help with cablenut

tothing · Post by **tothing** » Wed Jan 05, 2005 3:42 am

Mono or other expert here help me set my new isp with cablenut . Im on win XP, and my isp advertised up and down are = 64,384 kbps...
here is the tcp/ip analyzer result

TCP properties for IP = XXXXXXXX.201 ()
Browser/OS = Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)
Notes: Read the Analyzer FAQ if the above is not your IP address.

TCP options string = 0204059801010402
MTU = 1472
MTU is not fully optimized for broadband. Consider increasing your MTU to 1500 for better throughput.
MSS = 1432
MSS is not fully optimized for broadband (although it might work well for slower connections). Consider increasing your MTU value.

Default Receive Window (RWIN) = 17184
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 17184

RWIN is a multiple of MSS
Other values for RWIN that might work well with your current MTU/MSS:
504064 (MSS x 44 * scale factor of 8)
252032 (MSS x 44 * scale factor of 4)
126016 (MSS x 44 * scale factor of 2)
63008 (MSS x 44)
bandwidth * delay product (Note this is not a speed test):

Your RcvWindow limits you to: 687.36 kbps (85.92 KBytes/s) @ 200ms
Your RcvWindow limits you to: 274.944 kbps (34.368 KBytes/s) @ 500ms
Consider increasing your RWIN value to optimize TCP/IP for broadband.
MTU Discovery (RFC1191) = ON
Time to live left = 243 hops

TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349) = 00000000

THANKS

are you on dsl if so is it pppoe ???

Try thease in the sg optmizer below me to download and install also you take another analyzer like you did above after you applied changes and rebooted you need to get that mtu to 1500

select - cable
check - custom settings
network adapter selection -
check modify all adapters
maxmtu -1500
TTL - 64
TCP Receive Window 17520
MTU Discovery - yes
Black Hole Detect - no
Selective Acks - yes
Max Dup ACKs - 2
TCP 1323 windows scailing is checked

Other Settings tab:

Max Connections per Server - 10
Max Connections per 1.0 Server - 20
Lan Browsing Speedup - optimized

Then select "Apply Changes" and reboot to take effect.

1. Under your LAN connection - properties - general tab, uninstall all the protocols there that you do not need.

2. Open IE and select tools - internet options - connections -

LAN settings, make sure NOTHING there is checked.

3. ALWAYS connect your modem via ethernet (NIC) and make sure you have the latest drivers for your NIC from the manufacturer. Set your NIC duplex mode to 10mb half duplex for Cable, for DSL it is ISP dependent unless you are using a router, if so then set it to 100mb full duplex for both Cable & DSL (the instructions are in my Help & Tips link). If you are using a router make sure you have the latest firmware.

4. Clear your temporary internet files.

5. Power cycle your modem, unplug it for atleast 15 seconds.

6. Download and update then do a scan with SpyBot 1.2 http://beam.to/spybotsd & Ad Aware 6.0 http://www.lavasoftusa.com/support/download to remove any spyware then install and update SpywareBlaster to stay spyware FREE. YOU MUST USE BOTH AD AWARE & SPYBOT TO ENSURE YOU ARE SPYWARE FREE SINCE ONE FINDS WHAT THE OTHER MISSES.

7. Make sure you do the faster web page tweak in Read1st link.

8. If you have Zone Alarm as a firewall uninstall it then visit Zonelabs.com for further instructions on removing it's left over junk.

9. Install Outpost Firewall http://www.agnitum.com\ or Sygate Firewall http://www.sygate.com/ , both have FREE and Pro versions and are heads above ZA.

10. Scan for viruses with your antivirus app, if you do not have one get one IMMEDIATELY, AVG 6.0 http://www.grisoft.com/us/us_dwnl_free.php is an excellent FREE AV app.

11. Make sure you have ALL of the latest Windows Updates

When you uninstall Cablenut your settings will revert back to Windows default

thanks.. and thanks so much to mccoffe too, ill tell you latter what happens to my connection

tothing · Post by **tothing** » Thu Jan 13, 2005 9:44 am

my internet speed seem to slow down. I dont know if this is caused by the cablenut setting, and also in game (cstrike) my ping is 500 higher (constant)

. Ive scan couple times with adware (pro) and the lattest spybot ,my panda antivirus, and several online scan, nothing is found.

