:1. Go to top of page and click on TCP/IP Analyzer
2. Copy all this by highlighting everything in box with mouse
(you may have to make box smaller. To copy contents of box, highlight, then hit Ctrl & c, on your keyboard, when you return to Speedguide in reply box, with cursor blinking, hit Ctrl & v, this will copy contents in box so I may look at it. Thank you.
X out your IP Address

TCP properties for IP = xxx.xxx.xxx.xxx
Note: Read the FAQ if the above is not your IP address.

TCP options string = 020405b40103030201010402

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) = 256960
RWIN Scaling (RFC1323) = 2 bits
Unscaled Receive Window = 64240
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)
128480 (MSS x 44 * scale factor of 2)
64240 (MSS x 44)

bandwidth * delay product:
Your RcvWindow limits you to: 10278.4 kbps (1284.8 KBytes/s) @ 200ms
Your RcvWindow limits you to: 4111.36 kbps (513.92 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

Patch is in, looks good, how much RAM (Memory)
do you have?

darentanyp · Post by **darentanyp** » Tue Mar 27, 2001 10:33 am

p3-500
ram is 128mb x 2 (133mhz)
64mb x 1 (133 mhz)
all kingtons
hdd is quatum 15gb
soundcard - creative 128pci
i believe it is not my computer configuration but the setting of the inf files

or maybe Win ME
i was using a prolink 1456 v90 modem ,
also using getright for download as well as ie 5.5 for browing
sigh can some one help me just write the inf file for me to revert to nothing or maybe the value set for cable during download take up all resources.

If you would like to return to default run our back to default patch on patch page, this site, it will only take out settings that speedguides patch put in
