Drop in BT and Wifi connection

I have noticed an increase in dropped connections over my wifi. I remain connected to the router but loose interenet connectivity.Turning on and off wifi on the phone gets me back and running but if i was in the middle of a download i would have to cancel and restart it, Pandora will sometimes have to be restarted as well. At first i blamed my router until i was running bluetooth and wifi at the same time and both dropped connectivity at once, again only restarting bluetooth and wifi on the phone will i get up and running again. I have decided it is not my router since it occurs with bluetooth and i havnt experienced and any drops on my computers. Any ideas!
