Someone help me tweak my connection please

TCP options string = 020405b40103030101010402

MTU = 1500
MTU is fully optimized for broadband.

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

Default Receive Window (RWIN) = 93440
RWIN Scaling (RFC1323) = 1 bits
Unscaled Receive Window = 46720
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: 3737.6 kbps (467.2 KBytes/s) @ 200ms
Your RcvWindow limits you to: 1495.04 kbps (186.88 KBytes/s) @ 500ms

MTU Discovery (RFC1191) = ON

Time to live left = 48 hops
TTL value is ok.

Timestamps (RFC1323) = OFF

Selective Acknowledgements (RFC2018) = ON

IP type of service field (RFC1349)= 00000000

I have Cable (Rogers@home), 1500/192
I tested my speed and its at 1132/184
I have Windows xp
And another thing can u help me increase my upload speed i read in Dr.Tweaks Tips that i could incease the defaultsend speed or something like that

I really doesn't look that bad. It needs a minor fix here and there but you're in the game. Slow night tonight. Someone smart will be along in the AM to give you a hand.

Your upload cap is 192 and you are at 184 that is very good, you aren't going to get anymore out of it.

I C

My download is only 1264 out of 1500 there still a lot more left :P

You are at about 85% of your caps which is very good, there are probably causes beyond your control that you are not going to get anymore.
