TCP options string = 020405b40103030101010402

MTU = 1500
MTU is fully optimized for broadband.

MSS = 1460
Maximum useful data in each packet = 1460, which is equal to MSS.

Default Receive Window (RWIN) = 128480
RWIN Scaling (RFC1323) = 1 bits
Unscaled Receive Window = 64240
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)
64240 (MSS x 44)

bandwidth * delay product:
Your RcvWindow limits you to: 5139.2 kbps (642.4 KBytes/s) @ 200ms
Your RcvWindow limits you to: 2055.68 kbps (256.96 KBytes/s) @ 500ms

MTU Discovery (RFC1191) = ON

Time to live left = 30 hops
TTL value is ok.

Timestamps (RFC1323) = OFF

Selective Acknowledgements (RFC2018) = ON

IP type of service field (RFC1349)= 00000000

Norm's got a point there. I passed it by because I thought it was a adolescent (they come in all ages) with limited verbal skills. Hard to communicate with them espeically when they’re cranky (like your subject line indicates).

Welcome to SG all the same!
