my ATT cable in the seattle washington area is crapping out, i cant even play games online anymore. i just want to know if i have everything optimized or if there is anymore i can do to it.
TCP options string = 020405b40103030401010402
MTU = 1500
MTU is fully optimized for broadband.
MSS = 1460
Maximum useful data in each packet = 1460, which equals MSS.
Default Receive Window (RWIN) = 642400
RWIN Scaling (RFC1323) = 4 bits
Unscaled Receive Window = 40150
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: 25696 kbps (3212 KBytes/s) @ 200ms
Your RcvWindow limits you to: 10278.4 kbps (1284.8 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 51 hops
TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349)= 00000000
i am new to tweaking broadband and i am using the tcp optimizer to help and i was wondering what the TTL setting should be, it is at 64 now.
Is my cable optimized??

in the tcp optimizer there is the
Tcp 1323 Options
and the only thing you can change is
window scaling
and timestamps.
how do i change the Tcp1323Opts to 0? do i have to go into the registry??
im new to this stuff, so i need to have stuff explained to me as if i was a little kid.
just not in that tone hehehee.
also here are all my settings
usedomainnamedevolution 1
enablecmpredirect 1
deadfwdetectdefault 1
dontadddefaultgatewaydefault 0
enablesecurityfeature 0
sackops 1
tcp13230pts 1 (i dont know where to alter this)
defaultTTL 64
enablepmtubhdetect 0
enable pmtudiscovery 1
globalmaxtcpwindows 64240
tcpmaxdupacks 2
maxmtu 1500
mtu discovery yes
black hole detect no
selective acks yes
max duplicate acks 2

Do the following in the TCPOptimizer:
Settings tab:
select - cable modem
check - custom settings
network adapter selection - your NIC
check modify all adapters
maxmtu - 1500
TTL - 64
TCP Receive Window - 64240
MTU Discovery - yes
Black Hole Detect - no
Selective Acks - yes
Max Dup ACKs - 2
TCP 1323 Options - uncheck both boxes
Other Settings tab:
Max Connections per Server - 10
Max Connections per 1.0 Server - 20
Lan Browsing Speedup - optimized
Then select "Apply Changes" and reboot to take effect.
