Ok, i need the values for a friend, here is his info: XP, DSL, Router, Bellsouth as ISP.

Yea, i know what your gona say, change the MTU to 1500/1492 [im not sure if its ppoe or not], well it is changed. But the router limits it, any way to change the setting in the router too?

TCP options string = 020405a401010402
MTU = 1484
Unrecognized MTU, or MTU = 0.
MSS = 1444
Maximum useful data in each packet = 1444, which equals MSS.

Default Receive Window (RWIN) = 65340
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 65340

For optimum performance, consider changing RWIN to a multiple of MSS.
Other values for RWIN that might work well with your current MTU/MSS:
508288 (MSS x 44 * scale factor of 8)
254144 (MSS x 44 * scale factor of 4)
127072 (MSS x 44 * scale factor of 2)
63536 (MSS x 44)

bandwith delay product:

Your RcvWindow limits you to: 2611.2 kbps (326.4 KBytes/s) @ 200ms
Your RcvWindow limits you to: 1044.48 kbps (130.56 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 112 hops

bandwidth * delay product:

Your RcvWindow limits you to: 2613.6 kbps (326.7 KBytes/s) @ 200ms
Your RcvWindow limits you to: 1045.44 kbps (130.68 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 112 hops

TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349) = 00000000

Make sure the router has the latest firmware and set it's MTU to 1492. Also did you do the fix here?

After the conection was disabled, the delete button was grayed out [on the right click menu].

He is refering to

Your connection should be under Broadband Connections. Right click >disconnect, then right click > delete.

Correct.

Let's eliminate the router as the issue, when you bypass the router what is your MTU?
