Mnosteele helped me with my DSL at my alt location & worked well
So I was hoping for the same with my Wireless connection at my main base
Advertised as 512 up
128 down am I getting all I should?

TCP options string = 020405b40103030201010402
MTU = 1500
MTU is fully optimized for broadband.
MSS = 1460
Maximum useful data in each packet = 1460, which equals MSS.
Default TCP Receive Window (RWIN) = 1460
RWIN Scaling (RFC1323) = 2 bits (scale factor of 4)
Unscaled TCP Receive Window = 365

RWIN seems to be set to a very small number. If you're on a broadband connection, consider using a larger value.
RWIN is a multiple of MSS
Other RWIN values 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 (Note this is not a speed test):

Your TCP Window limits you to: 58.4 kbps (7.3 KBytes/s) @ 200ms
Your TCP Window limits you to: 23.36 kbps (2.92 KBytes/s) @ 500ms
Consider increasing your RWIN value to optimize TCP/IP for broadband.
MTU Discovery (RFC1191) = ON

Time to live left = 52 hops
TTL value is ok.
Timestamps (RFC1323) = OFF

Selective Acknowledgements (RFC2018) = ON

IP type of service field (RFC1349) = 00000000 (0)

Use the same settings as I gave you before bluzeboy.

I thought the differance in promised bandwith there would be differances.

This is on the same connection correct? This pc is just wireless right? I might have misunderstood you.

this a different computer & different connection my alt computer was dial up before & i got DSL it.

OK, but those settings should work for this connection as well.
