How To Speed Up Your Broadband Cable Modem or DSL Connection

Ever wondered if you are able to speed up your internet connection for free?

Many computer users have faced the issue of slow network performance or slow internet connection speeds. What if you were able to speed up your connection without paying for additional internet provider services? What if you are able to speed up your current internet connection through a few registry tweaking steps? Well, today is your lucky day because we will demonstrate one way of speeding up your internet connection through a simple registry tweak.

If you have either a broadband cable modem or DSL connection, this process should work for you. This procedure will also work in the case that you utilize a router, switch, network hub or access point. After performing the steps below you it may speed up the way your computer accesses the internet through your connection instead of actually changing anything on the side of your ISP (Internet Service Provider).

Steps to optimize or speed up DSL and cable modem connections

  1. Go to the Start menu and select Run.
  2. Type in Regedit and click OK.
  3. The registry editor should be open now. Navigate to the following path using the folders on the left panel of the registry editor program: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters
  4. Create the following DWORD values if they are not present by right clicking on an empty space on the right side panel of the registry editor. Select New > DWORD value.
    DWORD values to create:
    - DefaultTTL
    - EnablePMTUBHDetect
    - EnablePMTUDiscovery
    - TcpWindowSize
  5. After each DWORD value above is created you must set the Value data of each (by double clicking on each new DWORD value that you created) as follows:
    DefaultTTL - Value data= 80 Hexadecimal
    EnablePMTUBHDetect - Value data= 0 Hexadecimal
    EnablePMTUDiscovery - Value data= 1 Hexadecimal
    TcpWindowSize - Value data= faf0 Hexadecimal
  6. The end result should look like this:

  7. After each new DWORD value is created and each Value data field is completed you may close the registry editor program and restart your computer.

This completes the process for speeding up your broadband cable or DSL connection.

    I didn't tune my PC... I upgraded my wireless card and rebuilt the wiring to the house to reduce interference and ensure the direct line is tapped directly to the modem.

    We have a wireless N router. My father is connected via Ethernet cable. I am wireless, and I get not only a full signal from the opposite side of the house, and I boosted the internet speed from 8Mbps to 30Mbps.

    Check your hardware at the modem before tuning your PC. Machine before software. ALWAYS!
