Why does my wireless connection to the internet keep disconnecting randomly?

I have a Dell Inspiron 1525 laptop with:

Windows Vista Home Basic
Service Pack 2
Dell
IntelR) Pentium(R) Dual CPU T3200 @2.00GHz 2.00GHz
3.00GB
32bit

My internet provider is Comcast which supplied me with a Netgear WNR1000 V-2 router. For security I use a WPA-PSK and for the pass month or so I noticed that I am the one who's laptop constantly drops connection from the internet and I don't understand why. I cannot connect in my bedroom either and that has never happened with Verizon DSL which we switched from and I don't understand why. I am right in my living room and my router is in the dinning room and I am still disconnecting. Can someone give me some advice?
