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)
