Go here (http://www.speedguide.net/) and post your TCP/IP results. BTW... remove your IP number.

TCP options string = 020405b4
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) = 49152
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 49152
For optimum performance, consider changing RWIN to 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: 1966.08 kbps (245.76 KBytes/s) @ 200ms
Your RcvWindow limits you to: 786.432 kbps (98.304 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = OFF
Time to live left = 52 hops
TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = OFF
IP type of service field (RFC1349)= 00000000
29352 connections tested since 03.10.2001.
Analyzer version: Beta 0.99
Go below in help thread for directions on how to disabled proxy:)

Proxy is not disabled, anytime you see after RWIN 49152 that means proxy is enabled, you must REBOOT after you disable:)
