Hey
I have a 16mb ADSL2+ connection and I get download/upload speeds of about 13mb/1.3mb max. I downloaded TCP optimizer, and at first it seemed like a good tool. What I did:
- I backed up current settings.
- Set the slider to 13mb
- Applied 'optimal settings' and rebooted.
Then I found out my ping had drastically increased in games and ventrilo - making them unusable! Was getting pings of about 100-2500!!! Normally get stable 28 ping on ventrilo.
So obviously this wouldn't do.. so I reverted back to default backed up settings and rebooted. But to my horror the ping was still incredibly high! After trying many positions on the slider and reverting back to standard settings I had no luck, problem still remained.
Have I done anything wrong?
BTW I should mention I used TCP Optimizer to attempt to reduce the occasional packet loss I experience. Please let me know if TCP opti cannot improve this.
Thanks.
PS using Win XP Pro 32 SP3

Ok hope this helps

Your router/modem is being placed near to some strong source of electrical interference, or you have coiled up signal/power cables.Originally Posted by Sundance
Relocate the modem away from other electrical devices and uncoil the cables.

Interesting! My ethernet cable is coiled up as it is too long. Would that be a likely problem?
Set it to 513920 and check Windows Scaling. After that, post your new TCP ANalyzer and tracert.TCP Window: 65535 (NOT multiple of MSS)

Ok here is a test of tracert, speed test and analyzer before and after changing the value:

How are your ping times now?
"Contentment is not the fulfillment of what you want, but is the realisation of how much you already have" - anon
They seem good so far, certainly no radical change like when I applied 'optimal settings'. What should the change in 'TCP Window: 513920' mainly affect? In what scenario could I possibly see the difference? I admit I have only been using PC with new setting for 1 day, so not been able to see any difference so far. Thanks for your help.
TCP Window set to 513920 is to take advantage of Comcast's speedboost which gives a download speed of over 20 mbps in the initial 10 seconds or so. This feature is good only for web browsing.
If you do not have this speedboost feature in your area, you can set TCP Window to 256960.

It might be my imagination but 256960 may work even better. Thanks.
iam using bsnl broadband connect through wifi . but iam facing problem that my internet become slow after 15 or 10 mints .. all downloading and browisng stuck . genrally my speed is 512 kpbs . and i got speed 60kbps from bsnl providers .. and downloding speed goes after 15 mint 30 kpbs to 35 kpbs ... and sometime stuck but strange thing is this when i disable and than enable local area connection in connection setting sped gone agan 60 kpbs . really frustated this happend with me when i used tcp optimizer and i backup setting stil nthing happed plsss help iam fedup
