| i have tried changing my modem and my firewall cant be the reason since my friends experience it aswell on their computer when using my internet. |
I beg to differ. The fact that it does happen to your friends when they plug in on your network (the inference being, it doesn't happen to their computer at home or elsewhere, ergo it's not their computer) points at your router being the issue.
Click on my name above in my response and read my "how-to" guide on troubleshooting wireless issues. The steps on troubleshooting your router are worth trying since they apply to any SOHO router regardless of whether you have wireless or not. Give that a try.
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
