Since Thursday last week, I'm almost experiencing constant internet connection failure. Thursday morning I turned on the computer, and then it all began:
I was online for about 5 minutes, and then I began to receive the message: Cannot find server. So I had to reset the modem, and after that my internet connection was stable again...... for 5 minutes. It went on and off, on and off, etc.
At first, me and my mother thought the provider had some technical difficulties or work-in-progress or something, but according to their website that didn't seem to be the case. Throughout the day, my connection keep failing, in the same patern as I described above.
Friday: The exact same problem. My connection kept switching on and off, on and off. My mother had the same problems on her laptop. My cable connection is connected to my computer via a router, so all the problems I had, my mom had too. Friday night, about 19:00, I resetted the modem again, and my connection was stable for about 4 hours.
Because of my mom's problem with the wireless internet connection on her laptop, a computer technician came to our house. He wired a cable to the laptop, via the router, and the wireless internet problem was solved. We told him about the failing connection and told him that it wasn't work-in-progress of the provider. He thought it may be the cable modem itself, since the connection was established again after the modem was resetted. But then the internet on my computer failed, while my mother had still a flawless connection. So the technician thought it must have been my computer that jammed the signal. He connected a brand-new router, and the problem wasn't solved. After that, he inserted a brandnew network card in my PC, and the problem still wasn't solved. He thought it may be some spyware or something like that. I thought it wasn't the case, but he advised me to completely format my system. And so I did, I re-installed Windows XP, and after that I turned on Internet Explorer. It didn't work at all. Normally it said 'Finding location .....', but I received a completely white screen, while my mothers laptop still had a flawless connection

After that, internet still didn't work. I resetted the cable modem, and turned it on again, after that, the connection was stable for about 4 hours. During that time I installed several programmes: AVG Free, Ad-Aware SE, DivX Player, Windows Media Player 10, VLC Media Player and Winamp.
Shortly after that, the internet connection failed again, also the connection on my mothers laptop.
So, naive as she is, she blames me for the failing connection! She says that it must have been one of those programmes I installed. But I have had those programmes for ages on my PC, with no problems.
At this momemt, my connection is stable, for as long as it lasts.
When it fails, I must reset the modem, and than it usually works again.
What could be the problem? My network card? The cable modem?
Please help! It's driving me crazy!
