Upload & connection problem

[Aknosis]

I'm having a weird problem, I can run certain online games perfectly normal but others I lag out within a few minutes, my upload speed seems to be horrible but my download speed is normal. I'm not sure why/how but it's been like this a couple days, my tech support from my ISP is crap so I was wondering if anyone knew of possible errors ...

Windows ME
P3 733
384 mb ram



Browser/OS = Mozilla/4.0 (compatible; MSIE 6.0; Windows 98; Win 9x 4.90)
Note: Read the 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
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:
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 = 46 hops
TTL value is ok.

Timestamps (RFC1323) = OFF

Selective Acknowledgements (RFC2018) = ON

IP type of service field (RFC1349)= 00000000

Well your tweak isn't the problem. It looks great. Someone will be along to look at other things in a bit.

Welcome to Speed Guide.

What type of connection and what are your rated speeds?

[Aknosis]

It's a cable connection, but I'm not sure what you mean by "rated speeds":confused:

[mnosteele52]

He means your ISP's caps, what speed you are paying for or what they advertise as their max speed. If you don't know post a link to your ISP's homepage.:)

[Aknosis]

This is what your talking about then

640Kbps Down and 512Kbps up is what they are advertsising for the plan we bought.

[mnosteele52]

OK great, please read "My Tips" in my sig and follow the suggestions and try the following with the TCPOptimzer:

Settings tab:

select - DSL
check - custom settings
network adapter selection - your NIC
check modify all adapters
maxmtu - 1500
TTL - 64
TCP Receive Window - 7300/8760/11680/14600/23360/39420
MTU Discovery - yes
Black Hole Detect - no
Selective Acks - yes
Max Dup ACKs - 2
TCP 1323 Options - uncheck both boxes*
(* if using TCP Receive Window of 65535 or higher check windows scaling)

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.



:D ;)

Hasn't seemed to change much, but I think I was wrong... my connection must be listed as 3200/512 kbps because I used the speed test with speakeast.net and I got this average after doing the test 10times...
2995.2/57.9

Higest down was 3873 but I got one low of 1655 and the up got as low as 11 and high as 161

[mnosteele52]

Who is your ISP? Your caps determine what size RWIN to use.:)

[Aknosis]

Cable America .. www.cableamerica.com or php.cableaz.com

[mnosteele52]

OK try the following RWINs:

49640/61320/74460/99280/148920/249660 and remember to check windows scaling if using RWIN 65535 or higher.:)

[Aknosis]

Well I can say my upload improved but not by much, when i used the rwin of 49640 I was constantly laggin so I changed to 249660 seems to be like it was before

[Aknosis]

Hasn't changed with any of the Rwins any other possible solutions? Going to see if it's server side which I doubt it would be for so long.
