please help tweak my comcast connection

[MaSuTo]

Hi, for some reason my connection is downloading really slow lately and im not sure if it's my computer or the internet. please help me tweak my pc to that it is optimized to cable performance. thanks.

I have a Comcast Cable with advertised speed of 4 Mbps running on Windows XP. My pc is connected to the cable modem which connects to a router to two other pcs.

Browser/OS = Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.7) Gecko/20050414 Firefox/1.0.3
Notes: Read the Analyzer FAQ if the above is not your IP address.
TCP options string = 020405b40103030201010402
MTU = 1500
MTU is fully optimized for broadband.
MSS = 1460
Maximum useful data in each packet = 1460, which equals MSS.
Default Receive Window (RWIN) = 256960
RWIN Scaling (RFC1323) = 2 bits (scale factor of 4)
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)
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: 10278.4 kbps (1284.8 KBytes/s) @ 200ms
Your RcvWindow limits you to: 4111.36 kbps (513.92 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 50 hops

TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349) = 00000000 (0)

Try thease in the sg optmizer below me to download and install

select - dsl pppoe
check - custom settings
network adapter selection -
check modify all adapters
maxmtu 1500
TTL - 64
TCP Receive Window 64240
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 http://beam.to/spybotsd & Ad Aware 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

[Cronicus]

The formula for finding your "ideal" RWIN, is to take your latency (average ping time in ms x 1.5), multiply that by your advertised (download) speed, and divide that by 8.
example of mine
100ms
x
1.5
-------150

150
x
6223 but well just say 6000 to prevent overload
-------900000

900000
/
8
----112500 <--------ahhahahhahahha

[mccoffee]

again show me any documentation or something other then posting your two cents i could give everyone here links to rfc's or white papers

[Cronicus]
