is this a good for cable?

i was just wondern if this was good for cable modem or not if not could ya give me some hints on what would be good to do.

TCP options string = 020405b4010303000101080a0000000000000000

MTU = 1500
MTU is fully optimized for broadband.

MSS = 1460
Maximum useful data in each packet = 1448, which is less than MSS because of Timestamps, or other TCP/IP options used.

Default Receive Window (RWIN) = 17520
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 17520
RWIN is a multiple of MSS
Other values for RWIN that might work well with your current MTU/MSS:
513920 (MSS x 44 * scale factor of 8)
256960 (MSS x 44 * scale factor of 4)
128480 (MSS x 44 * scale factor of 2)
64240 (MSS x 44)

bandwidth * delay product:
Your RcvWindow limits you to: 700.8 kbps (87.6 KBytes/s) @ 200ms
Your RcvWindow limits you to: 280.32 kbps (35.04 KBytes/s) @ 500ms
Consider increasing your RWIN value to optimize TCP/IP for broadband.

MTU Discovery (RFC1191) = ON

Time to live left = 23 hops
TTL value is ok.

Timestamps (RFC1323) = ON
Note: Timestamps add 12 bytes to the TCP header of each packet, reducing the space available for useful data.

Selective Acknowledgements (RFC2018) = OFF

IP type of service field (RFC1349)= 00000000

What OS please,, system specs, do you have speed patch installed, if so whose

and how do you connect

Lobo do you know how to re program a cable modem so you could change the take off the cap? Thanks

No I believe cable company is only one could do that, If I knew how I'd be rich $$$$$

I mean raise the cap. It seems like a cool idea to me.

No I don't know how to do that but maybe buggyman does at here

I didn't find anything at all that has to do with re-programming my cable modem.

Yes go into tweaking forum and ask him how

Lobo buggy man says he doesn't know how to.

sounds like something Lobo would tell yah!
But hate to disappoint yah!
