I've just taken the plunge and installed Win2K onto my PC and need help tweaking the cable internet connection.
Windows 2000 Professional, Pentium III 667 mhz, 256 MB
RAMTCP properties for IP = xx.xx.xxx.xx
Note: Read the FAQ if the above is not your IP address.
Browser/OS = Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)
TCP options string = 020405b40103030301010402
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) = 513920
RWIN Scaling (RFC1323) = 3 bits
Unscaled Receive Window = 64240
RWIN is a multiple of MSS
Other values for RWIN that might work well with your current MTU/MSS:
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: 20556.8 kbps (2569.6 KBytes/s) @ 200ms
Your RcvWindow limits you to: 8222.72 kbps (1027.84 KBytes/s) @ 500ms

Bring up Cablenuts adjuster inside Cablenut on desktop the numbers below go in 3 places in W2k and XP, they are: DefaultReceiveWindow, TcpWindowSize, GlobalMaxTcpWindowSize, take out number that is in there and put in one of these, 1 at a time, try: 522680 or 524176
You do not have to show me but check analyzer here at SG to make sure RWIN is in, you will see number right after (RWIN) on analyzer
At bottom click save to registry, and REBOOT each time you change value in adjuster or it will not work. Click on tools at top of IE, internet options, delete files and offline files (This is safe, temp files) and click on clear history after EVERY test . Fast speed test here
Speedtest may open another browser, so check taskbar and close other, no other programs should be running, No AIM, ICQ, Virus scanner, Firewall, nothing
