Can I know my broadband downloading speed with this tool and connection speed also?

nope..go to speakeasy for that

Philip
Thanks for the new version, but think I will stay with your last version. My download speeds on Direcway's DW4000 is between 1500 and 2200 Kbps. Old saying if it works don't fix it. Yes your TCP optimizer does work.

I used the TCP Optimizer. Before use I was running at 30% of what I should have been on Road Runner.

After running it I am @ 60% above.

Took all of 10 minutes.

Truly remarkable.

Thank you, I just launched the optimized settings and as far as I seen it tweaked a lot the previous settings. It's strange because I ran previously TweakMASTER. Why that?



Regards,

Hi,

I've got ADSL2+. The advertised speed is 24000Kpbs but my router only syncs at 9500. What speed shall I indicate to TCP/IP Optimiser?

Cheers

thanx

I'd use 10 Mbps (10,000 kbps).

Receiving this error when I try to install. Illegal instruction.

Hi.

I used the program and after rebooting couldn't connect to some sites.

Only about 1/3 of my speed tests even worked at all. Most would lock up my browser (IE).

Restored my backup from the software, uninstalled, rebooted, and now everything is fine.

Be careful

No point in doing all of that and there is nothing to uninstall. Simply open the TCPOptimizer and select File - Restore Windows Default Settings.

Hi.

That IS exactly what I did, a restore from within the TCP program. Then I uninstalled the thing since it only made things worse.

The TCP Optimizer doesnt install, so you can only delete it. Theres no listing in add/remove programs to uninstall it.

Oops. I should have said 'deleted' from my hard drive the whole time. Sorry for my incorrect information.

Ran the TCP Optimizer on my nephew's computer, (it was his b-day party today) Windows 98 SE on a Pentium 3 @ 800 MHZ / 256 msgs of ram. Comcast Cable. Before, speakeasy speed test was showing a little bit over 2 megs down. After running the TCP Optimizer, over "4" Megs down. Awesome! Then people started coming up to me at the party and asked what I did for the speed increase.

*insert TCP Optimizer and Speedguide plug here*
"Where do I get that app from? What site is that?" people asked. "Speedguide.net" I said. "This is where I hang out.. you can learn a bunch of stuff about computers, go the the forums, become a member ECT.." I added.

Hi,

I have run this program on my PC and I can't believe how my speed has increased dramatically.
However my ISP announces connection speed 30 Mb (download : 30720 kbit/s IP and
upload: 1024 kbit/s IP , I am on TV cable internet). Since the maximum connection speed that can be specified using this tool is 20 Mb, I can only use this maximum value or did I make mistake understanding the value?
I wonder if my connection can go faster if the sliding menu can reach 30 Mb.
I am happy already with this 20 Mb (it was shown on the speed test), however I wouldn't mind if it can go to 30 Mb

Nice tool….. Thanks

I'm at a download speed of 3550kbps. Should I set the Tcp optimizer at 4000kbps or 3500?

You would set TCP Optimizer at 4000 Kbps since it seems like you are capped at 4Mbps.

Thanks for the info.

Oh My...Thank you so much whoever made this program...I have been working with my cable company for a week to try to figure out why i was only getting 1.5 megs down when I was paying for 3.0 megs down...I kid you not...I found you guys forum..I saw this program. I downloaded it an ran it ran the optimum settings for my connection..And ahh be danged if as soon as I rebooted my computer got back online and did a speed test 3.1 megs down..Freekin awesome..Whoever invented this one if you were in my town..My friend me and you would be eating a big fat steak paid for by me..You saved me from making more of an idiot out of myself...THANK YOU>>>>

Glad it worked that well for you, and thanks for sharing

This site has always been about helping broadband users, and actually being able to motivates us and keeps us going

Tried DRTCP, Cablenut, Tweakmaster, TweakDun plus other tweaks. This one works best. Found setting the MTU for PPPoE to 1452 - not the recommended 1492 - provides more stability (no dropouts) and more consistant speeds.

Thanks! Great work.

the settings shown when choosing the optimal setup for my connection speed are less then wat my current values are.. so should is still apply them or should i retain the current ones as the internet may go slow after applying the settings?

I'm using the Sprint EVDO network for access and have the Pantech PX500 Rev A card but Rev A hasn’t been turned on in Buena Park (Los Angeles) CA but my upload and download times have been acceptable with signal strength between -71dBm to -83dBm but I think I can do better if my latency (ping) times were lower. I have downloaded and ran TCP Optimizer 2.0.3 which helped my speeds but latency times have always been consistently high and I'm looking for suggestions to lower those times. I'm using a 2005 Toshiba-XP(SP2)-1gb RAM and no spyware or viruses.

Thanks ahead of time for the help.

Please start a separate thread if you're asking about help with current settings. This thread is intended for comments/bug reports/suggestions about the TCP Optimizer program. TIA

Excellent program, but one request : could the Largest MTU tool be tweaked to avoid using 1125 or any other odd-length packets, as a known bug involving Intel cards and Cisco routers causes such packets to time-out ?

i go to use the largest MTU option in the optimizer and it times out when sending 1456 bytes and fragments when sending 1476 - what does this mean?

Good stuff Philip. It just keeps getting better and better!!!

Hi,
I just downloaded this program and when I ran it, a lot of the text is missing (labels) from the GUI screens(menu's). The buttons are not labelled. Almost all the selectable items are grayed out. I am using XP sp2. Any suggestions? I tried it on my Windows 2000 machine and the menu's have their labels.

On Vista, the title bar reads Windows 2000. Given the fact the IP stack is rather different, is an updated version of TCP Optimizer needed/planned?

Is there any real need to monkey with tweaking programs? IMHO, if you simply set MTU at 1500 and RWIN at 128480...your computer is fully armed, loaded and ready to handle anything Internet related.

Recently (meaning just last night) I had a service tech from Embarq trying to get my speed up to where I have been $$$$ for at 5000 kbs DSL...he even brought his laptop thinking it was my computer just to eliminate the possibility. Best he could do was about 3000....Frustrated but his time was up...end of the day..he left. After he left I miraculously found this forum and the TCP Optimizer WOW is the best way to explain myself Thanks to who wrote this program....I am getting 4700 consistently. GREAT TOOL!!!! Now I think I will charge EMBARQ!

Thanks for the positive feedback xonmob1, we try


zatnkatel: We're planning on updating the Optimizer for Vista, just that the underlying tweaks are not yet available/tested. Vista is better optimized for broadband by default, I'd wait for something reliable before tweaking it.

shoreke: You're right, those are the main settings, but some others help as well. Each setting in the Optimizer has its purpose for fine-tunning your connection - it's explained in the documentation, and some of the tweaking articles on the main site.

I'll see if i can try it and see if there is any improvment on my internet. I am using dsl btw

thanks for share.

can any one tell me what to do after installation,means setting to be change,
yes i use bsnl(india)dataone broadband service.my modem is ut starcom(UT300R2U.

Post a new thread with your TCP Analyzer report. Also tell us what speed you have paid your ISP to give you.

Is Speedguide going to update there program to work with Vistas new TCP/IP stack??
