Connection Dropping!!

[Vish32608]

If anyone can please help me I would be very appreciative.

I have a P4 2.4 with cable internet service that is fed via satellite from my apt complex. I continue to have trouble with my connection dropping. I then have to shut down the computer, disconnect the modem power and reboot.

Also, my connection speed is horrible, about 250-300kb.sec downstream only. I have tried many tweaks here, but am unable to increase my MTU.

Please help.

TCP options string = 020405640103030201010402
MTU = 1420
MTU is not fully optimized for broadband. Consider increasing your MTU to 1500 for better throughput.
MSS = 1380
MSS is not fully optimized for broadband (although it might work well for slower connections). Consider increasing your MTU value.

Default Receive Window (RWIN) = 256960
RWIN Scaling (RFC1323) = 2 bits (scale factor of 4)
Unscaled Receive Window = 64240

For optimum performance, consider changing RWIN to a multiple of MSS.
Other values for RWIN that might work well with your current MTU/MSS:
507840 (MSS x 46 * scale factor of 8)
253920 (MSS x 46 * scale factor of 4)
126960 (MSS x 46 * scale factor of 2)
63480 (MSS x 46)
bandwidth * delay product:

Your RcvWindow limits you to: 10278.4 kbps (1284.8 KBytes/s) @ 200ms
Your RcvWindow limits you to: 4111.36 kbps (513.92 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 54 hops

TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349) = 00000000

What windows version you got also please stick to one thread thank you.

Also are you using intrenet connection sharring and or virtual private network software.

I am sorry for using more than 1 thread.

I am using Windows XP and am not using VPN or any other software to connect to the internet.

Thank you for your help Mccoffee.

Ok just for now try downloading the sgoptimizer select cable on top and optimal on bottom and reboot and take another analyzer like you did above and see if it changed.

No sweat about different threads it's just eaiser on everyone

[Vish32608]

No change.
