Can you guys help me out?

I did the test and this is what I got. I'm running Win2k with servicepack 2 and IE6.0b. Running PIII 450 with 384MBRAM
Thanks in advance! Oh, and I'm on cable

TCP options string = 020405b401010402010303000101080a00118d9200000000

MTU = 1500
MTU is fully optimized for broadband.

MSS = 1460
Maximum useful data in each packet = 1448, which is less than MSS because of Timestamps, or other TCP/IP options used.

Default Receive Window (RWIN) = 8760
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 8760
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)
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: 350.4 kbps (43.8 KBytes/s) @ 200ms
Your RcvWindow limits you to: 140.16 kbps (17.52 KBytes/s) @ 500ms
Consider increasing your RWIN value to optimize TCP/IP for broadband.

MTU Discovery (RFC1191) = ON

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

Timestamps (RFC1323) = ON
Note: Timestamps add 12 bytes to the TCP header of each packet, reducing the space available for useful data.

Selective Acknowledgements (RFC2018) = ON

IP type of service field (RFC1349)= 00000000

Hey Liquid. First off we need to get a lot more info from ya so that we can help.

1.What are your caps? As in downloads/uploads
2.Did you read all the info here at SG and did you read info elsewhere? Please click on my sig and read everything there first...it is Lobo's help page.
3.Do you have any tweaks in place right now?
4.Do you have the new Cablenut 4.02 program installed on your comp?
5.Who is your provider? This is mainly for me so that if I need to researchsomething for you I can.
6.How are you connected to your cable modem? USB or NIC?

Come back with those answers, make sure you read the info, and we'll be ready to roll and get you up and running at high speeds!!!!

Here the answers:

1. Caps: Up: 128kb/s Down: 10Mbps
2. Gonna read it right away
3. I installed Cablenut & sguide_tweak2k & sguide_webtweak2k
4. Jupperz
5. My provider is Telenet (Pandora) => I live in Belgium. This is their website: http://www.telenet.be (it is in Dutch)
6. No USB that's for sure, Nic than I guess? It is a networkcard in my computer (attached to the Mb)

Thanks

Try these RWIN's (Default Rvc Window)
1 at a time in box on adjuster inside 4.2 on desktop. GlobalmaxTcpWindowSize, TcpWindowSize and Default ReceiveWindow must all contain same number (RWIN), Please try these after you take out number thats there now, try:64240, 385440, 405880,417680 or 420480

Save to registry at bottom and reboot each time you change value in adjuster, check analyzer here to be sure RWIN is in

Win2x only

Tried them (except the last two) but I still got the same thing:

!!!! RWIN stays zero!!!

Set Tcp1323Opts in Cablenuts to 1, save and reboot

I think I ruined everything. I clicked a button and everything was gone...there are no numbers in any of the boxes anymore...can I repair this?

heh, nah...you didn't ruin anything....just reload the CCS file found in the cablenut proggie for cable fast 2K. Reload that, save to registry, and then reboot for changes to take effect. Then come back and redo what Lobo told you to do. Just insure you save to registry each time you make a change. Thats it bro!

Any questions...plz ask!

DefaultRcvWindow - 513920 works the best so far for me.

PIII 450
128MB PC100 SDRAM (soon to be Crucial™ 512MB PC133 SDRAM in a few hours)
Win Me(crap)
2 HD's 30GIG and 13GIG Western Digital

It might on a online speed test but on a actual download of a file or program you may need to go lower, see help page below in signature, 2nd page at bottom on how to do speed test
