What RWIN will be good for my upgrade? EA yes it finally came through.

Im 4,800ft from the CO...
Windows 98se
750Mhz Duron
128 PC 133 RAM
Geforce2MX 32MB
Verizon DSL 1.5/128
Linksys LNE100TX Fast Ethernet Adapter(LNE100TX v4)
Enternet 300

TCP options string = 020405ac0103030001010402

MTU = 1492
MTU seems to be optimized for PPPoE... If you are not on a PPPoE connection, consider increasing your MTU to 1500 for optimal throughput.

MSS = 1452
Maximum useful data in each packet = 1452, which is equal to MSS.
MSS is optimized for PPPoE. If you are not on a PPPoE connection, consider increasing your MTU value.

Default Receive Window (RWIN) = 63888
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 63888
RWIN is a multiple of MSS
Other values for RWIN that might work well with your current MTU/MSS:
511104 (MSS x 44 * scale factor of 8)
255552 (MSS x 44 * scale factor of 4)
127776 (MSS x 44 * scale factor of 2)

bandwidth * delay product:
Your RcvWindow limits you to: 2555.52 kbps (319.44 KBytes/s) @ 200ms
Your RcvWindow limits you to: 1022.208 kbps (127.776 KBytes/s) @ 500ms

MTU Discovery (RFC1191) = ON

Time to live left = 50 hops
TTL value is ok.

Timestamps (RFC1323) = OFF

Selective Acknowledgements (RFC2018) = ON

IP type of service field (RFC1349)= 00000000

Your download speed : 1294104 bps, or 1294 kbps.
Browsers would show : about a 157.9 k/sec transfer rate.
Your upload speed : 113798 bps, or 113 kbps.
Your connection rocks .. above the 1mbit barrier!

I don't know the right RWIN but EA will as he's on DSL, but their are alot of members signing on here using different names and playing with people, if you think this is happening to you report it to the Mods and have person use search function

Hey SSky11, nice to know it finally came through. You can try these RWINs, let me know which one works best for you. 92928, 130680, 139392, 174240, 185856, 217800, 232320, 255552, and 261360. Good luck

Try these for fun, first we'll have to turn timestamps off. In the adjuster set Tcp1323Opts to 0 or just leave it blank.
Try 20328, 23232, 26136 and 29040 while Tcp1323Opts is set to 0 or blank. Set it back to 1 when trying the above RWINs or anything higher than 65535. Once again, good luck! Have fun testing. Mine comes July 2nd... I hope I get it then because I'll be on vacation starting July 10th. I may be out the whole summer...
