Strange Internet Speed Problem

I have Windows XP Pro SP3 in My Laptop.
When I use torrents I am able to download at full speed.

But When I browse or download from some websites the speed it slow.
I checked with Mozilla 3.6 and Internet Explorer 7

My Internet Connection Specs:
1. Wireless(EVDO) Connection - Connecting using USB
2. Upto 2.4 Mbps
3. No Fair-Usage Policies

Few notes:

1. Ensured that No Viruses/Spyware in my system - Checked with Updated Kaspersky Internet Security and
2. No Antivirus/Firewall Software limiting my Speed - Checked by disabling the Kaspersky Software.
3. No Speed throttling by ISP as I am getting good speed while using Torrents.
4. Using in my home connection.
5. Ensured the website is not slow/down.Checked with the same connection with another PC.
6. Tried using download managers.But no fruit.
7. No Background network Utilization - updates and of that sort - Checked using TCPView.
8. My browser is set to make 6 parallel connections/server.Tried Increasing and decreasing.Still no hopes.
9. Patched the max. half-open connections to 250.
10. Checked my event logs - nothing Suspicious
11. Have ample free space in my discs.
12. Tried De-fragmenting my harddisk and registry. Still no success.

Also to note that as I get full speeds with torrents there is no problem with ISP
A speed test result from www.speedtest.net at various time of the day shows good results only

Could someone help me to solve this problem ?

 

Hmm, you tried legitamite download managers? I would try FDM (Free download manager) if you haven't, and if that doesn't work well, then I am confused.

But it may be your browser slowing you down. Try using firefox, ie, and google chrome. Trust me when I say this, as I fix laptops: chrome is indestructible. It runs smoothly an the oldest, slowest, virus infested laptops out there. If it's slow, you got a hardware or Internet problem.

This area is a bit fuzzy to me, but it could have something to do with the ports your computer uses for Internet. The randomly generated ports for torrents, for example, may
work fine, while http ports may be... Disfunctional.

You could also try opendns temporarily, but it may not be
Effective.

Also Make sure
That your firewall is turned off, and if it is, re enable your security and do a quick malware scan.

 

What no one is going to say forum rules prohibit us from helping users with P2P downloaders onboard?
You know that at least caused the issue because it enables access to the worst elements on the internet.
