Cablenut settings for Rogers cable

[khriez]

1) I have cable
2) ISP is Rogers High Speed internet the advertised speed is probably 3000/300ish. Here is my speed test results at NYC if it helps:

2004-07-12 07:51:38 EST: 2203 / 356
Your download speed : 2256475 bps, or 2203 kbps.
A 275.4 KB/sec transfer rate.
Your upload speed : 364664 bps, or 356 kbps.

3)
SpeedGuide.net TCP/IP Analyzer


TCP properties for IP = xxx.xxx.xxx.xxx ()
Browser/OS = Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; YComp 5.0.0.0; .NET CLR 1.0.3705)
Notes: Read the Analyzer FAQ if the above is not your IP address.

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) = 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 (Note this is not a speed test):

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 = 117 hops

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

4) Operating system is XP HOME EDITION.

P.S. I have done some previous tweaking but I did a system restore but for some reason my downloads went faster !? I do believe I can get a better score than this, thankxs.

Give thease a shot just fyi though you are gettting your average from that provider try thease

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\ (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

Hmm didn't really notice any improvement in the speed tests, kinda went slower, unless its their server.

Try thease in cablenut to get back to where you were you are seeing what you are suppose to accoriding to shaw's faq


GlobalMaxTcpWindowSize 64240
TcpWindowSize64240
Tcp opts123 0

AHhh forgot to mention, I have a network, 2 computers sharing 1 rogers cable connection, if that helps ??

[mccoffee]

I don't think that's effecting your speed like i said you are getting the average

[khriez]

I got another question for the downloads, it would start at 600 kb/s drop all the way down to 400 kb/s, then 350 kb/s, 280.....250.... slowly going down even more then speed increases again then stays around 170 kb/s depending on server.

that is the way tcpip is designed it suppose to do that. the leveling is the actuall speed

SmallBufferSize = 12800
Hiya McCoffee. Is this line a typo? I noticed that most of your settings were similar to the template Cable & DSL 3000 384.ccs. But for this particular setting, the SmallBufferSize = 1280. Just wondering if that extra zero is intentional or a typo. Thanx!

[mccoffee]

12800 this is the right one i have seen it both ways though i might ask dannjr at cn about that.
