I there Knowledgeable people my ISP is Rogers High Speed my down up caps are 1500/192. The problem is my speed has realy slowed down a lot in the last couple of weeks like down to half the speed i should be getting can any one help me please

TCP properties for IP = 63.xxx.x.xxx ()
Browser/OS = Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)
Notes: Read the Analyzer FAQ if the above is not your IP address.

TCP options string = 020405b401010402
MTU = 1500
MTU is fully optimized for broadband.
MSS = 1460
Maximum useful data in each packet = 1460, which equals MSS.

Default Receive Window (RWIN) = 29200
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 29200

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)
128480 (MSS x 44 * scale factor of 2)
64240 (MSS x 44)
bandwidth * delay product:

Your RcvWindow limits you to: 1168 kbps (146 KBytes/s) @ 200ms
Your RcvWindow limits you to: 467.2 kbps (58.4 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 56 hops

TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349) = 11110000

Precedence (priority) = 000 (routine)
Delay = 0 (normal delay)
Throughput = 1 (high throughput)
Reliability = 1 (high reliability)
Cost = 1 (low cost)
