kindredmwa · Post by **kindredmwa** » Wed Feb 13, 2002 1:22 pm

I just installed cablenut .08 over the existing .02 and it erased my previous settings.I had 578160 as my rwin and i re entered it but it doesnt register on the analyzer....i forgot what to do to get it to work properly....Any help on how to get it back to my old settings would be great!Im running XP pro with 512 ddr,amd 1.4 tbird... Here is my results now..Im on comcast cable....

TCP options string = 020405b401010402

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) = 64240
RWIN Scaling (RFC1323) = 0 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)
256960 (MSS x 44 * scale factor of 4)
128480 (MSS x 44 * scale factor of 2)

bandwidth * delay product:
Your RcvWindow limits you to: 2569.6 kbps (321.2 KBytes/s) @ 200ms
Your RcvWindow limits you to: 1027.84 kbps (128.48 KBytes/s) @ 500ms

MTU Discovery (RFC1191) = ON

Time to live left = 37 hops
TTL value is ok.

Timestamps (RFC1323) = OFF

Selective Acknowledgements (RFC2018) = ON

IP type of service field (RFC1349)= 00000000

Enter 578160 in Tcp Window Size and GlobalMaxWindow Size

save to registry and REBOOT

Ok,did that and this is what it says now,what next?I applied the fast cable settings first.....is that the problem?I remember something about the scaling if im not mistaken...thanks for the help,you da man!

Default Receive Window (RWIN) = 65535
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 65535
Note: Under Windows 9x, if you have RWIN set to any other value, and the Analyzer reports 65535 you might need to install the MS Vtcp386 fix.
For optimum performance, consider changing RWIN to a multiple of MSS.

All Cablenut settings are for RWIN 64240, if you do not use that RWIN the setting do not apply to you, Click on clear all boxes at bottom to get you back to Windows defaults, save to registry & REBOOT, after do the above

Also try these tcp Window sizes in GlobalMax too: 584000, 589840, 607360, 642400

OK,went back to defaults and applied the #'s to GlobalMaxTCPWindow Size,Default receive window and Tcp Window Size...all the other boxes are cleared....still not the same as before...

Put a 1 in box that says Tcp1323Opts to allow scalling, save to registry and reboot

that did it!Thats the problem i had before....thanks alot!What other tweaks would you suggest in cablenut?buffer stuff etc..?Thanks again for the help!Ill write all this down for next time so i dont have to bother you!

Read these posts and see what works best for you, tell me where you live so I can tell you where to speed test, read how to in sig

kindredmwa · Post by **kindredmwa** » Wed Feb 13, 2002 2:46 pm

ok,I live in Huntsville Alabama.Just switched from comcast@home to comcasts own internet service today...Im familiar with speed tests but not with the tweaking part of it.Comcasts new software installs this program called "Client Foundation",do you know if its safe to remove/uninstall?I got Zonealarm to block it with no trouble....Thanks for the quick responses.

Lobo · Post by **Lobo** » Wed Feb 13, 2002 2:48 pm

Why do you use Zone alarm when XP has built in firewall, and I never heard of other

kindredmwa · Post by **kindredmwa** » Wed Feb 13, 2002 2:51 pm

I didnt think xp's was as good as zonealarm.Ill try setting up XP'S and try it....If you find out info on Client Foundation software or any other reader knows if its required please let us know.Im searchin google for more info on it now...

Lobo · Post by **Lobo** » Wed Feb 13, 2002 2:53 pm

I use XP's, Zone alarm is good but uses resourses thus you are slower

kindredmwa · Post by **kindredmwa** » Wed Feb 13, 2002 3:00 pm

cool ill set it up and try it

Lobo · Post by **Lobo** » Wed Feb 13, 2002 3:07 pm

Disabling Zone alarm does not keep it from running in background, you have to go to control panel and add/remove it, uninstall

kindredmwa · Post by **kindredmwa** » Wed Feb 13, 2002 3:17 pm

yeah,i did that,set up xp's and alls weel so far.thanks.

I un-installed CF works fine so far. I wish I hadn't installed to start with it brand my IE and OE. THey will send you the manual settings in mail to set up your email after about a week.

Thanks alot,I uninstalled it just now,no probs.That branding does suck....
