Get help and discuss anything related to tweaking your internet connection, as well as the different tools and registry patches on the site. TCP Optimizer settings and Analyzer results should be posted here.

my MTU and MSS is way off i need help!

Post by Faction »

i have a dell inspiron 1300 w/ dell internal wireless. xp home w/ sp2. my analyzer results are normal whenever i'm on the wired connection but when im wireless my settings are wayyyy off.

Results
MTU = 1400
MTU is not fully optimized for broadband. Consider increasing your MTU to 1500 for better throughput. If you are using a router, it could be limiting your MTU regardless of Registry settings.
MSS = 1360
MSS is not optimized for broadband. Consider increasing your MTU value.
Default TCP Receive Window (RWIN) = 37752
RWIN Scaling (RFC1323) = 0 bits
Unscaled TCP Receive Window = 37752

For optimum performance, consider changing RWIN to a multiple of MSS.
Other RWIN values that might work well with your current MTU/MSS:
522240 (MSS x 48 * scale factor of 8)
261120 (MSS x 48 * scale factor of 4)
130560 (MSS x 48 * scale factor of 2)
65280 (MSS x 48)
bandwidth * delay product (Note this is not a speed test):

Your TCP Window limits you to: 1510.08 kbps (188.76 KBytes/s) @ 200ms
Your TCP Window limits you to: 604.032 kbps (75.504 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 (0)
