Guide Increase Browsing speeds for real

BSNL Broadband: Speeds up from 240kbps to 530kbps
Cable: Speeds up from 128Kbps to 185Kbps
Reliance Wireless: Speeds up from 65Kbps to 133Kbps

I tried it and it was pretty safe on all the three comps, but just in case, exercise caution

Save this file as tweak.reg

Code: 
REGEDIT4
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters]
"TcpWindowSize"=dword:faf0
"Tcp1323Opts"=dword:0

If you want to undo it here it is:

save this file as undo.inf

Code: 
[Version]
signature=$CHICAGO$

[DefaultInstall]
DelReg=Delete_Reg_Entries
[Delete_Reg_Entries]
HKLM,System\CurrentControlSet\Services\Tcpip\Parameters,TcpWindowSize
HKLM,System\CurrentControlSet\Services\Tcpip\Parameters,Tcp1323Opts
Right click on undo.info and click install (to undo tweak)

Reboot ur comp for it to take effect

Some info reg. this:

TcpWindowSize specifies the initial "window" for TCP connections. One side of a TCP connection tells the other side how much data it can send before receiving an acknowledgement. This solves the problem of having to acknowledge every transmission.

The larger this value, the higher the performance, but at the cost of more memory being used per connection. Windows NT 4.0 used a default value of 8760, whereas Windows 2000 doubled that to 17520. This means that Win2k will transfer bulk TCP data faster than WinNT, but use twice as much memory for buffering each TCP connection.

The maximum size of this parameter is 64240 for WinNT and individual interfaces on Win2k.

For best performance, this value should be a multiple Ethernet Maximum Segment Size (MSS).

On Win2k, this parameter can also be set on a per interface basis using HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\interface\TcpWindowSize. On WinNT, this parameter is set on a per interface basis using HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\interface\Parameters\Tcpip

It works well. I havent check the download speed but I used to get arnd 180kbps speed when i did the speed test and now i am getting 298kbps.
Will update on the download speeds tomorrow.

Is there any speed hack for better uploads?
 
hmmm, this is not new,...its also called an 'event 4226 error', whererin when sp2 is installed, it limites the number of tcp connections...theres also a good patch available online you can download , i think its called the 4226eventIDpatch by lvlord. (www.lvllord.de)
now microsoft did this for a reason, simply to reduce the number of connections open to prevent a worm infection to the pc.
opening all 64240 conenctions open basically keeps your pc at a higher risk.
so its upto every individual to decide, how many connections to keep open, this stays valid for only SP2 users, sp1 has no such issue.

cheers
 
Wrong Cowax, this has nothing to do with the SP2 connections limit. These are well known tweaks from windows NT days,the only thing is few people in Inida have ever had success with them.
 
Guys, seacrh for a tool called TCPOptimizer. Has this and also helps u find optimal settings. Never helped me, but it might do somthing for you guys.

I Save It And Then What??Do I Save It In A Particular Folder Or What??
Will It Automatically Increase The Browsing Speed??
I Have SP2.

You double click on the .reg file, the information is entered into the registry. Well... i guess you could say that it 'automatically' increases your browsing speeds. (You will need to restart your system though)

@Kumar: Okay, nothing more on Modem uncapping here then.. :P
