020405b40103030201010402

MTU = 1500

MTU is fully optimized for broadband.

MSS = 1460

Maximum useful data in each packet = 1460, which equals MSS.

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:

513920 (MSS x 44 * scale factor of

256960 (MSS x 44 * scale factor of 4)

128480 (MSS x 44 * scale factor of 2)

64240 (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 = 55 hops

TTL value is ok.

Timestamps (RFC1323) = OFF

Selective Acknowledgements (RFC2018) = ON

IP type of service field (RFC1349) = 00000000 (0)

5.  Did it

6.  Yup

7.  Modem via Cat5 to router...Router via cat5 to 3 PCs (Don't know how to set modem duplex, and the stupid ass microsoft router (yard sale buy) doesn't have duplex settings anywhere).  I do have the latest modem and router firmware, however

8-14.  Done

15.  Downloaded cablenut, but can't find a suitable file in version 9....

Thanks for any help anyone can give...

welcome to the forum kvnband,

do this clear your cache and then run this test. http://www.testmy.net/tools/test/d_load.php?step1_timed=&step1_size=&step1_validation=&testall=&s=5983&st=st&ni=ni&ta=&top=&tt=1&nobar=

try a little bigger test, clear your cache before you test http://www.testmy.net/tools/test/d_load.php?step1_timed=&step1_size=&step1_validation=&testall=&s=12160&st=st&ni=ni&ta=&top=&tt=1&nobar=

its still good, your above your advertised. your internet is fine, and your getting really good speeds from it. 

[kvnband]

Yup yup...I'm happy......

How come, though, when I run the smart test, on the 5983 test (or whatever that number is) it finally shows me a speed of 502?

its just something that happens some times, it happens to me, when i do the smart test i get about a 250kbps - 500kbps lower result unless i clear my cache that happens to me because i keep such a small cache.(1mb)
