I have wified my computer recently and I use a wireless router supplied by my ISP. It was preconfigured and did not have any connection problems in the beginning. However, for a couple of days, I am getting disconnection problems.

After five or ten minutes, I get disconnected and had to reconnect. The problem is my wireless connection does not continue more than ten minutes.
I am in a fix as I could not understand what happened. Is there any hardware problem or should I call my provider to fix it? Has anyone of you had this kind of problem?

I would appreciate if anybody offers some useful help.
