ok hehe

yeah i know how to login to the router and change it to 1500...i'll do everything else and post the results here

can't do that vanburen...it's too impractical to bring it all the way downstairs.

i'm sorry to keep replying to my own thread heh...not trying to be egotistical here...

here's a weird thing...when i use TCPOptimizer...it tells my MTU should be 1492:

The largest possible non-fragmented packet is 1464  (1492 - 28 ICMP & IP headers).

You can set your MTU to 1492

It tells my my latency is:

Ping statistics for above hosts:

  Packets: Sent = 15, Received = 12, Lost = 3 (20% loss)

Approximate round trip times (RTT) in milli-seconds:

  Minimum = 19ms, Maximum =  116ms, Average =  54ms

So when I plug that into the RWIN calculator, it tells me 67500 is the best RWIN/BDP...

Isn't that a slow RWIN?  And why would it tell me to only do a 1492 MTU?

very weird...starts off fast..and then gets incredibly slow

this is my new broadbandreports test: http://ttester.broadbandreports.com/tweak/block:593a6d7?service=cable&speed=9999&os=winXP&via=normal

ok...

for some reason...bringing it to 1500 MTU doesn't work and makes it very very slow...but 1492 seems optimal.

how could that be?

Is there a way to find out what my DRTCP settings were before I did anything?

Because neither the old settings nor the ones from what you gave me work now, and I undid cablenut...didn't do anything with the NIC.

The 'old ones' are just what i wrote down the first time i ran DRTCP

:(

yeah...i've been restarting but not powercycling....

weirdest thing...it will start off fast but then get slow when i turn my computer on....but i'm playing around with it

well using your settings of the time it went very fast...the only difference being MTU is 1494...it's now just as fast again.

is tcp receive the same as RWIN?

so it just seems to me...the cablenut tweaks work well when the MTU is 1494...but not when it's at 1500?

ok...what i did was change the MTU back to 1494....and now it's very fast again:

?????????

all i did was go back to the settings you had given me from the time it worked, except with these settings in DRTCP:

tcp receive 64240  path mtu yes

window scaling no  blackhole detection default

timestamping no max duplilcate ACKSs

selective Acks Yes TTL 64

HELP HELP HELP

i don't know what happened...it's now REALLY slow...I tried changing my RWIN in DRTCP and then I ran Cablenut with the optonline settings and now it's

:(

what should i do??? i tried to get back to how it was before but it's still slow

ok i will do that, thanks again 

so using the calculator from this FAQ: http://www.broadbandreports.com/faq/tweaks/5.%20RWIN,

maybe my RWIN should be

btw not sure if this will help, but i pinged ucla.edu (i'm on the east coast, so i picked a west coast college) and i got this

Ping statistics for 169.232.56.135:

    Packets: Sent = 42, Received = 41, Lost = 1 (2% loss),

Approximate round trip times in milli-seconds:

    Minimum = 117ms, Maximum = 140ms, Average = 120ms

optonline says 10,000 Kbps

this is the url: http://ttester.broadbandreports.com/tweak/block:1d5afda?service=cable&speed=9999&os=winXP&via=normal

i had to set the advertised speed to 9999...and i just chose 'normal' cuz i didn't know what to put for connection

thanks so much for all your and everyone's help btw...i very much appreciate it

is the linksys guide which said the MTU thing

dunno why...it's running better than it ever has w the settings you just gave me

yes...do you want me to do another test on that RWIN thing?  you said something about my RWIN is too low?

should i keep going to try to get it better, or is this pretty much it?

OH MY GOD!

how did it get so fast????????????  I just went up over 100 kB/s!!!  :haha:   :D

ok thanks, i will do that

while i'm in the router config, should i change anything else besides PPTP:

Block WAN Request:      Enable

Multicast Pass Through:      Enable

IPSec Pass Through:      Enable

PPTP Pass Through:      Enable 

Remote Management:      Disable 

Remote Upgrade:      Disable 

yeah...i did use DRTCP to undo the MTU change i made and now it's back to 1494.

Do you think I should try that cablenut program?  That was the only thing I didn't do in the list of things to try?

If I was being capped...would I still be able to do speeds much better than I'm doing now?

myriagon:

Normal settings ?

I don't know what you changed it to or back to.

You should set router so it's not on pppoe and set the MTU to 1500 then power cycle PC/MODEM/ROUTER.

Then see how it works.

normal settings meaning, before using that program that swimmer showed me.

myriagon...saw your reply in the other thread...i was under the impression i should keep it here cuz they moved my post to optonline, when it was originally in make me faster....

anyway:

DanM.

Per chance did you used to have DSL on that system?

I have never setup OOL but I'm sure it is cable and it seems like your MSS: should be set to 1460 and your MTU should be set to 1500.

Check your router and make sure it is "NOT" set to pppoe and set the MTU to 1500.

The reason I asked if you had DSL is if you did, make sure that the program that ran it on your PC is completly uninstalled because it may be setting your MSS to 1454.

Also I noticed on another post that you ran a tweak test at broadbandreports and your RWIN should be set way higher than it is.

I hope this all makes sense to you the way I'm wording it.

Let us know what you find out........

EDIT: Also if you change the router settings, make sure you power cycle everything.

no i never had dsl.

i am not sure if i'm on PPoE...i couldn't find that when i connected to my router. PPTP Pass through is enabled, if that means anything?

basic rates is set to 1-2 Mbps...dunno what that is.

i could look something up in my router config if that would help...but there was nothing in the router's config thing that said anything about PPoE

well i should explain that a little...i changed the router and my computer to 1500 and i couldn't go anywhere online (most places timed out), except connect to the router.

i had to set it back to normal settings in order to get the internet working again?  it was extremely slow like that...any ideas why?