heelpp
I also try to ping from "run" , all the ping results give "request timed out"

mccoffee · Post by **mccoffee** » Thu Jan 13, 2005 1:44 pm

if you are getting ping time out that could be something on there edn

go to start men run type cmd in the command prompt type

tracert www.speedguide.net cut and paste the resaults

tothing · Post by **tothing** » Mon Jan 17, 2005 12:57 pm

The speed went down for like 3 days, and I found out the problem was from my newb born isp. Its now back to normal, I mean a bit faster ..Thanks mccoffe

tothing · Post by **tothing** » Wed Mar 16, 2005 6:13 am

hi mccoffee, Im back, anywayz now Im back on cable, not adsl anymore due to instability. The advertised speed is 256 kbps and doesnt require username and password to log on to internet. as you know my registry setting is still the same as the adsl setting you gave me above, what should i change in cablenut setting ?. i was wondering if there is a way to reset all to default xp setting and start over again with entering numbers for a cable in cablenut. help please. thank you so much bro!

ps= tips from others are very welcome

mccoffee · Post by **mccoffee** » Wed Mar 16, 2005 3:39 pm

just click on the box delete cablenut settings and save it to registry and reboot.

tothing · Post by **tothing** » Thu Mar 17, 2005 1:08 am

wow that easy! thanks, would you help me with the numbers to put in cablenut for cable ? 256 kbps . thanks

tothing · Post by **tothing** » Thu Mar 17, 2005 1:40 am

mm just to remind you that im on xp, and i also have this question that has been ringing in my head for 4 years. My cable advertised speed is 256 kbp/s, does that mean the speed (on file download window) should be around 256 kbp/s when i download files of internet ? files like movies,songs,game demos etc . I never seen speed on that small window reach above 40. someone please clarify about this advertised speed thing. thanks so much for your time

no 30kbs 256bytes /8 =36bits

OMG now that really answers my question, the whole time i was feel like every isp i subscribed tell a lie lol, but now i know that i get a speed not far below from the promised one, man i never knew that formula, where is the "8" from ?,
btw should i now tweak with tcp optimizer or cablenut ?

TCP options string = 020405b40103030001010402
MTU = 1500
MTU is fully optimized for broadband.
MSS = 1460
Maximum useful data in each packet = 1460, which equals MSS.

Default Receive Window (RWIN) = 17520
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 17520

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 (Note this is not a speed test):

Your RcvWindow limits you to: 700.8 kbps (87.6 KBytes/s) @ 200ms
Your RcvWindow limits you to: 280.32 kbps (35.04 KBytes/s) @ 500ms
Consider increasing your RWIN value to optimize TCP/IP for broadband.
MTU Discovery (RFC1191) = ON
Time to live left = 53 hops

TTL value is ok.

leave it alone your fine

ok if you say so, its just i have this only problem left, i play cs and during the game i sometimes like hang for 3-4 seconds and back to normal, it happened when i was on adsl too, is it because i set the "10 half duplex" thing or .. ?

You're going to have some of those hangs while playing online games, since you only have 384 megs of RAM on a Windows XP machine...you're hitting virtual memory an aweful lot.

Try Speedguides TCP Optimizer instead...and keep your eyes on that page for something new soon.

Ye no mater what program he usues he is still going get lag most games as you know run in udp protocol which is a best effort delivery sorta like my spelling and grammer in most posts, the otpimizer and or cablenut those settings have nothing to do with upd traffic at all none.

edit mtu and time to live is the only two that would effect icmp traffic

He's getting onscreen lagging while playing online games. He has a PIII under 1 GHz, with 384 megs, trying to run a first person shooter game all while juggling WinXP in the background. I'll wager a whole bunch of pints of Guinness that his in-game lags are related to pagefile hits.

Now for further tweaking, was simply suggesting the TCP Optimizer (and soon to come). Not going to help his game much, I didn't say it's help his game in the first place, his game lag is hardware related (under-resourced)

loooool i know my english is horrible, im just trying yo heheheh.. anywayz so thats the cause of the hang ingame screen, omg the price of sdram is incredibly high here because of its scarce ( i forgot the spelling :P) ..arrrr
and mcoffee i havent really got the answer to my main problem bro , with tcp optimizer should i just apply the setting you gave me ? (the one above you tought i was on cbble 384 kbps) or should i just let tcp do it with its optimal settings ? .thanks mac!

mccoffee · Post by **mccoffee** » Mon Mar 21, 2005 8:45 am

I was making fun of my english belive me on that i'm an amercian but i type like i'm five.

Leave your settings alone Yeold is right listen to him it's the only way to fix the lag.

okay

. one more thing i would like to ask is which of the following program that can be safely removed from task manager process ? i think for now this is the only way to save more ram. while gaming
