Cox -- 5000 down / 768 up - Tried and true cablenut settings needed

Post by orangefibers »

TCP options string = 020405b401010402
MTU = 1500
MTU is fully optimized for broadband.
MSS = 1460
Maximum useful data in each packet = 1460, which equals MSS.

Default Receive Window (RWIN) = 62780
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 62780

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: 2511.2 kbps (313.9 KBytes/s) @ 200ms
Your RcvWindow limits you to: 1004.48 kbps (125.56 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 55 hops

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

:cry:

I have been messing with different setting for the last three hours straight.

My average latency is around 75ms. Could someone please help me with the best settings for cablenut?

My system consists of the following hardware:

P4 3.0GHz
1GB RAM
Cox HI Speed
Usual stuff....

Thanks a bunch guys!!!!

is it just me or are those cable companies offering extreme cable loosing out on latency.

i have 3000/256 and everyone whom ive talked to in my local ISP are had better latency with the old 1500/256

now your posting 5000/768 and your latency is higher yet.


i can only think that with the increased bandwidth the pipes to the isp then to you have become bloated and latency is the first thing to suffer.

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

off topic but

steele how come someone dont update cablenut css files with the latest "optimal" settings for everything.

i just downloaded it and loaded the cable fast setting and it loaded like 8 settings, and none of them were worth a poo. none of the standard settings even showed up.

and once again the "retrieve current settings" does nothing. why ?

how is it suppose ot load the fast cable settings if its not loading the settings.

all it loaded was connections per server,, buffers, and TTL i think none of the other stuff even showed up
