Making your Windows XP broadband faster

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

REQUIREMENTS: MALAYSIAN USERS; WINDOWS XP; AT LEAST  512MB of MEMORY;

Faster for browsing ONLY, not downloading as Streamyx is throttling the speed of many websites such as megaupload, rapidshare,  etc.  So, don’t blame me if your downloading speed is not consistent, sometimes fast (over 50Kb), sometimes slow (below 15Kb). It is your luck!!! It depends on your auto-configured server IP and/or Fair Usage Policy. Click here for my speed test.

Go to forum at lowyat (click 1, http://forum.lowyat.net/topic/943607) (click 2, http://forum.lowyat.net/BroadbandUser-2-User) for more comments by other people.

Streamyx(click), Celcom(click), Maxis (click) and P1Wimax (click) have this policy, Fair Usage Policy (Tahap Penggunaan Adil), i.e. after downloading files for a certain number of GB, the overall speed is reduced to a very very very slow one for a certain period of time. Call your provider to know more about the policy.

After applying the new settings, sometimes my Streamyx 512k broadband (Package RM66) shows a tremendous speed in browsing and downloading. Most of the time, it is slow. It’s your luck. At least I can enjoy fast speeds from time to time after tweaking the settings.Click here for my speed test.

162KB/sec… I have nothing else to say…
