TCP Optimizer - Tips For BEGINNERS

I saw this thread: http://forums.speedguide.net/showthread.php?t=236450

What would TCP Receive window be for 1440 MTU ?

**jasonb31** · 01-30-08, 07:28 PM

Move the slider at the top to match 7mb

Make sure you reset all the changes I recomended, Warning sometimes you have to do it twice in order to get it to stick.

If the optimizer makes my internet worse. How do I restore back my original settings?

**mccoffee** · 02-03-08, 02:59 PM

In the optimizer click on file then should be a reset to default or default settings.

What speed did you pay your ISP to give you?

**mccoffee** · 04-14-08, 01:48 PM

I belive only philip can lock threads ,and maybe some of the mods. You'll have to talk to him about all that.

**DickDiver** · 05-08-08, 04:24 AM

Hi thanks for the guide!

One big question bothers me. Browsing internet by wlan is fine but I have got a network HP printer connected by LAN wire and it prints damn slow.
It is a HP laserjet 2100TN with 8mb or 12mb. Anyway, I used TCPoptimizer and tuned 'only' my WLAN adapter for 1492 PPPOE and 16.000 advertised dl speed.
The question is, have I to adjust the LAN adapter to which my printer connects, too? Is it possible that the printer has problems with a MTU of 1492 or a much too high RWIN?

thanks
DD from Germany

**Rollingstone** · 05-08-08, 07:25 AM

You can try LAN Tweaking : http://www.speedguide.net/read_articles.php?id=1607

**DickDiver** · 05-08-08, 10:31 AM

Thank you Rollingstone

I will try that.

**Philip** · 09-11-08, 08:46 AM

About those two settings:
Max Connections per Server
Max Connections per 1.0 Server

Many web servers do not support too many concurrent connections, setting to a number over 10 can cause problems loading some pages, or excessive repeat requests. I'd recommend setting both to 8 or 10 max.

I was just wondering if you should have a warning about using Optimizer with Vista. Seems the consensus right now is to not use it with Vista.

**dlsayremn** · 09-20-08, 12:44 PM

Someone may have already asked this, but shouldn't you have a cautionary note about using Optimizer and some of the Vista tweaks, esoecially the Autotuning ones, before seeking help? Seems the consensus right now is not to use Optimizer with Vista. Most of the posts I am seeing right now with Vista OS are because Optimizer was used and didn't work or the connection is worse.

I ran Optimizer on my Vista without any real problems last yesr.
Disabled Autotuning, ran Optimizer using custom settings and then enabled Autotuning.
Before doing this I was getting about 800/650 max from speedtedt.net

Previously I've tested the speed both off-peak and peak hour. I live in Malaysia. My friend who subscribed for 384kbps once had a chance to get some 500kbps. I couldn't pass the 3.6Mbps advertised to me. I think i have gained 2mbps or so, but for maybe once or twice. Other than that, it would be an annoying less than 1mbps, and even slower..let alone 3mbps. By the way, modem shows either HSDPA or 3G. Very unlikely to fall below that.

I've tried FullSpeed 3.0, then SC Net Speed Booster before removed them. I did use the SG TCP Optimizer 2.0.3 and followed the guidelines in this website, and forum. But then restored the default windows settings.

I'm very new to the internet , but I know, it's not even half of what i've paid for. Oh, by the way, the speedtest.net shows the wrong location (I don;t know..500 or 600 miles away) where I should be. I read somewhere that says my broadband Plan has a 5gb limitation cap each month.

In advance, I thank you sir.
