As the title indicates, I would like to increase my upload speed. I do have cablenut 4.08 installed but rather then mess with it myself, i decided to go to the experts.

1. What type of connection do you have? i.e. 56K, ISDN, DSL (PPPoE or not), Cable etc.
I am running Cable


2. Who is your ISP and what is your advertised speed from them? i.e. Cox.net & 3000/256 - this is advertised in kilobits per second.
Charter Communications 1500/768

3. What are your current settings now? Do a TCP/IP Analyzer test and copy and paste the results (remember to XXXXX out your IP address) here.
TCP properties for IP = xxx.xxx.xxx.xxx ()
Browser/OS = Mozilla/4.0 (compatible; MSIE 6.0; Windows 98; Win 9x 4.90; YComp 5.0.0.0)
Notes: Read the Analyzer FAQ if the above is not your IP address.

TCP options string = 020405b40103030401010402
MTU = 1500
MTU is fully optimized for broadband.
MSS = 1460
Maximum useful data in each packet = 1460, which equals MSS.

Default Receive Window (RWIN) = 1000000
RWIN Scaling (RFC1323) = 4 bits (scale factor of 8)
Unscaled Receive Window = 62500

For optimum performance, consider changing RWIN to 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:

Your RcvWindow limits you to: 40000 kbps (5000 KBytes/s) @ 200ms
Your RcvWindow limits you to: 16000 kbps (2000 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 114 hops

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


By the way, I must mention that someone on this shared family computer, someone has been screwing with drtcp so the rwin number is a little messed up.

4. Please tell us your operating system i.e. 95, 98, 98SE, ME, 2K or XP.
Windows Millenium Edition (ME)

Welcome to Speedguide jlloyd:cool:, I would agree that your RWIN is messed up. Just FYI, you can't tweak your upload but having a ridiculous RWIN as you do will slow your upload. In any case use the following settings in CableNut:

BcastNameQueryCount - 1
BcastQueryTimeout - 100
BSDUrgent - 1
CacheTimeout - 600000
DefaultRecvWindow - 37960
DefaultTTL - 64
EnableDNS - 0
GlobalMaxTcpWindoSize - 37960
KeepAliveInterval - 500
KeepAliveTime - 14400000
Lanabase - 0
LocalCopyMade - 1
MaxConnections - 100
MaxConnectRetries - 5
MaxDataRetries - 64
NameTableSize - 255
NameSrvQueryTimeout - 100
PMTUBlackHoleDetect - 0
PMTUDiscovery - 1
RoutingBufSize - 146432
RoutingPackets - 100
SackOpts - 1
SessionKeepAlive - 7200
SessionTableSize - 255
Size/Small/Medium/Large - 3
Tcp1323Opts - 0
TcpTimedWaitDelay - 30
MaxDupAcks - 3
DefaultTOS - 240
IGMPLevel - 2
MaxConnectionsPer1_0Server - 20
MaxConnectionsPerServer - 10

VERY IMPORTANT TO DO THE FOLLOWING

1. Under your Configuration tab for your Network settings make sure you have only the needed protocols.

2. Open IE and select tools - internet options - connections - LAN settings, make sure NOTHING there is checked.

3. 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 (http://forums.speedguide.net/showthread.php?s=&threadid=73799)). 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 (http://www.wilderssecurity.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.

7. Make sure you do the faster web page tweak in my Help & Tips link (http://forums.speedguide.net/showthread.php?s=&threadid=73799).
