TCP options string = 020405b40402080a961152790000000001030309

MTU = 1500
MTU is fully optimized for broadband.

MSS = 1460
Maximum useful data in each packet = 1448, which is less than MSS because of Timestamps or other TCP/IP options used.

Default TCP Receive Window (RWIN) = 29696
RWIN Scaling (RFC1323) = 9 bits (scale factor: 2^9 = 512)
Unscaled TCP Receive Window = 58

In Unknown OS, unless TCP Auto-Tuning is disabled, only the current TCP window is displayed.
You seem to be using Unknown Browser. Some browsers may modify TCP window behavior.

RWIN is not multiple of MSS.
Other RWIN values that might work well with your current MTU/MSS:

• 64240
• 128480
• 256960
• 513920
• 1027840

Bandwidth * Delay Product (not a speed test):

• Your TCP Window limits you to ~1188 kbps @ 200ms latency
• Your TCP Window limits you to ~475 kbps @ 500ms latency

MTU Discovery (RFC1191) = ON
Time to live left = 53 hops
TTL value is ok.

Timestamps (RFC1323) = ON
Selective Acknowledgements (RFC2018) = ON

IP type of service field (RFC1349) = 01000000 (64)
Precedence = Immediate
Delay = Normal
Throughput = Normal
Reliability = Normal
Cost = Normal

DSCP (DiffServ) = CS2 010000 (16) – Class 2 (RFC 2474)
