tired of slow internet? follow these steps to get a fast internet experience!

1.   Go to desktop->
My computer-(right click on)->properties->
then go HARDWARE tab->
Device manager->
Now u see a window of Device manager then
go to Ports->
Communication Port(double click on it and Open).
After open u can see a Communication Port properties.
Go the Port Setting:----and now increase your "Bits per second" to 128000 and "Flow control" change to Hardware.
Apply and see the result.
2.   click START > RUN > type  gpedit.msc
go to local computer policy > administrative templates > network > QOS PACKET SCHEDULER > double click LIMIT RESERVABLE BANDWIDTH , it will say it is not configured, but the truth is under the 'Explain' tab
click enable then set the value of bandwidth to "0" ZERO.
3.   click START > RUN > type  gpedit.msc
go to local computer policy > administrative templates > network > QOS PACKET SCHEDULER > background intelligent transfer service > double click MAXIMUM NETWORK BANDWIDTH THAT BITS USES (BITS - Binary Intelligent Transfer Service, BITS uses HTTP. BITS downloads files using the standard Hypertext Transfer Protocol (HTTP) and requires Internet Information Server (IIS) to be running on the server that serves the files. HTTP packets pass more easily through firewalls, which makes BITS a good choice for getting files from the Internet.)
choose enabled
limit bits transfer rate to ?0?
from 12:00am
to 12:00am
check use all available bandwidth
4.   now for the last part
go to start>run>regedit>then go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\Tcpip\Parameters

right click anywhere in the right side of the window then select NEW DWORD, then input the dword name, after the new registry entry is made, double click it and input the dword value.

Works best in windows xp GOOD LUCK!

I guess it wouldn't hurt if I gave it a shot. I'll tell you what if I see any improved results.  :)

Thanks for the tips, will do and hopefully see faster internet speeds.  ;D

Looks very interesting. Will give it a shot. Thanks!

Hello,

Could you explain what it is supposed to do, on which operating systems, and why all the replies so far seems to be very happy with that...

Everyone say they would give it a go, but no one comes with a feedback... Maybe they just crashed their computers trying to copy and paste the code provided ?

Thanks and Merry Christmas nonetheless !

Hi,

First of all, Merry Xmas.

Wanna ask: Is that this stuff best for Win 7 too rather than xp?  ???

Thanks.  ::)

I am yet to try out this tips. But does this apply to window 7 or other operating system?

Sounds risky. :-\ I'm not trying it.

Yeah, this sounds suspicious. I wouldn't take the chance either.  :-\

Really useful ....Thank! I am going to give it a shot now ;D

Win XP or 7?  ???

I have tried this thing in Win 7 and it works marginally.Actually,I got these commands from support staff of my Internet connection provider.While editing the system file, be sure to keep a back up copy if u r nt sure abt anything.

I'm not taking the risk.  :-\ TS should post more details as to what operating system he's referring to.

It is something new i will try and will post resolt
thank you any way

has anyone tried this?

Nice one. Hopefully, everything would turn out well.  ;)

I'm waiting for the folks to post results like they said they would. It is mentioned works for Windows XP but I'm wondering about other OS's.

I do it exactly as you wrote but it does not work for me  :-[

This one sounds very interesting..Did  anyone give it a try  yet?
Does it really work? I am too afraid to ruin my computer by giving it a try myself lol
BTW Thanks for sharing

Not sure why it is not working for me and I was wondering if maybe I did something wrong?

Does it work with Win 7? sounds interesting to me
Please let me know if this works
appreciate!

Wow..that sounds very interesting..I am gonna try it now and will get it back to you guys for the result
Thanks! :)

Thanks for the tips. but does it work for windows 7?

I tried it actually. And I definitely seeing the same that you are seeing it.
Thanks for the new idea!

Hey guys, does this really work???

I can't apply it on Win 7 32bit and try it on Win 7 64bit too.!  ??? Does anyone have same problem like me, guys.?

Pretty Cool! Has anyone noticed a big difference ?

