I 'am currently with @home (3000kbps/400kbps)
I have the Ericsson PipeRider modem. Please tell me what i should do to increase performance. Thanks.

TCP options string = 020405b401010402

MTU = 1500
MTU is fully optimized for broadband.

MSS = 1460
Maximum useful data in each packet = 1460, which is equal to MSS.

Default Receive Window (RWIN) = 20000
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 20000
For optimum performance, consider changing RWIN to 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: 800 kbps (100 KBytes/s) @ 200ms
Your RcvWindow limits you to: 320 kbps (40 KBytes/s) @ 500ms
Consider increasing your RWIN value to optimize TCP/IP for broadband.

MTU Discovery (RFC1191) = ON

Time to live left = 116 hops
TTL value is ok.

Timestamps (RFC1323) = OFF

Selective Acknowledgements (RFC2018) = ON

IP type of service field (RFC1349)= 00000000

This a win98 OS if so go drop in a few patch's. On win98 you will need the Vtcp.386
the speed patch and the Speedguide WEB patch... go here http://www.speedguide.net/Cable_modems/cable_patches.shtml
