Comcast Cable Tweaking?

[w1tth4y4]

Hello, im new all to this stuff. I have Comcast Cable and the internet is not stable, My internet just disconnect rapidly, so i thought it would need some Tweaks, but i do not know what to do to start off. So I beg some of you could help me make my internet stable. . Here is my TCP/IP Analyzer
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 = 52 hops

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

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

General Settings tab:
Custom settings - check
Modify All Network Adapters - check
network adapter selection - your NIC
MTU - 1500
TTL - 64
TCP Receive Window - 64240
MTU Discovery - Yes
Black Hole Detect - No
Selective Acks - Yes
Max Duplicate ACKs - 2
TCP 1323 Options:
Windows Scaling - uncheck
Timestamps - uncheck
Advanced Settings tab:
Max Connections per Server - 10
Max Connections per 1.0 Server - 20
LocalPriority - 5
Host Priority - 6
DNSPriority - 7
NetbtPriority - 8
Lan Browsing speedup - optimized
QoS: NonBestEffortLimit - 0
ToS: DisableUserTOSSetting - 0
ToS: DefaultTOSValue - 240
MaxNegativeCacheTtl - 0
NetFailureCacheTime - 0
NegativeSOACache Time - 0
LAN Request Buffer Size - 32768
Then select "Apply Changes" and reboot to take effect

VERY IMPORTANT TO DO THE FOLLOWING:
1. Under your LAN connection - properties - general tab, uninstall all the protocols there that you do not need. For a stand alone pc all you need is Internet Protocol TCP/IP.
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 and set your duplex mode to "auto". If you are using a router make sure you have the latest firmware.
4. Clean out your temporary internet files with CrapCleaner (http://www.ccleaner.com).
5. Power cycle your modem i.e. unplug it for at least 15 seconds.
6. Download, update and scan with SpyBot S&D 1.4 (http://majorgeeks.com/download2471.html) EXACTLY as mnosteele has explained HERE (http://broadbandnuts.com/drtweak/index.php?board=4;action=display;threadid=41) & Ad-Aware SE 1.06 (http://lavasoft.element5.com/support/download) EXACTLY as mnosteele has explained HERE (http://broadbandnuts.com/drtweak/index.php?board=4;action=display;threadid=40) to remove any spyware then install and update SpywareBlaster 3.4 (http://www.javacoolsoftware.com/spywareblaster.html) to stay spyware FREE. YOU MUST USE BOTH AD AWARE & SPYBOT TO ENSURE YOU ARE SPYWARE FREE SINCE ONE FINDS WHAT THE OTHER MISSES. If these 2 programs find a lot of things then please post a HijackThis 1.99.1 (http://www.majorgeeks.com/download3155.html) log for us to look at.
7. Make sure you do the faster web page tweak in our Help & Tips (http://broadbandnuts.com/index.php?page=tiptrix) page.
8. If you have Zone Alarm as a firewall uninstall it and search your pc for the left over files.
9. Install Kerio Personal Firewall 2.1.5 (http://www.321download.com/LastFreeware/page7.html#Kerio%20Personal%20Firewall), it's FREE and uses next to no resources.
10. Do a FREE online virus scan from Kaspersky Webscan (http://www.kaspersky.com/beta), make sure to check the option to use the EXTENDED DATABASE.
11. Make sure you have ALL of the latest Windows Updates.

My internet seem to be loading slower =( I thought it will go faster. So what should i do Mr.?

[mccoffee]

what were your speeds before also try 128480 for default recive window with windows scaling checked.

[w1tth4y4]

I'm not sure what was my speed. Isnt my speed on the top post?

[mccoffee]

nope that isn't a speed test

[w1tth4y4]

The speed before was
Download Speed: 824 KB/sec transfer rate
Upload Speed: 89.5 KB/sec transfer rate

[mccoffee]

what's the speeds with the 64240 or the 128480 if slower go back to the 256960

[w1tth4y4]

alright.