Would it be possible on Windows Vista? I used to use 3g internet dongle and it was painful!!! Now I'm using 02 broadband and the internet is faire fast. :) But the computer can be a problem sometimes. I need to download and upload most of my time on the web :)

I couldnt get past step 1 on my Ubuntu box   :)

I am sick of my computer going so slow.  >:(.

Being a novice, this looks quite complicated but I will follow the instructions and see how I go..

Thanks for the post.

I have Windows 7 and I don't think I will take the risk if it only works marginally.  Thank you for the update!

Thanks great info. Interesting

thanks for info

Thanks, we shall see how this goes!

It made a noticeable difference on my windows 7 system.  :)

Works best in windows xp GOOD LUCK!

Thanks for the great tips it is really useful but only on xp

I was sick of slow internet speed but these tips are very good to use and very informative

Doesn't the speed depend on how old your computer is and how much software you have downloaded on it as well? Just curious...because I noticed that was happening to me as I added more software that I actually needed to perform certain functions on my computer (an older version), I just had to get a newer computer with more RAM...had the same amount of software installed, by the slowness disappeared.

Michael

Thanks! I may be changing internet service providers, I will try this today to see if this helps with some of the lag I am getting.

Thank you again.

Hey that really looks like something worth giving it a go.

I have the need for speed.  ;D

Will it also work in windows 8?

awesome bro,
i try it , its working like a charm.

All you're doing here is enabling "Jumbo Frames" and then setting your windowing to make use of them. That's all fine and well until you plug into a router/switch/modem that doesn't support non-standard frame sizes, at which point your traffic becomes unroutable. While Windows 7 does have some TCP window size auto-adjust out of the box it is very buggy and often does more harm than good to performance. The steps listed by the OP will help sequential file transfer speeds but will likely hurt latency dependent applications that use very small packets (think VoIP, gaming, SNMP, etc). A more sane way to get the same (or very nearly identical) sequential throughput without affecting such apps, or potentially breaking things, would be to make use of the built-in windowing options in Windows 7/XP. The upshot here is that it's also a lot easier to set up (I turn the Windows 7 commands into a bash file and run them on all new machines myself). If you run OSX or *nix then you already have a much better version of this same setup.


Windows 7/Vista/2008/2008 R2 is simple. Just two netsh commands and you're done. One to enable the proper congestion avoidance setting for larger frames, one to enable a more conservative approach to auto-windowing (so you can fall back to standard frames if a device doesn't like your jumbo ones). In Server 2008 (but not R2) the CTCP setting listed is the default, but we'll run it anyway to be safe. Be sure to run it as administrator if you do make a bash script as you won't get any output to tell you it didn't run correctly. Also, remember to reboot afterwards.
netsh int tcp set global congestionprovider=ctcp
netsh interface tcp set global autotuninglevel=highlyrestricted


Windows XP has auto-windowing built in but it's disabled in the registry because jumbo frames wasn't well supported by network hardware when the OS was released. Paste the following in a notepad window and save it as a ".reg" file to have the necessary keys updated automagically. You will obviously need administrative rights to run this too. It works the same way as auto-windowing in Windows 7 as of SP3 (if you don't have SP3 then it just scales up more slowly). Again, reboot afterwards to reload the network stack.
Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\AFD\Parameters]
"DefaultSendWindow"=dword:00100000
"DefaultReceiveWindow"=dword:00100000
"FastSendDatagramThreshold"=dword:00004000


[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters]
"Tcp1323Opts"=dword:00000001
"TcpWindowSize"=dword:00100000


Just a note, in Windows 8/2012 auto-windowing is set correctly out of the box so nothing to worry about there. Still not worth dealing with the metro/modern UI, but I digress...

My window really slow on my mac, any suggestion guys? :( i dont want to reinstall it thou.

Thanks for post. I need this information to speed up my internet.

thanks for this i tried and it worked for me

Hi
Internet speed is not about computer settings,it's about modem ,cable or wireless connectivity speed.In other words your internet service provider.

 I need this information to speed up my internet.  ;D ;D Thank you.. :D

thank you so much i solved it now

thank you, finally fixed up my problem

lots of thanks for removing my problem.

nice. thanks a lot.
