My Laptop is not optimized for Broadband

Hi

I occasionally check my laptop on Pc Pitstop site

click here

which gives a free check up. Today I got this message about my internet connection:

Bandwith Down: Rated Speed 1000 Tested speed 286 (Kilobits/second)
Receive Buffer Size
Your receive buffer size is currently set to the system default. The default value usually does not provide the best performance.

If you are running Windows XP or prior, your operating system is not optimized for broadband internet access. Amazing as it seems, this computer is optimized for a dial up modem. Furthermore, it is not possible to achieve your broadband providers top speeds without adjusting your internet settings. Once you do, the performance improvements are enormous, particularly in downloading large files such as video and audio streams. All large web pages will appear faster, and of course your PC Pitstop test score will improve!

Technical Explanation
Windows uses the receive buffer to temporarily store packets it receives from the Internet. Its size can be configured via a registry setting. Different Windows versions use different default sizes for this parameter. The faster your connection and the higher your connection's latency, the bigger the receive buffer needs to be. Dial-up modem users generally do not benefit from adjusting this buffer size "

It suggests using its program (which you have to buy) to optomize it, or gives some manual suggestions:

"This manual adjustment changes the TCP Receive Window size and is recommended only for cable modem or DSL users running Windows XP or Windows 2000. To adjust more settings, or if you are running Windows 98 or Windows Me, we suggest using a software application like PC Pitstop Optimize to make sure all settings are adjusted properly.

To change your TCP Receive Window size:

Launch window registry editor by clicking on Start | Run .
Click in the Open dropdown box and type in regedit.exe then click OK .
Back up your registry by selecting File | Export type in a meaningful file name, in the export range section select All and save to your hard drive. To restore your old registry you simply import this file.
Next you need to create a new registry key. On the left side you need to go to the directory HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters
Select Edit | New | DWORD Value
Rename the new registry key to TcpWindowSize.
Modify the registry setting for TcpWindowSize by double clicking on the key.
Change the Base Setting to Decimal.
Enter the value 64240 and click OK, then exit RegEdit.
For these settings to take effect you need to close all your open applications and reboot your system. "

Naturally I dont want to buy anything(!) and am wondering how best to carry out the optimization needed to improve my system. Anyone have similar experience or suggestions? Its a fairly new laptop, XP Pro, 2 gig ram etc

What ISP are you with and are you using a modem or ADSL router?

It looks to me as if PC Pitstop is just after your money. Also, unless you know what you are doing I do not advise messing with the Registry.

its a local wireless company. Im receiving it via a dish thing on my house, from a local hill! Then I have a router. There is a modem in the laptop and a wireless card of course also.

In fairness PC Pitstop does give a thorough check. And dont really push their products as such.

I just thought if its set up for a modem I could improve things perhaps. But to me its working fairly fast.

TCP receive window can be changed at the bottom left of the main screen. You should also back up the settings.
