ok superman and McCoffee any new suggestions?
thanks

2005-01-26 14:40:19 EST: 3563 / 356
Your download speed : 3648777 bps, or 3563 kbps.
A 445.4 KB/sec transfer rate.
Your upload speed : 365184 bps, or 356 kbps.

************************

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

Default Receive Window (RWIN) = 75920
RWIN Scaling (RFC1323) = 1 bits (scale factor of 2)
Unscaled Receive Window = 37960
RWIN is not fully optimized (even though it is a comparatively large number). The unscaled RWIN value is lower than it should be, which can affect your connection to some servers. Also, RWIN being close above 65535 does not justify the header overhead of scaling. You might want to use one of our recommended RWIN values below.

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: 3036.8 kbps (379.6 KBytes/s) @ 200ms
Your RcvWindow limits you to: 1214.72 kbps (151.84 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 54 hops

TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349) = 11110000

Precedence (priority) = 000 (routine)
Delay = 0 (normal delay)
Throughput = 1 (high throughput)
Reliability = 1 (high reliability)
Cost = 1 (low cost)

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

select - cable
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 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

Comcast just pushed the new config files a few minutes ago. I have the Gold service so I am now cruising along at 6000/768

Reg plan, 3000/256

Standard service is now 4300/384 and upgraded tier is 6300/768.

4000/384

4.0Mbps speed refers to downloads only, maximum upstream: 384Kbps. All speed comparisons are for downloads only. Faster speed claims compared to Comcast's previous 3.0Mbps standard residential High-Speed Internet services. Speeds for customers previously subscribing to 4.0Mbps/384Kbps plan have been automatically increased, to as fast as 6Mbps/768Kbps at no additional charge. Actual speeds vary and are not guaranteed. Many factors affect speed
